AMD Ryzen Threadripper PRO 9995WX Performance With TRX50 + Quad Channel DDR5
Overall the performance of the Ryzen Threadripper PRO 9995WX was better than expected when pairing with quad channel DDR5-6400 RDIMMs on a TRX50 platform rather than eight channel memory on WRX90. For some workloads the 96 cores fighting for access across the four memory channels was a bottleneck while
On a geo mean basis when testing the Threadripper PRO 9995WX on a TRX50 + 4 x DDR5-6400 setup like the other Threadripper 9000 series processors, the PRO 9995WX was just ~3% faster than the 9980X overall. But having four memory channels for 96 cores / 192 threads was a bottleneck for many workloads. As shown in the individual benchmark results though there still are a lot of area where the AMD Ryzen Threadripper PRO 9995WX is suitable for use with four memory channels for a lower-cost workstation option.
The biggest gains from the Threadripper 9980X to Threadripper PRO 9995WX while running with four memory channels were in the rendering workloads like OSPRay Studio and Blender, some crypto workloads like Xmrig and OpenSSL, the Stockfish chess engine, and others. See all 200+ benchmarks for more individual data points of weighing such a workstation configuration.
On average the Threadripper PRO 9995WX was consuming 297 Watts with a recorded peak of 374 Watts, similar to the Threadripper 9970X and 9980X processors.
Thanks to AMD for supplying the Threadripper PRO 9995WX for Linux testing at Phoronix and will hopefully have eight channel complementary benchmarks to publish soon.
