The one that caught a lot of peoples' eyes was the raycasting terrain demo. The whitepaper for it is here: http://www.research.ibm.com/people/a...0-%20final.pdf

Some highlights:

The Input:

The Output:

Performance comparison:

Two impressive things to note are a) the speedup over a G5 (for the PS3's CPU, it'd be 50x vs the 2Ghz G5, and just over 30x vs a G5 linearly scaled to 3.2Ghz), and b) how a 2-chip Cell configuration offers double the performance over a single-chip solution, which bodes well for multi-chip usage.

I haven't read all of them yet, but it seems like interesting stuff

reminds me of:

For example we showed the demo that renders London City, it's not rendered in the GPU but the CELL does lighting and texture processing then outputs it to the frame buffer. Even without GPU, only CELL can create good enough 3D graphics.

it really does seem like CELL can output some great looking stuff, even without RSX .. I can't wait to see what devs. come up with using CELL & RSX at the same time

Didn't understand a word of it but it seems interesting none the less.

The fact is that Both Xbox and PS3's CPU's with not be able to work up to their full potential untill about 2 years. It is also very much harder for game programers to create software that utilizes the cell CPU. It will take them a lot longer on cell then it would on one or 3 of xbox's CPU's to create the exact same thing. You will not see any difference in the current gaming (because it will be similar to Doom 3 and HL2 as far as physics and Graphix) Until after 2-3 years. As you may laready knwo the hardware is moving faster than the software. Both are planning very far ahead into the future as far as gaming goes. But You won't see any majjor difference in performance of gaming software for about 2 years.
