AMD Zen5 allegedly tested with Cinebench R23
AMD Zen5 architecture debut is not expected anytime soon, but early engineering samples are apparently already running in the labs. Moore’s Law is Dead claims to have a screenshot featuring a Zen5 pre-release hardware running a popular benchmark.
The CPU that was alleged tested is a dual socket 64 core Zen5 EPYC processor. The system shows 128 cores and 256 threads, which was apparently enough to score 123K points in Cinebench R23 multi-core test. This is around 15% higher than the Genoa (Zen4) CPU that was recently tested and almost at the same level as overclocked Sapphire Rapids HEDT CPUs from Intel using Liquid Nitrogen:
The Zen5 engineering sample was running with a clock up to 3.85 GHz, however it remains to be confirmed whether that’s a peak boost speed for this sample or something close to average. Furthermore, the screenshot from Windows Task Manager shows L1 cache at 10 MB, so 80 KB per core (Zen4 is 64 KB).
It would also appear that this sample had 8 CCDs, so each chiplet would again have 8 cores. Furthermore, it is mentioned that a variant of Zen5 CPU called Turin-Dense would have 16 cores per chiplet.
AMD EPYC Zen5 is expected to launch next year. It should be a completely redesigned architecture with a new pipeline and integrated AI optimizations. The Zen5 for consumers should deploy on the same AM5 socket that is currently used by 600-series motherboards. The same support is expected from the EPYC SP5 platform.
