The first benchmarks of AMD’s 4th Gen Epyc Genoa processors have surfaced, indicating strong AVX512 performance, a first for the Zen family. The leak in question consists of two 96-core SKUs in a 2S configuration for a total of 192-cores, making it the densest yet. In addition to impressive multi-threaded capabilities, the chip recorded remarkable AVX512 performance as seen in the CPU-Z AVX-512 test.
In the AVX512 single-threaded benchmark, the Zen 4-based Epyc Genoa part performs roughly in the same league as the Intel Xeon (Golden Cove) Sapphire Rapids-SP parts. We’re looking at 627 points for Zen 4 (2.15 to 3.5GHz) vs 628 for the Golden Cove (1.9 to 3.7GHz) core. In the multi-threaded AVX512 test, the former scores 15,625 points, higher than any other Sapphire Rapids chip on the list.
Moving over to standard multi-core benchmarks, the Zen 4 Epyc part trades blows with Sapphire Rapids-SP in R15 and R20 despite having only 128 cores enabled. In the latest iteration of Cinebench, the Zen 4-based Epyc Genoa eats all Sapphire Rapids for breakfast. Even with only 128 cores, it manages to beat the higher-clocked Intel Xeon by over 40%. Similar performance can be seen in V-Ray multi-core where Genoa once again beats everything else on the table.
In the end, however, it’s important to note that server workloads are specific to each client, and an architecture beneficial to one may not suit the other. From a raw performance perspective though, Zen 4 looks solid for both PCs and data centers.
