AWS Reportedly Launching Newer, Faster Datacenter Chip

Amazon Web Services (AWS), retail giant's industry-leading cloud computing unit, has designed a new datacenter processor that will be at least 20 percent faster than its predecessor, sources told the Reuters news service last week.

The new processor will be based on Arm's Neoverse N1 micro-architecture and will integrate as many as 32 cores, Reuters reported. It's also expected to use fabric technology to connect with other chips and speed up tasks, such as image recognition.

The company's investment in a second Arm-based chip advances its custom silicon strategy and further reduces its reliance on Intel and AMD server chips.

AWS launched its first home-grown chip, called Graviton, last year at its AWS re:Invent conference in Las Vegas. The Graviton chips, which used Cortex-A72 micro-architecture, were created by Annapurna Labs, an Israel-based system-on-a-chip designer that AWS acquired in 2015. Annapurna also developed two generations of Nitro ASICs that run networking and storage tasks in AWS datacenters. A1 instances were the first EC2 instances powered by the Graviton chips.

There has been no official announcement of the new, as-yet-unnamed AWS processor, and AWS is keeping the release date under wraps. The company did not respond to our requests for comment at press time.

British chip designer Arm Holdings was acquired in 2016 by Japanese multinational telecom corporation Softbank Group. Since then, Arm, which is well-established in the mobile and embedded device markets, has become a serious contender in the datacenter server space -- in no small part because of its "de-verticalized" ecosystem, AWS Vice President James Hamilton observed in a blog post on the Graviton release last year.

"Arm does the processor design, but they license the processor to companies that integrate the design in their silicon, rather than actually producing the processor themselves," he wrote. "This enables a diverse set of silicon producers, including Amazon, to innovate and specialize chips for different purposes, while taking advantage of the extensive Arm software and tooling ecosystem."

The result of this model, he added, is "innovation and competition at every layer of the Arm ecosystem from design, through silicon foundry, packaging, board manufacturing, all the way through to finished hardware systems and the system software that runs on top."
