    Hello.

    I have a mobility HD-4670 under Win7 x64.
    The card supports and works with OpenCL programs (but not all of them).

    As per GPU Caps Viewer, the card supports OpenCL profile 1.0.

    Can I upgrade it to OpenCL 1.1 either with a driver (I'm on 11.6b now) or the AMD Stream SDK 2.4?
    Or is the restriction based on the card's hardware capabilities and there's nothing I can do about it?

    Thanks.

    openCL is tied into the directX version of the card. 4670 = directX 10, so openCL 1.0


    if it was a DX11 card, it'd support more, for example.

    Thanks for clarifying this.

    It makes some sort of sense if you look at the respective release number (OCL 1.0=DX 10, OCL 1.1=DX 11) though I doubt that's what they had in mind.
