That is not true at all, Not all Chipsets have the same exact power draw. Some require more power  consumption There is Energy-Efficient CPU's and Some are not as Efficient. its not just about better semiconductor processor dies also,  but also the Vcore of the processor itself, does the Mem Controller is that single or dual channel what scale is it what's its  Process Geometry @? many thing's go into the power consumption clock Freq. its not based on what Hz/ it seems you have a perception what you think it is not what it really is.

The fact that Arm does not design a ARM 11 past 1 GHz excet maybe in single core only @ 65G , and that Some one already showed you anyway:

look at this chart. and look on the left and than look at the right side!

                                                   Speed optimized ARM11MP single core   /   Area optimized ARM11MP dual core

http://www.arm.com/products/processors/classic/arm11/arm11-mpcore.php

865 MHz = Speed optimized ARM11MP single core

427 MHz = Area optimized ARM11MP dual core

yes you can indeed over clock or under clock a CPU within limit's

So How Many ARM 11 Core's are in the Nintendo 3DS? That Is RIGHT the 3DS has TWO which make's it that Each core will be

427 MHz = Area optimized ARM11MP dual core

or Less, can it go higher for each core, yes and over clocking any CPU can kill it and make it unstable, Like i stated you can over clock any CPU a certain extent.

Like for instance to get near the clock Frenq. you were talking about you would need the Quad core ver. of the ARM 11

732 MHz = ARM11MP 4 core

that is still 732 MHz and remember that is still not taking into account no vector floating point (VFP) 

you can use QNX, but its not as Efficient due also  Process Geometry for fab.of your chip also plays a big part of power consumption of your chip ,than you have leakage that can use even more power even in sleep states.

to even reach that 1.8 GHz mark you stated.single core most likely would be the only way if @ all

3DS - PICA2000:

• 400 MPixels/s @100 MHz
• 1600 MPixels/s @400 MHz
• 40 MTriangles/s @100 MHz
• 160 MTriangles/s @400 MHz

VITA - SGX543MP4+ (4 cores):

• 1000 MPixels/s @200 MHz per core
• 35 MTriangles/s @200 MHz per core

If you are talking abou the new title, well I have heard other people who say they own the Vita say that it doesn't do it.

But if it already does it then; my bad.

Thanks, that would go well with info I got from a user name Drago on yahoo answers:

ok i am really tired of this crap how foolish the people are they even dont know about nintendo 3ds cpu and its hidden capacities i open 3ds myself and i found out about

I think he got confuse from the RAM efficiency or something. But you get the point.

Anyways these are the facts of the custom made chip in the 3DS.

I think you need better sources lol. The only feature the 3DS has that Vita doesn't yet is Folders.
