Someone posted this on another website. I'm not super tech savvy, but can someone verify if this could be the case?

I have an alternate theory.
A lot of modern CPUs have power saving features that keep the frequency/multiplier as low as possible to run basic functionalities. For example on Android, the frequency while you are browsing the OS remains very low to save power, and only increases as the system needs it.
I think it is likely the 1.24GHz rumor was always wrong. It was a best guess at best, and a complete oversight of how modern CPUs mitigate their power draw. I think it is much more likely that, instead of an overclock, Nintendo disabled the power saving feature on the Wii U OS to allow the CPU to always run at full speed. This will help with all of the loading issues since the CPU would not have to continously spike and then lower its frequency constantly. I believe this is possible even if there was a slight OC. Anyone who has overclocked a CPU before knows how unstable your OC can get if you do not disable power-saving functions.

What I understand overheat have nothing to do with system limit... it is just about the thermal/colling system... how much the system can dissipate to not reach high temperatures.

The 75W max power draw is about how much Wii U power supply can handle... Wii U can use a 150W pwoer supplu or more without have overheating.

At the same time I can have a system with 10W power supply and have overheating... that was all because the cooling system.

Guys it is already confirmed FAKE lol

So we can't discuss theory of overclocking cause the source is fake?

I seriously doubt anybody is taking this at face value, but nintendo could still do something like this, maybe not as much of a jump.

Ohhhh it is ok to discuss.

I said that more because a lot of comments here seems to really believe that Nintendo can change the clock of CPU from 1.24Ghz to 3.24Ghz... a CPU archtecture that wasn't created to reach these clocks.

As I said in my earlier post. The 1.24 Ghz is a good fit for the PPC 750 architecture. There is no possibility that the Wii U CPU is anywhere near 3GHz. This CPU is not as weak as its clock speed suggests. Take a look at the PS4 CPU .. it is clocked at 1.6 GHz. Because it has a short pipeline it can handle more instructions per cycle.

Just stop comparing CPUs by their clock speed.

Ironically enough, any person who knows how to overclock a CPU would say that person is talking crap. Power saving features don't limit an overclock by any significant amount, only makes a difference when you're already on the edge, and is only relevant on desktop hardware. Biggest red herring I've seen this week, can almost smell it through the screen.

There's so many idiots on the interent, they think that they can just base a whole theory on one little bit of factual information then just fill in the gaps with their pathetic little pea sized brain ideas on the world "just because it fits!"

(not you, person you're saying who said this).

Most of the posts I've seen are just theorycrafting that it would even be possible, not that the rumor is true. And the general consesus is that it is more than likely being overclocked, but not to the specs listed in the source.

Personally I think that Nintendo found a way to engineer real life Pikmin and put 100 in each console (20 of each color of course), but they have to stay buried in the architecture until the leaves turn into flowers (6 months I believe is the incubation period) and now that they are fully bloomed, BAM! 4 Ghz easy!

Have you ever clocked a Pikmin? They are so fast no one has ever seen one.

Quick question for anyone that can answer it..

Has Nintendo ever confirmed the CPU clock speeds for the Wii U?

I can only find links to @marcan42 confirming the clock speeds.

Nope
