While today we have both the AMD EPYC “Genoa-X” and “Bergamo” launches, Bergamo is clearly the more impactful of the two. That is a lot to say given we know that Microsoft Azure is very fond of Milan-X and Genoa-X. Let us put together a few key points:

• The primary change for Zen 4c cores from Zen 4 is a halving of L3 cache.
• The AMD EPYC 9754 is showing performance ~3x a 128-core Arm competitor at 1.5x the power.
• An AMD EPYC 9754 is often twice the performance of 2019’s AMD EPYC 7002 “Rome” 64-core parts.
• On most non-HPC-focused workloads, expect the AMD EPYC 9754 to be 15-20% faster than the AMD EPYC 9654. That is not a straight 33% as we would expect due to the core count increase, but AMD is getting scaling from the increased core count even with a drastically reduced L3 cache size.
• AMD seems to have figured out an elegant way to reduce turbo clock jitter, especially at maximum load. That helps a lot with SLA on a loaded system.
• Cloud-native processors will make up a huge segment of the market.
