Cerny himself admits that utilisation of GPU compute isn't likely to come into its own until year three or year four of the PS4's lifecycle. One development source working directly with the hardware, told us that "GPU compute is the new SPU" in reference to the difficulty coders had in accessing the power of the PS3's Cell processor, but also in terms of the potential of the hardware. There's a sense that this is uncharted territory, that it's an aspect of the graphics tech that's going to give the system a long tail in terms of extracting its full potential. But equally, this isn't going to happen overnight and almost certainly not in the launch period. That being the case, as unlikely as this may sound bearing in mind the computational deficit in its graphics hardware, theoretically Xbox One multi-platform games have a pretty good shout in getting close to their PS4 equivalents, with only minor compromises. Further into the lifecycle it becomes a question of whether PS4 GPU compute becomes a significant factor in development when the additional effort would not yield much in the way of dividends for the Xbox One version of the game.
Sounds like the waitstation to me
