Okay, some random runs incoming. I've run this from a boot floppy on some machines (as: fpu486.exe > fpu.txt) so i hope you made sure that floppy i/o when outputting each line doesn't impact the timing.

Intel 386 @ 25 MHz, with Cyrix FasMath coprocessor chip also @ 25 MHz:
(Yessss it actually runs on a 386, good job ;D)

FPU512 486 v0.34
----------------
64 53069.448763
128 26657.252362
192 17798.900124
256 13359.474571
320 10692.530310
384 8913.194965
448 7641.568234
512 6687.479930
----------------

Test Value: OK

Cyrix 5x86 100 MHz ( FPU ) x 0.053150
Intel P54C 75 MHz ( FPU ) x 0.043330
AMD K6-2 450 MHz ( FPU ) x 0.007885
Intel PIII 450 MHz ( FPU ) x 0.005914

Intel Pentium 1 @ 133 MHz:

FPU512 486 v0.34
----------------
64 53069.448763
128 26657.252362
192 17798.900124
256 13359.474571
320 10692.530310

Test Value: OK

Cyrix 5x86 100 MHz ( FPU ) x 2.250379
Intel P54C 75 MHz ( FPU ) x 1.834598
AMD K6-2 450 MHz ( FPU ) x 0.333839
Intel PIII 450 MHz ( FPU ) x 0.250379

Now, the P1 @ 75 MHz you actually wanted:

FPU512 486 v0.34
----------------
64 53069.448763
128 26657.252362
192 17798.900124

320 10692.530310
384 8913.194965
448 7641.568234
512 6687.479930
----------------

Test Value: OK

Cyrix 5x86 100 MHz ( FPU ) x 1.226634
Intel P54C 75 MHz ( FPU ) x 1.000000
AMD K6-2 450 MHz ( FPU ) x 0.181969
Intel PIII 450 MHz ( FPU ) x 0.136476

And lastly an Intel P3 @ exactly 1 GHz:

FPU512 486 v0.34
----------------
64 53069.448763
128 26657.252362
192 17798.900124
256 13359.474571
320 10692.530310
384 8913.194965
448 7641.568234
512 6687.479930
----------------

Test Value: OK

sec(s) 0.055000

Cyrix 5x86 100 MHz ( FPU ) x 26.963636
Intel P54C 75 MHz ( FPU ) x 21.981818
AMD K6-2 450 MHz ( FPU ) x 4.000000
Intel PIII 450 MHz ( FPU ) x 3.000000

If you need full CPU specs tell me which hardware info thingy to run and you'll get the output of that, too

I also have a P1 @ 100 MHz and a bunch of other chips stowed away but no time atm to put together a machine to run those....
Hope this was helpful regardless.

EDIT: Why don't you just attach the files to your posts? MEGA is for huge warez, not tiny files like this 😜
(Consider the craptons of JS, CSS and web noodles loaded only to transfer your tiny file. pretty sure that was larger than DOOM!)

Thanks!
I made a more timing accurate version (P7) for faster CPU's (ms) .

Can you run P7 version on 1Ghz if you have time 😉

I'll give them a shot on one of my 486DX2/66 or 486DX2/50 and see how they go...

The result for amd 486dx2/66 was 3,428 seconds
