Is sse3 required for ATI CAL support?

(1/2) > >>

BeemerBiker:
About midway down here the ATIStream SDK states that SSE 3.x is required.  Is that requirement for the SDK only or for applications developed by the SDK?  For example, the HD 4670 is an AGP card supported by the SDK, and can fit in an old dual XEON mombo I got, but the XEON's are the Gallatin seriies and although very good, do not have SSE3.

I noticed that the optimized SETI ATI app is SSE3 and this provoked my question.

Thanks for looking.

[EDIT] - fixed typo where I had 5670

Where did you find an AGP version of the HD5670 ? Mine has PEG.

That link leads to a HD4670, instead. But from AMD dev forum i now that AGP versions are not working with the stream SDK.

A CPU with SSE3 or better is needed, indeed.

Raistmer:
Not sure that SSE3 needed for GPU version. It required for OpenCL CPU build cause vector operations mapped to corresponding SSE instruction perhaps.
