AVX-512's Enormous Advantage For AMD EPYC 4005 Series Performance
The AMD EPYC 4005 'Grado'' processors launched by AMD in May for entry-level servers offer downright amazing value, performance, and power efficiency over the Intel Xeon 6300 / Xeon E-2400 series competition.
Among the many advantages to these budget-friendly EPYC processors is having AVX-512 support with a full 512-bit data path compared to the Xeon 6300 series only having AVX2. For providing more insight into the AVX-512 performance impact with the AMD EPYC 4005 series, here are some enabled/disabled comparison benchmarks and how they are positioned relative to the Xeon 6369P server processor. All of these tests were carried out using Supermicro server platforms and running Ubuntu 25.04 with the Linux 6.14 kernel and GCC 14.2 compiler.
