CUDA-Enabled Apps: Measuring Mainstream GPU Performance

Remember in Minority Report how Tom Cruise does his computing by gesturing on a transparent display? The UI concept is so captivating that it’s since been copied in a host of other venues, including TV commercials. Well, imagine a conventional video editor meeting a Minority Report UI then getting filtered through a Nintendo 64. That’s Super LoiLoScope, and “MARS” is the code-name for its new, CUDA-enabled version. No, MARS (as I’ll refer to it for brevity) isn’t Adobe Premiere. It’s not even Premiere Elements. Heck, it’s not even PowerDirector 7. But it is wickedly simple to use once you wrap your head around its hypergraphical, drag-and-drop-o-rama design. Better yet, it makes use of CUDA in H.264 encoding, decoding, and playback, making this one of the most thorough CUDA implementations seen yet.

Nvidia and LoiLo (the name of the company behing SuperLoiLoScope) set expectations very high with this application. The companies point out that while a quad-core CPU can compute at 100 GFLOPS, a 240-core GPU like the GTX 280 can nail 900 GFLOPS. As such, we should expect to see a significant encoding performance improvement with a GTX 280. Obviously, our results should be lower with the 9600 GT and 9800 GTX, but on a percentage improvement basis, we could reasonably expect to leave TMPGEnc in the dust thanks to the broader CUDA implementation.
