AMD Athlon 64 was also backwards compatible to 32 bity yet nobody was confused about that from the 64 in the name, that it would somehow only run 64 bit code.

- zamadatix 3y agoIt's more the reverse of that implication. E.g. 2 years from now a 64 bit only STM chip could well be released instead of a hybrid 32 bit and 64 bit that also is fully 32 bit compatible. That's not really a problem on backwards-compatibility focused x86 where ~20 years after AMD64 the newly launched 7950X still supports booting ~30 year old 16 bit MS-DOS (and maybe older, I haven't tried).
