Computer Model and Performance

EDIT: Most people are going with the pig test, so I will put that in bold here.

Menu Bar > Help > Cheetah3D Samples > Rendering > Pig.jas

Pig.jas file.
Still life render - height x width 2000x2000
Camera max samples set to 16x16



This topic started in another thread about the new Mac Pros but deserves a thread of its own.

Use the samples included with Cheetah3D on your machine to compare rendering speeds and discuss the results here. You could use the result here to choose which computer to upgrade to. Or just have fun.

iMac (late 2012) 3.4GHz i7, 16GB RAM, GTX 680M, 3TB Fusion drive OS: 10.9 Mavericks
Rigid Body Spiral = 770.09 sec (animation render)
Cartoon Plane = 137.77 sec (animation render)
Pig.jas (max 16x16, 2000px by 2000px) = 30.06 sec (picture render; note the changes to the settings)

Mac mini (2,6GHz i7 with 16GB RAM and 3TB Fusion drive): OS: 10.9 Mavericks
Mac mini (Rigid Body Spiral) = 904.95 sec (animation render)

And here I was thinking I had a fast machine.

not sure about totally same settings?!

Happy New Year everyone!

Had some spare time today so I ran a few more renders, just opened the file and rendered without changing any settings.

iMac (3.4GHz, 16GB RAM, Fusion, 10.9.1)
Cheetah 6.3

Particle Marty.jas = 298.64 sec (animation)
Flag.jas = 138.11 sec (animation)
Soft Body Anchor.jas = 101.24 sec (animation)
Rigid Body Pivot.jas = 279.59 sec (animation)


I'm hoping to see some new Mac Pro data soon (especially the 6-core version); I am considering buying one but want to see how well it does.

Strange that I get 89.23s on my early 2008 Quadcore MP... Shouldn't you 8core be nearly double as fast?

I would think so. Is it possibly due to using Cheetah 5.8 rather than the current version ? Maybe I should download the current demo and check ?

How much variance is to be expected on renders in general - when no other major processes are running other than say the browser? I just downloaded Cheetah 6.3 and re-did the Pig.jas render test and got three different results:

47.75 sec.
41.82 sec.
32.99 sec.

Further to my earlier post - just tried the demo of 6.3 Cheetah. Same file and computer as before :
91.97 seconds.

Man that stinks. I need a new computer.

That's interesting (the variance in render times), so I ran the pig test again five times and got a very consistent score.

30.15 s
30.23 s
30.11 s
30.32 s
30.26 s

Could your computer have some hidden process running? Some app checking for updates, for example? (I'm just guessing here)

I'm getting more consistent results now.

First time I run the test it is in 40's, all other renders in 30s with about a one second variance.

46.92
33.24
32.92
33.45
34.02
35.02

(Yes, I copied and pasted :) )
I knew my machine was not up-to-par with more modern machines, but am surprised how much faster a 2012 iMac is!

Only Cheetah and Safari running.

Time 1: 84.07 seconds.
Time 2: 81.34
Time 3: 80.22
Time 4: 83.04

Man, you guys are killing me. I have been waiting and waiting to upgrade my computer and am definitely planning on getting a nMP. I was hoping to wait until it had been out for a few months but these times are quite eye opening as I, too, thought I had a fast computer. sigh

My inclination is that I want 12 cores and damn the torpedoes but cooler heads are prevailing and I am thinking of getting the hex core like everyone else and the D700's because, you know, why not.

Of course, the main thing that I want to use Cheetah for, other than everything else I use it for, is to render architectural animations with SU models at 720p minimum. When 31/2 minute animations were taking 7 days to export (hard shadows, no natural sun, minimal or no point lights), I pretty much gave up. And knowing that the 12 cores would certainly be faster, right now, sure makes me want them, but $3000 is brutal and just doesn't make sense. Martin, that you are rolling with OpenGL gladdens my heart! Knowing me, though, every time I watch 6 buckets rolling across the render screen instead of 12 I will kick myself.

Watching macforums, it is sounding like the CPU may actually be upgradable, which would sure make my immediate decision easier. Really looking forward to seeing what the nMP does with the pig!

hey paul, seeing the difference between your 3.0 and my 3.2 even more makes me just want the fastest mofo I can get, right now, you know?

oh to be rich...
