So it’s about policy, not power.

AY: No it’s not about power.

KY: We are scalable. We are running on a toaster [laughs].

AY: Well, obviously PlayStation 4 is more powerful than Xbox One.

How much more powerful?

AY: It depends what you’re doing. GPU, like 40 per cent more powerful. DDR5 is basically 50 per cent more powerful than DDR3, but the memory write is bigger on Xbox One so it depends on what you’re doing.
