While Intel has supported CPUID Faulting on processors going back to Ivy Bridge and supported this feature in the Linux kernel since early 2017, only now the AMD support is being wired up and making use of the existing Intel code paths...

AMD EPYC 4345P 8-Core CPU Performance

Phoronix - Mon, 06/09/2025 - 23:00
Last month with the launch of the AMD EPYC 4005 "Grado" series for entry-level Zen 5 servers we ran benchmarks of the AMD EPYC 4565P and EPYC 4585PX processors as the top-tier 16-core CPUs. They delivered an excellent combination of performance, power efficiency, and most of all value for those looking to assemble an AM5-based budget-oriented server in 2025 and beyond. Those processors destroyed the Intel Xeon 6300 series competition's flagship, the Xeon 6369P that is simply 8 cores / 16 threads in 2025... Being curious about the core-for-core performance between the AMD EPYC 4005 series and Intel Xeon 6300 series, I got my hands on an AMD EPYC 4345P as the Grado 8-core processor to see how it performs against that Xeon E-2400 series replacement as well as how the performance compares to the prior generation 8-core EPYC 4344P.
