How does the 3DS compare to the PSP, power wise?

Tadaa. Surprised I didn't think of that before, checking DMP's website. If 3DSbrew is right about the 3DS's GPU clock core, then it will be achieving around 20M polygons/sec, about the same as the Gamecube I believe.

Still not sure about the CPU. Early reports before the 3DS was released said it was either two ARM11's or a dual core ARM11 at 266Mhz, I've seen other "sources" that say it's higher than that though.

Check a few pages back. I pointed it out, yet everyone continues to ignore it and choose to beleive their in own "sources". I beleive its 2 ARM11 CPU's and not dual-core (sorry I didn't bother correcting myself before).

About the CPU - www.arm.com/products/processors/classic/arm11/index.php?tab=Specifications

ARM11 Processor Family

"The ARM11™ processor family provides the engine that powers many smartphones in production today and is also widely used in consumer, home, and embedded applications. It delivers extreme low power and a range of performance from 350 MHz in small area designs up to 1 GHz in speed-optimized designs in 45 and 65 nm. ARM11 processor software is compatible with all previous generations of ARM processors, and introduces 32-bit SIMD for media processing, physically tagged caches to improve OS context switch performance, TrustZone for hardware-enforced security, and tightly coupled memories for real-time applications."

Considering that the 3DS has two of these in its low profile design, they would have to clock it in the lower regions for the device to have an acceptable battery life. The 3DS has a 1300mAh battery so it would not be farfetched for the CPU clock frequency to be set to 266MHz. The PSP CPU in comparison runs at 222MHz ~ default and can be set to 333MHz (this can be set lower, mind)

Here's a battery life comparision -

Platform	Battery capacity	Claimed battery life	Charge time
Nintendo 3DS	1300 mAh	3DS games: 3-5 hours. DS games: 5-8 hours	3.5 hours
Nintendo DSi XL	1050 mAh	4-5 hours (highest), 9-11 hours (medium), 13-17 hours (lowest)	2-3 hours
Nintendo DSi	840 mAh	3-4 hours (highest), 6-9 hours (medium), 9-14 hours (lowest)	2-3 hours
Nintendo DS Lite	1000 mAh	5-8 hours (high brightness), 15-19 hours (low brightness)	3 hours
Nintendo DS Fat	850 mAh	10 hours	4 hours
Game Boy Advance SP	700 mAh	7-10 hours (high brightness)	3 hours
PSP Go	930 mAh	3-6 hours	2-3 hours
PSP 3000	1200 mAh	4-6 hours	3 hours
iPhone 4	1420 mAh	10 hours video time. Less for Infinity Blade.	2-3 hours
