Nvidia GTX480/FX5800 + Adobe Mercury Playback Engine
Bit of a mixed one this. Nvidia are just about to release their new GTX 480 card which I'm guessing will be supported by Adobe but does anyone know how this would compare to the Quadro FX cards?

Scan.co.uk: VCQFX5800G-PCIE-PB - 4GB NVIDIA Quadro FX 5800, PCI-E 2.0 (x16), GDDR3, SLi, DisplayPort/ 2xDL DVI-I/ Stereo Port, Retail So the GTX has more CUDA cores and more GB/Sec so would it be faster for Adobe Pr/Ae use in mind? I must be missing something as the GTX is £450 and the FX is £2500 Anyone have any thoughts on this? |
The FX 5800 is probably the same GPU as the GTX 285, with 240 SPs or "Cuda" Cores. They charge a large premium (4x and more) from the Quadro over the Geforce equivalent with driver certification support, larger memory frame buffer, and other requirements from professional/workstation requirements (3D, CAD, and more). I'm also looking at the GTX 470 or GTX 480.

I'd love to see some CS5 benchmarks with these cards. C'mon Adobe!!

My understanding is that only the Quadro cards will do more than three layers of realtime with the Mercury Playback Engine.
So if you think you'll be doing that often, there's your answer. |
yeah but how does one of the new 480s compare the last year quadros?
|
Maybe the Geforce models (GTX285, GTX 470 and GTX480) will be software restricted to three video layers, even though they have more streaming processors or cuda cores than their sister $1k-$2k quadros.

I seriously doubt that. I think we need to look at it this way. In the early stages of course Adobe is going to use the heaviest hitters that Nvida offers. Now with the fermi coming out the consumer cards will have as much punch if not more than the older pro cards. So in the short term ( a year or so ) we'll really have to pay for performance but as cards drop I think we'll be able to get $200 to $300 cards to do what we need.

David, yes, I'm not sure why Adobe would care what Nvidia card you would buy, but seemingly the slower Quadros will outperform the newer Fermi based GTX Geforces. Per Mark Morreau's comment, according to Nvidia's website, it says Quote:
So either the Quadro's additional frame buffer memory, driver optimizations, or something else (artificial barrier??) is there to make the Quadro "outperform" its sister Geforce cards with additional video layer support, even though the Fermi based GPUs like the GTX 470 and GTX 480 (and even the GT200 based GTX 285) have more power than the older and pricier GT200 based Quadros (CX, FX 5800, etc.). |
One additional thing to look for in a consumer model is how much RAM the video card has. That could be a possible future limitation. I have a 275 GTX, but it has 1792 MB of RAM, which is more than the reference design requires.
I can't say what impact this will have in CS5, but I do know that video software like the 2.5D tracker Mocha, that make use of the video card RAM to store textures, benefits greatly from having more RAM. |

It seems Nvidia has got into bed with Adobe. Not offering support for the GTX 480 until Q3, limiting the consumer cards to 3 layered effects. I guess they have done it not to pee off the Quadro owners. |
Hi
I ordered the FX 4800 14 days ago - now I orderd a GTX480 instead - newer , faster and cheaper. No support for mercury yet - but I can wait and I never do more than 3 layers of video. |
Plus I think the 3 layers limit is for effects you can still have more than 3 layers just not with effects in RT. ie a 4 camera multicam switch.
|
Just a word of warning: The GTX 480 runs REALLY hot. If the fan is left at automatic, it's running temperature is 95C.
Plus, it's also fairly noisy when it comes to it's fan. Newer drivers from Nvidia have also suffered from stability issues, making TDR errors very frequently. |
