It has been 2 years since PS4 and XboxOne released, if Nintendo goes with AMD, I really hope it doesnt pick an APU that much less powerful than the one they other have, which will be really a shame. NX should have at least about same calculation capability if not more than the other two.
But if Nintendo takes the approach to emulate old games by software emulation, I would speculate NX to have maybe a better hardware, which is what I like to see.
