When The Tech Report first conducted their review of the RX 470 they saw benchmark behaviour very different from any other GPU in that family but could not figure out what it was and resolve it before the mob arrived with pitchforks and torches demanding they publish or die. 

As it turns out there was indeed something rotten in benchmark; incredibly high DPC on the test machine.  Investigation determined the culprit to be the beta BIOS on their ASRock Z170 Extreme7+, specifically the BIOS which allowed you to overclock locked Intel CPUs.  They have just released their new findings along with a look at LatencyMon and DPC in general.  Take a look at the new benchmarks and information about DPC, but also absorb the consequences of demanding articles arrive picoseconds after the NDA expires; if there is a delay in publishing there might just be a damn good reason why.

"We retested our RX 470 to account for this issue, and we also updated our review with DirectX 12 benchmarks for Rise of the Tomb Raider and Hitman, plus full OpenGL and Vulkan benchmarks for Doom."
