U7inh instance has 1,920 virtual CPUs and 32TB of memory, and you can run 4 of these
Need to sustain SAP workloads is what encouraged HPE to work with AWS
However, there's also the fact HPE may be helping AWS get newer, lucrative leads
As businesses face relentless data growth, challenges like data silos and outdated legacy systems, such as Unix-based servers, increasingly stand in the way of progress.
HPE has positioned its Compute Scale-up Server 3200, which it launched in 2023, as the answer to these challenges, promising scalability and performance for mission-critical applications.
The server supports workloads like SAP HANA and ERP with up to 16 sockets and 32TB of shared memory, enabling seamless scalability and reduced server sprawl. Powered by 4th Gen Intel Xeon Scalable processors (Sapphire Rapids), it doubles core counts, integrates AI accelerators, and features DDR5 memory with PCIe 5.0 for enhanced performance and bandwidth, ideal for data-intensive applications.
Eroding on-premises market share?
AWS has now announced the general availability of a new Amazon Elastic Compute Cloud (Amazon EC2) U7inh-32tb.480xlarge instance which runs on the 16-socket HPE Compute Scale-up Server 3200 and is built on the AWS Nitro System.
While that sounds like a positive move for HPE customers, it does raise concerns about the strategic implications.
AWS’s new U7inh instance features 1,920 vCPUs, 32TB of DDR5 memory, 160 Gbps of EBS bandwidth, and 200 Gbps of network bandwidth. AWS says, “You can run your largest in-memory database workloads like SAP HANA or seamlessly migrate workloads running on HPE hardware to AWS.”
As The Register notes, however, AWS’s announcement of the new offering mentions "customers that currently run on-premises with HPE servers have also asked how we can help them migrate to AWS to take advantage of cloud benefits while continuing to use HPE hardware."
By partnering with AWS, HPE potentially opens the door for the cloud giant to gain access to customers running critical workloads on-premises who may be considering cloud migration.
This partnership could inadvertently help AWS capture more enterprise leads, potentially eroding HPE’s on-premises market share. The timing is particularly striking, as AWS has acknowledged a growing trend of customers revisiting on-prem solutions.
New year's resolutions are just the kind of chore you don't need after a week of relaxing excess – so this year we're committing to 'tech resolutions' instead.
These friendlier, less intimidating commitments involve using gadgets or apps to nudge your life in the right direction. Or they can simply help you survive the brutal month that is January. Best of all, they all involve tech.
The tech resolutions below don't involve giving up indulgences or hitting gyms. Instead, they're a mix of ideas from the TechRadar team on how they'll be using gadgets, apps or a mix of the two to try new hobbies, save money or just have a blast with new board game discoveries in early 2025.
There are guides on how to slash your streaming bills, set up your iPhone 16 to take better photos in 2025, and use Notion to plan your new year. But there are also fun side quests, like how to rediscover the joy of CDs and one writer's advice on the best cheap gadgets to raise your bread-making game.
Whichever part of your tech life needs a shot of new year's enthusiasm, you'll find some valuable nuggets of advice below. And if it inevitably all goes wrong, you can always blame the gadgets...

Our streaming bills have quickly become bigger than Elon Musk's ego – it's time to take action. TechRadar contributor Esat Dedezade has broken down how he's embracing 'subscription hopping' in 2025 to save hundreds on his bills.
The tactic involves a little planning, but fortunately we've done all of that for you – including a 'cheat sheet' that shows all of the biggest shows landing on Netflix, Prime Video, Disney Plus and more in the first few months of 2025, so you can quickly create your own plan. Trust us, you'll feel extremely smug afterwards.
Owning an EV can be an expensive business, not least because of pesky depreciation. But whether you've bought new or second-hand, there is one thing you can control – charging costs.
TechRadar's EV expert Leon Poultney, who spends roughly 72% of his life on the road in electric cars, has broken down all of his top tips for saving cash on EV charging in 2025. And no, it doesn't involve buying a solar farm.
YouTube Premium has so many hidden benefits that it may well be the best-value streaming subscription out there. That's the compelling argument made by TechRadar contributor David Nield, who describes why it's the only digital subscription he's keeping for the whole of 2025.
As he describes, YouTube Premium isn't just about getting respite from ads (although that is one major benefit). It also brings a host of bonus, like YouTube Music – which could convince you to ditch a separate music streaming service.

Our PS5 Pro review was enough to convince TechRadar contributor Darren Allan to skip the console and make a different gaming plan for 2025 – and it involves cables.
That's because this particular Plan B is built around hooking up a gaming PC in another room to a living room TV. A not inconsiderable task, but one that means saving lots of cash on a PS5 Pro – and ultimately creating a better gaming setup.
Do you have a tower of dusty CDs at home that audibly grumble every time you open Spotify? So does TechRadar contributor and CD hoarder Tom Wiggins, but he has a plan to put that right in 2025.
The Fiio DM13, a modern Discman tribute act, is the key to this particular tech resolution. And it means riding the mid-90s comeback and living like it's the height of Britpop, with even better sound quality.
Looking to take better photos with your iPhone in 2025? This guide from TechRadar's former cameras editor will help set you up.
While it's mainly focused on the iPhone 16 and 16 Pro (including their new Camera Control button), a lot of the tips also apply to older iPhones that are running iOS 18.
It's now possible to get the experience and results of a traditional compact camera from your iPhone – here's how to do it.
Yes, it's finally time – Windows 11 might be a magnet for online criticism (justifiably so, in many cases), but TechRadar computing writer Darren Allan explains why he's going to be upgrading to Microsoft's OS as the new year begins.
And no, it isn't just because the sands of time are running out for Windows 10 – there are also now positive reasons to upgrade, including some much-needed interface improvements.
I used to own a lot of CDs. And by “a lot”, I mean a lot. Since I was a teenager in the late ‘90s a significant chunk of my disposable income went on music, but when Spotify launched in 2009 that began to slow down, until on July 29 2016 I ordered my final CD from Amazon (Drive Like Jehu’s self-titled album, if you’re interested).
I’ve been pretty much streaming-only ever since, and while I’ve purged a lot of CDs in recent years (mainly the albums I couldn't name a single song from without looking at the track-listing) there are a couple of hundred I can’t bring myself to get rid of.
Without a means to play any of them – I’d streamlined my hi-fi setup to include just a pair of Ruark MR1 Mk 2 speakers and an iFi Uno DAC connected to my disc-less MacBook Air when I moved out of London a few years ago – that seemed stupid.
But I spent a good chunk of my young adult life accumulating these shiny silver discs, some of which were acquired at gigs by obscure math-rock bands of the mid-2000s and certainly won’t be found on Spotify or Apple Music.
Even if they do now live in boxes under the stairs, existing as little more than a back-up archive to a hard drive full of ripped MP3s, they’re still part of my identity. And then one day the perfect solution dropped into my inbox.
What's in a name?

Try to buy a small, affordable CD player these days and you’ll mainly find cheap, plastic all-in-one systems made by companies called things like Pjlopj, Lvcdodvd and Gelielim (I actually made one of those up but I bet you don’t know which one).
Why was I choosing to listen to audibly inferior versions of stuff I’d spent so much time and money collecting?
In all honesty, the name FiiO isn’t much better, but the company at least has some recent pedigree when it comes to making hi-fi gear, with a number of its products earning five-star reviews right here on TechRadar. So news of its new $139 / £139 (around AU$275) DM13 CD player was music to my ears.
Here was a battery-powered CD player that’s barely any bigger than an old Sony Discman – not quite pocket-sized, but small enough to stash in a drawer when not in use – that has Bluetooth onboard so you can connect a pair of headphones, load up a copy of OK Computer and hit the streets like it’s 1997 all over again.
Mine arrived in the post just before Christmas, and its brushed metal chassis makes it vaguely reminiscent of Apple’s old Superdrive (RIP), particularly if you opt for the silver version. It can even convert CDs into MP3s if you hook it up to a computer.
I attempted to pair it with my Ruarks over Bluetooth but with its limited single-line display and very basic instruction manual, getting the two to talk to each other was like trying to change the clock on a microwave using only morse code.
Fortunately, it has standard aux and optical outputs as well, so I just dug out my box of miscellaneous cables (we’ve all got one) and went wired instead. I had created the perfect hi-fi setup for a millennial with limited space.

Top tips for CD revivalists
1. Check Ebay for CD bargains A copy of Oasis’s debut album Definitely Maybe will set you back the best part of $35 / £30 on vinyl, but resellers such as Music Magpie (or Discogs in the US) have eBay shops where you can pick up a CD copy for far less. Try your local charity shops, too.
2. Only buy stuff you really love If you start buying everything on CD you’ll quickly end up with a collection that’s hard to manage and you’ll be forced to purge some of it. Spotify and the other streaming services are the perfect tool for quality control, allowing you to try before you buy.
3. Keep your CDs out of the sun My CD collection spent over a decade of its life by a window where it would catch the evening sun. As a result a good chunk has severely faded spines and partially bleached back covers, which bothers me from a sentimental perspective rather than a resale one. Try to look after yours better.
It’s not just because I’m a hoarder who can’t let go of the past that I’m planning to spend 2025 like it’s the height of Britpop all over again (and the Oasis reunion has nothing to do with it either).
Spotify’s refusal to increase its streaming quality has been bothering me for some time, but it was only when I was listening to some of those old MP3s that I realised just how noticeable it is. Why was I choosing to listen to audibly inferior versions of stuff I’d spent so much time and money collecting?
I also rarely listen to a full album from start to finish anymore, so rather than just switching to a different digital format I figured a CD player would be the perfect way to reconnect with music all over again.
I’m not the only one who’s plotting a physical-media renaissance. Sales of CDs rose 2% in 2023 and were up again 3.2% in the first half of 2024. That small upward trend is partially down to younger generations developing an interest in owning tangible formats but not having the disposable income to spend on vinyl (apparently it all goes on snozzberry vapes).
I get that. I bought a lot of my CDs for £7 or less in shops like Fopp or Rounder Records (another RIP) in Brighton, UK and the thought of spending over £20 on just one album back then would’ve horrified me. What if it was rubbish? (Which, considering a proportion of it was mid-noughties math-rock, was fairly likely.)
With people like me offloading hordes of old CDs there are bargains to be found – and while the format isn’t as indestructible as was once claimed, the discs are often in decent nick, even if the cases and liner notes aren’t.
You can connect a pair of headphones, load up a copy of OK Computer and hit the streets like it’s 1997 all over again.
I probably won’t ditch Spotify completely. As portable as the FiiO DM13 is – connecting a pair of Bluetooth headphones presented fewer issues and it does have skip protection – my pockets are only big enough for my iPhone 16 Pro. Streaming is also unbeatable when it comes to discovering new stuff, plus I don’t have space to add significantly to my existing CD collection. My bank balance wouldn’t thank me either.
But the contents of those boxes under the stairs is going to get a chance to shine again in 2025 – and it’s all down to another little black box with a silly name.
But AWS is also part of Amazon, which owns Amazon Prime Video, a huge rival to Netflix
Netflix engineers have been struggling to keep track of how much resources they use on AWS
Netflix, the world’s most popular streaming platform, may dominate home entertainment, but it’s struggling to manage one of its biggest operational challenges: cloud computing costs.
Despite its tech-forward image, Netflix has admitted it doesn’t fully know how much it spends on the cloud, an oversight made even more surprising given that its cloud provider, AWS, is part of Amazon - owner of Prime Video, one of Netflix’s largest competitors.
Relying on AWS for compute, storage, and networking, Netflix’s cloud infrastructure supports its global streaming service. Engineering teams use self-service tools to create and deploy applications, generating vast amounts of data. However, the complexity of this ecosystem makes it difficult for Netflix to understand exactly how resources are used and how costs accumulate.
Keeping its content flowing
The Platform Data Science Engineering (DSE) team at Netflix has taken on the task of untangling this problem. The team’s mission is to help the company’s engineers understand resource usage, efficiency, and associated costs.
Yet, as Netflix acknowledged in a recent blog post, its cloud cost management is still a work in progress.
To address the challenges it finds itself facing, Netflix has developed two tools: Foundational Platform Data (FPD) and Cloud Efficiency Analytics (CEA). FPD provides a centralized data layer with a standardized model, aggregating data from applications like Apache Spark. CEA builds on this by applying business logic to generate cost and ownership attribution, providing insights into efficiency and usage patterns.
The hurdles are significant. Netflix’s sprawling infrastructure includes services with multiple owners, varying cost heuristics, and multi-tenant platforms that complicate tracking.
Data delays and platform-specific customizations add a further layer of complexity. Regular audits and data transformations are necessary to maintain accuracy, but the company admits it has yet to achieve full visibility into its cloud spending.
Looking ahead, Netflix says it plans to expand its tools and incorporate predictive analytics and machine learning to optimize usage and detect cost anomalies.
While the company works to refine its approach, its situation highlights a striking irony: the world’s most popular streaming platform relies on its rival’s technology to deliver its own service, yet it is still figuring out the true cost of keeping its content flowing.
Trillium has hit general availability just months after preview release
Powerful AI chip offers more than four times the training performance
Google uses it to train Gemini 2.0, the company's advanced AI model
Google has been developing Tensor Processing Units (TPUs), its custom AI accelerators, for over a decade, and a few months after being made available in preview, has announced that its sixth-generation TPU has reached general availability and is now available for rent.
Trillium doubles both the HBM capacity and the Interchip Interconnect bandwidth, and was was used to train Gemini 2.0, the tech giant’s flagship AI model.
Google reports it offers up to a 2.5x improvement in training performance per dollar compared to prior TPU generations, making it an appealing option for enterprises seeking efficient AI infrastructure.
Google Cloud’s AI Hypercomputer
Trillium delivers a range of other improvements over its predecessor, including more than four times the training performance. Energy efficiency has been increased by 67%, while peak compute performance per chip has risen by a factor of 4.7.
Trillium naturally improves inference performance as well. Google’s tests indicate over three times higher throughput for image generation models such as Stable Diffusion XL and nearly twice the throughput for large language models compared to earlier TPU generations.
The chip is also optimized for embedding-intensive models, with its third-generation SparseCore providing better performance for dynamic and data-dependent operations.
Trillium TPU also forms the foundation of Google Cloud’s AI Hypercomputer. This system features over 100,000 Trillium chips connected via a Jupiter network fabric delivering 13 Petabits/sec of bandwidth. It integrates optimized hardware, open software, and popular machine learning frameworks, including JAX, PyTorch, and TensorFlow.
With Trillium now generally available, Google Cloud customers have the opportunity to access the same hardware used to train Gemini 2.0, making high-performance AI infrastructure more accessible for a wide range of applications.
Project Infinity and Mobile Security Rewards Program bolster Samsung's security strategy
Red, Blue, and Purple teams safeguard Galaxy devices from cyber threats
CTI task force scours the Dark Web to prevent device breaches
Samsung has always prioritized security for its Galaxy smartphones, and with the launch of the Galaxy S24 series, it promised an unprecedented seven years of mobile security updates.
Behind this extended protection lies a secretive and highly specialized security initiative known as Project Infinity - but Samsung has now lifted the veil and provided some details about the project.
Project Infinity comprises multiple task forces which ensure that the billions of Galaxy smartphone users worldwide are protected from the ever-growing threat of cybercrime.
The invisible guardians of Galaxy devices
At the core of Project Infinity are three distinct teams, Red, Blue, and Purple, alongside a Cyber Threat Intelligence (CTI) taskforce. These groups operate globally in countries such as Vietnam, Poland, and Brazil, working in the shadows to prevent and mitigate cyberattacks.
Each team has a specific role, from proactive threat detection to creating and deploying defensive measures. Their work is largely invisible to the public, only surfacing when you receive a security patch on your device.
The CTI task force specializes in identifying potential cyber threats, ensuring that hackers can’t exploit vulnerabilities in Galaxy devices. The team scours the Deep Web and Dark Web, looking for signs of illicit activity, from malware to stolen data.
By analyzing system behaviors, such as unusual data requests or suspicious network traffic, the team can identify and neutralize threats, while collaborating with other departments to roll out security updates.
“Occasionally, we engage in security research by simulating real-world transactions," noted Justin Choi, Vice President and Head of the Security Team, Mobile eXperience Business at Samsung Electronics.
"We closely monitor forums and marketplaces for mentions of zero-day or N-day exploits targeting Galaxy devices, as well as any leaked intelligence that could potentially serve as an entry point for system infiltration.”
Samsung’s security operation is modeled on military-style tactics, with the Red and Blue teams simulating attacks and defenses, respectively.
Through techniques like "fuzzing," which involves throwing random data at software, they can find hidden vulnerabilities that might otherwise go unnoticed. Meanwhile, the Blue team works tirelessly to develop and implement patches that protect against these vulnerabilities.
The Purple team combines the expertise of both Red and Blue teams, focusing on critical areas of Galaxy’s security infrastructure. They also work with external security researchers to ensure no potential weak spot goes unnoticed.
HBM4 chips poised to power Tesla's advanced AI ambitions
Dojo supercomputer to integrate Tesla’s high-performance HBM4 chips
Samsung and SK Hynix compete for Tesla's AI memory chip orders
As the high-bandwidth memory (HBM) market continues to grow, projected to reach $33 billion by 2027, the competition between Samsung and SK Hynix intensifies.
Tesla is fanning the flames as it has reportedly reached out to both Samsung and SK Hynix, two of South Korea's largest memory chipmakers, seeking samples of its next-generation HBM4 chips.
Now, a report from the Korean Economic Daily claims Tesla plans to evaluate these samples for potential integration into its custom-built Dojo supercomputer, a critical system designed to power the company’s AI ambitions, including its self-driving vehicle technology.
Tesla’s ambitious AI and HBM4 plans
The Dojo supercomputer, driven by Tesla’s proprietary D1 AI chip, helps train the neural networks required for its Full Self-Driving (FSD) feature. This latest request suggests that Tesla is gearing up to replace older HBM2e chips with the more advanced HBM4, which offers significant improvements in speed, power efficiency, and overall performance. The company is also expected to incorporate HBM4 chips into its AI data centers and future self-driving cars.
Samsung and SK Hynix, long-time rivals in the memory chip market, are both preparing prototypes of HBM4 chips for Tesla. These companies are also aggressively developing customized HBM4 solutions for major U.S. tech companies like Microsoft, Meta, and Google.
According to industry sources, SK Hynix remains the current leader in the high-bandwidth memory (HBM) market, supplying HBM3e chips to NVIDIA and holding a significant market share. However, Samsung is quickly closing the gap, forming partnerships with companies like Taiwan Semiconductor Manufacturing Company (TSMC) to produce key components for its HBM4 chips.
SK Hynix seems to have made progress with its HBM4 chip. The company claims that its solution delivers 1.4 times the bandwidth of HBM3e while consuming 30% less power. With a bandwidth expected to exceed 1.65 terabytes per second (TB/s) and reduced power consumption, the HBM4 chips offer the performance and efficiency needed to train massive AI models using Tesla’s Dojo supercomputer.
The new HBM4 chips are also expected to feature a logic die at the base of the chip stack, which functions as the control unit for memory dies. This logic die design allows for faster data processing and better energy efficiency, making HBM4 an ideal fit for Tesla’s AI-driven applications.
Both companies are expected to accelerate their HBM4 development timelines, with SK Hynix aiming to deliver the chips to customers in late 2025. Samsung, on the other hand, is pushing its production plans with its advanced 4-nanometer (nm) foundry process, which could help it secure a competitive edge in the global HBM market.
Broadcom is rumored to have an ongoing partnership with Apple to help it build its own AI chip
TikTok parent company, ByteDance, OpenAI also reportedly in the picture
The move comes as hyperscalers look to reduce their dependency on AI chips from Nvidia
Nvidia has ridden the generative AI boom to record-breaking revenues and profits over the past two years, and while it remains well ahead of its competitors, the company is facing growing pressure - not only from rival AMD but also from hyperscalers which have traditionally relied on Nvidia GPUs but are now looking to reduce their dependence on its hardware.
As The Next Platform notes, “Nvidia’s biggest problem is that its biggest customers have massive enough IT expenditures that they can afford to compete with Nvidia and AMD and design their own XPUs for serial and parallel computing. And when they do so, it is chip design and manufacturing houses Broadcom and Marvell, who have vast expertise running chippery through the foundries of Taiwan Semiconductor Manufacturing Co, who will be benefiting.”
In its most recent earnings conference call, Hock Tan, President and CEO of Broadcom, told investors, “Specific hyperscalers have begun their respective journeys to develop their own custom AI accelerators or XPUs, as well as network these XPUs with open and scalable Ethernet connectivity. As you know, we currently have three hyper-scale customers who have developed their own multi-generational AI XPU roadmap to be deployed at varying rates over the next three years. In 2027, we believe each of them plans to deploy one million XPU clusters across a single fabric.”
Gaining its fair share
Without naming specific companies, Tan added, “To compound this, we have been selected by two additional hyperscalers and are in advanced development for their own next-generation AI XPUs.”
It is widely believed that Broadcom is working with Google and Meta, and as we previously reported, with ByteDance and OpenAI on custom AI chips.
Apple is also thought to be developing its first artificial intelligence server chip, codenamed “Baltra,” with Broadcom providing the advanced networking technologies essential for AI processing.
During the Q&A portion of the earnings call, when Tan was asked about market share, he responded, “All we are going to do is gain our fair share. We're just very well positioned today, having the best technology, very relevant in this space. We have, by far, one of the best combination technologies out there to do XPUs and to connect those XPUs. The silicon technology that enables it, we have it here in Broadcom by the boatloads, which is why we are very well positioned with these three customers of ours.”
Castrol planning fluid-as-a-service model launch to eliminate waste and increase sustainability
Immersion cooling has emerged as an essential component in the race to reach AGI
Castrol wants to play a key role in immersion cooling as integrated smart city data centers become mainstream
Founded in 1899, CC Wakefield & Co. Limited initially focused on producing lubricants for trains and heavy machinery. Over time, the company expanded its expertise to develop specialized lubricants for automobiles and airplane engines, incorporating castor oil - a plant-based oil derived from castor beans - to ensure performance under extreme temperature conditions. The product was called Castrol, and the company was later renamed after its famous creation.
125 years later, Castrol remains at the forefront of innovation, applying its extensive expertise in fluid engineering to address modern challenges.
One of its key focus areas is the development of advanced dielectric fluids for immersion cooling systems. This approach sees entire servers submerged in non-conductive fluids that absorb and transfer heat away from the components, eliminating the need for traditional fans.
Advanced thermal management
The Castrol ON Liquid Cooling Centre of Excellence in Pangbourne, UK, serves as a state-of-the-art research and development hub for liquid cooling technologies.
The facility develops customized solutions and rigorously tests fluid dynamics, material compatibility, and server performance, to address the challenges of traditional cooling methods.
In a recent visit, StorageReview had the opportunity to see Castrol’s cutting-edge immersion tanks from providers like GRC and Submer and was impressed by the adaptability and efficiency of the solutions.
Writer Jordan Ranous noted, “In one of the test cells, we observed GRC’s tank, which had a striking green glow due to the specific fluid Castrol was using. The servers submerged in this tank were undergoing compatibility and performance testing. Castrol ensures that every component, from CPUs to cables, can operate effectively in immersion cooling environments without degradation.”
Castrol’s ON range of single-phase dielectric fluids, including DC15 and DC20, aims to deliver advanced thermal management, durability, and safety while maintaining efficient performance at operating temperatures between 40°C and 50°C, with some systems capable of handling up to 70°C.
Chris Lockett, VP of Electrification and Castrol Product Innovation at BP, Castrol’s parent company, told StorageReview, “At the moment, about 40% of power consumption in data centers goes toward cooling. Immersion cooling can drop that figure to less than 5%, significantly lowering power and water usage.”
Data centers account for an estimated 2–3% of global power consumption, with current liquid cooling efforts primarily focused on direct-to-chip solutions. Immersion cooling has the potential to establish a new standard for thermal management and Castrol wants to lead this transformation, positioning itself as “a one-stop partner for the liquid cooling solutions of today and tomorrow.”
