While much of AMD's briefings for the Ryzen 7000 desktop series were focused on gaming and other consumer workloads, one of the most exciting aspects for me with the Ryzen 7000 series is AMD now supporting AVX-512. But rather going for a 512-bit FPU data path and the possibility of reduced clock frequencies and power/thermal concerns, they employed a 256-bit "double pumping" strategy. When getting the AMD Ryzen 9 7950X in the lab, exploring the AMD Zen 4 AVX-512 performance was one of the areas I was most excited to evaluate. From the benchmarks about to be shown, AMD's initial AVX-512 implementation is promising and has me all the more excited for finding it on AMD EPYC "Genoa" processors.

Today the review embargo expires on the AMD Ryzen 7000 series desktop processors ahead of their retail availability this week. Over the past two weeks I have been testing the AMD Ryzen 9 7900X and 7950X processors as the initial review samples (I should be receiving the Ryzen 5 7600X and Ryzen 7 7700X CPUs this week, AMD is staggering their review seeding of the different models). In this article to get things started are my initial Linux gaming benchmarks with the Ryzen 9 7900X/7950X compared to an assortment of other AMD and Intel systems.

AMD engineer K Prateek Nayak recently uncovered that a ~20 year old chipset workaround in the Linux kernel still being applied to modern AMD systems is responsible in some cases for hurting performance on modern Zen hardware. Fortunately, a fix is on the way for limiting that workaround to old systems and in turn helping with performance for modern systems...
