These aren't my results - apart from the K6-2 at the bottom :( - merely just
what was reported in this thread

Definately better!
Then on to the fun part. I crunched the numbers from the site you supplied
and came up with these results (plus more for Sun SPARCs, G3s etc):
Processor | Min | Average | Max | Notes
--------------------|-------|---------|-------|---------------------------
DEC Alpha 21264 | 32.75 | 50.89 | 60.49 |
AMD Thunderbird | 22.93 | 30.39 | 36.41 |
AMD Athlon | 3.55 | 29.45 | 41.39 | Includes some Thunderbirds
AMD Duron | 26.75 | 28.95 | 35.59 |
Intel Pentium2 Xeon | 20.81 | 23.87 | 26.21 | V. small sample
DEC Alpha | 17.28 | 23.64 | 44.94 | Unspecified chips
Intel Pentium3 | 17.28 | 23.64 | 44.94 | Coppermine + classic
Intel Celeron | 4.44 | 22.73 | 37.66 | All celerons
Intel Pentium2 | 9.13 | 22.11 | 44.06 |
AMD K6-3 | 9.20 | 21.49 | 29.13 |
DEC Alpha 21164 | 4.90 | 21.27 | 34.04 |
Intel Pentium Pro | 7.53 | 20.28 | 34.09 |
Cyrix M2 | 14.40 | 18.58 | 27.31 | V. small sample
AMD K6-2 | 12.52 | 18.28 | 40.64 |
AMD K6 | 10.83 | 17.96 | 29.13 |
Intel Pentium4 | | 17.02 | | One only
Intel Pentium | 5.63 | 16.75 | 27.65 |
Intel Pentium MMX | 6.68 | 15.86 | 21.63 |
Cyrix 6x86MX | 8.90 | 14.82 | 24.55 | V. small sample
Cyrix 6x86 | 7.61 | 12.50 | 26.75 |
DEC Alpha 21064 | 4.53 | 12.07 | 17.99 |
AMD K5 | 3.33 | 10.59 | 18.83 |
486DX | 4.40 | 7.82 | 10.12 |
Cyrix MediaGX | 5.40 | 5.63 | 5.83 | V. small sample

These numbers are in BPC (bang ber clock) and are not really useful except
for comparing the relative FPU grunt of each processor. Even then it's
sometimes not useful as things like memory bandwidth limitations kick in and
push the results down for higher speed processors. What I'm saying is that
these numbers have almost no practical use, and the better one would be the
BPB (bang per buck) rating of each which you can get from the site mentioned
in the last post and which I forgot to include, and can't include because
I've already posted this :)
The only use is to see that the FPU in the Alpha (the chip of my dreams :)
should really be looked at by Intel and AMD! Hehe, imagine that. Skyvase.pov
run on a TBird 1000 at a BPC rating of 50. Hmm, that's be 15.7 seconds.
Oooooohhhh yeeeaah.
Moving right along, this is how I see the results. There are several
unexpected things and several expected things (as there are with most things
:).
Expected:
1) Alpha tops the list by a large margin.
2) TBird/Athon comes second (I'm an AMD fan :)
3) Pentium 4 rates not-so-good with its high clock speed limited by memory
bandwidth.
3) Xeon beats the P2
4) K6-2's lose out to the P2 (nooooooooooooo!)
Unexpected:
1) Celeron beats the P2 (by a small margin, but lumping all the celerons
together, includeing the handicapped ones should drag it down).
2) Xeon doesn't totally cream the P2. With all the cache it should leave the
P2 in the dust!
3) Pentium MMX loses to the plain vanilla pentium. Again, a memory bandwidth
thing again.
4) The MediaGX (MMX equivilent I thought) gets smoked by even a 486!
And maybe some more but I can't be bothered analysing it any more. It's
11:30 at night and I'm falling asleep.
If anyone wants the raw results in XL form (it was a real pain trying to
extract it from the HTML, and during the process I screwed up all except the
speed, time, and processor) just e-mail me after removing the obvious from
the address (or post here if I don't respond within 24 hrs). Also, if you
want the results for antything else I've probably got it (or you can visit
the site :)
Cheers,
Michael
PS: Seeing a 7mhz 68000 take 2:12:14 to render it makes me feel better :)
