If its not impossible to include in Windows or Microsoft only supports it for windows 8 or something (maybe that is the one pseudofeature they have to force most people that hate windows 8 to use it) or sony somehow is able to pay their partners to sabotage the games for windows or something like that. If not something cracy like that happens. The software support at least for gaming will be there!
Why am I saying that. Think about it, PS4 and Xbone succeed or fail with HSA support. 99% of all highend games came in last years first on the consoles and that will not change much für ps4xbone, so all this highend games will be optimised heavy on hsa.
I mean basicly it has the raw cpu power only from a richland, which is a 4-modul cpu like my fx4150 I think, so maybe its 20% faster than my machine or so on the cpu side (needs only around 50Watt less power for it ^^) I get in Planetside 2 with medium settings or so, 20-30fps.
Planetside 2 will come out with ultra settings and 60fps. so they will use hsa heavily.
On the other site in tests of computerbase.de they messure 80fps in planetside 2, I have that maybe sometimes, too, but thats than best case szenario with no or not much player around me.
Or did I miss something and richland hat 100% more ipc? ^^
