Maybe not. But x86 certainly took over the market Itanium was aiming for.
- nine_k 9y agox86 did not. x64 did.
- cwyers 9y agoAll 16 and 32 bit x86 code is valid on x64. It's an extension, not a new ISA.
- geezerjay 9y agoYou got it all backwards. AMD64 is a complete revamp which happens to support x86 in its legacy mode. Server people care for 64-bit address spaces, and that's a feature introduced by AMD64 which is not available in x86.
