At the heart of Project Scorpio is an all-new AMD GPU, which features 40 "customised" Radeon compute units (compared to just 12 on the Xbox One and Xbox One S) clocked at an impressive 1172MHz. Microsoft has doubled the amount of shader engines and render back-ends, and quadrupled the GPU L2 cache size, which it claims has boosted the GPU fill-rate by 2.7x. That's more than enough, it says, for native 4K gaming.
