    NVIDIA hops aboard GPGPU train

    ATI's got its Stream Computing technology for GPGPU stuff, and we all knew it wouldn't be long before NVIDIA came along with an equivalent.

    So here it is, NVIDIA's announced 'CUDA'. It stands for Compute Unified Device Architecture; lovely.

    PHP Code:
    $s = new signature();
    $s->sarcasm()->intellect()->font('Courier New')->display();

    Sounds like a good idea to me. There is no reason not to have the GPU pitch in
    for things like decoding and other tasks that it can be adapted to where 3D usage is practically 0.

    Very cool. Had been wondering when this sort of thing would become officially supported.
    Asus Z170 Pro Gaming. i5-6500. 16gig Ripjaw 2400. Samsung 950pro NMVe 250gig+ 1tb Intel 660p. GTX Titan. Corsair TX650M.

    1950XT | 500gig,320,200,160
    Plextor DVD burner | Yamaha CRW-F1 CD-drive
    Thermaltake Xaser 3 w 480W FSP | X-fi fatal1ty

    Things have moved on since I first joined...

    It'll be cool if it speeds up tasks like video encoding, or other processor intensive stuff. Although I wouldn't use it for much other than games....

    Do you think SLi systems benefit from having multiple processors? I'm curious.

    Doesn't the 8800 series have 128-bit FP precision?

    in MarketingSpeak(tm), sure

    it's 32 bit per color. RGBA makes 128 - but you can only do GPGPU maths with 32.

    there's also the question of IEEE-754
