Actual Benchmarks on GTX 680’s in Resolve?
-
Oooo, would love to see some actual number comparisons between 680s vs 580s in Resolve. Was gonna buy three 580s today but I will hold off tell I hear your numbers.

You are on Windows?

Hi Rohit. Will be soon. Building a new workstation for Resolve and Motion Graphics…so trying to find the best balance in GPUs. You may not remember me but we met at the 2011 NAB. I had tons of technical questions trying to force an old 2007 Mac Pro to use Resolve. Needless to say I gave up. I will be building a new workstation for that purpose.

Very interested to hear more. Not too far back we tested the 680 in a windows resolve config and found it to be roughly on par to slightly behind the 580. So the AE results seemed to be in line with what I had seen then. Has there been any optimization in Resolve for the 680? Are you testing it on a PCIe3.0 system per chance?

I bought a “stock” new EVGA GTX570 2.5GB for use in a Mac Resolve. I had MacVidCards mod it with their firmware as it did not perform well prior to this. I replaced a GT120 + GTX285 combo… I use it as GUI + GPU as I wanted to get the PCI-e slot back. It’s at least as powerful as the 120/285 and I can render out larger frame sizes. I have been too busy to benchmark it.
GTX 570 is a great balance of GPU performance and system power draw. I’m actually running with a 2-1 power cable splitter too. It’s running in a 2010 12-core 2.66 Mac Pro. I use this machine for Resolve, AE, Symphony, Smoke & MC.
For Resolve I can get 24fps w/ 10-12 nodes and low NR at 1080p Pro Res. 4k Epic renders out at about 10fps at full quality (I think). DPX 4k renders out at about 200mb/s which is as fast as the storage usually likes to go.

So we have GTX680 drivers for OSX.
They are in 10.8 DP4 and we even have a way to move them from MBP 2012 install into Mac Pro and have some basic 680 functionality in 10.7.4.
I am in talks with a Hollywood area color facility who will be testing 680 against the Grand Poobah of 580s, the EVGA Classified 3Gb model.
Will keep you posted on results.
I would expect 680 drivers to mature in OSX in 60 days or so.
BTW, the CUDA-Z “Single Precision Float” number for 680 hovers between 1700 and 2000.
The 580 classified does same range but doesn’t break 2000 usually.
The OpenGl View numbers in 10.7.4 for 680 are below 580 by quite a bit.
I don’t think it is running full speed in OSX yet.

Would love to hear anything you have soon Rohit. Need to make a workstation purchase soon. Or maybe a heads up on either buying GTX 580 3GBs or GTX 680s? Thanks.
-
Based on our initial results, on both Windows and Linux, the 680s (Gigabyte OC version), and the 580s are both running with fairly similar performance.

Rohit, thanks for that clarification/update. Very helpful.
One question the overclocked 680 is that compared to an overclocked 580 or a stock 580?

Thanks Rohit, I appreciate the info. That has me intrigued now. I may stall and wait for the 4GB 680s. Only sad thing would be the lack of being able to run them on a hackintosh config. All windows, which is truly where I am probably going.
