Microsoft has been creating a brand new synthetic intelligence (AI) chip, internally code-named Athena, since as early as 2019, in response to reporting from The Information at the moment. The corporate might make Athena extensively out there to be used throughout the firm itself and OpenAI as early as subsequent 12 months.

Consultants say Nvidia gained’t be threatened by these strikes — nevertheless it does sign the necessity for hyperscalers to develop their very own customized silicon.

AI chip growth in response to a GPU disaster

The chip, like these developed in-house by Google (TPU) and Amazon (Trainium and Inferentia processor architectures), is designed to deal with giant language mannequin (LLM) coaching. That’s important as a result of the size of superior generative AI fashions is rising quicker than compute capabilities wanted to coach them, Gartner analyst Chirag Dekate advised VentureBeat by electronic mail.

Nvidia is the market chief by a mile on the subject of supplying AI chips — with about 88% market share, in response to John Peddie Research. Corporations are vying simply to order entry to the high-end A100 and H100 GPUs that price tens of 1000’s of {dollars} every — inflicting what might be described as a GPU crisis.


Remodel 2023

Be part of us in San Francisco on July 11-12, the place high executives will share how they’ve built-in and optimized AI investments for fulfillment and averted widespread pitfalls.

“Modern generative AI fashions at the moment are utilizing a whole lot of billions of parameters requiring Exascale computational capabilities,” he defined. “With next-generation fashions ranging in trillions of parameters, it’s no shock that main expertise innovators are exploring numerous computational accelerators to speed up coaching whereas decreasing the time and value of coaching concerned.”

As Microsoft seeks to speed up its generative AI technique whereas chopping prices, it is sensible that they develop a differentiated customized AI accelerator technique, he added, which “might assist them ship disruptive economies of scale past what is feasible utilizing conventional commoditized expertise approaches.”

Customized AI chips deal with the necessity for inference velocity

The necessity for acceleration additionally applies, importantly, to AI chips that assist machine studying inference — that’s, when a mannequin is boiled all the way down to a set of weights that then use reside knowledge to provide actionable outcomes. Compute infrastructure is used for inference each time ChatGPT generates responses to pure language inputs, for instance.

Nvidia produces very highly effective, basic function AI chips and affords its parallel computing platform CUDA (and it derivatives) as a strategy to do ML coaching particularly, stated analyst Jack Gold, of J Gold Associates, in an electronic mail to VentureBeat. However inference typically requires much less efficiency, he defined, and the hyperscalers see a strategy to additionally impression the inference wants of their clients with personalized silicon.

“Inference in the end will probably be a a lot bigger market than ML, so it’s vital for the entire distributors to supply merchandise right here,” he stated.

Microsoft’s Athena not a lot of a menace to Nvidia

Gold stated he doesn’t see Microsoft’s Athena as a lot of a menace to Nvidia’s place in AI/ML, which has been dominant because the firm helped energy the deep studying “revolution” of a decade in the past; constructed a powerhouse platform strategy and software-focused strategy; and has seen its inventory rise in an period of GPU-heavy generative AI.

“As wants develop and variety of use expands as properly, it’s vital for Microsoft and the opposite hyperscalers to pursue their very own optimized variations of AI chips for their very own architectures and optimized algorithms (not CUDA particular),” he stated.

It’s about cloud working prices, he defined, but in addition about offering lower-cost choices for numerous clients who might not want/need the excessive price Nvidia choice. “I count on the entire hyperscalers to proceed to develop their very own silicon, not simply to compete with Nvidia, but in addition with Intel usually function cloud compute.”

Dekate additionally maintained that Nvidia reveals no indicators of slowing down. “Nvidia continues to be the first GPU expertise driving excessive scale generative AI growth and engineering,” he stated. “Enterprises ought to count on NVIDIA to proceed constructing on its leadership-class innovation and drive aggressive differentiation as customized AI ASICs emerge.”

However he identified that “innovation within the final section of Moore’s legislation will probably be pushed by heterogenous acceleration comprising GPUs, and application-specific customized chips.” This has implications for the broader semiconductor trade, he defined, particularly “expertise suppliers which have but to meaningfully interact in addressing the wants of the quickly evolving AI market.”
