AMD's upcoming 4th Gen EPYC "Genoa" processors are expected to benefit from Automatic IBRS, a new feature in the Linux 6.3 kernel. This feature provides better performance than the current Retpolines implementation for mitigating Spectre V2. The Automatic IBRS support is new to Zen 4 processors and will be enabled by default in Linux 6.3. Benchmarks on the AMD EPYC 9654 server processors show the performance improvement with Automatic IBRS. This feature is similar to Intel's Enhanced IBRS and will be available on both client and server CPUs. The patches for enabling Automatic IBRS have been in the works since November and are now being finalized for the upcoming kernel release.
AMD 4th Gen EPYC 9654 "Genoa" AVX-512 Performance Analysis

The AMD 4th Gen EPYC 9654 "Genoa" processor delivers impressive AVX-512 performance without negative impacts on power consumption or clock frequencies. The AVX-512 implementation in Zen 4 is robust and efficient, outperforming early generations of AVX-512 on Intel processors. The EPYC 9654 2P performance with and without AVX-512 usage was tested, showing the impact on raw performance, performance-per-Watt, CPU power consumption, core temperature, and peak frequency. The testing was done on Ubuntu 22.10 with GCC 12.2 and the Linux 6.1 kernel.
AMD EPYC 9654 shows what 96 Zen 4 cores can do by outbenching a Ryzen Threadripper PRO 5995WX by almost 30% on PassMark
The AMD EPYC 9654 processor has outperformed its competitors on PassMark, surpassing the Ryzen Threadripper PRO 5995WX by almost 30%. With its 96 Zen 4 cores, the EPYC 9654 achieved a CPU Mark of 124,119 points, setting a new benchmark. Although it has a slower single-thread score, the EPYC 9654 showcases AMD's excellence with its 5-nanometer manufacturing technology and support for AVX-512, PCIe 5.0, and DDR5. The EPYC 9654's reign may be short-lived as the upcoming 128-core EPYC 9754 chips are expected to showcase even greater capabilities.
AMD EPYC 9654P
The AMD EPYC 9654P CPU performs well in various tests, including integer and floating-point math, finding prime numbers, sorting random strings, data encryption and compression, physics simulations, and extended instructions. It also has a decent single-thread performance. However, there is not enough data available to create a distribution graph for its CPU mark.
