AMD Ryzen 7 9700X Performance With DDR5-8000 Using Corsair Vengeance 2x16GB DDR5-8000 DIMMs
👁 RAMspeed SMP benchmark with settings of Type: Copy, Benchmark: Integer. DDR5-8000 was the fastest.
In various synthetic memory benchmarks, going for the DDR5-8000 obviously makes for measurable uplift.
With HPC benchmarks like HPCG there was some small uplift going for the DDR5-8000 DIMMs. HPCG though sees a bigger difference if say opting for a CPU with 3D V-Cache.
In a number of the HPC oriented benchmarks there were some nice gains to find in going for DDR5-8000 memory on this AMD Ryzen 9000 series system, but in some cases the performance went the other direction.
In some workloads the DDR5-8000 memory was behind the DDR5-6000 memory due to the UCLK running 1:2 for the higher memory speed.
