Simple speedtesting

[luppa]

Hi all! My first post....

I was in the middle of a modelling project, and I thought to test the rendering speed with my own machine and my father's new (and cheap) laptop. After that, I asked my friend to render the same scene with his machine. Some settings (same for all machines):

bidirectional: 1
height: 600
hybrid: 0
large_mutation_prob: 0.40000
max_change: 0.01000
max_num_consec_rejections: 85
maxdepth: 10
metropolis: 1
ray_origin_nudge_distance: 0.00010
width: 800

Indigo was used in GUI mode, set to halt at 400 samples per pixel, save period and display period at 120s. I took all the textures off and used sunlight, so it would be easier to set it up in an other machine.

Machine specs and results (some specs from CPU-Z):

The machines weren't used otherwise during rendering. The results confuse me, did I do something wrong, I thought machines would be a lot faster nowadays, than my P3...

The actual reason I posted this, is that I'm thinking of upgrading my computer, and I want to know different results from different computers. Is there a good test scene that people on this forum could render with their own computers and then post the results here? I would be happy to test with this P3 and the laptop. I think there was a similar testing project going on with Blender at one time...

Welcome to Indigo Luppa...
the difference in speed between your P3 and the Core2Duo that the core duo runs ~394% of your p3, or ~ 197% per core. Compared to Mhz, there is a small speed loose for each additional core. testing the Core2duo on 1 thread would show...

Indigos rendering speed is based on pure CPU Mhz power, there is some SSE1 & 2 optimization, but as far as I can remember, its not totally-über-optimized, but just some additions are done...

If you are going to buy a new rig, and 3D rendering stuff is what you are interested in, the is NO WAY around a 4core system, even a intel skulltrail 2xquadcore system could be interesting, or building a cheap, but powerfull cluster of renderslaves, combined to a powerfull über-computer using linux...

BTW: Indigo 1.0.7 is available as a 64build too, no need to use v0.9 test 9 anymore

I did these renders a while ago...
Yeah, it seems that quadcore is the way to go. Still, it would be nice to compare results with other computers using a standard (or a few) test scene

I looked at general testing results on Tom's hardware and on other sites, but for some reason it's hard to find comparable results for high-end CPUs like Intel Xeon or AMD Opteron and others. Not that those results would tell anything about speed with Indigo. And, it's hard to compare those results to my old computer

Why would I need to use linux in "the" übercomputer? It have the impression that Windows would have some trouble using memory over some limit, but other than that... to clarify, I have been using linux as my main OS for a few years in the past, but I gave it up, happily (not trying to start any wars, use whatever you like, people)

I did some benchmarking on my quad when i first got it, there are some comparisons with other users' machines in this thread:
