Hi,

I’m trying to benchmark some networks on AGX Orin Nano 4gb in emulation mode.
I recorded tegrastats log during the trtexec benchmarking process.
I have observed that the “VIN_SYS_5V0” power rail is consuming around 4.3 W in 10W power mode.

Could you please explain the “VIN_SYS_5V0” power rail usage.

Thanks,
Sairam

VIN_SYS_5V0 is for DDR and IOs.

thanks for the response.

Could you please explain “VDDQ_VDD2_1V8AO” power rail is powering in . ?

Did you meet any issue on this? It is a module internal power rail for DDR.

nope, I’m trying to understand the Power rails. for FPS/Watt calculation

So the right FPS/Watt calculation would be FPS/ (vdd_cpu_cv + vdd_gpu_soc + VIN_SYS_5V0) right ?
