[QUOTE="Rashpal"][QUOTE="aarons914"][QUOTE="TriangleHard"]Ok first
John Carmack > IGN.com, I'll trust John Carmack over IGN.com and John Carmack said PS3 is more powerful system but only by a small margin.
second, RSX is actually more powerful GPU than Xbox 360. The difference comes from VRAM.
PS3 has 24 pipeline while Xbox 360 has 48 pipeline, which is due to Xbox 360s unique structure of sharing 1 512 MB RAM with CPU and GPU, while PS3 uses 1 256 MB RAM strictly on GPU and 1 256 MB RAM on CPU.
Does that mean Xbox 360 is more powerful? The answer is no because of power of RSX, PS3 pipeline can do almost 3 times amount of task Xbox 360 can.
so think of it as that Xbox 360 GPU can do 48 tasks at once on 1/3 of speed of PS3 and PS3 GPU can do 24 tasks at once but 3 times the speed of XBox 360.
As for the question why PS 3 looks not as good as Xbox 360, the answer is simple.
First PS3 has complicated hardware architechture especially when it comes to Cell processor, making it difficult for game developers to take good advantage of the system
but Xbox 360 has very developer friendly hardware architechture starting with their Xenon, making it easier for game developers to take good advantage of the system. Also it's been out for longer so developers are more used to the system.
Well that's how I understood it after a little bit of research.
So what does this mean?
Anything PS3 can do Xbox 360 can do, and anything Xbox 360 can do PS3 can do, just in different ways.

Actually ps3 and xbox's gpu operates at 500mhz, ps3 has 32 total pipelines and xbox has 48 unified pipes, ignoring the fact that the 360 is much more efficient that is 1.5 times more graphic power right there and yes the ps3 has 256 VRAM, the xbox can use much more than 256 for video memory if it needs it. Do more research and actually comprehend it this time.
The fundamental flaw of course in this logic is that if it did use more ram on graphics it would take away ram for CPU intensive tasks...So you're saying the 360 devs can CHOOSE what they use the RAM for instead of capped at 256 for system or video? Yeah Id say that was pretty smart of MS too.
That's exactly what the single RAM was designed for. gnutux
