XDR memory may have a higher max bandwidth but MUCH higher latency than the GDDR3 used in the 360.
Actually XDR provides well lower latencies, that must have been Sony's reason for going with more expensive main CPU Ram (yes, the GPU can tap it as well increasing graphics bandwidth, but it does not need to within the PS3 design).
