  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

GTX480 expectation ?

GTX480 (Fermi) is out now. Since CS5 is working on this beast support.

What is the expectation of this card as compare to GTX285 on R3D files ? Can we expect even more massive speed increment ?

Adobe ? Anyone ?

Thanks
 
You will definitely get a nice speed boost, but don't expect anything massive. The 480 is roughly 40% faster than GTX 285 in gaming applications. The 480s were expected to feature 512 cores and 750 MHz clock speeds. Sadly, they could only manage 480 cores and 700 MHz, which is significantly down on targets. I understand that Fermi is supposed to feature special GPU compute enhancements (especially dual precision performance), but most are disabled for the 480 card and will only feature in the Quadro and Tesla versions. So, don't expect a massive improvement. Plus, it isn't officially supported, and those who have forced its usage have reported instability. Over and above that, the GTX 480 is overpriced, a massive power hog and runs extremely hot. GTX 285 is the best option as of now, it seems, even though its ancient and obsolete.
 
I read some overheat problem with early GTX480, but not sure how it performs now and it draws a lot of power.

You are right GTX285 seems to be the best bet.

But 40% speed increment (gaming) is not bad you know.

Thanks
 
As usual no mac version>>>>>>>>>>>>>>>>
 
You can use the 480 today, with these steps:

Step 1. Go to the Premiere CS5 installation folder.
Step 2. Find the file "GPUSniffer.exe" and run it in a command prompt (cmd.exe). You should see something like that:
-----------------------------------------------------------------------------------------------------------------------------------
Device: 00000000001D4208 has video RAM(MB): 896
Device: 00000000001D4208 has video RAM(MB): 896
Vendor string: NVIDIA Corporation
Renderer string: GeForce GTX 295/PCI/SSE2
Version string: 3.0.0

OpenGL version as determined by Extensionator...
OpenGL Version 2.0
Supports shaders!
Supports BGRA -> BGRA Shader
Supports VUYA Shader -> BGRA
Supports UYVY/YUYV ->BGRA Shader
Supports YUV 4:2:0 -> BGRA Shader
Testing for CUDA support...
Found 2 devices supporting CUDA.
CUDA Device # 0 properties -
CUDA device details:
Name: GeForce GTX 295 Compute capability: 1.3
Total Video Memory: 877MB
CUDA Device # 1 properties -
CUDA device details:
Name: GeForce GTX 295 Compute capability: 1.3
Total Video Memory: 877MB
CUDA Device # 0 not choosen because it did not match the named list of cards
Completed shader test!
Internal return value: 7
---------------------------------------------------------------------------------------------------------------------------------------

If you look at the last line it says the CUDA device is not chosen because it's not in the named list of card. That's fine. Let's add it.

Step 3. Find the file: "cuda_supported_cards.txt" and edit it and add your card (take the name from the line: CUDA device details: Name: GeForce GTX 295 Compute capability: 1.3

So in my case the name to add is: GeForce GTX 295

Step 4. Save that file and we're almost ready.

Step 5. Go to your Nvidia Driver control panel (im using the latest 197.45) under "Manage 3D Settings", Click "Add" and browse to your Premiere CS5 install directory and select the executable file: "Adobe Premiere Pro.exe"

Step 6. In the field "multi-display/mixed-GPU acceleration" switch from "multiple display performance mode" to "compatibilty performance mode"

Step 7. That's it. Boot Premiere and go to your project setting / general and activate CUDA

480 will eventually be officially supported this year, but this should hold buyers over till then. Seems to be that CS5 cuda support is a locked system for quick compatibility with new cards, which means that cs5 cuda will not take advantage of specific strengths of any card. Compatibility seems to be determined by which card Adobe agrees with Nvidia to put on the list (and of course that they can guarantee compatibility with).

Should note that for more that three layers of video, cards can be 'authorized' to accelerate those extra layers, from what I've heard.
 
Most of the benchmarks I've seen show the GTX 480 to be a 20%-50% speed improvement over a GTX285. Here is an review with benchmarks I read a while ago: http://techreport.com/articles.x/18682/1 .

In my opinion it may not be worth waiting for unless you have no problem waiting and spending more. Keep in mind with PPro CUDA acceleration, GPU is only used for effects, how your R3D footage plays without effects applied is entirely based on your CPU and Storage Systems (In most cases, CPU will the primary bottleneck).

From my limited experience using CUDA in PPro, the difference between having CUDA and not is great but the difference between a $100 and $600 GeForce card may be barely noticeable in many practice. I could be wrong about this as I havent gone through a whole R3D project from import to edit to export in CS5 yet.

Absolutely not. The GTX 285 initially released at $400. Guess what the price is today? Yes, at least $350. The reason why it is a worthless card is that the much faster, quieter, cooler, DX11, and in every way better HD 5850 is $300. Even Nvidia's own GTX 470 is the same price.

The only reason, then, to buy a GTX 285, is for Adobe CS5. (You could use the hack... But users on Adobe forums have reported instability) If I were to wait, I would definitely wait for HD 5800 support rather than GTX 400.

Now, if the prices would have dropped to $200, it would make more sense, and your logic would prevail.
