We all now that Nintendo will use an ATI AMD graphics chip with WiiU, but apparently both Microsoft and Sony will also go red with their next consoles.

Going with AMD makes sense for both Nintendo and Microsoft as they are using their chips with their current gen consoles and this guarantees that almost every game launched for Wii or Xbox360 will work with their next consoles. And you can ask Microsoft how troublesome can be going from one camp to the other, not every game launched on the original xbox(Nvidia) works in the xbox360(AMD).

The shocking news if true is Sony. We haven't heard of any troubles between Sony and Nvidia that may have caused this change and (again, if true), they won't be able to have fully backwards compatibility. Again. So, why would Sony do that?

Anyway, if true that means 2 things:

1-AMD would have scored a major win over Nvidia. Being the provider for the 3 console manufacturers guarantees them a lot of sales and revenue that their rival couldn't threat. It could also lead to an advantage with the coding of PC games, that may end runing better on AMD GPUs.

2-Having the same(or very similar) GPU architecture on all the consoles would simplify the work that has to be done when porting a game from one console to another, meaning that multiplatform games would be faster, easier and cheaper to make.

well considering how dev friendly psv is...I wouldn't be shocked if this is the path they take

sounds resonable

AMD chips use less power for better results so that makes sense. If you're going to have a 200 watt power supply, and a decent GPU along with other good components, AMD is the way to go.

Yes, but at the end of the day going with either AMD or Nvidia won't make development more difficult, so why go that route with all the troubles it can bring?

Very true, but if (a big IF) they announce the PS4 next year and launches it at the end of 2012 or 2013, they could use the 28nm fab. process so the heat and consumption wouldn't be of much concern.

well the only problem would be BC right? but again I won't give these rumors much weight. Remember all those Tegra rumors around PSP2?

Yes, rumors also said back then that Tegra would be used in 3DS.

And as one the sources say (Hardoc) Sony decided to go Nvidia just 1 year before the launch of PS3, so with them anything is possible.

That'd be so.damn.awesome.

I got a 4650 HD for my old Pentium 4 rig and a 6670 HD as a birthday present for a good friend of mine (quite an upgrade from a 8400gs ;) ). Said Pentium 4 can run SC2 @ Ultra and 1080p!

Needless to say, I love currrent AMD GPU's. GO FOR IT!

For Nintendo it (probably) doesn't matter which architecture they choose because backwards compatibility can (probably) be handled through software emulation of the Wii/Gamecube. For Sony/Microsoft it shouldn't be an issue because they probably restrict access to the GPU through an API (DirectX or OpenGL) which acts as a hardware abstraction layer; similar to how they operate on a PC.
