AMD Ryzen 9 9950X DDR5-6000 / DDR5-6400 / DDR5-8000 Memory Performance
For AI workloads like using PyTorch and TensorFlow from the AMD Ryzen 9 9950X CPU, the CMK64GX5M2B6400C32 was a nice sweet spot and yielding similar performance to the 2 x 16GB DDR5-8000 CL36 CMH32GX5M2X8000C36.
For those wanting to see even more benchmarks from these four DDR5 memory kits tested on the AMD Ryzen 9 9950X Linux desktop, see this result file. Overall though the main takeaways are that the DDR5-6400 memory was indeed a nice sweet spot and if going for best value there are kits with larger memory capacity at similar price to the DDR5-8000 memory kits as shown. The Corsair Dominator Titanium RGB 2 x 24GB DDR5-8000 CL38 CMP48GX5M2X8000C38 memory kit was the only one problematic and yielding sporadic segmentation faults under some demanding workloads. Of the memory kits I bought for this Ryzen 9000 series DDR5 memory testing, the 2 x 32GB DDR5-6400 CL32 Corsair CMK64GX5M2B6400C32 kit did the best overall and allowed for similar performance at roughly the same cost to the 32GB DDR5-8000 memory tested.
