Nettet5. des. 2024 · It looks like even WMMA 16x16x16 INT8 mode is nearly as fast as 8x32x16 INT8 mode, ie. 59 clock cycles for the former and 56 clock cycles for the latter. Based on the values given, 16x16x16 INT8 mode at 59 clock cycles compared to 16x16x16 FP16 (with FP32 accumulate) at 99 clock cycles, makes the INT8 mode around 68% faster … Nettet6. aug. 2024 · As I see, benchmark app still shows FP32 precision for your quanatized model.
