I seriously doubt GIMPS benchmarks will have an impact on P4 sales!
I don't know ... as I understand the situation, Intel have been
forced to drop their P4 prices way down because the units just aren't
shifting ... magazine keep printing

I just completed my first 512K FFT using the new SSE2 instructions!
The 512K FFT handles exponents up to 10.3 million.
Timings are as follows:
1.4GHz P4, old code:0.126 sec.
1.4GHz P4, new code:0.048 sec.

I have a few more optimizations up my sleeve. I think my goal

As opposed to 10.32 million with the 8087 code? If so, that's pretty
good - I thought you might have lost more precision than that.
I haven't figured out the upper limits yet. I expect the limits to be roughly
what Ernst Mayer's
