Help me learn abrout GPU accelerated video decoding

[CrazyMike]

So recently I posted a thread asking about which CPU to go with for a build for a friend that is doing Video Editing. It was brought to my attention about GPU acceleration during post production. Since then I have been trying to learn more about it and how to impliment this into the build.

 

A few questions popped up that i can't find answers too:

 

1) Which programs offer GPU Accelleration? So far i can only find two; Sony Vegas 12 and Adobe CS6.

 

2) Is it correct to say that CUDA (Nvidia) is not as popular as OpenGL (AMD)? From what i can see, CUDA is only supported in Sony Vegas 12 but OpenGL is supported by both. I am not sure if I have it right that OpenGL refers to AMD cards.

 

3) Which cards are better for GPU Acceleration? From what I have read, people are saying that older cards for both CUDA and OpenGL are better at GPU Acceleration. BUT that only certain older cards support this. So how is a person to pick which is the best card for the dollar to help accelerate?

 

 

Hopefully someone can direct or help educated me on this. Even better if it will help educated someone else as well.

 

Thanks,

For number two, Both AMD and Nvidia cards support OpenGl

Any card can accelerate to do what ever you are doing, it just depends on the amount of power that you need.

I  would say all adobe creative apps support CUDA acceleration, but it is rumoured that it will also support openCL in the future.

Currently nVidia is the best route to go for GPU accelerated video encoding/decoding!

Well, the current Nvidia Kepler (GK 1XX) architecture is not very well optimised for compute operations.

AMD's GCN is much faster. However, only Nvidia cards support Cuda and OpenCL is supported by both.

It all depends on the software you do from day to day, so if the stuff you use does not support OpenCL, Nvidia is your only option.

Does anyone know what software allows for GPU Acceleration?

You are saying that all programs impliment this? And what do you mean by "Power"? Like wattage or how much acceleration do i need?

Not all programs implement this. By power I mean the graphical output the card can produce. Such as a GTX 660 TI can't run games as high as a FPS as a GTX 780 TI because the 780 has more processing power.

Ah thanks.

 

Graphical power isn't my main concern. I am just trying to understand which programs take advantage of GPU Acceleration along with which cards.

Any program can, you can also do it manually if needed.
