Unfortunately the only available app using CUDA is the Badaboom piece o' crap. Compared to x264 encoding jobs I do w/MeGUI+AVISynth they looks nearly as bad as DVD.

To see any real kinds of number comparisons we need same-settings on the encode and after that image quality (blocking, artifacting, color-loss etc.) comparisons.

I see, Fast because its crap ,Nvidia can be tricky.

....NVIDIA didn't make the program

It is still much faster than quad core cpus

This is all I could find, all though it isn't a great true comparison http://www.anandtech.com/video/showdoc.aspx?i=3374

Try reading a little more then the first sentence.

I gave their trial Badaboom a go and the output I got was nearly as bad as DVD (compared to the outputs I get from my x264 profiles that's REALLY bad), it was not meant for high-quality encodes that much is obvious. "Maybe" their pro version will be better and give the options one would expect w/a 264 encoder maybe not. As such we've seen no information other then the "feature" list on their website which includes AVCHD and the ability to decode/encode 1080p, whoopdeedoo.

Their current trial/consumer version is for noobs that don't care about quality encoding of HD content.

If you want to see a nice extensive benchmark of a multitude of CPU types check out: http://www.techarp.com/showarticle.aspx?artno=442


Believe me if there was another CUDA-enabled 264 encoder out there I would be giving it a try, but at this time there isn't and that is highly unfortunate. There was some initial effort early-on w/x264 to release a CUDA build, but it was abandoned. As such the new thing will be FPGA-based processing, hopefully such PCI-e cards will be available shortly in the $200-$400 dollar range and should provide much better encode speeds then even CUDA can push.

Sorry man, I felt really let down with this product, IMHO it's the worst possible kind of app to promote encoding via CUDA.

I did some tests in my quad vs my 8800GTX.

Results were disappointing:

Badaboom wasn't really meant to compare to any software encoders yet, the only profile it has right now is a baseline profile. Like walterman's tests show, the cpu can encode just as fast when using the most generic of settings. It's still too early to make a real comparison.
