Not this again. AMD is not going to outsource CPU production. It makes no sense on many levels. Firstly, TSMC is likely not capable of producing an AMD CPU their process is not advanced enough. And if TSMC does upgrade their tooling to do it, the end product would very likely end up worse, higher power, lower clocks etc.

Secondly, by producing the CPU at TSMC, AMD would probably make less per processor.

What this is really about is Fusion. AMD is going to have the GPU part of fusion fabbed by TSMC. The first real fusion product will be a side by side die arrangement, the GPU portion minted by TSMC, the CPU portion by AMD. The two are then slapped onto a single substrate.
