When Pascal/Polaris graphics cards releases and Intel Kaby Lake CPU's, consoles will have even bigger competition.
Even from Intel with the integrated graphics.
Iris Pro Graphics 580, GT4e – 72 execution units with 64 or 128 MB of eDRAM, 1152 GFLOPS at 1 GHz
So laptops and prebuilds will have the same power as the Xbox One in 2017.
