2 GPU (285) – will the render be faster or only stereo render
I need to speed up final render and interested if I should use redrocket or I could install two GPU ? Render is not stereo, r3d 2k.

Rocket for sure

The red rocket will help with the r3d debayer, but I don’t believe it will help with dpx to dpx.
2 285 should speed up the dpx render. I think..
You bring up a great point. Will 2 285’s help if your doing regular 2k dpx grading??

Yes i/o is huge.. My question is with very fast sustained i/o.. Fibre or solid state.
Will the additional gpu power speed up renders or the same session with the same set up.NOTE: The comments above are strictly mine, and may not necessarily

I bet you get more nodes per shot? Not only 2 streams but lets say you have
one 2k stream and you can put about 30 nodes on that one.So in theory lets say you use 10 nodes and render out you should get really huge speed.
To go really mad think about 4x 285 with two expanders.But this is just my theory. BM could give some direction here 🙂

Hi all, its all about balance and the work you do. You can put in three GPU’s for fast image processing, but if you have one disk, that’s going to be the limitation. Conversely, one GPU may not give you 10 nodes of 2K but the fibre channel Aurora from Rorke Data will definately will give you the 2K bandwidth with plenty to spare. If you have r3d, use a Red Rocket for full debayer at 2K in real time. Stereo r3d requires two Rockets. If you have a lot of QT files, CPU decoding and encoding speed will benefit from faster and more cores.
For those looking at tuning for high performance, consider one drive array as the source and another as the render destination. In this config, your drive controller can stick to one task. We know of Resolve colorists getting better than 100fps for SD dailies renders and at BMD post we render 2K faster than real time so clearly it’s not an application limitation. It’s just about configuring the system to meet your budget and operational needs.

I’ve made a test today – put geforce 480 alone (with 2 displays attached) into a hackintosh and got twice as fast debayer vs my 2008 Mac Pro with 285 and gt120.

Of course your Hackingtosh has a much faster CPU, right ?
480 does not debayer a thing, but its grading performance should be lovely too.A slice of color…

No, CPU is slower. I’ve tested it in many ways. Clipfinder is slower on my h-osh.

Hi Mikhail,
Can you share some specs on your H-sh system? (MB-CPU-Mem-Pci-e)
I have 2009 2.26 gt120/gtx285 and I’m not impressed with the perfomance so far.
