Absolutely FALSE.
PS3 GPU as you point out, whether going through Cell or not, accessed XDR and GDDR at one.
In fact, this is the ONLY reason Sony even used two pools of RAM in PS3, to get double bandwidth, since 1 is simpler. Use your head!
Sony used two pools of RAM, MS used a single pool+EDRAM, to solve the same bandwidth problem. Had Sony only used one pool of RAM with no EDRAM. PS3 would have had severe bandwidth constraints, because 24 GB/s is not nearly enough to feed RSX.
Choice last gen was this:
Two pool
On pool+EDRAM
The only reason Sony used one pool+no EDRAM this gen (though they considered it, as Cerny said) was because they went to a 256 bit bus. Last gemn 256 bit bus was considered too expensive. They were forced into two 128 bit busses to two pools of RAM, or one 128 bus and EDRAM for 360.

You need to study first... all what I said is true... come back late

Seems like you got owned and dont know how to respond by addressing my points. I understand.
I notice on this board there's a few people who know a little about system design, but nobody knows very much. It's not like B3D or even, horror to admit it, Neogaf (which has a few people with tech knowledge even though the ignorant make the most comments by far)
I'm not an expert, far from it, but I feel like one on this board LOL. I may have the most system design knowledge here.
Not knocking this board, every board has it's character I suppose. Most boards do not have technically informed posters...
