I am very disappointed at you as I think you are a smart person. Now tell me why AMD will need to develop it's own proprietery design when Itanium is going to obsolete? AMD is not a suicidal teenager. The money to be made by AMD is not in the big tin, but down below...
Sounds like you're saying, that you think there's no development effort. Thanks for sharing your opinion.
He knows the AMD64 design does not use 64 bit addressing. Only 40-bit physical addressing while the data is 64 bit. Therefore the current pep talk Intel is using is that the AMD64 is not a true 64 bit processor.
AMD doesn't need a proprietary design. It already has something Intel doesn't.
I think the future instruction set market is pretty much clear now. Essentially, 99% of all world cpu's will be divided between 2 base architectures: AMD64 at mid- to high-end and ARM at low- to mid-end. That's pretty much it.
