(Image credit: AMD) AMD has shared the first official benchmarks for its forthcoming EPYC 'Venice' CPUs , which will be the first chips to use the Zen 6 architecture. The flagship 256-core model hasn't been detailed in full, but AMD claims it offers 3.3 times the performance of the Nvidia Vera CPU in a rack-scale implementation with a fixed power budget of 100kW. Go deeper with TH Premium: CPU The constraints of this test completely change the framing of the results, so it's worth highlighting them first. AMD is looking at performance from the level of a rack, not an individual component on a single socket. AMD's results are modeled around a 100kW deployment, showing the performance across the rack rather than the performance on a single socket, or even a dual-socket system. AMD did not, however, actually test all of these deployments. There's a lot of modeling going on here, which AMD details in its methodology paper that was published alongside the results.…
