WebMar 29, 2024 · I tested the performance of float cufft and FP 16 CUFFT on Quadro Gp100. But the result shows that time consumption of float cufft is a little lower than FP16 CUFFT. Since the computation capability of Gp100 is 6.0, the result makes me really confused. Can you tell me why it is like this ?
