Google Pixel C might be a good comparable. It has a Tegra X1 processor at 80% of full clock, at dimensions of
9.53 in x 7.05 in x 0.28 inch deep. It also has a monster 9243 MaH battery (32 watt hours).
But lets assume NX has similar width, bring it down to about 9.5 wide, but it's not as tall since it doesn't need to have a 10 inch display ... so lets say 4.8 inches tall, but similar thickness to a PSVta, which is 0.7 inches ... the added depth would make a huge difference it effectively more than doubles the internal volume.
If the Google Pixel C was 2.65x as thick even if you reduced its height, likely the Tegra could full clock.
