also I believe people have forgotten mantle http://www.pcworld.com/article/2049560/amds-low-level-mantle-graphics-could-mean-big-things-for-pc-gaming.html http://gearnuke.com/principal-technical-director-activision-says-well-support-amds-mantle/
and if your lazy and want to watch a video on mantle http://www.youtube.com/watch?v=mLt5RVGJfQY
A very important point here is It’s certain that at least one major game maker will embrace AMD’s tech. EA DICE’s Frostbite 3 engine will default to Mantle—not DirectX—in Windows rigs running GCN-based graphics cards and APUs, with the blockbuster Battlefield 4 set to be the first title to support the technology after a December update.
Mantle API can offer upto 9X or more the performance of directX or open GL API's this brings massive performance boosts to AMD / ATI / Radeon hardware in games that support Mantle for both console and PC so far Activision and EA have jumped onboard with MANTLE API.
and HSA and HUMA are all AMD / ATI / Radeon also Nvidia and Intel are not able to use these so yes next gen games for consoles and PC could very well put AMD / ATI/ Radeon ahead in performance or atleast make them even which I dont see with the performance benefits and optimizations and Mantle I can see it passing them fairly easily.
EA and Activision have already said they will default with Mantle API on PC and if hardware is not AMD GCN architecture will fall back to directX or open GL which is a huge performance decrease Mantle offers upto 9x or more the perfomance boost on exact same Radeon / ATI / AMD hardware over directX or openGL and offers no performance increase for Intel / Nvidia at all. I also forgot to mention you know how consoles get huge performance increases because hardware is used so efficient it is literally to the metal / hardware LVL well this is what Mantle brings to PC from console and xbox one / PS4 from what I understand are using the Mantle API which is crossplatform so automatically will port over to the PC and will only benefit AMD / ATI / Radeon hardware.Edited by rickcooperjr - 9/30/13 at 8:57am
