• Uperfect 23.8-inch dual foldable display offers more screen and less clutter
• Precision hinges and 360-degree folding give users control over their workspace
• Includes USB-C, HDMI, built-in speakers, and a 3.5mm headphone jack

Uperfect has introduced a fresh take on multi-screen monitors for programming, with its stacked dual-screen design, which opens vertically via precision hinges with a 360-degree folding capability, allowing the display to be folded, unfolded, or flipped.

Uperfect says each portable monitor with 23.8-inch panels has a 1920 x 1080 resolution, and a refresh rate of 100Hz.

The Uperfect Delta Mega saves desk space with its built-in stand, which allows for height and angle adjustments while also supporting VESA mounting for flexible setups.

Design, connectivity and ease of use

The Uperfect 23.8-inch dual foldable display supports vertical stacking of two screens, providing an ergonomic advantage and reducing the need for excessive head movements, making it one of the best monitors for trading, or for running video editing software.

The monitors don't include touch functionality, but can be adjusted. When fully extended, they function as a traditional dual-monitor setup, while folding creates a compact, book-like view suitable for presentations, or an immersive reading experience.

One of the standout features is the single-cable connection via USB-C, there's also HDMI, built-in speakers, and a 3.5mm headphone port.

The Uperfect 23.8-inch dual foldable display is currently listed at $649.99, reflecting a significant $550 discount from its original $1,199.99 price.

• DeepSeek R1’s 671 billion parameters run smoothly on the M3 Ultra’s unified memory
• Apple’s Mac Studio proves AI workloads don’t require expensive, power-hungry GPU clusters
• M3 Ultra consumes under 200W, far less than traditional multi-GPU AI setups

Apple’s Mac Studio with the M3 Ultra chip has demonstrated a capability that no other personal computer can match, running the DeepSeek R1 AI tool with 671 billion parameters entirely in memory.

A test by YouTube reviewer Dave2D showed despite using a 4-bit quantized version of the model, it retained its full parameter count and performed smoothly.

The DeepSeek R1 model, a hefty 404GB of storage and high-bandwidth memory typically found in GPU VRAM, is usually run on multi-GPU setups that distribute processing across several high-end graphics cards.

A unique feat: running DeepSeek R1 in memory

However, the M3 Ultra’s unified memory system, instead of relying on external GPUs, uses its 512GB of unified memory to store and process the AI model in a way that no other personal computer can.

Although MacOS imposes a default VRAM limit, Dave Lee manually increased it through the Terminal to allocate up to 448GB for AI processing, eliminating memory bottlenecks and reducing the need for multiple components to streamline AI performance on a single system.

One of the most striking aspects of this test was the M3 Ultra's power efficiency, as it consumed less than 200W while running DeepSeek R1.

The ability to run such a demanding AI model without a multi-GPU setup challenges the industry standard, which relies on high-end Nvidia and AMD graphics cards, as the best workstations and server farms typically use GPU clusters that consume vast amounts of electricity.

Apple’s unified memory architecture enables significant power savings by sharing the M3 Ultra’s memory pool across CPU and GPU workloads, unlike conventional PC setups where VRAM is separate from system memory, maximizing bandwidth while minimizing energy use.

Apple’s Mac Studio, launched with the M3 Ultra chip, features up to a 32-core CPU and an 80-core GPU, making it one of the best LLM workstations and one of the best video editing computers.

• Max added more than 120 new features to its app in 2024
• A WBD survey indicates an increase in design, stability, and personalization
• The service has been rolled out to 73 new countries in the last nine months

Max has been busy making a lot of updates to its app in the last year as part of its global expansion to more countries, but not every new feature is a welcome one.

Of the 120 new features that were added to the Max app in 2024, most are aimed at improving the content discovery journey to finding the best Max movies and best Max shows, but there have also been some less favorable ad-related updates.

These include ads that let you shop for products related to the content you're watching by clicking on a QR code, sponsored content recommendations, and commercials that target 'moments' (not to be confused with Netflix's 'moments' feature that makes sharing content on social easier).

It's an area that many of the best streaming services are increasingly doubling down on as they look for more ways to generate lost revenue from unsuccessful movies and shows. Indeed, Prime Video has also been adding a lot of the same ad features over the past year, making it slowly fill up with even more ads.

Aside from the ad onslaught, Warner Bros. Discovery has been making other changes to the Max app, including enhancements like an improved navigation design on the homepage to make your streaming life easier.

This update moved the navigation tools normally found at the top of a title to the left-side utility menu, making it much simpler to find these options (see the difference this made in the image below).

Global subscribers have also been treated to more ways to find content in the app, even while in the middle of streaming. This feature lets you browse similar titles while watching a movie or show by clicking a drop-down arrow to access the recommendation list.

Like Netflix, Max has also added similar functionality to recommend more movies and shows to watch after you've finished streaming a title. This means that after 25 seconds, if you haven't selected something else, a related genre title will automatically start playing.

Another Netflix feature that Max has added is that titles on the homepage will automatically begin playing the trailer with audio while browsing. I don't know about you, but I can't help but find this distracting while browsing for content and would rather that the audio be muted while the video plays. At least, this feature has only been rolled out to the US for now.

Other US-only features that have been added include the ability to watch five of HBO's linear channels through the app. These include HBO, HBO 2, HBO Signature, HBO Comedy, and HBO Zone.

And, of course, we can't forget the new multiview feature for 2025's NASCAR Cup Series that puts you in the driver's seat that was added to US subscribers' apps earlier this year. It's a great sports feature we're seeing being added to many streamers, such as the Apple TV app and YouTube.

These are just a small portion of the tech updates that Max's streaming app has added since September 2024, but they highlight a lot of the behind-the-scenes work that the service is doing as it looks to expand into more regions.

Max has been rolled out to 73 new countries in the space of nine months and will soon launch on Aussie shores on March 31, just in time for HBO's The Last of Us season 2, which premieres on April 13. However, for those of us in the UK, we'll have to patiently wait a bit longer until we can access all of these great features in the Max (most likely early 2026, going by reports). In the meantime, the best place to stream HBO content in the US is on Sky or Now.

• AMD targets Nvidia’s Blackwell with upcoming Instinct MI355X accelerator
• Oracle plans massive 30,000-unit MI355X cluster for high-performance AI workloads
• That’s in addition to Stargate, Oracle’s 64,000-GPU Nvidia GB200 cluster

While AI darling Nvidia continues to dominate the AI accelerator market, with a share of over 90%, its closest rival, AMD, is hoping to challenge the Blackwell lineup with its new Instinct MI355X series of GPUs.

The MI355X, now expected to arrive by mid-2025, is manufactured on TSMC’s 3nm node and built on AMD's new CDNA 4 architecture. It will feature 288GB of HBM3E memory, bandwidth of up to 8TB/sec, and support for FP6 and FP4 low-precision computing, positioning it as a strong rival to Nvidia’s Blackwell B100 and B200.

In 2024, we reported on a number of big wins for AMD, which included shipping thousands of its MI300X AI accelerators to Vultr, a leading privately-held cloud computing platform, and to Oracle. Now, the latter has announced plans to build a cluster of 30,000 MI355X AI accelerators.

Stargate

This latest news was revealed during Oracle’s recent Q2 2025 earnings call, where Larry Ellison, Chairman and Chief Technology Officer, told investors, “In Q3, we signed a multi-billion dollar contract with AMD to build a cluster of 30,000 of their latest MI355X GPUs.”

Although he didn’t go into further detail beyond that, Ellison did talk about Project Stargate, saying, “We are in the process of building a gigantic 64,000 GPU liquid-cooled Nvidia GB200 cluster for AI training.”

He later added, “Stargate looks to be the biggest AI training project out there, and we expect that will allow us to grow our RPO even higher in the coming quarters. And we do expect our first large Stargate contract fairly soon.”

When questioned further about Stargate by a Deutsche Bank analyst, Ellison gave a reply that could just as easily apply to the cluster of MI355X AI accelerators Oracle is planning to build.

"The capability we have is to build these huge AI clusters with technology that actually runs faster and more economically than our competitors. So it really is a technology advantage we have over them. If you run faster and you pay by the hour, you cost less. So that technology advantage translates to an economic advantage which allows us to win a lot of these huge deals,” he said.

Ellison also touched on Oracle’s data center strategy, saying, “So, we can start our data centers smaller than our competitors and then we grow based on demand. Building these data centers is expensive, and they’re really expensive if they’re not full or at least half full. So we tend to start small and then add capacity as demand arises.”

• North Korea has established a new AI hacking department
• The new group will be called 'Research Center 227'
• North Korea carried out many cyber offensives in 2024, including a fake interview campaign

The Democratic People’s Republic of Korea (North Korea) has established “Research Center 227” according to reports from Daily NK.

This research center reportedly plans to operate “around the clock” to immediately respond to real-time information from North Korean intelligence agencies.

“In late February, the Supreme Commander issued an order to the RGB under the General Staff Department to enhance overseas information warfare capabilities. This order included instructions to establish Research Center 227 for hacking technology research” a source told Daily NK.

Persistent operations

The research center is likely to be focused on "strengthening hacking capabilities” and develop hacking technologies and programs in order to neutralize western cybersecurity systems and critical infrastructure.

These offensives will primarily aim to steal information and disrupt adversary computer networks.

The center will reportedly recruit around 90 computer experts and graduates from high-profile university and doctoral programs, the source confirmed;

“These are not cyber warriors who directly carry out information warfare missions in foreign locations, but internal research staff who develop offensive programs. With the establishment of Research Center 227, the RGB’s cyber operational capabilities will be significantly strengthened in the future.”

Cyber operations in North Korea have been launched increasingly in recent times, especially from the notorious Lazarus group, which has been observed spreading malware through various large-scale attacks, and deploying infostealers to grab credentials from western organizations.

Notably, North Korean hackers have been running the ‘Contagious Interview’ campaign with fake interviews or job adverts which prompts victims to download malware disguised as video conference software.

Also included in this campaign is a series of cybercriminals faking their identities in order to take up software jobs, most likely in order to gain access to critical service systems and information from large western firms, or other fraudulent behavior.

• Dichen Lachman has given her verdict on the Severance season 2 finale's biggest moment
• The actor believes it'll divide the hit Apple TV+ show's fanbase
• She thinks it's going to be difficult to give everyone the happy ending that they deserve

Severance star Dichen Lachman has lifted the lid on the season 2 finale moment that will divide the popular show's fanbase.

Full spoilers immediately follow for Severance season 2 episode 10. Do not proceed if you haven't seen it yet!

Does Gemma finally leave Lumon Industries with her husband Mark? Well... (Image credit: Apple TV+)

Speaking exclusively to TechRadar ahead of the Apple TV Original's latest episode, Lachman said she's just as torn as everyone else will be over innie Mark's decision to choose Helly R over his outie's wife. The latter, of course, is Gemma Scout, aka the outie persona of the character that Lachman portrays.

The final installment of Severance season 2, titled 'Cold Harbor', is full of incredibly significant moments. You can read more about everything that happened in my Severance season 2 episode 10 ending explained piece.

By far the most consequential incident, though, takes place in the season 2 finale's last five minutes. After rescuing Gemma, Mark S (i.e., Mark's innie) and Ms. Casey (one of Gemma's multiple severed personas) make it to the severed floor's exit stairwell.

There's a severance barrier installed in this doorway. So, as long as the pair leave, their outie personas will take over, and they can seemingly leave Lumon for good and get their Happily Ever After moment.

That's where things take a heart-breaking turn in the Apple TV+ series. Mark S convinces Ms. Casey to leave, which allows Gemma to take over once more. However, despite pleading with Mark S to join her in the stairwell, he hesitates just long enough for Helly R to find them.

We know Mark S loves Helly R, so we can see what's coming next. Mark S chooses Helly R over his outie's wife, and the pair flee through Lumon's labyrinthine halls as a devastated Gemma watches on through the exit door's tiny window.

Severance fans have long been conflicted about who they want Mark to end up with. The creative team's decision to have him pick Helly over Gemma is – for the time being at least – sure to generate a fierce debate between the loyal following of one of the best Apple TV+ shows'.

For her part, Lachman admitted she was sad when she learned that, after two years apart – not to mention Mark thinking his wife had been dead all that time – Mark and Gemma's reunion is a fleeting one. Nonetheless, as a fellow fan of the sci-fi mystery-thriller series, Lachman acknowledged how tough it must have been for Mark to make the decision.

"To see him again is just like a miracle for Gemma," Lachman told me. "I think she'd pretty much given up hope [of reuniting with Mark].

"I think it's such an incredible moment for them to turn into their innies [and] for Gemma to finally leave Lumon, and then see him, as Mark S instead of her husband, choose to walk away with another woman.

"But, she has a moment where she realizes 'Oh my god, it's not him [her husband],'" Lachman continued. "It's so intense and I feel like the audience, even as a fan myself, everyone is going to be torn [over Mark's decision] because there's this really wild love triangle happening now. You've got Helena and Mark, Helly and Mark S, and Gemma and Mark, so it's an incredibly complicated situation.

How does anyone want this to end? It's really difficult

Dichen Lachman, Severance actor

"You feel for Helly, and Mark S, and you really believe in that beautiful connection they have. At the same time, you have Gemma and Mark. How does anyone want this to end? It's really difficult. I mean, even as a viewer, I don't know how I want to end, because there's such beautiful things about both relationships."

When I suggested the possibility of a happy ending for all parties, Lachman added: "I don't know. What is a happy ending in this situation, right? Maybe they'll have to do a timeshare! That's my personal fan theory on how things could end."

Maybe that's a story thread you can take to creator Dan Erickson and executive producer Ben Stiller, Dichen? It's worth a try, especially with season 3 now officially confirmed to be in the works! For more news and exclusives on all things Severance, check out the section below.

As much as I love my Nintendo Switch and Steam Deck, I’m not convinced the handheld gaming console exercise has been nearly perfected from-wise since Nintendo’s Game Boy.

Sure the need for batteries and the chunky build of the original model wasn’t ideal, but later models made the cosine more pocketable. And the Game Boy Advance SP took it even further with a flippable design.

Foldable phones arguably make some headway giving a bigger screen for gaming but also a device that fits into a jacket pocket. But the software and gaming experience has yet to be perfected here. And for proper modern gaming power one needs a larger console.

So what’s the solution to this? Well, I think it might be a foldable console.

Sounds a bit odd doesn’t it? But my fellow managing editor and gaming fan, Josie Watson, got a look at a foldable console concept from Samsung Display. Check the video out below.

@techradar

I have to say I’m rather sold on this design. Usually, I’m skeptical about such concepts; last year we saw a flexible display that could be worn as almost a sci-fi-like smartwatch and I wasn’t convinced by it.

But a foldable console that takes a Switch-style design and helps make it more pocket-sized is pretty compelling.

Obviously, there would be concerns over cooling and how much performance could be extracted from such a device. Yet mobile tech has advanced enough to cleverly split chipsets into modules and use batteries that are separated but provide a single pool of power to tap into.

So I feel that there’s more scope for a foldable games console to become a practical reality.

What’s more, I reckon Microsoft could be the one to make it happen, given it’s partnered with Samsung before on the gaming side; I just don’t expect this to happen with the rumored Xbox handheld.

If nothing else, I’m still glad to see Samsung Display coming up with intriguing concepts, especially when the mainline company is increasingly treading the path of releasing iterative products, as seen with the Samsung Galaxy S25.

• Sirui joins the L-Mount Alliance along with Panasonic, Leica and more
• First Sirui L-Mount product will be an Aurora 85mm portrait lens
• More L-Mount lenses promised before end of 2025

The L-Mount Alliance just announced the addition of a new member – and it’s fantastic news for lovers of cheap, high-quality lenses.

Chinese lens manufacturer Sirui has become the latest company to sign up to the burgeoning technical and strategic partnership, which began in 2018 with founders Leica, Panasonic, Sigma and Ernst Leitz Wetzlar, adding DJI, Astrodesign, Samyang and Blackmagic Design to its ranks in the intervening years. In addition to dozens of lenses, there are currently around 20 L-Mount camera bodies on the market, including the Panasonic Lumix S1R II, Leica SL3, DJI Ronin 4D, Blackmagic Pyxis 6K and new Sigma BF.

Sirui’s membership means that it will now begin developing first-party lenses for the L-Mount system, starting with the Aurora 85mm f/1.4, a portrait prime with autofocus (a rarity for Sirui) and weighing just 504g.

The Sirui Aurora 85mm lens is already available for several mount systems – and L-Mount is next. (Image credit: Sirui) Affordable glass incoming

The Aurora is already available in Nikon Z, Sony E and Fujifilm X mount variants at an RRP of $499 / £456 / AU$763, which is exceedingly affordable for such a fast full-frame prime. And with most of Sirui’s lenses being relatively cheap, the company’s addition to the L-Mount Alliance looks like great news for thrifty L-Mount camera owners. In addition to still photography-focussed lenses like the Aurora, Sirui makes a wide line of cinema lenses, so L-Mount filmmakers may have some new high-quality glass available to them before too long.

Sirui disclosed the news about the imminent arrival of the L-Mount Aurora in a Facebook post, without confirming a release date. However, with the post also claiming that other Sirui autofocus lenses will join L-Mount before the end of 2025, it doesn’t sound like we’ll have too long to wait.

Now that Sirui is part of the L-mount Alliance, what L-mount versions of Sirui lenses do you hope to see? Let us know in the comments below
