I imagen the NX will be BOTH a handheld and a home console; they will have certain shared features and compatabilities, maybe even some games. Releasing a new home console next year would mean that PS5 and XB2 would be severaly mpre powerful than Nintendos next effort. And we all saw how bad that went down this gen. 


AMD's 2016 APU's look to perform about as well or better than a PS4 while only consuming 15 watts
.  They could make it so it consumes 5w and works as a handheld while mobile, and then when you plug it into a wall all of your games go from 30 FPS to 60 FPS and at 1080p instead of 720p or something.  That would be sweet...

Do you have a source for that claim I've bolded?

It doesn't seem very likely, given that AMD are apparently moving down to 16nm in 2016. At 20nm Nvidia claims their Tegra X1 can produce 400GFlops of compute performance at 10 watts, even though 16nm is about 25% more efficient than the 20nm process Nvidia uses for their SOC and current parts, it's not going to allow for a drop that steep.

Tegra X1 scaled up to 5X could produce around the same performance as PS4's SOC at 50watts, Nvidia tends to be more efficient in their architecture than AMD, so comparing as like for like as possible maybe AMD can get their Zen APUs down to about 40 watts and that's assuming they have a really good efficient chip design for their next gen SOCs.

A 15 Watt SOC, with the same performance as PS4 is a few years away after 2016.


AMD has a lot more experience in true integrated graphics than Nvidia.  Look up the leaked benchmarks from the upcoming Carrizo APU.  It's true that it likely will be weaker than the PS4 and maybe even the X1, but it would still be close enough to run modern games.


That's really not the point, the point is what's possible at the latest fab scales, you made a claim that AMD's next APUs for 2016 could perform as well or better than PS4's SOC and run on 15 watts. NVidia's designs of GPU tend to be more efficient than AMD's.

A 15 watt APU isn't going to beat PS4's SOC or even come close to matching it for performance.

 

Carizzo is a 28nm APU, with 512 Stream Processors or 8 Compute units, 2-4 Excavator CPU cores the desktop varient uses about 35 watts, which means efficiencies have been made, but they're not sufficient to put a 16nm SOC, with PS4 level specs, at that level of power consumption. A SOC, with 8 excavator CPU cores and 16CUs would run at around 1.7TFlops for 70 watts, PS4 is close to 2TFlops (taking it's CPU and GPU performance into consideration), so it's within spitting distance.

The 35 watt chip is less than half of the performance of PS4's SOC, CPU wise it may be better, but the graphics side is substantially weaker. Powerful enough to run modern games at HD resolutions at 30FPS, with low graphical settings, but those games wouldn't look great, I doubt Nintendo could be shooting for that low a level of performance, not in 2016/2017, not even if they launched this year.

Considering that Excavator is an evolution of current AMD architecture and they've managed to get some pretty decent efficiency improvements with slight tweaks to their current designs, on the same manufacturing process, a full, brand new process and brand new architecture design could yield bigger gains than I thought previously, but still not 15 watts for a SOC with PS4 levels of performance at 16nm. Maybe around 35 watts for PS4 levels of performance.
