Various tech sites jumped on this as it was clear that there was something very odd with these benchmarks. GamersNexus analyzed the results in-depth and had an interview with Principled Technologies, giving the company the chance to explain how it reached its results:
TechPowerUp has some more analysis over here. Here's a small snippet:
The Principled Technologies response contains no explanation as to why they used four memory modules, or a 4-module + dual-rank module configuration for mainstream desktop processors that feature dual-channel memory controllers. It has been common knowledge for close to two years now, that AMD Ryzen processors offer stunted performance when saddled with dual-rank memory modules, more so when all four memory slots of the motherboard are populated.Basically, best to ignore these results and wait until the NDA expires to check reviews from your favorite tech sites.
