AMD is set to offer unbeatable performance with its upcoming 4th Gen Epyc Genoa processors. Leveraging up to 96 Zen 4 cores on the next-gen SP5 socket, these high-performance server and enterprise CPUs will offer unmatched compute density alongside a steady boost in efficiency. Like the Ryzen 7000 client chips, the boost clocks and TDPs have also been raised. Overall, these optimizations have resulted in a gen-over-gen performance uplift of nearly 2x over existing (64 core) Milan offerings.
Genoa will feature 10 standard SKUs ranging from 16 core to 96 core parts. The former will come with a TDP of 200W, and the latter will scale it up to 360W. The boost clocks of all the chips are unexpectedly the same at 3.5-3.7GHz. The top-end 84 and 96 core parts will feature 12 CCDs and an L3 cache of 384MB, a substantial upgrade over the 256MB limit on Milan.
Coming to performance numbers, the 4th Gen Epyc 9654 CPU, the 96-core flagship, is a whopping 2.6x faster than Intel’s fastest Ice Lake-SP part. The 40-core Xeon Platinum 8380 gets steamrolled in the 2P Spec integer throughput benchmark. It’s worth noting that the Zen core architecture has always been superior in integer workloads, while Intel has generally led in floating-point intensive operations.
The final graph shows how the performance scaling takes a giant leap across the Zen 4 family. The 24-core Epyc 9274F (at high clocks) levels with the 40-core Xeon Ice Lake-SP top chip. The 32-core Genoa manages to decisively beat it, while the 48-core parts are nearly twice as fast. Sapphire Rapids-SP will be a big step over Ice Lake, but we’re still unsure when it’ll launch. Strong 1T gains courtesy of the Golden Cove core and a healthy nT upgrade enabled by the tiled (20×4 core) design will make Intel at least mildly competitive in this high-margin segment.
