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

So we're looking at 15.3M polygons/sec for the PICA 200 GPU (@200MHz) in the 3DS vs 133M polygons/sec of the SGX543MP4+ (@200MHz) in the Vita.

For the CPU side.. we're also looking at dual core ARM11 CPU (@266MHz) vs quad core Cortex A9 CPU (@800-1000Mhz). The Cortex A9 architecture is leaps and bounds ahead of the the ARM11 ones and theres 4 of them!

There's no discussion about power between those 2 handhelds. Its more powerful than PSP, sure.. but nowhere NEAR the PS Vita.

Did a little more research and I don't think the 3DS's GPU runs at 400Mhz, so yes, 15.3M polygons/sec seems right. I also thought the 3DS's CPU ran at 1Ghz, so many bullshit stats being thrown around.

We should make a table to put all this in.

15.3M polygons/sec is for the 2006 version at 200MHz. Here are the specs for the 2008 ver.(65nm), which clocks in about 40M Tri/sec at 400MHz: http://people.csail.mit.edu/kapu/EG_08/Mobile3D_EG08.pdf

Also, no doubt it's running lower than 400MHz. The maximum allowed core frequency is almost never used in portable devices because of heat and battery issues. About the CPU, nobody knows. I find it quite hard to be two ARM11's at 266(and with one being used to wireless functions, so pretty much only 1 core for graphics), since the graphics shown on the 3DS absolutely wouldn't be possible with such an old chip clocked that low. ARM11's can go up to 1GHz, I don't even believe it's possible to underclock one as low as 266MHz.

The ARM11 CPU was used in the E3 2010 prototype with NIVIDIA 200 MHz GPU and NO Motion Sensors.

The finish 3DS uses a Nintendo Unknown CPU (seems to be 800 MHz a core on firmware 1.0.0-0 as an underclock, which would explain short battery life, I suppose) with PICA200 GPU (2008 or possibly a 2010 Model) and HAS Motion Sensors.

3Dbrew, is like going to beyond3D for Wii U specs.

Plus the 3DS has at least 9 MB VRAM and the external storage is Toshiba 2 GB with internal memory of 1.5 GB.

Any proof for the 9 MB VRAM? Perhaps another yahoo-source?
