Edit: essentially, by caching data in edram rather than grabbing it from main memory, Nintendo could be eliminating 50% to 95% of the data transfer across the memory bus making the difference between a $4 memory module and a $400 memory module meaningless.

Dude, the eDram is a FRAME BUFFER, not a cache. The CPU probably doesn't even see it....

And no, when three processors (CPU, GPU and DSP) fight for ram over a single 64bit bus, then there is bus contention issus, all the time

and you have documentation for this I assume?

Yes. Every computer ever built by any engineer. Of course Nintendo SOFTWARE engineers use caching techniques wherever possible in whatever way possible. In case you did not notice, this is a thread about HARDWARE, not software.
