At AMD’s Advancing AI event this week, the company revealed more details of its upcoming MI455X GPU and the Helios rack-scale architecture that will join 72 of those GPUs into a coherent accelerator—the largest such system that AMD has built so far and its first to truly compete with Nvidia’s NVL72 rack-scale design, as used in the Blackwell and Rubin generations.
AMD calls the MI455X “by leaps and bounds the most advanced AI accelerator we’ve ever built,” and from what we’ve seen, it’s the most competitive product at both the chip level and at rack scale that AMD has ever put up against Nvidia’s thorough dominance of the AI compute race.
