The AMD Ryzen 9 5900X and Ryzen 9 5950X are hands-down incredible winners. While processor company marketing claims are sometimes dubious and not necessarily relevant to Linux users and their open-source workloads/software, after testing the Ryzen 9 5900X and 5950X the past several weeks the performance has been incredibly compelling with significant single and multi-threaded performance uplift over Zen 2 and easily thrashing Intel's current desktop offerings with over 200 benchmarks conducted for launch-day.
