Nvidia TX2 GPU Memory and IO power consumption

Hi there!

I understand that, GPU on TX2 do not have their own memory instead it uses available system memory (8GB).

Is there any way to calculate memory power consumption for Memory Usage? Does calculating power based on VDD_DDR power rail under the : cat /sys/devices/3160000.i2c/i2c-0/0-0041/ will suffice? Is VDD_DDR power rail for “8 GB 128 bit LPDDR4 59.7 GB/s” ?

Also, I connect sensors at Ethernet port, what is the right way to calculate IO Power consumption? There are few options for IO devices power rail, VDD_IO_SYS, VDD_1V8_IO, or VDD_3V3_IO_SLP, which one should I use to calculate IO power?

Hi, you can use that to read info of VDD_DDR. And IO power rail of Ethernet chip is in module, not exposed to be measured.
