"Also, all the cell people and the AMD people need to be quiet. Apple evaluated both. AMD has the same, if not worse, supply problems as IBM. Their roadmap is fine, but the production capacity is not.
The tested Cell as well. That processor is NOT intended for PC applications. (it was designed for game systems, not as a general use CPU) The lack of out of order execution and ILP control logic creates very poor performance with existing software. Having developers rewrite for cell would have been MUCH more work than reworking for Intel. And that's what this is, you rework your codebase in ALL cases, not rewrite it. "
