I'll paste my Engadget comment here:
The nVidia shield released when the iPhone 6 was the current model. Now the iPhone 11 is the current model: with it, the Manhattan benchmark has gone from 20 to 110 fps, so a 450 percent improvement over the same time period. If Apple can do it, I'm pretty sure nVidia could do the same. The new nVidia shield should be 450 percent faster for the same price, not 25 percent faster. Even the Raspberry Pi has seen much more improvement than the Shield in terms of speed. If Apple updates the Apple TV again to the A12X processor, I'm dumping my nVidia shield, I'm tired of their neglect of the platform (which considering how much Apple has neglected their potential, that's saying something). Roku and Apple TV for me. Even the $35 Raspberry Pi 4 has a faster CPU than the nVidia shield now.
