Things to sit up for: During the final Financial Analyst Day in June 2022, AMD introduced that its Zen 5 processors are scheduled to debut in 2024. While the corporate has but to launch any official Zen 5 benchmarks, we now have an unofficial prediction about its efficiency and different metrics from a widely known insider.
Jim Keller, who led the event of AMD’s Zen CPU structure, revealed some necessary information concerning the firm’s Zen 5 processors, that are anticipated to launch subsequent yr. The revelations, which had been introduced throughout a college pupil keynote in Bangalore, India, included particulars on efficiency, clock speeds, and energy estimates for AMD’s upcoming product line.
Keller, now CEO of AI {hardware} firm Tenstorrent, talked concerning the firm’s Ascalon processor core and confirmed comparative efficiency information for a variety of knowledge middle CPUs, together with Intel’s Sapphire Rapids, Amazon’s Graviton 3 and Nvidia’s Grace processing machine, and Zen 5 .
Keller claims that Ascalon will ship market-leading integer efficiency per watt, and predicts that Zen 5 will likely be 30 p.c sooner than Zen 4 for integer workloads. If the outcomes are correct, this might be a powerful replace, as Zen 4 already affords a 15% enchancment over Zen 3.
In phrases of clock speeds, Keller stated he expects Zen 5 server chips to hit the 4 GHz mark, which may make them the primary chips of their variety to achieve these speeds, relying on Intel’s launch of its Emerald Rapids lineup later this yr. processing. By comparability, the EPYC Genoa and Sapphire Rapids processors solely hit 3.7 GHz and three.8 GHz, respectively.
Finally, due to the 4nm/3nm course of nodes, Zen 5 chips are anticipated to be considerably extra energy environment friendly than their predecessors, regardless of elevated frequency and efficiency. Keller’s information additionally means that Zen 5 would be the quickest enterprise next-gen providing, scoring 8.84 on the SPEC CPU 2017 INT Rate benchmark. In comparability, Sapphire Rapids is anticipated to attain a 7.45, Grace can obtain a 7.44, and Zen 4 can solely obtain a 6.80.
It’s value noting right here that Zen 5 efficiency figures, frequencies, and energy estimates are Keller’s predictions, not real-life benchmarks and even leaked specs. So take them with a grain of salt as they’re unlikely to be fully correct.
