I think that vulkan has lower overhead than DX12. Mybe it was bug, but that bench does not tell us truth and AMD VULKAN cpu overhead is much better than showed by hardwareunboxed.

i feel the same as i seen mantle(renamed vulkan) running @2.0ghz with 100% gpu load with huge amount of draw calls on scene in star swarm

The bench definitely doesn't tell us the whole story. If you noticed, the gpu frametime counter is broken.

And here is DX12 overhead

I see R9 390 having higher avg. fps than GTX 1080 both on i3

So you agree that its a big lie or unprofessional work(newbie at work).

My first response was an objection to the methodology, as you can see this chart has minimum frametimes whereas HwU Matt's doesn't.

No hardware power target increase, so it's throttling....

... unless there are 2 bioses and he didn't use the good one... which is very unlikely.

Nitro is still the way to go.

IMO the one thing that XFX used to have that was going for them was a limited lifetime warranty(basically single card replacement lifetime as long as nothing series had happened to it, basically natural death), but since removal of that(ended with r# 200 series), option because lukewarm
