And indeed more than succeed, they invented x86_64.


x86_64's win was helped by Intel's Itanium misstep. AMD can't bank on Nvidia making a mistake, and Nvidia seems content with incremental changes to CUDA, contrasted with Intel's 32-bit to 64-bit transition. It is highly unlikely that AMD can find and exploit a similar chink in the amor against CUDA.


If they're content with incremental changes to CUDA then it doesn't cost much to keep updated compatibility and do it as quickly as any users actually adopt changes.


And indeed more than succeed, they invented x86_64.

If AMD invented the analogous to x86_64 for CUDA, this would increase competition and progress in AI by some huge fraction.


Why "if only". Intel had been around forever when AMD showed up. CUDA isn't unassailable


Only works if NVidia misteps and creates the Itanium version of CUDA.


You don't think someone would welcome the option to have more hardware buying options, even if the "Itanium version" didn't happen?
