Unless you're speaking of the MMX instructions (which compete with the FPU
because the registers are shared between the two for most processors), I
don't think so. My K6 has no special instructions and is still 3 times
faster under W95 for MP3 encoding.

Even the MMX instructions can't explain a 3x difference IMHO.
