I guess I can try to post something useful.
Some of the initial questions -if real- only relate what we should already know.
The X1000 series and the Xenos chips designs come from about the same period of time and there raw power is fairly similar.
The “Edge†that the Xenos design has predominantly comes from the fact that it is a closed platform design and therefore has the luxury of using chip real-estate to target key development hurdles.
The value of these specific enhancements isn’t likely to make itself apparent in the early generation of games. But like all console designs before it, it will mature significantly more than a comparable PC part would ever hope to. This is mainly Due to the focused development that it will enjoy for the next 4 to five years.
The question comparing the brought the RSX into this likewise is lacking in long-term value as the final implementation benefits, won’t be seen until late in the PS3 life cycle. This makes the comparison moot, if not outright erroneous due to the lack of concrete evidence as to the final PS3 Design.
As to the later questions they provide interesting insights into Xenos, are they accurate?
Any developers want to PM me I will gladly keep your NDA secrets safe.
I hate it when you have to edit your post, because you changed your mind on which smilie fits best.
