Leaked AMD Zen 4 Epyc Genoa CPU benchmarks: AVX512 performance similar to Intel’s next-gen Sapphire Rapids, strong multi-core scores [Leak]


Early benchmarks of the 4th Gen AMD Epyc Genoa processors have surfaced indicating strong AVX512 performance, a first for the Zen family. The leak in question consists of two 96-core SKU in a 2S configuration for a total of 192 cores, making it the densest to date. In addition to impressive multi-threading capabilities, the chip has registered outstanding AVX512 performance as seen in the CPU-Z AVX-512 test.

In the AVX512 single-thread benchmark, the Zen 4-based Epyc Genoa part performs in roughly the same league as the Intel Xeon (Golden Cove) Sapphire Rapids-SP parts. We watch 627 points for the Zen 4 (2.15 to 3.5 GHz) against 628 for the Golden Cove (1.9 to 3.7 GHz) core. In the multi-threaded AVX512 test, the former scores 15,625 points, more than any other Sapphire Rapids chip on the list.

Moving on to standard multi-core benchmarks, the Zen 4 Epyc part trades blows with Sapphire Rapids-SP in R15 and R20 despite only having 128 cores enabled. In the latest iteration of Cinebench, the Zen 4-based Epyc Genoa eats all of the Sapphire Rapids for breakfast. Even with just 128 cores, it still manages to beat the higher-frequency Intel Xeon by over 40%. Similar performance can be seen in multi-core V-Ray where Genoa again beats everything else on the table.

Ultimately, however, it’s important to note that server workloads are customer-specific, and an architecture beneficial for one may not be suitable for another. From a raw performance perspective, Zen 4 looks solid for PCs and data centers.
