Don't know why you were downvoted. Modern x86 chips not only have 128-bit vector registers, but also 256-bit ones: http://en.wikipedia.org/wiki/Advanced_Vector_Extensions (And while one could argue that a vector register isn't a "real" general-purpose register, the primary difference is that you can't perform fullwidth arithmetic, which is of very little use > 64 bits anyway.) |
