Speculation time:
The recent FCC filing indicates the Switch has a 39W AC adaptor. I have a few questions about this info. First off, does this mean that 39W will be supplied to it when connected to power (in or out of the dock)? Or does this mean that up to 39W will be supplied?
Second, to compare, the Shield TV had a peak power draw of ~20W. This includes the HDD, which I think is somewhere around 6W if I'm not mistaken. The Switch will have a battery that needs charging, but otherwise the clock rates we've been given say it should draw around 4-5W in portable mode and probably close to 10-12W in docked mode, if we're going with the assumption that it's a straight TX1. How much power is generally needed to charge a battery? Would that account for the remaining 27-29W? That seems far too high to me.
There could be some power reserved for powering peripherals, like the Gamecube adaptor or (if LKD is incorrect) an external HDD. How much power are we generally talking about there? No more than 6-7W, right?
So basically, I think we should be able to get a very rough estimate of how much power the Switch will consume in docked mode at the very least. And it seems to be higher than what we'd expect with a TX1 at the given specs. Which, firstly tells us that it's likely not 16nm- as that would require less power- and secondly tells us that there's likely more on that SoC than what we see on a standard TX1, especially a Jetson TX1. So this would likely suggest either more SMs, more CPU cores, more RAM modules... or some combination. Anyone have any estimates here?
