The Xbox One vs. PlayStation 4 graphics spec comparison is stark to say the least. Both systems utilise AMD's GCN (Graphics Core Next) architecture, but Sony's rendering tech has 50 per cent more raw computational power than the Xbox One equivalent - and that's factoring out other differences between the systems. The question is, what is the impact in actual gameplay conditions?Behind the scenes, developers have suggested to us that we shouldn't jump to conclusions about the extent of the PlayStation 4's superiority, and that the 50 per cent boost in GPU power emphatically won't result in a likewise boost to in-game performance. It's a topic we raised briefly with PS4 chief architect Mark Cerny when we met up with him a couple of weeks ago:
"The point is the hardware is intentionally not 100 per cent round," Cerny revealed. "It has a little bit more ALU in it than it would if you were thinking strictly about graphics. As a result of that you have an opportunity, you could say an incentivisation, to use that ALU for GPGPU."
