We want to know the compute performance of tx2 GPU theoretically.But there are some pieces of information confused us.
1.According to https://en.wikipedia.org/wiki/Tegra#Devices_6. We know that tx2 gpu maximum working freqency is 1465 MHz and the FP16 compute capability is 1500 GFLOPS 2.According to Jetson_TX2_TX2i_Module_DataSheet_v01.pdf The GPU maximum operating frequency is 1.12GHZ.We assume the FP16 compute capability is: SMs*FP16 unit pre SM*2*clock rate = 2*256*2*1.12=1146.88 GFLOPS 3.cat /sys/devices/17000000.gp10b/devfreq/17000000.gp10b/available_frequencies We found the maximum clock freq could be 1300500000,but we can only set 1122000000 as the maxinum freq, the 1300500000 is a invalid argument. Now we have the following questions: Q1:Is the maximum frequency of TX2 GPU on Wiki wrong? Q2:Is the arithmetic SMs*FP16 unit pre SM*2*clock rate = 2*256*2*1.12=1146.88 GFLOPS right? Q3:Why we couldn't set 1300500000 as GPU frequency ?
