Is it possible to overclock the GPU inside the TX2?

Hi

I am doing a benchmark between 2 EDGE devices: Google Coral and Jetson Tx2.

I have planned to overclock the TPU and GPU respectively.

So far I have overclocked the TPU, from 250MHz (STD) to 500 MHz (MAX). But I do not see any difference.
The “stress” test was doing inference 70000 times in a classification task (AI). I used 1 image, because I do not want to measure the latency between the CPU and TPU (the CPU does the image preprocessing). everything took around 2 hours.

I am going to overclock the GPU. I do not know if I will have BAD results as with the TPU. So, please any comments or suggestions are welcomed.

Here is the plot that I made. It displays the variation in temperature. Unfortunately it is the same for STD and MAX frequencies.

Hi,
Please refer to power management in development guide. After executing sudo nvpmodel -m 0 and sudo jetson_clocks, TX2 will run in max performance. You may check benchmark in this condition.
