I may be mistaken, it's my understanding that the video game cards are designed to be faster at the expense of accuracy, whereas the scientific computing cards are designed to have better accuracy at the expense of speed.
- maximilian 16y agoAre the game cards not following IEEE floating point spec? I really should ask this on the nvidia cuda forums to get a really good answer. Edit: Wikipedia says that the Tesla cards have 4X higher double precision performance than the game cards, so that could be the explanation.
