When I run tegrastats on the AGX Orin devkit, I notice that it reports data for 2 GPUs. As per the specifications, it seems that there is only one GPU. Could you please clarify what G3RD and G3RD2 refer to here?
This is expected. Orin iGPU contains two GPCs. Each GPCs contain their frequency controller. So 2 nodes correspond to those 2 controllers. You can calculate the average loading by checking the values.
