You can monitor how much the CPU, GPU and ANE are being utilized if you use the python tool asitop.
Basically just open a terminal and install using
pip3 install asitop
if pip3 isn’t linked then just use
pip install asitop
and then run using
sudo asitop
Here for example you can see that when I process a video from FHD to 4K using Video AI 3.1.2 that the GPU and ANE are almost fully being utilized, with the CPU still contributing quite a bit. Different models and encoding options will change the utilization, but this is the simplest way to monitor that. Below are two screenshots of my test right now.
