DDR5-6400 vs. DDR5-4800 R-DIMM Performance For Threadripper 9980X / 9970X CPUs
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.
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. AMD had supplied GSKILL T5 Neo F5-6400R3239F32GQ 4 x 32GB DDR5-6400 CL32 R-DIMMs as part of the Threadripper 9000 series review kit.
