Gamespot.com: Microsoft will pair the IBM processor with an advanced 500MHz ATI graphics chip. The ATI chip will have "48-way parallel floating-point dynamically-scheduled shader pipelines." Today's PC desktop video cards max out at 16 pipelines, but the technologies aren't quite the same. The new ATI graphics chip will be based on a new unified shader model that processes vertex and pixels through the same multipurpose pipelines. Current PC video cards have pipelines dedicated to pixel processing or vertex processing. ATI's current top-of-the-line Radeon X850 XT PE graphics chip, for example, has 16-pixel pipelines and 6-vertex pipelines. We don't know how these new hybrid pipelines will perform compared to the older, dedicated pipeline designs, but with 48 of 'em, we're betting that the next-gen ATI chip will live up to expectations.
This advanced technology has allowed Microsoft to substantially raise the bar on visual requirements for Xbox 360 games. Next-generation games must support at least 720p HDTV resolution, 5.1 multichannel sound, and full 16:9 widescreen aspect ratio (no letterboxing). Games must also have at least 2x antialiasing to improve image quality. According to Microsoft's Peter Moore, "Jaggies need to be a thing of the past," and there's no doubt the Xbox 360 hardware will be powerful enough to make them so. The graphics chip will also have 10MB of superfast embedded DRAM, which is just large enough to fit in an HD resolution frame buffer with antialiasing.
The Xbox 360 will have 512MB of system memory, which is shared between the CPU and the GPU. However, the graphics will take up much of the space since the HD video requirements mean developers will have to use larger high-resolution textures to give games extra detail. The extra memory also allows for larger game levels for improved gameplay. Sound will be 5.1 out of the box, but since the all the audio is done in software, the Xbox 360 can easily support additional sound channels if games wanted to move up to 6.1 or 7.1-channel output.

PSI Next: In order to design the most powerful processor possible with current technology, Sony formed a partnership with electronics giant Toshiba and supercomputer expert IBM. Together, the companies have assigned a team 300 engineers and are spending (an estimated) $500 Million to develop a new type of processor which has been nick-named the Cell. The processor is actually a collection of smaller processors. Software packets, called “cells”, are then sent to each of the smaller processors in order to give instructions on what tasks to perform. When implemented optimally, the processor will be able to calculate up to 1 trillion floating point calculations per second, which as you would imagine, is better than any standard computer processor.

The PlayStation 3 is not the only application that will use the Cell, however. Sony and Toshiba plan to make use of the chip in many common electronics, including household appliances. This combined with the possibility of shared computing could result other PlayStation 3’s, or even your toaster providing extra computing power to your PlayStation 3 through a broadband connection. The chip has been designed in such a way to provide opportunities for such innovation.

Time to make some choices here. I'm assuming Playstation 3 will be more powerful than the Xbox 360. However we don't know enough about the Nintendo Revolution to make a conclusion on which console will come out on top. If anyone has seen the alleged Revolution clip, Sony and Microsoft will be in a battle with Nintendo if the clip is indeed real.

Don't forget Nvidia's GPU.
Have to take that into account too.
