Alleged AMD Zen 5 Benchmarked In Dual EPYC ES CPU Configuration: 64 Cores Per Chip Up To 3.85 GHz, Faster Than 96-Core Genoa

wccftech.com:

The first and alleged performance benchmark of an AMD Zen 5 system running dual next-gen EPYC Turin CPUs has leaked out by Moore's Law is Dead.

According to Moore's Law is Dead, the rumor outlet has received what seems to be the first AMD Zen 5 CPU benchmarks. The benchmarks are not of a consumer-level Ryzen chip but of an EPYC dual-system configuration. The rumored chip could be part of the AMD EPYC Turin family which is expected to launch next year.

So before talking about benchmarks, we have to talk about the specs that this alleged chip boasts. First of all the CPU is a very early engineering sample so a lot can change between now and during the time of its launch. The AMD EPYC Turin ES CPU with Zen 5 core architecture features 64 cores and 128 threads and since this is a dual-socket configuration, it shows up as 128 cores and 256 threads. Each chip carries the same amount of L2 and L3 cache as the Zen 4 cores but the L1 cache sees a small upgrade.

The L1 cache goes from 64 KB on Zen 4 to 80 KB on Zen 4, marking a 25% increase. The L2 cache is 64 MB per chip (1 MB per core) and the L3 cache is 256 MB (4 MB per core). The CPU clocks seem to be rated at 2.3 GHz base & 3.85 GHz boost which might seem very high for an engineering sample of a CPU that releases more than a year from now. That's already 4% higher than the boost clocks of the AMD EPYC 9654 Genoa chip but during a recent projection slide, ex-AMD architect Jim Keller pointed out that Zen 5 might either hit or exceed the 4 GHz clock barrier on servers.

Now coming to the main action which is the performance benchmark, the dual AMD EPYC Turin system with Zen 5 CPUs was tested within Cinebench R23 and scored somewhere around 123K (~123,000) points. Compared to dual
