yes, Open-CL is AMD's turf... bisan Nvidia supports Open-CL too... they just can't beat AMD on this field...
scientific and engineering computation is still in Nvidia's turf though... and my statement is true for the Tesla... AMD don't have offerings for this target market... or if they have, it can't beat the Tesla... we just don't know since we are not in that crowd who uses GPUs in scientific jobs... except, some of us here are in the Design works... like nila dha sa Lear (Design), Timex (Design), Fairchild (PTG)... mention lang ko'g tulo ka company sa mepz na nag gamit ug mga work stations... naka Quadro ang GPU sa gamit nila... but some unit also used FirePro too... but definitely, not Tesla GPUs...
maong sa akoang unang post, gi post gyud nako na kaning super-computer performance, para ra ni sa pang puno sa kaban... its not applicable to us since most of us here are gamers... some us here use their rigs for business like 3D rendering, designing, photo/video editing... in w/c, a desktop PC is capable to do...
