The 360 has its frame buffer set aside from the 512MB of RAM. The PS3 has to share its frame buffer within the 512MB of RAM.

Go ahead and think that won't affect performance in identical situations. It won't actually make that effect go away.

Yeah ,and the 360 shares its only data bus for the GPU and the CPU while the PS3 has 4 data bus connecting each Ram unit (256Mb each ) to both the GPU and the CPU .

 That doesn't give the PS3 greater performance. It's not the number of buses, but the bandwidth and clock speed, which is nearly the same on both (mostly; the PS3's system RAM has a greater clock speed, but that's nullified by the slower latency*).

 

 *That was deliberate. That kind of RAM is great for FMVs (DVD and blu-ray playback), but not so great for graphics.
