Last week the Threadripper 9000 series began shipping and as shown in our launch-day Linux testing there was stunning performance with the 32-core Threadripper 9970X and 64-core Threadripper 9980X processors. Beyond the improvements thanks to the Zen 5 microarchitecture enhancements, the new Threadrippers while working as a drop-in replacement to existing TRX50 workstation motherboards now can handle DDR5-6400 R-DIMMs up from DDR5-4800 R-DIMMs with the Threadripper 7000 series. For those wondering about the gain attributed to the faster memory modules, here are benchmarks looking at the DDR5-4800 vs. DDR5-6400 real-world performance impact for AMD Ryzen Threadripper 9970X and 9980X CPUs.
