the 360 have 512Mb ram while the Ps3 have 256Mb & we all know that Xenos Gpu better than Rsx also from what i heard before the Cell is not proved for games. |
this is from 1UP its about the GPU
summary:
The Xenox, built ground up by ATI, is capable of using today's graphic's engines to make some amazing looking screens with 10 mb of memory dedicated to 4x Anit-Aliasing (smoothing of jagged lines) at no cost to graphics horsepower. 332 Million transistors and 48 pipelines allow for lots of texturing, able to be flexible enough to do geometries (not currently the case) or pixels (much more used currently, especially by the Unreal engine, which is licensed for use the the vast majority of game developers) as needed. The GPU is linked very closely to the CPU, and is able to shift 512 mb of RAM towards either as needed.
The RSX is based on the G70 and is a card that was implimented late in the game when the cell could not handle graphics processing as was assumed it could (whether due to programming difficulty or simply too much drain on resources). The differences as noted above amount to a lessened memory bandwidth versus the 7800GTX PC cards. This will cause more reliance on the Cells Memory controller and memory banks (which causes a major problem in high detail at 1080p, which is why you are seeing the majority of PS3 games running 720 best frame rates ( True ).
300.4 million transistors and 36 piplines, 24 and 12 dedicated, versus 332 million (that is with the skimping due to unified pipelines, normally 48 pipelines would use a heck of alot more) and 48 pipelines, combined with 512 system memory and 10 mb dedicated 4x AA = roughly 522mb that could be used for graphics (more realistically about 386-412mb for pure graphics due to other needs), versus the 256 mb dedicated in the PS3 just allows for a more powerful GPU on the 360.
