Emily Rogers: NX not gonna use X86 architecture, raw power close to XBO

Should be getting close though. nVidia Tegra 6/Parker looks to be a mobile beast this year and the Tegra X1 is already pretty good.
It's just unfortunate that nVidia is pretty much irrellevant in the mobile space.

Now nVidia went from 192 to 256 Cuda cores when it went from the K1 to X1, 28nm to 20nm.
So it stands to reason a linear increase would mean 320 Cuda cores when it drops down to 16nm.
1GHz * 2 FP 16 * 2 FMA * 320 = 1280 Gflop.

Same amount of ROPS but with quarter of the texture mapping units. Bandwidth though, is another kettle of fish entirely, the Xbox One will beat Tegra for many more years to come due to that fact, Tegra likely has inferior Geometry performance too.

Interested to see what nVidia does in 2017.

Don't get me wrong, I think the NXDS will definitely be able to handle fantastic looking downgraded ports of XBO/PS4-level games by the time it comes out that will look essentially undiscernable from the console versions due to the smaller screen, lower resolution made up for by high pixel density blah blah. But definitely nothing with the power of the XBO in such a small form factor by next year.

Oh I agree.
But not because of the chips themselves though, but because the Memory systems in mobile are poor. (I.E. LPDDR3/LPDDR4 usually single channel.)
Plus the Xbox One released with a 28nm chip that is based on technology that is 4 years old... And it was never fast to begin with.
The advantages of 14 and 16nm compared to 28nm does open up allot of possibilities though.

That said, this is also Nintendo we are talking about, they gave up trying to win the Performance and thus Graphics quality crown generations ago... They likely will not be using the latest and greatest mobile SoC.
