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

The 3DS has a 2-core 2010 CPU, while the Wii has a 1-core 2005 CPU.

Does this help you get some idea of the architecture?

It's hard to find the 3DS GFLOPs. But it definitely has more Shader Cores.

People use to say the 3DS GPU is 200 MHz with 15.3 million polygons, but now everyone says its 400 MHz with 30.6 million polygons.

Cleary we are still learning of the 3DS polygon count & GFLOPs & so fort.

The funny thing is at I have been telling everyone about the 3DS GPU being clocked at 400 MHz since 2011 or 2012, thanks to someone on Yahoo Answers buying an extra one and taking it apart to test the tech.

I can post the Link for you to read his post.

 

EDIT:

Here is the link I found when looking for specs on google. This guy took one apart:

The difference in years between the CPUs is easily countered by the 3DS's constraints in size, power use, and heat.

And no, the year and number of cores doesn't give a good idea of the archiecture, for that we need to know things like cache sizes, pipeline lengths, bandwidth between components, IPC, (Instructions Per Cycle) etc.

Also, the fact that one is a PowerPC and the other an old ARM processor pretty much tells us everything we need to know. Only in the Cortex-A9 series ARM managed to get similar power to a first-gen Intel Atom processor, which, in turn, had comparable performance to a 900MHz Celeron M, which has similar power to the PowerPC processor found on the Wii. ARM11 came way before the release of Cortex-A9 processors, therefore, it's much, much slower than the Hollywood processor inside the Wii, even if it runs at a higher clockspeed. In fact, it's probably even slower than the GameCube processor. ARM only started to significantly improve performance on CPU cores after the release of the Cortex-A8.
