FPS / watt numbers for Xavier

Hello there,

Is tegrastats the right utility to regenerate MODULE PERFORMANCE / watt numbers mentioned at

https://developer.nvidia.com/embedded/jetson-agx-xavier-dl-inference-benchmarks ?

Is it like average of power numbers shown by tegrastats(at 1 sec sampling) while having all the 10,000 iterations of trtexec?
Kindly suggest.

( I have this doubt because, tegrastats runs at the interval of 1 second. And some models like MobilenetV1 has latency in the order of lesser than a milisecond for latest jetpack 4.3dp.
I am aware that power values can be tapped at higher sampling rate by using sysfs nodes. )

Hi
The --interval can set the sample rate as milliseconds

Thanks for the answer! I totally forgot to check --help. I assumed its in seconds because by default tegrastats runs with --interval = 1000.

Can you please answer the second question, “Is it like average of power numbers shown by tegrastats(at what sampling rate?) while having all the 10,000 iterations of trtexec?”

Also, is there any way to print timestamps at which tegrastats is taking measurements?

Thanks in advance.

The --interval is the sample rate. Like CPU loading is read the /proc/loadavg.
