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.
you can figure it out through:
I donot have 6990 handy to check. but a quick search in wikipedia shows it supports DP.
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.
