[QUOTE="ps3rulezzggdff"][QUOTE="Redfingers"][QUOTE="ps3rulezzggdff"][QUOTE="Redfingers"]Split memory has been a staple of PC gaming since the dawn of time. The dark days when it was using shared memory were sad indeed, seeing as shared video memory is slower than dedicated memory. That's right. That means that the Playstation 3's video memory is faster than the shared memory in the Xbox 360.
Additionally, so is it's main memory, since it's XDR. It has higher bandwidth and presumably much lower latency, meaning faster.

you have no clue what you are talking about.
ps3 XDR ram has 25.6 gigabytes of bandwidth
ps3 gddr3 has 20.8 gb bandwidth
xbox360 has gddr3 with 22.4 gb bandwidth and 10 mb edram with 256 gb bandwidth.
share memory has never been done on pc, only graphics cards and pc main memory is too slow to use used as graphics memory.
Actually, I do have a clue.

"Main RAM -- 25.6GB/s VRAM -- 22.4GB/s"
As far as I know everything you wrote is essentially misinformation. The VRAM means GDDR3 by the way.
Who'd have thought. GDDR3 clocked at 700 MHz both in the 360 and the PS3 happens to have the same memory bandwidth. Shocker!
actually RSX gddr3 was downclocked to 650 mhz so the bandwidth is 20.8 at 700 mhz it's 22.4 gb but got lowered in clock.
also, xbox360 10 mb edram has 256 gb bandwidth so owns XDR+gddr3
Link me.
lol, the the framebuffer is probley the biggest bandwidth hog and it basically eats all xdr+gddr3 bandwidth.
while xbox360 while it's only 10 mb ram it has freaking amazing 256 gb bandwidth, so basically 22.4 left just for other crap.
