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.
