Halo 3 is a 5 year old game. Grand turismo 5 has been in production for 10 years. How are they even comparable games? Halo 3 had a specialized lighting engine on top of the game which made each frame to be rendered 2x thus requiring more power. The gpu and CPU inside the xbox 360 is more capable than the ones inside the ps3. Not only that but the memory architecture inside the xbox is far superior than the ps3. The EDRAM inside the 360 gpu allows the 360 to actually have AA. Look at how grand theft auto 4 on 360 and ps3. PS3 ran at 640p with no AA and lowered textures while the 360 ran at 720p with higher textures and 2x AA.
Almost every multiplatform game looks worse on the ps3. The ps3 exclusives also look worse than the 360 exclusives. There is really nothing to it. PS3's hardware is weaker on paper. The CPU can't effectively be coded for and the gpu is weaker than the 360's. It has no on die ram so there is never anti aliasing. It can't use as high quality textures as the 360. Overall it is the hardware inferior console.
Oh, your god, that was horribly wrong.
Link to this "lighting engine" ?
"Not only that but the memory architecture inside the xbox is far superior than the ps3" - lulwat? You do know the PS3 uses 256MB of GDDR3 and 256MB of Rambu XDR2 DRAM, right? - Monumentally faster!
"PS3 ran at 640p with no AA and lowered textures while the 360 ran at 720p with higher textures and 2x AA" - No, the Xbox does not have any form of modern AA; you just pulled this out your ass.
"The ps3 exclusives also look worse than the 360 exclusives" - Being that the only new (decent) exclusive is Halo, I'd like to see some proof.
"PS3's hardware is weaker on paper" - At what? Floating point arrhythmic, anisotropic filtering etc?
"The CPU can't effectively be coded for and the gpu is weaker than the 360's" - You probably meant to say something along the lines of "it's harder to develop on".
"It has no on die ram so there is never anti aliasing" - What your saying is completely insane. The Xbox does not have on "die" RAM, nor does that play any role what so ever with AA
All in all, looks like you pulled 95% of that from thin air.
