Wow, purepc used DDR4-2133Mhz for all newer systems. Knowing how much this one thing gimps Ryzen's gaming performance I'd immediately disregard their results. They couldn't try one notch higher for DDR4 on all supporting systems? KL easily supports 3.2Ghz(and higher) DDR4 while Ryzen with latest bios updates works with up to 3.2Ghz dual channel single rank memory.
What a mega fail of a test.
