Difference between Radeon 5870 and Quadro 4000 and just the Radeon 5870
by Arty Black on Aug 24, 2011 at 12:36:59 pm

Hello All,

My Resolve system runs on a Mac Pro 12 core 2.93 GHz with 32 GB RAM and a Radeon 5870 in slot one and Quadro 4000 in slot two.

Since the system is running sometimes very loud especially in the beginning after startup, I had the Quadro removed for the last week because I didn't need to run Resolve. The quiet Mac Pro is a dream ...

Today I needed to grade a shot quickly in Resolve and didn't bother to put the Quadro back in again. To my surprise the system is running with almost the same speed.

Is there a possibility to check if the Quadro is being correctly utilized besides the startup warning. I know about the GPU meter but it's somehow not giving that much feedback.

Thank you!
Arty

Hmmm...wait a minute...
Its very loud from startup ?
That indicates OSX cant control the card.
I had the issue with the 470 on Snow Leopard before I spliced in the Quadro drivers.

The only way to find out, no wait, there is two, is to run either the Resolve benchmark I designed or just the simple Cuda-Z app.
Here the benchmark, you need to replace the file in question with yours, found in the installer.

And here the CUDA test thing :
http://sourceforge.net/projects/cuda-z/files/cuda-z/Beta/CUDA-Z-0.6.133-SVN...
This one should show around 600 GFlops or more for the Q4000
GT 120 = 88
GTX285 = 600
GTX470 = 1100
GTX570 = 1300

Resolve should run just fine with a node or two on the Radeon I guess.
But try to put some load on it, then the GTX cards show their muscles.

I have installed Resolve and a Quadro 4000 GPU also (with a GT120 as the main card) . I have not started to use Resolve yet but have noticed when I do run it that it is noisy. When I did do a little experimenting with grading I did think to myself "this is pretty slow".

Resolve does say the Quadro is running as a GPU and everything is installed to Blackmagic's specs.

I downloaded the CUDA-Z but don't really know what the numbers are telling me. This is what I'm getting without Resolve running.

Single-precision Float 482 Gflop/s
Double-precision Float 185 Gflop/s
32-bit Interer 242 Giop/s
24-bit Interer 242 Giop/s

For the GT120

Single-precision Float 88 Gflop/s
Double-precision Float NOT SUPPORTED Gflop/s
32-bit Interer 17 Giop/s
24-bit Interer 88 Giop/s

Well, the good thing is, it seems to work.
And yes, thats what you seem to get from a Q4000 in performance.

If it works it will make noize. But not in the beginning. When under heavy load
gpu will heat up and the the cooling comes in. this is normal when all works.

Sascha thank you for the test! Will run it over the weekend ...

Concerning the noise, this is really strange, when I start up the Mac Pro the expansion slot fan is going up to 1900 RPM. (normal without Q4000 it's around 800 RPM). When I start to use the GPU but just when I use the GPU the expansion slot fan goes back to normal behavior.

So my startup with the Q4000 looks like the following: I boot up and start Premiere (Mercury enabled) play a native RED file with some effects applied to it and voila the fan goes down to it's normal state around 800 RPM.

One would think that the fan is going crazy when the card is used most but this is not the case. It needs to be used. There was a thread to this in the NVIDIA forums where other people reported the same behavior. I reckon it has to do with the NVIDIA drivers ...

The system is running on 10.6.8 with the latest drivers for the Q4000 (general and Cuda).

I really enjoy working with my system when it's quiet. It works with the Q4000 but the procedure is to get quiet is really annoying.

Tips are very welcome.

Thank you!

Hi Arty,

Can you tell me how you setup the ATI 5870 and the Quadro 4000? I currently have an ATI 5770 in slot 1 and the Quadro 4000 in slot 2. How did you get around the power supply issues? I have an ATI 5870 which I want to put in but can only find information by using an external power supply to run the 5870.

Thanks
Kelly

Hi Kelly,

It's pretty straight forward and works like a charm. You get a Y 6 pin splitter cable, like this one:
http://www.amazon.com/CB-6M-68F2-6-pin-PCI--Dual-Cable/dp/B005GWFZ8Y/ref=sr...

So you have the two needed for 5870 and one extra for the Quadro 4000.

This setup works really well. Just the noise before you start to use the Quadro is annoying. It's such a strange thing that you have to use the card heavily before the fan turns down. Probably a driver issue.

Besides that everything works really well. I did already some stress test, having the Mac Pro running constantly for more than 72 hours and no sign of overheating.

Hope that helps!

All the best.
A

Hi Arty,

Finally got the cable and installed the 5870. Easy enough. But I don't have the heavy fan noise from the quadro. Probably is a driver issue. I have the latest on the quadro.

Thanks for the help
Kelly
