Leaks are assumptions. It isn't hard evidence. Wind Waker on the switch was leaked from a 'reliable' source..... What Nintendo will or will not use is speculation. Especially since underclocking is a real possibility like with the current model. |
Sure, if we throw out the assumption that the Switch 2 is using T239, then anything is possible. I was addressing the point that Switch 2 could be T239 AND 8nm.
The post I shared explains why underclocking might not even be an option. There is a point where you can't reduce power consumption anymore by reducing clocks.
Because power consumption is mostly related to voltage, not clock speed, when you reduce clocks but keep the voltage the same, you don't really save much power. A large part of the power consumption called "static power" stays exactly the same, while the other part, "dynamic power", does fall off a bit. What you end up with is much less performance, but only slightly less power consumption. That is, power efficiency gets worse.
So that kink in the efficiency graph, between 420MHz and 522MHz, is the point at which you can't reduce the voltage any more. Any clocks below that point will all operate at the same voltage, and without being able to reduce the voltage, power efficiency gets worse instead of better below that point. The clock speed at that point can be called the "peak efficiency clock", as it offers higher power efficiency than any other clock speed.
