- Erista Switch uses lower speedo (=== lower quality === higher voltage required) SoC from NVIDIA. You will NOT get comparable performance to NVIDIA Shield TV no matter what.
|

- Snapdragon 810 (4 x A57 @ 2.0GHz + 4 x A53) also uses 20nm HPM, see how it plagued Android phones in 2014.

- The board power supply is quite limited, even if you've done cooling mod.

- You could spot battery draining at higher clocks under stress test, even with official 39W PD charger.

- CPU / GPU performance at max clocks will be worse if power supply is not enough.
