Having the 64-bit ALU and double the 128-bit XMM registers are nice, as well as the newer cores with more Intel SSE microcoded support. But the "main difference" between 32-bit and 64-bit are the memory models as I explain in this blog article here: http://thebs413.blogspot.com/2005/10/what-is-x86-64-long-mode-memory-model.html -- Bryan J.
