Digital Foundry just posted an analysis of the scalable console patent.
Everyone READ the entire digital foundry article. It's easy to understand. Now add that OpenCL, OpenMP and Cuda allow for cross platform, distributed processing and forward compatibility. This is the idea behind the AMD sponsored Fusion HSA Foundation and allows handheld openCL code to be run on a Xbox720 or cloud server farm and served as video back to the handheld.
This is the 2011 distributed processing Sony patent, the original Cell vision but now platform/CPU agnostic. This is why there is WebCL proposed by W3C. The Vita GPU design, by design (2008) supports OpenCL and there is a 2008 library from IBM that supports OpenCL on the Cell processor. This has been in planning for years and is part of the forward thinking plans of everyone. AMD has been planning their building block HSA Fusion for 5 years but not talking about it (Started in 2008). OpenMax IL 1.2 was delayed from 2008 till late 2011.
We are just now being exposed to this because onQ123 and others have been digging into next generation game console technology. I had alot of the pieces but only in the last few weeks has it all tied together.
On the software side there are new standards and on the hardware side AMD's building blocks and HSA Fusion multi-cpu SOC. The out-of-order branch prediction of X86 processors leveraged to support a HSA jit engine + OpenCL.
Both the Xbox 720 and PS4 should be X86. Durango may be the Xbox361 and Oban the SOC or building block to make the SOC , Orbis is not the PS4, everyone has been jumping the gun and a refreshed Xbox360 and PS3 coming this 2012 season have been confused with next generation. The 1PPU4SPU Sony patent filed 9/2010 needs to be looked at again considering the Microsoft powerpoint was released 9/2010 and a Linkedin Sony employee profile has him starting work on next gen and Vita 9/2010 and the Microsoft-sony.com domain registration happened the same month the Digitimes PS4 rumor surfaced and that has to be the refreshed PS3 that just passed through the FCC.
