Plucky CPU maker beats AMD and Intel to become first to offer 320 cores per server — with even bigger models in the pipeline

Oracle has snubbed leading CPUs from the likes of AMD and Intel in favor of AmpereOne processors for use in its Oracle Cloud Infrastructure (OCI) A2 Instances – offering the highest core count in the industry.

Coming in 2024, the new OCI service – which has 320 cores in the bare metal shape and 156 cores in the flexible virtual machine (VM) shape – will be used to power general-purpose cloud workloads. These include running web servers, transcoding video, and servicing CPU-based AI inference workloads.

At the same time, Oracle also announced two additional new services including OCI compute bare metal instances, powered by Nvidia H100 GPUs, as well as OCI compute bare metal instances powered by Nvidia L40S GPUs.

A major coup for Ampere

“Oracle was the first cloud services provider to globally deploy compute instances based on Ampere processors,” said Jeff Wittich, chief product officer at Ampere Computing. “This new generation of Ampere A2-based instances from Oracle Cloud Infrastructure will provide up to an industry-leading 320 cores per instance for even better performance, workload density, and scale.”

Having such a high core count can support higher performance as well as VM density – and can scale better to support customers’ needs, according to Oracle. They can also run in flexible shapes for VMs to provide them with maximized resources and minimized costs. 

Oracle has purchased $4.7 million worth of processors from Ampere, according to Serve the Home, in addition to a $104.1 million prepayment for future CPUs, which represents a major win for the company. 

The super-dense chip was released in May 2023 and has a maxmum of 192 cores squeezed into a single chiplet. The dual-socket Arm-based AmpereOne CPUs Oracle is purchasing offer 2MB/core, 8 channel DDR5, 128 Lanes PCIe Gen5, and power consumption falls between 200W and 350W.

This news follows very shortly after the same publication reported Google Cloud had agreed to use Ampere AmpereOne CPUs in its C3A compute instances in August. 

Although providers including Microsoft have been using Ampere Altra chips previously, Google and Oracle have been the first to incorporate its higher-end line of CPUs into high-performance cloud computing infrastructure.

TechRadar's Year in Review: AI revolution, smartphone evolution, and visions of the future

If I had to sum up 2023 in one word it would be AI. Okay, technically that’s two initials, but let’s not quibble – because there’s no doubt that it provided the year in tech with its main story arc. Artificial intelligence was everywhere this year, as every company in the world gawped at the massive impact of ChatGPT, and decided they wanted to jump aboard that bandwagon. You could barely move for new chatbots, new image generators, and new AI-enhanced features in every device released in 2023. And there’s no sign of that changing in 2024; in fact, we expect it to be an even bigger deal. Elsewhere, phones and laptops did much the same as they had the previous year – well, except where they had new AI-enhanced features – so it was in the virtual reality space where bigger changes were afoot. If the Meta Quest 3 was impressive then the Apple Vision Pro looks to be genuinely game-changing, and we can’t wait to see what impact it has in the next 12 months. Of course we also saw plenty ...

Microsoft and Sony enter "binding agreement" to keep Call of Duty on PlayStation

Microsoft has announced that it has reached a "binding agreement" with Sony, pledging to keep Call of Duty on PlayStation following the acquisition of Activision Blizzard.  With Microsoft having won its anti-trust case with the US Federal Trade Commission , its planned acquisition of Call of Duty developers Activision Blizzard has taken a big step closer to becoming a reality. In order to alleviate the concerns of monopoly-building that got Microsoft in legal hot water to begin with, the head of Xbox, Phil Spencer, announced yesterday via Tweet that it has entered into an "agreement to keep Call of Duty on PlayStation."  This agreement will no doubt come as a relief to fans concerned that Microsoft's acquisition plans might result in Call of Duty becoming an Xbox exclusive, following in the footsteps of future Bethesda releases. Since Microsoft's acquisition of Bethesda caused the studio to break its tradition of offering titles cross-platform for upcomi...

This Stardew Valley-like farming sim plays at the bottom of your screen so you work and play at the same time

Stardew Valley and Animal Crossing are among some of the best choices out there if you're looking for a game to get swept up in for hours at a time. But, if you're a fan of management sims and a multitasker as well, this upcoming farming sim will likely pique your interest.  Developed by Mister Morris Games, Rusty's Retirement is an idle-farming simulation game that runs at the bottom of your gaming monitor, allowing you to focus on other tasks like working while you tend to your crops. Set to release in Q1 2024 on Steam , the idle sim puts you in the shoes of a wholesome robot as you grow crops and use them to produce clean and energy-efficient biofuel. Having gathered this "vital robot power source," you'll then need to sell your harvest to the other machine inhabitants of your settlement. This, in turn, will let you reinvest the money into expanding your farm. If you're a terrible procrastinator (like me) this might not sound like your cup of tea...
