Double Precision Support for MD Radeontm HD 6990M ?

Does the AMD Radeon™ HD 6990M support double precision?

It would be  great if all vendors can provide  a  list of OpenCL  Device Extensions for new devices.  Then we can see  if they support double precision and atomics, ....

 Does this device support  OpenCL Extensions  cl_khr_fp64 and/or cl_amd_fp64?

 

The link  below claims 1.6 Terra FLOPS (single precision)  which is impressive. But come on, making a supercomputer like claims without supercomputer precision undermines AMD cred.

To clarify and elaborate the 6990M is  mobile chip, so you can't just plug it in. You would need to purchase a complete latop that incorporates it.

My other point is should Wikipedia be the authorative  source for a Vendor OpenCL Device extensions? As much as we love Wikipedia, I would hope not. Vendors should take ownership and be explicit and transparent about what  their device supports.
