Dear povers,

 I just installed on my new P4 1.5GHz(RDRAM128MB) with WindowsMe the POV-ray
3.1g. I compared the rendering speed running the same POV scene files(size
of 9MB) which was exported from Rhino3D modeler. The speed margin of the
1.5GHz was just 25-30% over the P3 650MHz Windows98SE(SDRAM almost 312MB).
Do I better run the POV under MS2000 instead of the Me to get much faster
raytracing?

Thanks for you help.
Jong

  Hmmm... that really sounds as a very little improvement... From what I
heared about ME, it can be the real problem. Anyhow, you can render some
of the benchs to see if the P4 is too slow, and compare with other ME
users...

Dear Jaime,

 Thank you for your help.
btw, does POV-ray also support Windows 2000 on top of NT? Sorry for my dumb
question.

  Not a big suprise. You really should have spent your money on an Athlon
(it would even have been cheaper). With a 1.2-1.4GHz Athlon the speed margin
would probably have been about 100-200% instead of that 25-30%.

  If you can return your P4 and get your money back, I would recommend you
to do it and buy the Athlon instead.

Hi Jong,

you should look at http://www.tabsnet.com/benchmark/pbench.php3.
The fastest P4 (1.7 GHz) has about the same power as a 1.1 GHz Athlon in
this pov benchmark.
A 1.4 GHz P4 runs Pov-Ray about 47 % faster than a 650 MHz Coppermine with
the orriginal 3.1g-version. So your personal P4 seems to be quite slow even
for a P4.

Beside my own 1.4 GHz Athlon runs 58 % (!) faster than a P4 with the same
frequency according to the published data.

Dear Norbert,

 Thank you for your help. I've just visted the site you recommended. I've
run the benchmark program "chess2.pov" with 'rendering priority->highest'
and 'GUI priority ->lowest'. The result was a disappointing one. It took
11min.38seconds.
Could it be due to the fact that I've got 128MB(RDRAM)?
The motherboard on my computer is Gigabyte 8TX(based on Itel 850 GPset).
Well, AMD must have done better design than the Intel.

Thanks,

Jong.

Dear Jong,




better, but is better suited for inherently unoptimized programs as pov-ray
by example; okay, the floating point units of an Athlon are better designed
as the P4 ones)).
Your numbers seem reasonable when compared to other P4 entries in the link.
Its the P4 architecture itself. The P4 is only designed to reach high
frequencies (as high as 10 GHz in some years). To be fast you have to use
speciallly optimized software. Nowadays only Quake3 seems to be optimized
with SSE2 commands. In most other areas an Athlon with "normal" architecture
is better suited.
Perhaps the best for you is to use the P4 optimized variant of the 3.1g
version of pov-ray or to change to an Athlon, sorry.

Norbert

Dear Norbert,

I am rather relieved that my numbers seem reasonble as compared to other P4's in
the link.

As you suggested, I visited the http://students.washington.edu/sschmitt/pov/ and
found that the optimzation and recompilation quite promising.  P4_Pov gave me
quite a leap(from 11 minutes to 6 min. benchmark  using 'Chess2.pov).
off-topic: Do you think the MegaPOV already optimized for the Pentium4 or
Pentium3?

I really appreciate your suggestions and help.

Jong
