Well, the DX12 benches are more for AMD vs
nVidia, he was asking more directly about AMD vs
Intel...
Unfortunately, AMD's issues from a CPU perspective aren't going to be solved by DX12... Hence why they need to make sure they execute, and execute WELL on the Zen release. I'm actually somewhat excited to see what they can do even though I've gone to the blue side with most of my CPU choices as of late (although I'm still rocking a nice dual CPU Opteron based server in my basement at the moment).
Haswell i5-4670k desktop, Asus 2u Xeon X3450 support server, dual Opteron main server, Pentium G3220 based media server (replaced aging Phenom II setup and saved 120+ watts continuous load), Intel J1900 HTPC, Asus UX31 laptop.
Hate to say it, Intel makes some damn efficient CPUs.
