Re: How AMD will take on Intel Woodcrest: twice the FPU's

See...one natively executes vector instructions, with vector data, the
other FP operations on scalar data.

SSE is not vectored.

These days everything in the x86 world are just interfaces to more
intricate structures below.

So what? SSE units are different from FPUs are different from ALUs.

There would be a big difference. Try and think about how many FLOPs a
chip would have with 4 SSEn units...


Or 4 FP units in general for that matter, right?
