really, where have you been this entire genreation???
there's been like TONS of hardware comparisons and they have all came to the same conslusion that the ps3 is in FACT more powerful than the 360, not to the extent some ps3 fans would like to believe, but it's still a fact. I'm not making this up......
Comparison of GPU specs
Clockspeed in MegaHertz: 550 (PS3), 500 (360)
GigaFlops (Billions of Floating Point Operations Per Second): 1,800 (PS3), 240 (360)
Billions of Dot Products per Second: 1,800 (PS3), 240 (360)
Millions of Polygons per Second: 900, 1,800 with CPU handling culling (PS3), 500 (360)
Shader operations per clock cycle: 136 (PS3), 96 (360)
Billions of Shader operations per second: 74.8, 100 with CPU (PS3), 48 (360)
Texture lookups per clock cycle: 24 (PS3), 16 (360)
Texture lookups per second: 13,200 (PS3), 8,000 (360)
Vertex/Pixel Shader pathways: 24 pixel, 8 vertex (PS3), 48 shared (360)
Shader ops per pathway: 5.7 (PS3), 2 (360)
Video RAM
Amount in Megabytes: 256 Dedicated, 256 Shared (PS3), 10 Dedicated, 512 Shared (360)
Clockspeed in MegaHertz: 700 Dedicated, 3,200 Shared (PS3) Unknown Dedicated, 3,200 Shared (360)
"The PS3 has the upper hand in all areas. Theoretically, the GPU is about 2-3x faster on the PS3. Although the 360's unified 48 pipe architecture is very efficient, it only performs 2 operations per pipeline. The PS3 has dedicated 24pixel and 8 vertex, but they are both capable of 5.7 operations per pipeline."
CPU:
Cell Processor
- One general purpose PPE core that is used for the OS and the game application.
- 512 MB total memory on 2 buses which can be accesed directly only by the PPE core. 256 MB of processor main memory and 256 MB of memory used by GPU.
- 512 KB L2 cache for the PPE.
- 32 KB L1 instruction cache and 32 KB L1 data cache for the PPE.
- 7 specialized SPE cores. One is used for the OS leaving 6 for the game application.
- 256KB SRAM per SPE. No common memory between SPEs and SPE cannot access the PPEs main memory directly but the PPE can access the SPEs memory directly.
- Communications between SPE memory or to the PPE memory is performed via the Element Interconnect Bus (EIB) by either accessing ports or via DMA.
- SPEs do not have branch prediction capability.
Xenos Processor
- 3 General purpose PPE cores that are used for the OS and game application.
- 512 MB main memory that is shared by all three cores and GPU.
- 1 MB of L2 cache that is shared by the 3 cores (333 KB per core average).
- 32 KB L1 instruction cache and 32 KB data cache for each core.
Programming the 360 is fairly easy and straight forward since a large amount of shared main memory is available, a relatively large amount of shared L2 cache is available, and information can be quickly and easily passed between different threads (cores) of the application by just passing pointers.
The PS3 is so much more difficult to program than the 360. In a sense it is designed similar to multiprocessor systems used by specialized customers such NASA Ames Research Center. The concept is based on the principle that there is a very large amount of repetitive mathematical data that can be performed in a parallel or a segmented sequential fashion (ex. one core multiples two arrays of 10000 numbers and then passes the output array to another core which performs divides on individual elements in the array which will pass the array to another core which performs some other operation on the data, etc. After the first core finishes its operation, it will acquire more data and perform the same operation).

see i told you.
360 is in FACT more EFFICIENT, due to it's straight forward approach and unified architecture
but overall the ps3 is more powerful
sorry to burst your bubble dude.
