Yes, RAM speed matters a lot for 2X and even more for 4X. Running the same 6200CL30 with optimized sub timings on my 7950X
Here are my results from this alpha for a 5090:
i got decent uplift in Artemis, Iris and Proteus 1X performance from 5090 over 4090. Although I see some 10% run to run differences in 1X results (not really in 2X/4X). Maybe something to improve in the benchmark.
2x and 4x seem to be limited by RAM/CPU speed.
Nyx fast, Chronos/Chronos Fast and Aion also see good uplift.
Most other models seem to be about the same.
Gains seem to be in-line with the general performance difference of 20-30% from 4090 to 5090.
