Giants2.0 writes "Ars Technica has a brief article detailing some of the prospects of AMD's attempt to fuse the CPU and GPU, including the fact that AMD's Fusion will modify the x86 ISA. From the article, 'To support CPU/GPU integration at either level of complexity (i.e. the modular core level or something deeper), AMD has already stated that they'll need to add a graphics-specific extension to the x86 ISA. Indeed, a future GPU-oriented ISA extension may form part of the reason for the company's recently announced "close to metal&" (CTM) initiative.'"
