oh dear...
A recent review I carried out to purchase hardware for Molecular dynamics, saw us decide that Nvidia was GPU of choice - the AMD hardware may be better (published cash of 5TFlops DP Linpack , for example), but their software is sadly lacking.
Nvidia pitched in some cash I think to cuda-ise gromacs, and now it *screams* on $500 graphics cards - oh , because we can use SP and simply accumulate in DP.
Then we come to CPU's and Intel is inside of so many HPC machines (probably as accelerator, but hey) and the new Knights Landing is looking rather cool. Ok only 3 TFlops (DP they say) but the architecture is recompile and go.
Intel realeased the E5-2697(?) and I saw a Linpack number of 700GF - that is impressive if true. Though knowing Intel it will be 3x anything AMD could put together - only they haven't.
If AMD could get the Radeon to be cheetah not an albatross, perhaps there would be some competition in the industry. As it is finding benchmarks is nigh on impossible...
We need competition to ensure the future is on time...!
