Referring to documents and forum posts, I found that the power consumption of NVENC can not be obtained on TX2 alone. Only the power consumption of VDD_SYS_SOC includes the power consumption of NVENC, so I can only get VDD_SYS_SOC to reflect the difference between NVENC power consumption when encoding H264 and h265.
I use the same real-time video source to encoding H264/H265, encoding for 3 minutes and 45 seconds, and then count the average power consumption:
In theory, the complexity of H265 encoding is more than four times that of H264. Why is the difference in power consumption so small?
Does NVIDIA have some test data about this?
