Forums - Sony - Sony to use Nvidia Tegra for PSP2; explains delay

Munkeh111 on 14 July 2010

You would assume that it would be custom designed for the PSP 2, so hopefully will overcome many of the problems that other chips have had...

I think an improvement in battery is one big thing for the PSP, its current battery really does suck

I'd rather they went with a VIA chip....VIA is so good at Embedded systems, this I know.



Just waiting for that PS Vita to come out so I can play some full featured games on the go with that beautiful screen and control scheme...

They'd do much better waiting for the ATI APUs imo. Nvidia has always failed to deliver the portable experience vs ATI if you ask me.

I've already said roughly where Tegra's graphics power lies. It will be much more capable than the 3DS if it's based on Tegra, but battery life will be a lot less.


You sure about that? We still don't know what is actually in the 3DS yet we know it's putting out great visuals. If Tegra really is Geforce 6 level then I'd imagine it'd produce graphics close to the 3DS.



The BuShA owns all!

Geforce 6 level is not that impressive so I'd agree.

I think we all know that if Sony chooses to make a PSP2...It will probably have more graphics potential than any other handheld out at the time, including the 3Ds....but how hard it will be to program for, is an entirely different story.

The 3DS looks closer to the Gamecube to me; that's 2001-level tech based on AMD's R100. Tegra is three years newer.

I suppose it depends on process node and power consumption though. Nintendo will choose a less capable chip (for cost reasons) and downclock it (for power reasons) compared to Sony because that's been their design philosophy.

I'd assume that, like DS versus PSP, the 3DS will be $100 cheaper and have double the battery life of the PSP2. And part of that difference will come from the graphics chip.

GameCube could do soft/self shadowing, normal mapping, specular highlights and subsurface scattering?  News to me. ;)

The GPU core in 3DS is based on DMP's PICA chip, which dates back to 2006 as the first iteration btw.  I'm not sure why you're using ATi chips to try and give a timeline versus Tegra?

the poly power won't match, but the effects should be OK(and better than cube or wii since the shader is more updated,) and like you said, battery life is a big factor, 3DS proto type can go 8-10 hours full demo mode during E3 already, that's not something you can answer with a tegra unless you bring out a heavy ass battery.

you forgot fur shading =P but the 3DS can easily outdo cube or wii on effects in the long run.
