GPU Max Clock rate is slow, only 72 MHz (0.07 GHz)


I install TX1 used the latest, and after installation, we found that the GPU Clock rate is very slow, see belows, is this normal?

Thanks for your feedback.
The information is incorrect and we will check this. GPU max clock rate should be 998MHz on TX1.

If you are interested in GPU MAX clock rate, please use tegrastate to get the information instead.
