Curious, why are you pulling out one core on the PS4 for audio? It can also do some with 4 CU's of it's GPU (I know) and does have a little audio chip. |
Well, I did it both ways, hence -9% raw.
PS4 audio chip just does compress/decompress.
Doing audio on CU's is apparently pretty darn difficult (difficult to synchronize due to high GPU latency).
Regardless, if they are forced to use up some of their 4 "extra" CU 's on audio, I think that's a win for X1. You would have to adjust those GFLOP numbers for PS4 down.
From what I've heard SHAPE is equal to about 1 core of audio processing after Kinect reserves. This is a VERY ballpark figure. SHAPE could be even more of a beast, but much of it (beyond the 1 core) is reserved for Kinect audio processing (which IMO sucks, I hate when X1 is weaker for Kinect's sake).
