After testing SVP12 on different computer equipped with Quadro K5000, have interesting info and a question
Today I had access to a fairly fast machine ( 6-core Xeon, Sandy Bridge) equipped with an Nvidia Quadro K5000. I installed the SVP12.770 trial and ran through the “red car” benchmark.
Something interesting. Using the Main Concept AVC encoder in either CUDA, OpenCL or CPU only mode, the render time was about 3:26. Not much different with any option. (and just in case anyone asks, yes Vegas was properly detecting the Kepler card, and for video preview, the playback was very, very nice even at Good or Best).
Then I tried the Sony AVC encoder and was surprised! using “render using GPU” the GPU utilization went to about 60%, CPU dropped to less than 40%, and it completed the render in 2:04 .
So, clearly the Sony AVC encoder can use Kepler.
That got me thinking about my home system, my old slow T7500 with Quadro 2000. On it, I can get about the same render time in Main Concept using CUDA as I was getting on the 6-core Xeon ( ~ 3:26) . But my Sony AVC renders are about 3:37 and the preview playback is laggy.
I might be willing to pick up a K5000, hoping that someday MainConcept will fix their encoder, and in the meantime enjoy the better preview and better Sony AVC encoder performance. But I would hate to loose out on the decent MainConcept acceleration I get with my Fermi Quadro 2000.
Could I install both cards? Use the K5000 for my displays and have the Quadro in there just for Fermi support? Would Vegas see both of them and let me choose the Quadro 2000 when I want to render with MainConcept, but otherwise use the K5000 for better preview and Sony AVC renders?
Confused,
Steve

Vegas can see multiple GPUs. It can only use one, and it lets you select which one. That is in Video prefs and it sets the Vegas video engine OpenCL usage.
Exactly what the Mainconcept and/or Sony AVC encoders do with multiple GPUs I cannot say. Who knows how they select which GPU to use. Probably the primary display/GPU.
The only multi-GPU play did once was with Intel HD graphics and my AMD 7950. The HD graphics giving access to Quicksync for encoding in Sony AVC.

Thanks Norm;
Yea, I am willing to pick and choose in Vegas and put up with having to restart when I want to render MainConcept with the Quadro 2000.
I’m curious about this, though:
[Norman Black] ” The HD graphics giving access to Quicksync for encoding in Sony AVC”
I’m very ignorant of the Intel Quicksync option. I had thought that was something dependent on the motherboard, but what you wrote makes me think it is a capability of the graphics card?
Help,
Steve

Intel Quicksync is implemented in Intel CPUs which have integrated graphics. Basically just about any 2 or 4 core Sandy Bridge, Ivy Bridge or Haswell (what i have, 4770 to be exact). Quikcsync is a function implemented in the Intel GPU.
You have to go through some hoops to get it available without a monitor attached and your video card as your main GPU, but it can be done.

Thanks for the review…Mr.Stephen Crye.I am planning to buy QUADRO card again.

“Could I install both cards?”
You can install as many GPU cards as your motherboard supports. As said before, Vegas will only use the one you select in preferences.
But, an anecdotal caution – don’t mix GPU brands. More specifically, don’t mix drivers. If all your GPU cards are nVidia, then you only need one copy of the nVidia driver. No opportunity for confusion.

Can you explain the “red car benchmark”? Where can I download it to test my system? Thanks -

You can download the benchmark project here.

Hi Jerry;
The benchmark was actually written for SVP11, but of course it can be used with SVP12.
When I first discovered it last month I was very happy – of course it leads to all kinds of questions and confusion, but I have learned a lot since then!

And that’s using Kepler in OpenCL mode. So that also suggests that OpenCL, even if it’s not optimized on Kepler, certainly isn’t broken.
Having played and looked at this after your earlier posts, it was pretty clear to me that the MainConcept CODEC has an enumerated list of known devices it will use with OpenCL, and it’ll ignore all others. My guess was they they did the same thing with CUDA… you pretty much confirmed that here.

OpenCL in general is not broken…
CUDA in general is not broken…Mainconcept is the “broken” one.
