It isn't just the speed factor which is significant here. There's also the single precision / double precision question, which means that some projects can run on some, but not all, GPUs of ostensibly the same resource class (as currently defined), and the ongoing issues caused by varying 'compute capability' within the NVidia range. This latter point is still leading to discussion at GPUGrid - and they should know a thing or two on this subject - about issuing different app_version tasks to multiple disparate CUDA cards within a single host. As I understand it, this would not be possible whilst all GPU devices (from the same manufacturing stable) are treated as being in the same resource characteristic - another potential reason for counting them separately.
