I wish people would discuss this issue with a bit more fairness. Despite there being getting on 7 years between th launch of the psp and 3DS there does seem to be a few issues with the 3DS technically and its fair to say we should compare the 3DS to the PSP rather than 3DS vs NGP because Nintendo have not pushed the envelope at all in the technology it has apart from the 3D function.
On this very thread someone has linked to 3DS graphics from a development machine not a actual 3DS at all and compared it to PSP. That hardly seems fair. Also a ton of 3DS games are full of short clips of fmv which is pre-rendered on more advanced hardware with the actual gameplay jumping down in visual quality. Despite characters in the foreground being highly detailed I've found objects in the background on many games look low res with poor textures.
Games like Dead or Alive only work at 30fps in 3D mode with frame rate issues but a full 60fps in 2D mode but remember the 3DS only has a 400x240 resolution screen in 2D mode less than the psp's 480x272.
Many PSP videos are taken directly from the PSP's tv output where as tv output from the 3DS is from development systems due to lack of output on the 3DS itself.
Both PSP and 3DS are capable of showing detailed fmv footage at their respective resolutions. So its important to concentrate on gameplay footage for comparison.
The 3DS has a 133mhz gpu which is clearly more upto date and advanced that the psp's gpu although the psp has a speed advantage that its can run upto 166mhz.
The dual core arrangement in the 3DS is 2xarm at 266mhz where as the psp has a core mips processor at upto 333mhz and a secondarly core at upto 333mhz too but it doesn't directly have access to the gpu. It's mostly used for decompressing mpeg4 etc but is also a fully usable processor.
Graphically the psp can't quite do all the tricks of the 3DS but in cpu terms its as powerful or more powerful!
They both share 4meg video and 64meg main memory but the early psp1000 only has 32meg main memory and games have to provide compatibility with both the slim/go models and the early model.Often this means additional loading or graphical tweaks to have dual compatibility. Less ambitious games don't need to change anything.
You can not just overlook the fact the PSP has a higher resolution this clearly means in one way its graphics are superior to 3DS no question.
There are many wii, psp and ps2 games that were jointly developed due to similar resources.
Also cartridge sizes for the 3DS, for a long time Nintendo always used megabits instead of megabytes to describe its cartridges there has been no announcement that they have stopped doing this so the carts are more than likely 2gigabits rather than 2 gigabytes. Clearly games like streetfighter 3D which had an issue that it can only fit one speech set on the cartridge is struggling for space which means these are probaly small cartridges. The jap version only has japanese speech and the european/usa version only has english. Its pretty obvious these are 2gigabits, i.e. 256 megabyte cartridges which means they are only tiny capacity cartridges. Ridge Racer was 32meg on the DS and I'm sure the latest 3D version can easily fit into 256megabytes, 8x that size. It would be ridiculous to think that Ridge Racer needed 2 gigabytes looking at it especially when the DS version was 32meg. It only seems to have a 16bit palette for a start and doesn't look 24bit.
PSP games can hold upto 1.8 gigabytes which is much more generous and also even the NGP which is much more powerful than either psp or 3DS only has 2 or 4 gigabyte cartridges. However Sony are honest with their cartridge capacities. Nintendo are claiming carts upto 8gig in future but this is clearly really 1gigabyte as there is no way the 3DS could use 8gigabytes realistically.
I would put both psp and 3ds in the same camp because they both provide games of a similar ambition which is equivilant of dreamcast/ps2 level. Even though the 3DS may be capable of greater graphically detail I think the slower arm processors and the fact the 3DS has many more background tasks to do means its not capable of such ambitious games as psp.
So far 3DS games are N64/DS conversions with updated graphics or PS2/DC level with some compromises. We are not seeing game worlds as ambitious as wii or original xbox. The psp can do full versions of xbox/ps2 games like Grand theft auto and Monster Hunter Portable to a similar level to wii. What we are seeing is games like Ocarina of time (a 32meg n64 game).
So yes the 3DS may be capable of slightly better graphical level albeit with less resolution but its game worlds are looking pretty limited so far and its not showing the ambition of some psp games. Where are the conversions of windwaker or other classic gamecube and wii games?
So if you make the comparison that the psp offers higher resolution and more diverse graphics due to greater storage I think the psp competes quite well.

I used the above trailer as its gameplay or game engine footage rather than the other trailer which uses pre-rendered footage from a more advanced system.
Mind you saying all that I still use my DS more than my psp as for portable gaming and I don't find graphics the number one importance in a portable system but there is some annoying hype about the 3DS which is getting a bit ridiculous.
I'm sure people will realise that when they get one, nice 3D effect but not that powerful a console.
Can we just have some realism about the 3DS. The tone of this thread is like the 3DS is many times better than psp but where are you getting this information?
The specification was leaked sometime ago and it was all over the internet 133mhz gpu, 266mhz dual core arm processor. I think Nintendo were forced to aim low on performance because the 3D screen draws a huge amount of current for its size due to it having to be extra bright for the 3D effect.
Just to conclude the 3DS does have better gpu technology than psp but that is clearly not the whole picture.
