<Much like Intel's 8 128 bit registers don't *really* make much of a difference.>

Actually, according to Microprocessor Report, only eight registers were added because of the constraints of the x86 instruction set. In an x86 instruction, a register is designated by three bits each. Adding more than eight registers would have been complicated beyond belief, and SSE was already complicated enough.

But of course, all this talk about the number of added registers is pointless if software developers won't use them. AMD could have added 64 more architected registers for all I care, but if only a few programs or drivers took advantage of them, they'd be a waste of silicon. In the end, I think this VHS-vs-Beta war is going to become bad news for AMD.
