Pascal and Pascal Tegra (P1) are different things, it can still use the minor changes that Pascal saw over Maxwell in the GPU without actually ever becoming Pascal on 16nm as a P1 Tegra designation.
In fact, the lack of P1 in the Shield and the, at one point, expectation of Pascal P1 in the Switch or "Nintendo was looking into Pascal" from Nate, could well explain the fall-through we had a month ago now. Its looking like Tegra P1 just never manifested outside of the PX2 (Denver cores, and a rather large chip too boot) drive for the cars and could/would not be made into a smaller form-factor. Its become very clear that Pascal was nothing but a stop-gap to Volta's delays. There may well not even be a reason for either nVidia or Nintendo to have pursued making an official P1. And the V1 will be the next actual Tegra branch.
If the N1 (Nintendo Tegra) is "Maxwell Gen 3" as a derivative/amalgamation of Maxwell Gen 2 + Pascal features but with or without a 16nm die-shrink, we may well have wrapped up most if not all of the mysteries around this device's rather weird history of architecture talk barring the fans.
Of course, we also have no idea what dev kit clocks Eurogamer reported, and there's the "mysterious stronger dev" kits in October.... and we haven't a word on changes for the November dev kits that were reported near end of the year last year. So there's still a lot of details floating in the air with no real information on them, or at least a lack of clarity of where the information we have has come from as there's been no ascribed time table to Eurogamers information relative to the information we have on at least two different dev kit "powers" and three different dev kit release windows of July, October (boost in performance), and November (no information).
