The Lineup
MLID has shared the leaked Zen4 based EPYC lineup. We saw a similar chart from yuuki_ans a while back. The leaker mentions that Zen4 has higher boost clocks as compared to Zen3 on the server platform. However, these increments fall short of AMD’s massive jump in clocks from Vermeer (Zen3) -> Raphael (Zen4) in the desktop segment.
Performance Metrics
When put up against the competition, AMD demolishes Intel’s best offerings in the server market. A lead of over 2.6x can be seen if we compare the EPYC 9654 versus the Xeon Platinum 8380. Intel’s current-gen lands right around the mid-ranged Genoa offerings. While Intel’s next-gen, Sapphire Rapids, is still en route, we do not expect it to outclass Genoa by any means. The 96 cored 9654 offers 1.7x more performance per each watt consumed. MLID confirms that this is a 400W-400W-400W SKU comparison. At the same wattage, AMD offers almost 2.6x more performance, that is insane if these numbers hold true. As per MLID, Intel’s yet-to-launch Sapphire Rapids is almost 10-20% faster than AMD’s EPYC Milan series. This puts it somewhere around 40-60% slower than the Genoa lineup.
Bergamo & Genoa-X
The cache-optimized SKUs from the Genoa-X series offer almost 1.1GB of L3 cache. Similarly, the Bergamo based 9754 is packed with a massive 128 core / 256 thread count. All these numbers spell trouble for team blue. Sapphire Rapids which is aimed at Milan is not capable of competing against AMD’s Genoa. One can thank the everlasting delays for this.
