Well, it depends on what you mean by 'competing with Intel on speed'. If you mean having higher-performance CPUs than the Intel equivalents then Apple probably won't achieve that. If you mean having CPUs close enough to Intel's in overall performance that few potential Apple buyers will be put off by speed issues, then that seems very possible. If Apple had to use AMD processors from now on they'd manage fine (potential supply/vendor relations problems aside).
