Re:How many registers does an x86-64 CPU have? (2020) by vaylian on Monday February 16, 2026 @10:35AM (#47036316)
Well argued. You do have a point for physical world data. But there are also some digital world constructs that need 128 bits:

- IPv6 addresses

- UUIDs

I don't think it is critical that we get a 128 CPU anytime soon, but it would still be nice if we could handle these values with only one CPU register.
