A Tsunami of Improvement?

CUDA-Enabled Apps: Measuing Mainstream GPU Performance
By

A long-time favorite tool among transcoders is the Tsunami MPEG Encoder, or TMPGEnc, now owned by Pegasys in Japan. Within the video community, TMPGEnc is considered one of the highest quality transcoders available, although not necessarily one of the fastest. We used TMPGEnc 4.0 Xpress with a 15-second, 1440x1080 clip supplied by Pegasys.

Unlike some other transcoders, TMPGEnc only uses CUDA for effects acceleration. The encoding process itself is currently not GPU-accelerated.  You’re only going to see benefits from CUDA here when the transcode process involves effects/filters such as noise reduction, sharpening, and so on. This is why you need to read the fine print before investing in acceleration technologies and the apps that use them. Make sure that not only the application you’ve picked but also the functions that you need from that application will deliver what you expect.

    Good article. Very interesting. Pity you can't spell measuRing! :p

    Great article!! I ran Seti@home on my GPU alone for quite a while. Although it is not a powerfull card in the slightest, a 8500GT, it still completed workunits faster than my CPU could (even more using the optimized apps). However, it has damaged my system as there are a few problems with running it. The heat generated from running the card processors at full all the time is a real pain. The fans on the lower end cards simply are not good enough to cool the cards, even if manually upping the fanspeed to 100% with RivaTuner. Secondly, if you allow it to use your GPU when you are using the computer, total utter graphic lagg even when reading webpages.
    Overall, it is a good technology, still has a few bugs which need to be solved and also the lack of support for ATI cards fustrates me. I am an avid BOINC user, I crunch Rosetta@home on all of my CPU's however I now let the GPU's run idle because the problems it causes. I will probably re-enable GPU usage if I upgrade my card in the future.

    Cuda will never be suported by ati,its a Nvidia thing.
    Also an 8500gt is just not powerfull enough for cuda+multitasking a pc.IMO. Hell thats a under $50.00 gpu.

    Lumpy, even an 8500 would be advantageous considering the speed hike..what's so bad about the CPU getting extra help from something that would otherwise just be displaying raster graphics or waiting for Crysis to fire up?

    AMD now has a grave challenge at its feet.


    But look at AMD's platform solutions: highly integrated, highly efficient..can't say the same for Intel. I'd rather wait a bit longer for the software to be stable rather than use the GPGPU equivalent of an Intel GMA chipset trying to run GTA IV..

    OpenCL is AMD's answer
