But NVIDIA's consumer oriented cards have very slow double precision processing, something like 1/16 the processing speed of single precision. And they even artifically hobbled the DP performance of the GTX 780, which is otherwise a slightly cut down Titan (i.e. big kepler). All of AMD's 79XX cards (and its rebranded brethren the 280X card), and the new 290X card have 1/4 DP performance. I've consistently bought AMD Radeon cards for my OpenCL applications because their $300 cards are almost as fast as NVIDIA's $1000 card, and in some cases faster, for DP calculations.
