Cuda

[1337]

Mostly curious... a question to Geforce 8+ owners. How have you found Cuda technology? Any practical usage and/or thoughts?

Cheers.

For a "typical" user (that isn't doing massive number crunching operations), the only practical usage for CUDA that I know of is CoreAVC, an h.264 decoder that can use CUDA to assist in decoding h.264 video and reduce CPU usage.

In most cases, DXVA does the same thing. But DXVA is a fixed hardware path with some specific requirements, and occasionally you will encounter the odd h.264 file that cannot be decoded with DXVA.

CoreAVC, on the other hand, is a software decoder that is able to take advantage of CUDA to do some of the decoding, so it can handle pretty much everything you throw at it. Plus you can do some more post-processing with the output video.

Some more detail from the CoreAVC site: https://customers.corecodec.com/knowled ... -DXVA.html

photoshop and premiere pro utilize cuda, and in the case of the latter, you can get better quality with it, vs. just the cpu.

Found out one more: MediaCoder, a popular alternative to Handbrake for transcoding to iPods/PSPs/anything else, can use CUDA acceleration for transcoding. My GT240 can transcode to iPad settings at about 1/3 of realtime, vs. about 85% of realtime on CPU only (Phenom II X3). Don't notice any quality differences either.

Highly recommend Freemake Video Converter. It has CUDA support for MP4 encoding and I found it far easier to use than Mediacoder.

IIRC it shouldn't be so.
