Cell was neither x86 for the main cores, nor had sufficient industry standards and tooling ready (OpenCL, LLVM, OpenGL, DirectX..) for the accelerator part. AMD

Cell was neither x86 for the main cores, nor had sufficient industry standards and tooling ready (OpenCL, LLVM, OpenGL, DirectX..) for the accelerator part. AMD's new offering is fully intended for mass market, while Cell was a strange mixture of HPC architecture and PS3 processor. I'd say AMD has a significantly higher chance for success, these new chips should be pretty much a no brainer for mid-end media/ gaming PCs. If they can scale it down to a much lower TDP, it could also become interesting for 'Surface Pro class' (if you can call that a class) tablets.
