General Development "For years, PC programmers used x86 assembly to write performance-critical code. However, 32-bit PCs are being replaced with 64-bit ones, and the underlying assembly code has changed. This white paper is an introduction to x64 assembly. No prior knowledge of x86 code is needed, although it makes the transition easier."

Well, Atom has this problem as well. All Atoms support up to SSE3, some have support for SSSE3 (An extension to SSE3), and the newest support Intel VT-x.

Obviously, they don't support the AMD extensions (3D Now!, XOP, FMA4, and CVT16)

All this stuff adds complexity to the front end (One of the main targets for reducing power consumption for the Atom), but at least the back-end stages doesn't get significantly more complex.
