Well hardwareunboxed is trying to tell us that VULKAN has still bigger overhead than OPENGL on AMD GPUs?! I am pretty sure that both AMD and NVIDIA have pretty much same overhead on VULKAN +- few %.

hard to say not going to buy doom just to retest biggrin.gifbiggrin.gif (demo does not have vulkan active :-/)

Doom on GCN is the first (and so far only) real relevant implementation of Vulkan thumb.gif

The denial is strong with this one.

Well probably they lie.
OpenGL


And I think that i7 6700K 4.5GHz should give us 2x performance of i5 750 2.6-3.2 GHz.

So no I do not believe that benchmark

There is one way to find out: how about you take your 20$, become a PcPer Patreon and ask them to report back with fcat measurements? Mean fps averages aren't telling enough, it would be best to know how the whole spectrum of frametimes are affected by cpu overhead.

That bench is a lie.

What would happen if he would OC that phenom II x4 3.2GHz to 5GHz? Beat i7 6700K at 4.5GHz? Cmon, money is everywhere
post #3128 of 3674
like old phenom at 3.2ghz is maybe not enough to run RX480 at full speed
but so much FPS with GTX1060? i dont think so...

from 3dmark API test we allready know that both cards can do about same amount of draw calls with same CPU under mantle/DX12

Not said that. Yet, it could be the best 71FPS in test with zero frame variance, or the worst 81-121 FPS with constant dips and frame variance. Overhead could be still present in the gpu pipeline and extra cpu power might have augmented it. We just don't know it for certain.

not explaining how GTX1060 have such advantage... (i expect to hardwareunboxed to use same metric for both systems)

all DX12/vulkan tests i seen before this the RX480 had better minimal fps
