If the NX could maintain this gap between it and the current next-gen consoles, I'd be relatively ok with that. This is that Unreal Engine 4 demo on PS4 Vs. Tegra X1:

Yes the Tegra X1 version here clearly is lacking some of the effects and details of the PS4 version, but it is essentially the same scene. Keep in mind too the X1 footage is recorded off screen by a cell phone camera, so its kind of an unfair comparison towards the X1, but you get the idea.
And y'know, doubling the memory bandwidth, improving the CPU, and the moderate spec bump X1 gets from going to X2 could close this gap a bit further too.
But this is assuming Nintendo pushes the Tegra tech to its maximum, which is yet to be determined as well.
