1. Re: Red 4K to DPX Benchmarks More Quadro #s
cts51911 May 7, 2010 3:28 PM (in response to Scott Chichelli)So the 3 layer GTX 480 is the fastest? Not sure I'm reading the info. right.
480GTX
3 Layer - 18:38
vs.
Quadro CX
3 Layer - 21:02
With this configuration?
980X at 4.0GHz
4 Drive Raid 0
Thanks for the info!

I have a question, did you have to do anything special to get the GTX 480 working?
Fermi is paying off!

GTX 470 works too along with other Cuda 3.0 cards with about 775 megs of ram...Even mobile cards. Most of the 200 series cards with enough memory "seem" to work. The jury is still out.

Scott Chichelli May 8, 2010 7:55 AM (in response to cts51911)correct
however the 285 with 2 sets 2 drive 0 was 18:28 and dont forget without a quadro if you go past 3 layer you have to render all first which adds a good amount of time.
there are some comments that need added for playback. i should probably let Eric do that.
right now for Red4K it looks like playback is better on the Xeons but render times are slightly faster on the 980x

You are referring specifically to Red4K related to the 3 layer 285 GTX limitation?

Scott Chichelli May 10, 2010 5:49 AM (in response to Chuck A. McIntyre)correct! past 3 layers with the 285/480 forces you to render all lyers not just the ones past 3 thus adding a decent amount of time to your render/encode.
for many the 285/480 is all you need, but for those who do more than 3 layer and time is money i hate to say it but the Quadros are recommneded.
the $ will be made up in time saved very quickly.
unless some clever guys figures out how to get past it.

7. Re: Red 4K to DPX Benchmarks More Quadro #s
ECBowen May 10, 2010 7:12 AM (in response to Bill Gehrke)The 480GTX performed about the same as the 285GTX for 3 layers and better for the 4 Layer. I did see the effects render issue in my playback though so I would definitely wait for the Fermi update before you make the jump. The 3 layer export and playback really didn't push either GPU that hard though overclocking the CPU did finally raise the GPU usage up to around 50% on the 480GTX. That means there is allot of idle time for the GPU depending on how many effects per layer. This was with 5 effects per layer if you count the 50% scaling to each video clip.
The R3D material handled much better in CS5 with playback but still is limited to 1/4 scale playback for more than 2 layers with effects even on the Dual Xeon 5660's. The CPU load on the Xeons rarely hit 100% on 1/2 scale playback and fluctuated around 50%. The 980X pegged and stayed at 100% most of the time trying to playback 1/2. If you rendered out the effects though, you could play all 4 layers at full scale without any issue. Also the CPU usage stayed at 25% or lower and the GPU usage fluctuated around 8%. What that means is you will likely be rendering your R3D allot to play it back full or half scale so the Quadro is really a waste there unless you don't mind 1/4 scale playback.
On AVCHD material the Dual Xeons 5660's took longer to export but had allot more overhead room to add layers with effects with the 285GTX layer limitation and play them back realtime. Since AVCHD is one of the highest compression codecs, you will see a significant performance gain with the other predominant codecs if you edit more than 3 layers often with effects. The trade off is just slower export times than the 980X running at 4GHz. If you need faster render/export times and you often edit 3 to 4 layers or lower, then the 980X is the way to go. Please let me know if you have any questions.

Can you elaborate on the "effects render issue in my playback" you saw.

9. Re: Red 4K to DPX Benchmarks More Quadro #s
ECBowen May 10, 2010 7:36 AM (in response to cts51911)There was a strong yellow in playback almost like watching an old movie or adding an old movie effect. I would say it was the brightness and contrast effect that did not render right.

techflow2010 May 12, 2010 7:14 AM (in response to Scott Chichelli)Hi. Thanks for these helpfull test
What I would like to see is a test with 5D MK II or 7D video files.
Basically render time with and without GTX 285
Most helpfull would be if lenght of the rendered end result would be one of the folowing:
1 minute , 10 minutes or 30 seconds. so I can calculate the benefit from the card vs cpu rendering
I'm trying to figure out the most cost efficient workflow.
Allso what would be interesting is comparing different rendering codecs.. how does the rendering speed get's boosted for the different codecs when using A GTX 285.
something like this.
with GTX 285
1 minute render speed for WMV
1 minute render speed for (quicktime)
cpu only
1 minute render speed for WMV
1 minute render speed for (quicktime)

12. Re: Red 4K to DPX Benchmarks More Quadro #s
techflow2010 May 12, 2010 7:35 AM (in response to ECBowen)7D material.
there is a file with these setails:1/4,000 sec Manual Exposure
(10.9 seconds, 60.9 MB)http://www.imaging-resource.com/PRODS/E7D/E7DVIDEO.HTM
7D*s video is comparable to 5D MK II's . That is the closest clip i found with my quick check that is close to 10 seconds.
AND
There are raw video in the Dpreview's test of the cameras.
7D here (8 second clip at the bottom)

5D here (12 seconds at the bottom)
http://www.dpreview.com/reviews/canoneos5dmarkii/page19.asp
If the use is non comercial I usume they wont mind.

ECBowen May 12, 2010 9:11 AM (in response to techflow2010)Excellent, I will contact them and see if they mind us using their material for performance benchmarks.
BTW Please reference our benchmark page for easier viewing now since it's up.
