Doesn't the cell have like 25gb/s of bandwidth from the xdr memory in the ps3?

Yeap... Cell in PS3 have a better bandwidth than the GPU RSX but the Cell do graphics tasks in PS3 at the same time that share RAM with the GPU (the 256MB XDR can be accessed by the RXN using the Cell like a Data Move).

The CPU in PS4 can't do graphcic tasks and it don't need to share RAM with GPU... it is all unifed.
