Memory Bandwidth
AIDA64
This program has many tools for determining memory bandwidth as well as various latency values.
Memory Read
In this test, we see a result of 56,754MB/s stock, and 58,287MB/s overclocked. This puts it well ahead of the Intel systems at the same memory clock frequencies.
Memory Write
In this test, write speeds are slightly slower than Intel’s latest and greatest offering until you crank up the memory clocks. Obviously, this would happen on the Intel system as well were we to perform that same test.
Memory Copy
Again, we see the 3900X and ASRock X570 Creator clean house here coming out well ahead of the Intel test systems.
Sandra Memory Bandwidth
In this test, we see the X570 Creator and 3900X fall behind Intel’s Core i9-10900K at 32.85GB/s. When overclocked, the gains are substantial coming in at 39.28GB/s.
