Getting started with the Galaxy A54 5G: Samsung’s mid-range phone gets a makeover – CNET France – CNET France

The new look of Samsung’s $499 phone makes it look more like a premium device.

THE Samsung Galaxy A54 5G To much in common with its predecessor. It costs 499€ and starts on April 6th. It brings a new design, a new processor and a new camera to the program.

This visual overhaul seems to be the biggest change. This might not matter much if you’re planning on putting a case on your device, but it does suggest that Samsung is doing more to narrow the gaps between its high-end devices and its cheaper devices. This could be particularly important if Samsung wants to catch up Google Pixel 6aone of the benchmarks in the middle class.

The new look of the Samsung Galaxy A54 5G

Richard Peterson/CNET

The Galaxy A54 5G has features with new paintwork giving it a more upscale look than that Galaxy A53 from last year. The glossy back and matte edges remind us of theiPhone 11And that’s good.

The integration of photo sensors is inspired by what can be found on the Galaxy S23 series. Looks aren’t the most important aspect of a phone, but it’s always nice to see a sub-$500 device that doesn’t look cheap.

It almost feels like Samsung is taking design cues from Google. The $459 Pixel 6a, which is essentially a cheaper version of the Pixel6, also has a glossy finish. And like the Galaxy A54 5G, the Pixel 6a has its photo sensors in the same way as its predecessor.

The Galaxy A54 5G has a 6.4 inch screen, making it slightly smaller than the 6.5-inch Galaxy A53 5G. We always thought this size was a good compromise between that Galaxy S23 6.1-inch and the 6.6-inch Galaxy S23 Plus, and the same goes for the Galaxy A54.

The Galaxy A54 5G runs on a newer processor than the A53 5G Exynos 1380, which is probably the successor to the Exynos 1280 featured in the latter. We haven’t spent enough time with the Galaxy A54 5G to know if this new chip brings significant improvements. But during our brief visit to the device, the services seemed to us quite correct. Apps open and close quickly, the camera launches almost instantly, and the keyboard pops up right away.

The camera is the main difference between the Galaxy A54 and the S23

There are many differences between Samsung’s affordable A-series phones and the high-end S-series phones, with camera equipment still being the biggest. The Galaxy A54 5G comes along 50 megapixel main sensor, 12 megapixel ultra wide angle and 5 megapixel macro. There’s no telephoto lens, so the Galaxy A54 only has 5G 10x digital zoom.

The Galaxy S23, on the other hand, offers a 50-megapixel main camera, a 12-megapixel ultra-wide-angle and a 10-megapixel telephoto camera. While wide-angle and ultra-wide-angle look similar on paper, we wouldn’t be surprised to see noticeable differences in image quality. the chips Qualcomm Snapdragon 8 Gen 2 The S23 range, which has been optimized for Samsung’s Galaxy phones, probably plays a big role in handling photos.

Samsung’s Expert Raw app cannot be used on the Galaxy A54 5G either. However, the photo configuration is what you would expect from a phone at this price point. It has even more to offer than thatiPhone SE 2022 for €529, which only has a 12-megapixel rear sensor with 5x digital zoom.

Overall, the Samsung Galaxy A54 appears to be 5G a promising option for anyone looking for an Android phone under $500. But we’ll have to spend more time testing it before we know if it’s worth recommending.

“We have to buy a new one. We often get this answer when we want to have our phone or laptop repaired, for example. “But between 70 and 80% of breakdowns are fixable,” assures Zakari Bouazzaoui, co-founder of high-tech repair shop Kapptech Lille. With his partner Yassine Badiaa, they make “Advanced Repair” their spearhead. Because that is what distinguishes them from other workshops: “The others change screens, charging plugs or take care of changing the battery while we micro-weld to get to the root of the problem.”

Repair instead of consuming too much

Since the start of their activities last November, the two partners have only had one word on their lips: recycling. “We urge customers to repair their old devices instead of using too much,” says Zakari Bouazzaoui. A way to extend the lifespan of our devices as society becomes more vigilant about over-buying. And everything works: smartphones, computers and even game consoles. In addition, beyond the repair component, Kapptech offers some refurbished devices according to a best practice: “We test it, we approve it and we offer it for sale. »

The two young entrepreneurs hope to find their customers while the work in progress on Boulevard Carnot is delaying their start… While waiting for the end of this project in the spring, they rely heavily on social networks: on us, and especially on that we can… fix the irreparable! »

Google maintains vagueness about future of Fitbit brand La

Google maintains vagueness about future of Fitbit brand – La Voix du Nord

Fitbit and its Sense and Sense 2 watches have been owned by Google for two years, which just launched its own connected watch. What is in question about the future of the American brand bought 2.1 billion dollars.

Through a particularly sibylline email this week, Fitbit watch and band users learned that starting April 1st (and I’m not kidding) the Deezer and Pandora apps would be removed from the watch. “This means you can no longer download Pandora stations or add Deezer playlists to your device or listen to previously downloaded content,” says Fitbit.

Closure of Fitbit subsidiaries in France, Sweden or Germany

Even if music isn’t the main feature of the Sense and Sense 2 watches, which primarily focus on sports, health and well-being, this announcement is enough to keep the future of the American brand acquired by Google a little more vague on January 15, 2021 for more than $2 billion. Especially since this email comes a few days after the publication of an article by our colleagues from Informed announcing the closure of Fitbit’s subsidiaries in France, Sweden or Germany. Your own communication is also finished, everything has been internalized in the Mountain View giant.

Fitbit has yet to say its last word

Enough food for thought for all those who believe that Google’s acquisition had no other goal than to get their hands on the brand’s know-how to develop their Pixel Watch. A smartwatch that, according to the research agency Canalys, sold 4 million copies (by the way) in the last quarter of 2022, which puts Google in second place in the list of consignors of connected bracelets, just behind Apple.

But Fitbit hasn’t said its final word yet. The application will be improved using Google technologies to “develop new features and reduce loading times”. It also announced that certain features of the “Premium” subscription (data history) would become free. A good omen?

Samsung Galaxy Z Fold 5: hinge, S Pen… everything we know about the foldable smartphone – Frandroid

A new generation of Samsung’s largest folding smartphone is expected to see the light of day later this year: the Galaxy Z Fold 5 and its folding display in book format. If the smartphone is not expected until the summer of 2023, dozens of serious rumors have already surfaced online. We take stock of the hypothetical spec sheet of Samsung’s next most expensive smartphone.

Since the first Galaxy Fold in 2019, it has become an annual event. In 2023, the South Korean manufacturer Samsung is expected to launch a new version of its foldable smartphone: the Galaxy Z Fold 5. Four years after the announcement of the first mobile phone with a foldable screen, Samsung will have successively improved its recipe to make its Bringing fans the best of mobile technology. But the company is no longer alone in the market and after a Galaxy Z Fold 4 very similar to the previous one, Samsung must therefore update its range to confirm its lead.

According to South Korean media The Elec, an internal meeting detailed the points to be improved from November 2022: “to make the phones lighter and thinner and more durable, to reduce the crease on the screen, to have a specific location for the S Pen and improve the camera”. We will see that if some goals seem to have been achieved, not all of them have. We summarize everything for you.

The first waterproof teardrop hinge

Earlier this year, in our letter to Dad Samsung, we kindly asked that he “keep on with the folding chairs” for 2023. It is quite clear that it is catching up with its competitors, especially in terms of screen technology. Whether it’s Oppo with the Find N2 or Honor with the Magic Vs, these two Fold smartphones released in late 2022 have a screen that leaves a much less noticeable crease mark than the Galaxy Z Fold 4, while leaving no gap between the two halves of the smartphone inside closed state.

Samsung Electronics plans to apply the “Droplet” hinge structure to the Galaxy Z Fold 5. Samsung calls it a “dumbbell” hinge internally. Waterdrop hinge + waterproof is finally here.

— Ice Universe (@UniverseIce) January 15, 2023

Samsung seems to have listened to us! Or rather, after adapting to the innovations of its competitors: mid-January 2023, a first tweet from the leaker ice universe claimed that the next Z Fold 5 would feature a new “teardrop” hinge, dubbed the “anvil hinge” by the company, while being as waterproof as the Z Fold 4. Information also mentioned by South Korean blog Naver in the same period, then repeated once again by Ice Universe End of February. Probably, because the South Korean manufacturer already patented a similar technology in 2016.

1677500668 707 The Galaxy Fold 5 and Flip 5 would have aThe patent sketch of a teardrop design filed by Samsung in 2016. // Source: Samsung via Naver

It’s the same technology that powers Oppo and Honor smartphones, but their models aren’t waterproof. Samsung offers the best of both approaches: a hinge that leaves little trace on the screen and completely closes the smartphone while maintaining the “IPX8” water certification, according to a tweet from Samsungice universe Released late March 2023. The “X” of this certification, on the other hand, means that the smartphone still does not promise protection against dust. Enough to be a step ahead of its competitors internationally … and simply adapt the hinge of the new Huawei Mate X3 in the Chinese market.

First shots with tweezers

This rumor can also be found in unofficial 3D renderings of the upcoming smartphone. At the end of March 2023, the YouTube channel of technician shared on Twitter computer-generated images of what the Samsung Galaxy Z Fold 5 could look like, based on information from the South Korean leaker and youtuber Super Roader.

— Technizo Concept (@technizoconcept) March 22, 2023

In these images, the product has almost identical dimensions to the Z Fold 4, but folds nicely without leaving any space between its two halves. A design consistent with previous rumours, but to be taken with caution for lack of accurate sources.

A template that may not change much

Because of this hypothetical new hinge, some dimensions of the Z Fold 5 should be reduced. While Vietnamese site The Pixel mentioned a smartphone in January 2023 that was perhaps heavier than its predecessor, going from 263 to 275 grams, the leaker is ice universemore reliable, said in a message published on his Twitter account in late March 2023 that the phone would instead be lighter: a product that would weigh “254 grams,” which is 9 grams lighter than the Z Fold 4. If confirmed, however, that small difference might not even be felt in the hand.

In the same tweet, Ice Universe also hinted that the thickness of the Z Fold 5 would also change with a possible new hinge: “After folding, the gap [entre les deux moitiés d’écran] disappears and [le smartphone] getting thinner,” according to the leaker, from 15.8mm to “13mm.” The same applies here: If this change is visually noticeable, Samsung’s largest folding smartphone will continue to take up space in your trouser pocket.

Finally, the size of the smartphone’s external screen could remain the same. ice universe also claims in a tweet published in early March 2023 that the Galaxy Z Fold 5 would come with a “6.2-inch” panel like the Z Fold 4. It’s not specified if the screen will keep the same 23:9 ratio, but we can guess. This fifth model of the Galaxy Z Fold could therefore remain narrow in use when folded.

A more innovative touchscreen?

Another hallway noise passed by this universally reliable leak: a “new touchscreen technology” mentioned in his summary of the rumours, posted at the end of March 2023. This information would mark a significant change compared to previous generations of the Galaxy Z Fold, but the wording remains too vague to draw any conclusions at the moment. However, other rumors could say more in the coming months.

S Pen or not S Pen, that is the question

The presence of a long-awaited feature for fans of Samsung’s foldable smartphone has been discussed in recent months, according to rumors. While it’s already possible to use an S Pen stylus on the Galaxy Z Fold 4, the phone doesn’t offer a storage option as was the case with Samsung’s Galaxy Note range.

Two rumors spread by South Korean media The Elec in November 2022 and then by Vietnamese site The Pixel in January 2023 claimed that the Galaxy Z Fold 5 could be the first generation to allow the stylus to be locked in the smartphone stow away However, an article published by the South Korean news site ET News in early February suggests that after several internal tests, Samsung finally decided not to include this novelty. According to the media, the question is: the space that a possible new hinge will take up. Samsung wouldn’t have given up on the idea, but it will have to wait for a next version of the Galaxy Z Fold to see this.

A probable rationale, although we’ll await the final design of the Galaxy Z Fold 5. Then again, it’s likely that Samsung’s next folding model will retain S Pen compatibility even without a slot.

Conflicting rumors about the photo

Another source of many rumors: the photo modules of the next Z Fold 5. As of July 2022, South Korean media The Elec (via Android Central) put forward that two of the next smartphone sensors could be improved. If the Galaxy Z Fold 4 is the first model in the range to offer a 50-megapixel resolution for its wide-angle camera, The Elec then claimed that the other two modules (ultra wide-angle at 12 MP and telephoto at 10 MP) would also get their definition up increase the same value.

In mid-January 2023, it was Vietnamese media The Pixel’s turn to claim that the main wide-angle sensor could switch from 50 to 108 megapixels, as has been the case for several Samsung flagships since 2020. Information that doesn’t seem too far-fetched.

However, the treat ice universe contradicted this information on Twitter in early March, stating that the Z Fold 5 would be equipped with the “same module” and that it was “impossible to use the HP2”, i.e. the 200 megapixel module available on the Samsung Galaxy S23 Ultra , released February 2023. The wording remains rather imprecise, but we can conclude that it is the main module, hence the same current 50 megapixel wide angle.

Galaxy Z Fold5 will continue to use the same camera module as Fold4. It is impossible to use HP2.

— Ice Universe (@UniverseIce) March 10, 2023

The doubt therefore remains, but the more recent nature of this latest information suggests that the next Z-Fold may not change its choice of photo modules. This decision wouldn’t be surprising either, since the definition of the wide-angle camera has already changed between the Z Fold 3 and Fold 4, it’s rare for Samsung to update its sensors two years in a row.

A state-of-the-art Qualcomm processor

The very first expanded information on this upcoming Galaxy Z Fold 5 arrived earlier this year. Again, South Korean news site The Elec claimed to know the next processor to be integrated into the smartphone… from July 2022!

The Galaxy Z Fold 4 hadn’t even come out yet when the media was already talking about a Qualcomm Snapdragon 8 Gen 2 chip for Samsung’s next two folding models, the Galaxy Z Fold 5 and the Galaxy Z Flip 5. An announcement maybe premature, but more recent Time confirmed by leaker ice universegenerally reliable, in a tweet posted in mid-March 2023.

Credible info as all previous Galaxy Z Fold models came with Qualcomm’s latest premium chip. Therefore, after our tests of this processor, we can assume that the smartphone is faster and more responsive, but moderately warms up even during long gaming sessions.

Same but more modern storage options

The storage capacity variants on offer could also remain the same: according to a source quoted by the specialist site Sam Mobile at the end of February, the Galaxy Z Fold 5 could be available in 256 GB, 512 GB and 1 TB versions … the same choices as the Z Fold currently offers 4 offers.

However, all storage options for the fifth generation of Samsung’s folding smartphone could offer UFS 4.0 flash storage technology, according to Sammobile. Compared to the Z Fold 4, this standard would double the speed of reading and writing files.

Some characteristics we can guess

Even without rumors from the corridors or sources close to the manufacturer, we can imagine without too much risk that certain characteristics of the Z Fold 4 will stay the same with the Z Fold 5 or logically evolve towards the latest technology available.

First, in terms of the operating system. Galaxy Z series smartphones have always integrated the latest version of Android available at the time of their release; the Galaxy Z Fold 5 should therefore be sold under the Samsung One UI 5.1 based on Android 13. The South Korean manufacturer also offers four major Android updates and five years of security patches for newer models.

On the other hand, if we don’t know yet whether the size of the internal or external screens will change, we can assume that they retain both Amoled technology and the 120Hz refresh rate present on the Z Fold 4 and are still below the best in the premium smartphone market.

Eventually, Bluetooth connectivity would naturally evolve towards the latest version of this technology, from Bluetooth 5.2 to 5.3.

A price that is likely to remain high

No media or leaker has given an exact retail price for the Galaxy Z Fold 5, but we can still assume that this model, like its predecessor, will be one of the most expensive smartphones in the world. Innovation comes at a price: the Z Fold 4 was marketed at 1799 euros when it was launched in France in August 2022.

If the technical improvements rumored to be confirmed, the selling price could even rise, given the rise in the price of raw materials and consumer goods. Therefore, based on the projected inflation for 2023, we can assume that the product will be sold between 1800 and 1900 euros.

When will the Samsung Galaxy Z Fold 5 be released?

Samsung usually announces its two folding smartphones in the Galaxy Z series around the same time every year. Be it the Z Fold 2, 3 or 4, all were officially unveiled in early August. This could therefore still be the case for the Z Fold 5, which is expected in early August 2023.

Likewise, the last three models were then marketed two weeks after their presentation. The Samsung Galaxy Z Fold 5 would therefore be sold from mid-August 2023.

OVH Will a 20 year old revolution be the key to a

OVH: Will a 20-year-old revolution be the key to a greener grid? – 01net

Between Lille and Roubaix we find Croix, a town where the brick walls of the north contrast with a changing sky, blue for a sigh or mottled with well over fifty shades of gray. The OVH factory in Croix is ​​located in an industrial area such as there are many in France, but above all in this former large industrial area. We could sweep the information away with the back of our hands, but that would miss the point. This site manufactures, assembles, disassembles and tests the servers that operate or have operated the group’s data centers around the world, excluding those in North America as another factory of this type exists in Canada.

Water cooling, gloomy plane?

The Cross factory doesn’t look like much. The buildings are functional and could well be obtained from the neighboring tractor manufacturer. Just an OVH Cloud sign on a barren lawn and maybe a few nice cars, including a shiny Tesla, and electric charging stations in the parking lot indicate we’re in one of the French cloud giant’s nerve centers. .

01net already had the opportunity to visit this factory last year and if we came back it would be for a special anniversary. That of 20 years of water cooling or water cooling with OVH sauce. A somewhat counterintuitive technology, since water and the electricity that powers the computers don’t really mix. However, OVH has made it its spearhead, a technological and ecological argument.

This anniversary took place without candles and party favors, as did the birth of this technology, secretly coming into the world without fanfare or trumpet. “We had a confidential approach, we didn’t announce at the beginning that we would do water cooling,” recalls Miroslaw Klaba with a childish smile on his face to those who made a good joke. Octave’s brother, CEO and founder of OVH, is primarily responsible for the group’s small R&D team, which occupies part of the Croix factory site. He continues: “At one point Octave had sent out a press release announcing that we were making liquid cooling before he backed down and hid behind the April Fool’s joke excuse. “For what? Because the world wasn’t ready to take the plunge.

It must be said that OVH’s approach to water cooling, brilliant as it may be, looks like a DIY that has become a well-kept industrial secret, protected by several dozen patents, some of which are still being validated.

01net.com – One of the copper “plates” that cools CPUs or graphics processors in OVH servers thanks to water.

The water that does not lack air

Because OVH follows its own path, between extremely controlled and reproducible industrial processes, star-eyed geek hacks and a scientific approach overseen by a fluid mechanics and thermal energy doctor, Ali Chehade, who recently signed an intriguing post at OVH hat blog highlighting, among other things, the importance of making water use more efficient in data centers.
Thus, copper water radiators, designed by OVH teams and manufactured by a partner specialized in metallurgy, are made to order and made to measure for the different types of servers that OVH prepares or overhauls.

These servers don’t just rely on airflow to cool their components, let alone the two main elements, the CPU and GPU, which account for between 40% and 70% of the calories generated. OVH servers use an internal and closed hydraulic network that circulates throughout the rack and leads to a rear cooling system. Based on the principle of car or refrigerator coolers, it is used in particular to cool the hot air produced by the RAM or the power supply of the server, which is sucked in at the back of the server and cooled by copper spirals filled with water, again. Air and water coexist to cool the configurations abused by our needs as Internet users.
And for those worried about seeing copper tubing bloom in a data center, note that each rack can be assembled and disassembled without the risk of leaks, thanks to a system of O-rings that won’t let the slightest drop through, they said we. Guillaume Hochard, Head of Server Manufacturing at OVH.
The former safety expert in the nuclear, gas and oil industry is obviously aware that leaks can occur. However, he ensures that they are rare and reduced by checking for leaks at different points in time during production and assembly – the circuit containing the water is repeatedly pressurized with five to six bar in order to see if it holds up – while new welding processes were introduced to prevent leaks where multiple parts fit together.
A little further on, Guillaume Hochard proudly showed us an assembled server, almost ready to be sent to a corporate data center – a “DC” as the OVH managers we spoke to call them. “We’re the only ones doing this,” he said. This phrase fills the pride of a David who would stand up to many Goliaths, we heard it often during our visit to OVH. Anyway, “it” in this case was a latest generation Nvidia graphics card, completely stripped, stripped of its case, bare attached to the structure. A hard-to-see card and of course covered with a home-made heatsink that’s water-cooled.

OVH – A server cabinet under construction.

Totally bespoke

No fewer than 300 water-cooled servers are produced every day in the Croix factory. The result of a thoughtful and refined Taylorism, the result also of a vertical integration, since the company that makes the racks for the servers on demand rents part of the Croix factory site to be right next to its customer. This proximity is apparently made possible by the fact that the company in question is “the property of Mr. Klava”, explained Guillaume Hochard. If Octave and Miroslaw are Octave and Miro to almost all employees we have met, Mr. Klava denotes the father of Octave and Miroslaw. A good way to remember that OVH, as big as it is, remains shaped by the Klava family. A family and a new dynasty from Roubaix, after the textile kings of the 19th century, whose gigantic residences still line the Avenue Jean Jaurès bordering the magnificent Barbieux Park in Roubaix.

Of course, this proximity allows us to cut costs, but also to be much more reactive. So it has happened more than once that a team member had the idea in the morning to plan a server prototype and be able to test it that same evening, we were told during a site visit.

OVH – An alley in one of the Roubaix data centers. You can see the back of the server racks with the copper pipes that supply them with water.

green water

The introduction of water cooling was originally motivated by a desire to reduce costs. None of our interlocutors at OVH hid it. The reduction in the number of fans required to run a server, the stacking of up to four rack levels that can accommodate 48 or 96 racks without having to costly air-condition data centers, all this is accompanied by a significant reduction in the bill for OVH and its customers.

But even better, at a time when the focus is increasingly on the green line, this reduced power consumption is a first-class ecological argument. It is even a kind of ecological cluster bomb, where different layers accumulate…

The use of water cooling means that OVH’s data centers are very different from the image we have of a data center with a clean room and frozen air conditioning. The French cloud giant’s “DCs” are “out of water and out of air” hangars that work with free cooling, i.e. without energy-consuming air conditioning, explains Grégory Lebourg, director of environmental programs at global level and former head of corporate infrastructure.

“Buildings don’t have to be watertight, don’t have to be hydrometrically controlled, etc. he continued. When OVH needs to build a new data center, “it’s very easy for me, I take buildings that are in disrepair whenever possible,” he joked, trying to get people to understand that water cooling ensures the servers run at room temperature in a room where they are are in winter it is around twenty degrees. Of course, work is done to ensure that the roof is waterproof, the floor is perfectly level and everything meets safety standards, especially against burglary… and fire. But unlike most DCs, there’s no need to build huge buildings with huge floor plans. The Roubaix 8 data center thus occupies old brick buildings that have certainly had one or more lives.

While OVH’s DCs obviously need to be close to a power source, they don’t necessarily need to be built close to a water source like some of Google’s green data centers. These buildings, for example, take water from a river to cool the thousands of machines they contain before draining it after cooling it as best they can. At OVH, in data centers there are tanks with a capacity of a few hundred liters every two or three aisles, and everything works in a closed circuit.
Water losses only occur on “hot days”, roughly speaking in summer when it is scorching hot. Water is then vaporized or poured in drops on the adiabatic radiators located outside the buildings, where the water heated by its passage through the servers is sent to cool before returning to water-cool the computers running 24 hours a day.

OVH – OVH data centers can be “simple” hangars…

The Fact “Electricity”.

“The great interest in this device [de watercooling, NDLR] is that it allows us to condense the number of servers per square meter,” argued Grégory Lebourg, and it also allows us to display a PUE (energy use efficiency, as defined by the international standard ISO 30134-2 since April 2016). ) extremely low Schematically speaking, a PUE of 2 means that one watt is used to cool the IT equipment for one watt of power supply for the same IT equipment.
However, the PUE of OVH’s data centers would average 1.28, compared to an industry average of 1.57 in 2021, according to a report by the Uptime Institute, which is a reference on the matter.
This PUE of 1.28 is exceptional – although giants, including Google, like to report PUEs of less than 1.1. OVH thus achieves 50% energy savings compared to a traditional data center.
But the PUE is not the only criterion that OVH specifies, the water usage effectiveness or efficiency in water use is also important. Where traditional data centers use an average of 1.8 liters of water per kWh, OVH’s use an average of just 0.26 liters of water. Less electricity, less water, water cooling is a miracle solution… And these first twenty years would be just the beginning…

OVH – Views of an “immersed” hybrid server.

The future of water cooling belongs to oil…

In fact, the pairing of water cooling and air currently trending at OVH could soon be replaced by a new approach that the cloud specialist has been working on for some time and that it presented last October: Hybrid Immersion Liquid Cooling. This approach, which the French are touting as the future of data centers, still involves water cooling of the hottest components, but replaces the air with a dielectric liquid – meaning “it doesn’t conduct electricity,” a kind of oil,” Miroslaw explained to us Klaba.
The components, arranged in vertical racks, are therefore immersed in this liquid, which cools them by natural convection, while the copper pipes continue to carry water to the processor and graphics processor of the servers to lower their temperature during operation.

These new bays, which can accommodate up to 48 servers arranged like books in a library, can allow the operation of machines with input temperatures in the data center of up to 45°C, according to OVH. This means that at lower temperatures, it’s possible to charge more of the same configuration or use less to cool it. Even better, the total consumption of the cooling infrastructure of OVH data centers could be reduced by at least 20.7% thanks to water cooling compared to what is currently achieved, estimate the French company’s experts. OVH promises a partial PUE of 1.004.

After 20 years of developing his invention and convincing, hybrid water cooling with immersion seems to be a new technological eldorado to make data centers efficient and consume less energy or water. At a time when the explosion of generative artificial intelligence is clearly raising the issue of cloud overwhelm, OVH seems to have a green solution at hand. A future where everything is swimming in oil?

MSI Prestige 14 Evo review: An efficient and quiet laptop – Les Numériques

MSI is primarily known for its PCs and gaming components, but the manufacturer has offered a variety of computers for office automation or developers for a number of years. The Prestige 14 Evo and its refined design are therefore not aimed at gamers, but at those who want a compact and powerful PC.

Selling for €1,590, it faces stiff competition but benefits from a fairly solid configuration with 1TB of SSD storage and a seemingly beefy Intel Core i7. We have checked all this on our test bench and tell you everything about this PC.

Editor's Rating: 4 out of 5

construction

The MSI Prestige 14 Evo impresses with its simple but rather elegant metal case. The screen format is 16:10 and the borders are not too thick. The 85% occupancy rate is not exceptional as some competitors exceed 90%. We also regret the presence of the fingerprint reader under the keyboard in the middle of nowhere…

It sure comes in handy for quickly unlocking the PC, but it could also have been integrated into the start button, as we often see elsewhere. Otherwise, the keyboard scores with a backlight that can be adjusted in four levels, even if the key travel is a bit long and some will criticize a somewhat soft stroke. The touchpad is smooth but not worthy of high-end models; he sinks too much under the pressure.

The fingerprint reader is inappropriately placed.

The connection is pretty solid with two USB-C Thunderbolt 4 charging ports, a USB-A 3.2 Gen 2 port, an HDMI 2.1 port, a mini-jack port, and an admittedly slightly outdated microSD card reader and fast. Finally, for connectivity, Wi-Fi 6E and Bluetooth 5.2 have been chosen, state-of-the-art standards. The webcam films in Full HD and offers a good level of detail. It’s also compatible with Windows Hello and we can therefore use facial recognition to start a session.

To open this PC, nothing could be simpler: no screws are hidden and all are cross-shaped. You can then change the battery or the M.2 SSD if necessary, but nothing more because the working memory is soldered. We also learn that MSI has decided to install a single fan, which will affect the sequel.

In fact, the Prestige 14 Evo is super quiet! Even under full load with the Cinebench software, we only recorded 33.2 dB, a slight hiss that is good for the ears compared to some of the competition. The warming remains rather restrained at around 40 °C measured in the center of the keyboard. On our thermal images we notice a hotspot at 50°C, but this is at the level of the air outlet, which is perfectly normal. Note that it is not placed on the sides, but under the screen.

Performance

The MSI Prestige 14 Evo is equipped with an Intel Core i7-13700H processor at a TDP of 45W with 14 cores (six powerful and eight efficient), whose frequency can increase to 5 GHz in turbo mode. It also comes with 16GB of DDR5 RAM and a 1TB SSD.

For an office model, this PC does quite well. With a CPU performance index of 129, it surpasses, for example, the MacBook Air M2 or the Samsung Galaxy Book3 Pro 360, also limited by its thinness.

Even more surprising (and disturbing) is that the Dell Inspiron 16 Plus’ Core i7-12700H was much more efficient! A difference of about 15% from the previous generation, which contradicts the promises of a new generation, but is explained by the presence of a thicker case and better cooling on the Dell.

On the Prestige, we saw an average frequency of 2.2 GHz on the performance cores when used intensively with HandBrake. It’s really not much, but it allows the processor not to heat up a lot (57C on average while encoding). As we wrote above, limiting cooling to a single fan is non-trivial: you gain in silence, but you also lose in performance.

So, in absolute terms, the Prestige 14 will be efficient in office automation, but one can wonder why MSI didn’t include an Intel P-series processor, which consumes less and heats up less. The engineers could have also added a fan to make better use of that 13700H, but the PC would have been louder.

On the SSD side, we found 6.5 GB / s in reading and almost 5 GB / s in writing, results worthy of games or very high-end PCs.

Screen

The MSI Prestige 14 Evo’s screen is not its strong point. The IPS panel has a 16:10 format and is well calibrated with an average Delta E of 2.2 and a very good contrast of 1680:1, which is rather rare with this technology. In addition, the maximum brightness reaches 500 cd/m², another good value. Unfortunately, other aspects cloud this beautiful picture.

The average color temperature of 7330K is a bit cold and the screen’s reflectivity is very high (49.5% on average). Why the hell did you put a glossy panel on IPS? Reflections can therefore be annoying, even if the high maximum brightness partially compensates for this shortcoming. Finally, the afterglow time of 23 ms is high, but this is only important in the game, but this Prestige is not designed for that.

Audio

The speakers in this computer are honestly not great. Installed under the chassis, we note the lack of bass, as well as a muffled sound where mids and highs merge. In addition, the stereophonic scene is not very broad. In short, it is better to use headphones or speakers.

The headphone output in particular is very correct with a distortion limited to 0.01%, a dynamic range of 92 dB, an imperceptible crosstalk of -64 dB and an output level of 140 mVRMS. This performance is sufficient for everyday use, but does not allow the use of monitoring headphones.

Mobility / Autonomy

With its 14-inch format, the Prestige Evo is compact. On the other hand, it’s not the lightest as it weighs almost 1.5kg, while adding the 374g of the USB-C charger. The latter is small, but the cable is its weight, and we now prefer “smartphone-style” charging blocks that take up less space.

The charger is compact but the cable is quite heavy.

In the exercise of autonomy, the computer performed quite well. It turned off after 8 hours 13 minutes of video playback on Netflix (via the Chrome browser) with the screen brightness set to 200 nits. A score that keeps him away from bad students without being at the level of the best.

How does the classification work?

The MSI Prestige 14 Evo delivers good overall performance for those looking for an easily portable computer. Its performance is absolutely correct, as is its autonomy, which lasts. Above all, we appreciate its remarkable smoothness even with intensive use. However, you have to make a few compromises on the side of the screen and the construction. We would have wished for full utilization of the onboard processor.
