Even ignoring the bandwidth limitations the PS3's GPU is not as powerful as the Xbox 360's GPU.
What a strange comment, maybe they count the internal bandwidht of the Xenos daughter chip which is misleading as for example the Cell's internal bandwidth is even greater and shouldn't really be included.
The RSX has two dedicated buses, one dedicated bus to its main memory at 22.3 GB/s and 20 GB/s Cell=>RSX and 15 GB/s RSX to Cell, the Cell is powerful for tasks such as deferred rendering (Killzone 2) giving the results to the GPU or access the XDR RAM connected to the Cell (which shouldn't be needed but is possible).
The Xenos on the other hand has to share 22.4 GB/s for its main RAM with the Xenon CPU.
