CPU Render Benchmark

Recommended Posts

It would be useful to find out how various CPUs do with A:M, for those who are considering new machines.

 

This PRJ is designed to test the major render time hits like reflection, refraction, multiple ray-traced lights, shadows, anti-aliasing and combiner materials without touching on disk and RAM hogs like bitmaps or hair.

 

Please download this PRJ

 

ThreeTeapotsBenchmarkv005.prj

 

select the camera view in the chor.

 

If you are testing v16 or later, load this render preset when you render to file.

 

benchmark.pre

 

If you are testing v13-15 set your Options>Render Settings to "use settings from Camera" before you render to file. The PRJ has every possible render parameter set in the chor camera.

 

In either case you will need to set a file path.

 

Then hit render and wait. You should get a small jpg exactly like this in your "My Documents" folder (Mac Users may have to select a new location):

19 minutes, it is too slow for this kind of scene. I hope that hash will make an effort on the rendering for the transparency.

there is refraction... but without refraction, it's very good ;)

Did some tests using 9 instances and then again with 8 instances all at the same time on my 8 core machine. All procs were pegged/maxed out according to the task manager.

 

Average time for 9 instances at once 11:16

Average time for 8 instances at once 10:12 (one instance for each proc)

time for 1 instances 10:03

 

 

Conclusion:

 

I think its safe to say you can run 1 instance of am per proc.

Diminishing returns when I added one additional instance above the number of procs.

Also I am not sure how healthy it is for your computer to run for hours on end with all procs maxed out. My system gets very hot. Recommendation keep the air conditioning on or step it down to 1 less instance then the amount of procs you have to give the system some head room.

 

Although not exactly, It appeared that approximately one proc was in use for each instance and as projects finished up rendering the task manager dropped off consecutively.

I didnt know they made the i7 in an 8 core. I thought is was just a 4 core. Or is it? Is it the hyper threading that makes it look like 8?

 

 

If you have the time and are curiouse can you test 8 instances at once and average the render times?

This test isn't very practical unless everyone is using the same version of A:M. Render times fluctuate dramatically between different versions as modifications to the code take place. Also the choreography should include things such as particles, fog and volumetrics if you want the test to reflect more realistic production demands.

Take the PRJ and show us. People would say that but they never posted actual comparisons.

Realistic production demands are whatever someone puts in their production. There is not single test for that

 

As I said at the top, this is a test designed to focus on the CPUs processing power for A:M.

 

While everything uses the CPU Particles introduce introduce other significant variables like RAM access speed and total available RAM. Those are not the variables I'm trying to look at IN THIS TEST.

 

I want to examine as few variables at a time as possible.

 

I just want to examine the relative processing power of CPUs. Those will be informative whether you use hair or fog or whatever in your particular production.

 

Nowhere am I claiming that three teapots is a typical scene. It does however invoke a set of loads that are mostly CPU intensive and much less of all other resources. That makes it a fair test OF THE CPU.

 

 

For the moment, I just want to examine the relative processing power of CPUs.

 

 

And if I haven't mentioned it up to this point, for the moment, I just want to examine the relative processing power of CPUs.

I'll will accept that, so forget the additional variables and stick to your setup, but the version of A:M that you are using must be part of the datum. If you are unaware of the differences in versions of A:M and the impact on render speeds then I suggest that you test that first.

You see, you must set a standard base for bench tests.

-----------------------------------------------------------------

 

Please don't anyone confuse this example as a benchmark for versions of A:M. There are too many other variables that would have to be added to compare one version of A:M to another. There are many improvements in later versions of A:M that are not reflected in this test. This is simply to show that when collecting data, to compare render times on different machines, you must ensure that everyone is using the same setup, (software version and render settings).

 

-----------------------------------------------------------------

I forgot to add that these were all rendered on a single core.

Background activity was minimal: I had a QT movie open, (but not playing), and a live browser window onto a text and image website.

I mention this beacause I am surprised by the results others have shown.

The code is modified between versions to work around problems that people have found and these changes can have ramifications that affect other parts of the program. Just tweaking the routines that handle how alpha is handled,for example, could add, or reduce, the time spent in that routine by a fraction of nanosecond but if that routine is called thousands of times for every frame you render you will see a change in the final render times. Fixing things doesn't necessarily make them faster but hopefully more stable and more useful.

Surprised in what way?

The only thing that surprised me was how poorly the render works on mac, I am convinced the application of AM is running through some sort of translation instead of a truly mac coded app.

Are you surprised that your computer is 2nd to last in the race, ;) just kidding I know its not a race.

That mac time is better than before Intel macs came along and better than intel times were some years ago.

 

And this is a scene designed to take absurdly long to render on any machine.

 

Compare this to the 11Second club entry I just did. That took 2 seconds per frame to render in "Final". So Mac would take 4 seconds per frame.

It occurs to me that since the render time variation between different versions of A:M appears consistent among the various CPUs that have reported results for more than one version, I can make a multiplier that factors that out and leave us with something approaching a CPU comparison only

 

 

for example if Nancy's 15e rendertime is 9 and 15g is 10

 

and my 15g is 17 and my 15h is 19

 

I can estimate what 15e would do on my CPU (15.3) and predict that 15h woudl do about 11.2 on Nancy's.

 

By this, I could include results from someone who only tests with 15e on their CPU

 

With what I have now i can convert times from

 

13t

14c

15e,f,g,h

 

This conversion will be more reliable with the PC data since we have more of that so far

 

 

But keep posting your results if have time.

 

Thanks!

Correct me if I am wrong, but 15 was compiled differently? Could this be the reason it takes longer?

I'm sure those are elements; the CPU has to talk to the RAM just to run the program at all, but to try to minimize that bottleneck this test uses no bitmap textures and renders to a small image.

 

But I suspect CPU power is the #1 factor in how fast A:M renders.

I just added test with 14c

 

to summarize:

 

14c - 8:18

 

15e - 8:31

 

15g - 9:33

 

Not that much difference between 14c and 15e on my system (render time), BUT 15e is a bazillionbilllllion times better, faster with hair, dynamics.

 

I think OS has a lot to do with it as well as cache, bus speeds, cpu, memory speed, amount. Vista, and maybe ? 64 bit OS seem to be dawgs with A:M.

 

I bought this system over 2 years ago.

Yes. Overall performance in later versions is much faster and stable than earlier versions, when you start adding in things like hair/particles, volumetrics, dynamics, etc., etc. One of the things that Steffen is intergrating into A:M code is OpenMP, so that might be affecting performance in recent updates, but it seems to me that introducing OpenMP points towards efforts to get A:M firing on all cylinders, or rather all cores.

Here's a first attempt at a chart with the raw data, I need to find something better to visualize this. Note the lack of labels.

 

CPUComparison.jpg

 

if you go from front to back you have the same CPU running different versions of A:M. Relatively small differences

 

If you go from left to right you have different (unidentified!) CPUs running the same version of A:M. Fairly large variations.

 

I'll try to find a chartmaker that handles this better.

WOW and the winner is the i7 975. That is so fast. Can you run 4 instances at the same time and six instances at the same time after that. I am curious how well it keeps that record time when rendering multiple instances.

 

Am I correct that that is a 4 core system? How many cores come up in the task manager? does hyper threading create suit o extra cores?

Rodney, you are RIGHT!

 

I closed all A:M windows except the render window and my time improved from 19:21 to 17:10, an improvement of 12%!

 

Curiously, minimizing A:M during the render only dropped the time to 17:46

 

Setting priority to High dropped the time just a little bit to 16:56

 

Closing the other windows is easy enough to do and will probably eliminates some Graphics card overhead.

 

 

 

SO, anyone reading this... I'm going to CLOSE this thread and come up with a new, shorter, more consistent CPU test in another thread. Be on the lookout for it.

 

Thanks to everyone who participated so far!

It may be faster , but the problem is we only have two results by users that also gave results for v15. One g and one h.

 

Paul's was 24% faster but Nancy's was only 14% faster.

 

However, Paul's h was faster than his g but my g was faster than my h. Explain that.

 

It's possible that different versions do differently on different CPUs. It's possible 14 might not do any better on some and it looks like most people have moved to 15 for the features and stability.

 

(the fastest render of all was Serg with 15h, but he didn't do a run on 14 for comparison.)

 

But I want to come up with a benchmark that takes less time to run so more people will be likely to contribute data. My goal is to compare CPUs.

 

BTW, to qualify as "screamer" for me it has to go > 50% faster. ;)

It looks to me that AM14c is a screamer when it comes to rendering.

 

 

One likely reason a later version of the render wouldn't be as fast is that it has to accommodate rendering features that have been added since the earlier version. It has more things to test for and handle properly and has to do it on every pixel.

 

There are switches in the renderer you can set to tell it to not bother with certain time-consuming stuff. For example you can disable Shadows or Hair or AO. You can avoid refraction calculations by only setting IOR to 1.

 

But you couldn't have a switch for every possible rendering element. There are already more render parameters than some users can manage.

 

It's also possible that the earlier version failed to properly handle some combination of existing features (some shadows and semi transparency rings a bell here) that were technically legal but so rare that it wasn't noticed by most users or perhaps not rare but noticed only by a few discerning users. So the earlier version may have finished its work faster but not always correctly.

 

Once the problem is noticed the code needs to be expanded to always test for that particular situation and that adds to the render time.

 

My test case PRJ probably doesn't invoke any of those problem situations since everbody's renders all look identical. But there's no way for A:M to know those situations aren't there and that it didn't need to test for them until it's finished the last pixel. And since this is animation, that situation that wasn't in the last frame might be in the next frame. Back to square one on testing.
