On Jetpack 4.4.1, running the benchmark causes the 2 core power mode to be set, instead of the 6 core one. #24

I did some research. My current best hypothesis is based on an impression that i got from these charts on this page: https://docs.nvidia.com/jetson/l4t/index.html#page/Tegra%20Linux%20Driver%20Package%20Development%20Guide/power_management_jetson_xavier.html#

The max CPU clock speed is 1900Mhz. Based on this it seems that the CPUs can never exceed 1400Mhz in 6 core mode. So I think that maybe the GPU can be fed more efficiently with 2 cores at 1900Mhz than even 6 cores at 1400Mhz. Is this true?
