There is no way the chipset is overclocked in any mode. For various reasons:
- first, overclock increase drasticly the heat and power consumption, for marginal gains. The curve of the performances/wattage grow rapidly and then become flat. The "nominal" speed is where the curve begins to become flat. Increasing the speed over that point come as extremely high termal and power costs. As this has to fit in a tablet size, there's no way it will be.
- second, not all chipset can be reliably overclocked. Only higher quality ones do. To make every chip overclock reliably in docked mode would increase significantly the costs since it'd decrease the yelds.
- third, the chipset may come close to heat limitation in a small form factor already before full clock (i think they'll go for a pretty bulky handheld, but 5" is possible too obviously). That said, if the X1 is a devkit, and this is using Pascal, there should be absolutely no problem at hitting X1 performances without heating issues.
My personal assumption is that this is extremely similar to X1 (aka 2 core GPU, 4 core A57/A53/whatever), but with pascal instead of maxwell. Which mean that a 2 core GPU would perform easily above X1 full clock even at much lower wattages and heat targets (
keep in mind the 16nm over the 20nm process make it consume about 60% less W for the same level of perfomances).
I don't see them using 1 core because we'd get a:
- significantly worse GPU compared to devkits even with Pascal
- a different GPU architecture compared to an X1, which mean that translating the code from games in development from a devkit to the new thing wouldn't be AS trivial as it would be if u had identical architecture (Pascal is basically the same as Maxwell but on a smaller node)
I don't see them using 3 cores either because of costs and heat considerations, plus there's no way you could emulate the performances of a Pascal 3 core with a X1, even overclocked.
