Turns out I forgot that little detail -- which would have happened no matter how much of an expert I was or wasn't. Oh well. But still, there has to be some advantage "1 core and 7 SPEs [edit: AND a GPU]" has over "3 cores and 1 GPU". It just can't be a one way street.

[edit2: And it may not be intentional, but you now seem to be saying that the PPE has to do AI and physics, instead of being able to move physics work to the SPEs.

[Also, one of the SPEs helps to run the OS as well as "security", so that does in fact take load off of the PPE that remains on the Xenon in the 360. (http://en.wikipedia.org/wiki/PlayStation_3_Hardware )]

Of course there are advantages of 1 core, 7 SPE, I GPU over 3 core, 1 GPU. That advantage is not AI, due to the design of the SPEs and the nature of AI. However, many other things will of course have benifits on the Cell architecture. You're exactly right, it can't be a one way street ;)

as for your edit2, no it's not intentional, Physics will be on the SPE's. However, you have to remember that there are many other things other than Physics and AI that will have to be run on the PPE.

 

I would never have guessed that considering I just mentioned that the OS runs (partially) on the PPE. (/sarcasm)  But as you can see, many of those things are also able to be done by the SPEs.  Yes, there are some things that the PPE simply must do, such as coordinating the SPEs, but I doubt that that will cripple the Cell's performance.  

It seems (here I also look at your dialog with MikeB) that you are now shifting (or perhaps clarifying) your argument from "the 360 architecture can do BETTER AI" to "the 360 architecture can do AI more EFFICIENTLY", which is a completely different argument, and one I am much less inclined to take issue with.
