In my short search, I didn't see evidence that either package has run-time dispatch based on the processor type. I don't see "cpuid" used in the scipy code base, and the only intrinsic I found is specifically in a MS Windows #ifdef. Numpy doesn't use cpuid. It does have compile-time options for intrinsics, but not run-time.
