Sure but Radeon cards are not HPC accelerators. A modest 7800XT for example, which would be a great card for SD, has 76 TFlops@FP16, 37TF@FP32 and 1.16TF@FP64.

Sure but Radeon cards are not HPC accelerators. A modest 7800XT for example, which would be a great card for SD, has 76 TFlops@FP16, 37TF@FP32 and 1.16TF@FP64. Keeping all those FPUs busy is another problem and not easy, but in cases where it can be done FP32 is clearly desirable.
