AMD Ryzen 9 9950X DDR5-6000 / DDR5-6400 / DDR5-8000 Memory Performance

For those planning on upgrading to an AMD Ryzen 9 9900 series Zen 5 desktop for Linux use, here are some benchmarks I recently carried out of several different DDR5 memory kits with the AMD Ryzen 9 9950X while looking at the Linux performance under a variety of different workloads. As part of my ongoing AMD Ryzen 9 9950X Linux testing, up today are benchmark results for several different DDR5 memory kits.

As part of my ongoing AMD Ryzen 9 9950X Linux testing, up today are benchmark results for several different DDR5 memory kits. 2 x 32GB DDR5-6400 CL32 CMK64GX5M2B6400C32- With DDR5-6400 said to be the "sweet spot" for the Zen 5 Ryzen 9000 series, I bought this Corsair DDR5-6400 kit for testing. These benchmarks are mainly being done for reference purposes in helping users who may be on DDR5-6000 right now decide if it's worth upgrading to faster memory with the Ryzen 9000 series, if DDR5-6400 indeed is being a worthwhile sweet spot for Zen 5, and the workloads where DDR5-8000 can pay off even with the UCLK there running 1:2 rather than 1:1 at DDR5-6400 and lower.
