What's the difference between "re-doing x86 as a three-operand architecture" and switching to a different 64-bit RISC architecture?

What's the difference between "re-doing x86 as a three-operand architecture" and switching to a different 64-bit RISC architecture?
- DarkShikari 17y agoThe former could probably be done without a complete retooling of the chip designs.
- limmeau 17y agoI don't think it will happen, though; the ratio of people who care about the elegance of their processor's assembly language to people who buy computers is just too low. Not in form of a clean cut, at least: x86-64 brought us eight additional registers and removed the silly BCD-instructions.
