The 4670 offers a subset of OpenCL 1.1 only on Snow Leopard where the 
missing functionality is emulated by Apple's OpenCL software layer.
And it does *NOT* support double precision floats (only 32 bit single 
precision) as this is not even part of the OpenCL 1.1 specification, 
just a vendor specific additional feature and as such isn't even part of 
Apple's OpenCL implementation. At least when I last time checked but 
this might change in the future.

But I was assuming you are using Windows anyway where the 4xxx series 
together with the Catalyst drivers offers *NO* support for OpenCL at 
all. And the same is valid for Linux.
