Google Says Its AI Supercomputer Is Faster, Greener Than Nvidia A100 Chip

Alphabet Inc’s Google launched on Tuesday new particulars concerning the supercomputers it makes use of to coach its synthetic intelligence fashions, saying the methods are each quicker and extra power-efficient than comparable methods from Nvidia Corp.

Google has designed its personal {custom} chip known as the Tensor Processing Unit, or TPU. It makes use of these chips for greater than 90% of the corporate’s work on synthetic intelligence coaching, the method of feeding information by fashions to make them helpful at duties comparable to responding to queries with human-like textual content or producing photographs.

The Google TPU is now in its fourth technology. Google on Tuesday printed a scientific paper detailing the way it has strung greater than 4,000 of the chips collectively right into a supercomputer utilizing its personal custom-developed optical switches to assist join particular person machines.

Improving these connections has develop into a key level of competitors amongst corporations that construct AI supercomputers as a result of so-called massive language fashions that energy applied sciences like Google’s Bard or OpenAI’s ChatGPT have exploded in measurement, which means they’re far too massive to retailer on a single chip.

The fashions should as an alternative be break up throughout 1000’s of chips, which should then work collectively for weeks or extra to coach the mannequin. Google’s PaLM mannequin – its largest publicly disclosed language mannequin to this point – was educated by splitting it throughout two of the 4,000-chip supercomputers over 50 days.

Google mentioned its supercomputers make it straightforward to reconfigure connections between chips on the fly, serving to keep away from issues and tweak for efficiency positive aspects.

”Circuit switching makes it straightforward to route round failed parts,” Google Fellow Norm Jouppi and Google Distinguished Engineer David Patterson wrote in a weblog submit concerning the system. ”This flexibility even permits us to vary the topology of the supercomputer interconnect to speed up the efficiency of an ML (machine studying) mannequin.”

While Google is simply now releasing particulars about its supercomputer, it has been on-line inside the corporate since 2020 in a knowledge heart in Mayes County, Oklahoma. Google mentioned that startup Midjourney used the system to coach its mannequin, which generates contemporary photographs after being fed just a few phrases of textual content.

In the paper, Google mentioned that for comparably sized methods, its chips are as much as 1.7 instances quicker and 1.9 instances extra power-efficient than a system based mostly on Nvidia’s A100 chip that was in the marketplace similtaneously the fourth-generation TPU.

A Nvidia spokesperson declined to remark.

Google mentioned it didn’t examine its fourth-generation to Nvidia’s present flagship H100 chip as a result of the H100 got here to the market after Google’s chip and is made with newer know-how.

Google hinted that it could be engaged on a brand new TPU that will compete with the Nvidia H100 however offered no particulars, with Jouppi telling Reuters that Google has ”a wholesome pipeline of future chips.”
