| What Danny says is correct: After Effects will use all of the CUDA cores of all of the cards installed, as long as they use the same CUDA compute level (essentially a CUDA architecture version number). As has also been mentioned, there's another caveat regarding VRAM and multiple cards: the GPU-accelerated ray-traced 3D renderer will use all of the VRAM of the installed cards... except that it will treat every card in the system as if it has the amount of VRAM of the least card in the system. E.g., if you have a 1GB card and a 4GB card, After Effects will use 1+1=2GB total. This is not true for Premiere Pro, which only sees and uses the CUDA cores and VRAM on one card at a time. ________________________________________ From: After Effects Mail List [AE-List@media-motion.tv] On Behalf Of Teddy Gage [teddygage@gmail.com] Sent: Friday, May 25, 2012 10:09 AM To: After Effects Mail List Subject: Re: [AE] Best GFX card for AE/PP interesting... really? I had thought that was only with a Quadro / GT series combo, not SLI or dual-head cards. Todd could you clear that up? Is the same true for premiere? If so, maybe I will put both the 580 and 680 in the same machine... that would be something.

Like in an SLI setup, AE / PP can't use the second onboard card, even though it's a single unit On Fri, May 25, 2012 at 12:50 PM, Rendernyc <rendernyc@gmail.com<mailto:rendernyc@gmail.com>> wrote: For AE I would think the most performance u will get at that price is the 590gtx which has 4x the cuda cores and 3GB ram More cores means faster rendering and then the more ram on the card will help out with larger evironment maps The q4000 will be much slower The 590 is basically 2 580s on one board. Depending on your system There's also the gtx480 and 580 where can install multiple cards that AE will use On May 25, 2012, at 12:39 PM, Rick <a_pmb_fan@yahoo.com<mailto:a_pmb_fan@yahoo.com>> wrote: Engineering is taking my Quadro FX1800 out of my computer. It is on the lower end of CUDA enabled cards but does help. I put up a fight until my boss said I had a $1000.00 limit to get whatever card I want to replace it. I will be upgrading from CS4 Production Premium to Creative Cloud along with upgrading BCC7 AE to 8 and getting the card, hopefully all today. What is the best card I can get for that price? So far I've seen the Quadro 4000 for either $80 at a never before heard of place or $700 from NewEgg. http://www.newegg.com/Product/Product.aspx?Item=N82E16814133324 z600 8core 2.13Ghz 16GBs ram Windows 7 Pro Thanks, Rick Emery www.rickemery.com<http://www.rickemery.com> -- Animator & Editor www.teddygage.com<http://www.teddygage.com> Brooklyn -- danny princz exposedideas.com<http://exposedideas.com> -- Animator & Editor www.teddygage.com<http://www.teddygage.com> Brooklyn |
