Initially, the leaked Genoa flagship codenamed ‘ EPYC 9664‘ featuring 96 cores / 192 threads surfaced. This CPU is the fastest x86-64 ISA chip leaked to the market. Having an official TDP of 400W may make it unfavourable for a few, although one should bear in mind that Intel’s best offerings consume upwards of 700W. Then, the EPYC 9654, which is a slightly slower than the 9664, was presented infront of us. This chip had insanely high L3 cache bandwidth of over 10TB/s which was over 9x faster than Intel’s Sapphire Rapids-SP Xeon QS. Today, over at Geekbench 5, an unknown CPU appeared termed as “Zen 4 Genoa ES” by HXL on Twitter. If we take a look at the specifications, the 32 core / 64 thread configuration along with 128MB (4x32MB) of L3 Cache puts it close to the EPYC 9334. This CPU utilizes the Zen4 architecture which is set to arrive for the mainstream market on the 15th of September via AMD’s Ryzen 7000 CPUs. The test bench features around 32GB of RAM and the SKU used has an OPN Code “100-000000479-13“. The possible EPYC 9334 is running at a base frequency of just 1.20GHz, however, we doubt that this will reflect the final numbers. Do note that this test was conducted on the Linux x86 (64-bit) OS, so a direct Windows comparison will not result in a fair competition. Performance wise, this CPU scores a really impressive 1126 points in single core testing which is bumped up to 4646 points in multi core testing. The multi-core has a huge discrepancy in contrast to the single core test, which may due to various cores/threads being disabled. These CPUs are set to arrive sometime in Q4 2022.
