Umm LOL. No it doesnt buddy, Devs were horrified when they first saw the bandwidth speed of PS3 memory.
OK, nice to have this cleared up. You don't understand the figures and no, devs weren't horrified about that inquirer article at all. All Beyond3D guys stated the read speed of the Cell from the RSX's local memory is greatly irrelevant (look up the relevant thread), but the fact that it's there is still useful for some rare testing purposes (on a PC this is not possible at all). The XDR memory is a lot faster for the Cell to work with, for a CPU especially one like the Cell low latencies is very important.
It makes by far more sense for the RSX to use the XDR next to its GDDR3 memory as RSX graphics data is usually much bigger than executeable code and other small pieces of data to be processed, it does not make sense to move such code from XDR to GDDR3 and then read it.
@ thread
That was my last comment on this misconception.
