SiSoftware Sandra
We are now testing in the popular SiSoftware Sandra 2021 version. We are testing the CPU arithmetic section. In this graph above we are looking at Dhrystone integer performance in multi-threading. In this test, unlike Geekbench, we find there to be absolutely no difference when it comes to strictly integer CPU performance.
However, that changes when we look at floating-point CPU performance. Here we actually find the DDR4 is 4% faster, it’s not a major difference, but perhaps the tighter timings and latencies of DDR4 are beneficial here.
In single-core integer performance, performance is identical.
In single-core, floating-point performance is identical as well.
