Do Photoshop/Illustrator use CUDA?

[Anchorman]

Is there any benefit when using the above programs, to have a cuda enabled card? And if so, which cards currently have this?

...And what exactly is it?!

I think all Nvidia gpus 8000 series and above have cuda.

However ATI cards will also work with Adobe software, they just wont have the cuda...

CUDA is a method of computing on the GPU (doesn't have to be a graphical/rendering computation) instead of the CPU - this is useful in cases where you can process a lot of data in parallel.

As a poor example if you have a plugin thats manipulating an image and looking up each pixel in an image and applying a filter the GPU can potentially process 100s of pixel in a single clock cycle whereas the CPU can only manage say 4 - granted the CPU is often running several times faster but its still quite a lot slower for this kind of processing. Plugins that can be accelerated via CUDA or another compute language running on a GPU will typically be massively faster at processing complex filters, etc.

The standard adobe stuff uses OpenGL rather than CUDA, so a lot of ATi and nVidia cards can use the acceleration.

CUDA is only used in Adobe Premiere. Photoshop uses a basic OpenGL implementation and will basically run on a GeForce 2.

Nvidia's marketing department have done a very good job of confusing just about everyone on this, it seems.

Photoshop can use CUDA plugins tho.

Open GL is used for hardware accelerated rendering and previewing mostly rather than for compute purposes.

I'd agree with that, I've seen them plug it as an nVidia feature quite a few times really, when it's definitely not.

This video, while by nVidia, doesn't actually make such claims, they just go through what the GPU acceleration features do in CS5.

OK, cheers for the info. So for general 2d image manipulation, there wouldn't be a massive difference (or do those plugins help basic functions too?).
