| Danny, what can you tell us about your test? I'd be curious to see results for two different tests: one with an animated environment layer and one with a static environment layer. The animated environment layer will tax the bandwidth to the VRAM, which can be the bottleneck rather than CUDA cores in some real-world uses. ________________________________________ From: After Effects Mail List [AE-List@media-motion.tv] On Behalf Of rendernyc [rendernyc@gmail.com] Sent: Monday, June 04, 2012 12:00 PM To: After Effects Mail List Subject: Re: [AE] [OT] Benchmarking AE CUDA on nVidia GTX 580 vs. GTX 680 - SHOCKING RESULTS the 590 is 2 580s on one card. so it should be way faster than a 580 havent tested any multi card setups yet but am interested in seeing that. i would have thought the 590 would be much faster than it was in this test On Mon, Jun 4, 2012 at 2:47 PM, Andrew Embury <aembury@gmail.com<mailto:aembury@gmail.com>> wrote: Why is the 590 beating everyone else out? Could it be just a software support issue? If that's the case, should I wait for the 680 to catch up or just splurge on the 590? Thanks guys for the time and patience.

I'm looking at building my new PC for the sole purpose of AE/ C4D work and I'm curious to know if you have anything more to report between the GTX 680 and the GTX 580.

From: After Effects Mail List [mailto:AE-List@media-motion.tv<mailto:AE-List@media-motion.tv>] On Behalf Of Teddy Gage Sent: 26May2012 11:50 To: After Effects Mail List Subject: [AE] [OT] Benchmarking AE CUDA on nVidia GTX 580 vs. GTX 680 - SHOCKING RESULTS Well, shocking if you care about this sort of thing. So after some struggles getting the GTX 680 to work with AE CS6 11.0.1 I finally got it working. How would the 3 GB VRAM GTX 580, with 500 CUDA cores stack up to the brand new 2 GB VRAM GTX 680 with 1,500 CUDA cores? Would it be worth upgrading if you already owned a 580? Would the extra 1 GB VRAM make a difference for the older card? Well I came up with a benchmark (228K) available HERE<http://www.teddygage.com/AEBENCHCS6/> that maxes out the GPU and tests your CUDA processing ability. You will need about 900 MB local space for the output and the new 11.0.1 patch (probably). Now a lot of figures are at play here but with the project using 100% GPU and 25% CPU I think it's a decent bench for comparing graphics cards. Here are the results: GTX 680 (2GB) = 6 min. 11 sec to render GTX 680 (2GB) (overclocked) = 5 min. 52 s GTX 580 (3GB) = 5 min. 42 s So the GTX 580 with 3GB VRAM is faster. Now it's hard to say whether that's because the architecture is more compute-friendly, or the extra GB of VRAM makes that much of a difference. Considering I got the 580 for about $415 shipped used on eBay, I'd say for now nobody needs to rush out and buy a 680. It's performance is nearly as good, and great if you are focusing on games, but not for purely compute / cuda / mercury in CS6 I would love to hear some results on a 4GB 680, a 590 or a 690, let me know TG -- Animator & Editor www.teddygage.com<http://www.teddygage.com> Brooklyn -- danny princz exposedideas.com<http://exposedideas.com> -- danny princz exposedideas.com<http://exposedideas.com> |
