I'm aware the consoles will be largely inferior in raw numbers, my point is that a fully shared memory design means that offloading computations to the GPU is way easier and more efficient (no copying data back and forth to dedicated VRAM, CPU can get direct pointers in GPU memory and vice-versa), this means that console games can be optimized in ways that aren't feasible on PC right now.
Yeah, but most gaming PCs have 8-16GB of RAM and 2-6GB of video memory - there is so much redundancy that it's not an issue. That difference will become even more pronounced going into the future. With many next-generation titles not being able to hit 1080p @60fps it's clear that PC gaming has a significant advantage from the get-go. I already game at 1600p @60fps on PC and my system is over a year and a half old.
