First off, this doesnt mean that the Xbone GPU is based on the 280X. Just no. It's based on the Bonaire - 260X, just clocked much lower with 2 CUs disabled.
If you go back and watch AMD VP's interview on the three console wins, he explicitly says that AMD has this IP portfolio that nobody else has, CPU, GPU etc. Looks like it doesnt just stop there, the SHAPE audio block in the Xbone uses the same Tensilica DSP cores that are present in the Bonaire GPU.
Previously people might have assumed that the SHAPE was a custom design by MS but after this, it looks like they just re-used the TrueAudio block in Bonaire with possibly some additional customizations (speculation on my part).
From the Xbox One Hot Chips;
From AMD's TrueAudio details;
Interesting that AMD could be using their partnership with MS to bring some of those benefits over to the PC space; Mantle (as per Anandtech) & TrueAudio (?)
edit: excuse the typo in the title. :/
