Here's further proof of the 360's superiority to the ps3:
According to IBM’s white pages, the cell processor being used in the ps3 is considerably less powerful than what it has been hyped up to be.
Sony officially revealed the PS3 and for the first time at E3 2005, and claimed that their Cell processor would be capable of 200 GFLOPS.
One may wonder how they got that figure? IBM's own white pages:
http://www-128.ibm.com/developerwork...ca=drs-#table4
As seen from the link (in Figure 5) the Cell has a theoretical peak of 201 GFLOP’s– running 8 SPE’s at 25.12 GFLOP’s apiece (Table 2). This is where Sony gets their 200 GFLOP figure from.
When physically tested however, only 155.5 GFLOP’s were actually achieved (see Table 4) with a total efficiency rate of 75.9%.
Because of manufacturing yield issues, the PS3 will only use 7 SPE’s with the theoretical peak for the PS3’s Cell processor being reduced to 176 GFLOP’s, each running at 25.12 GFLOP’s. Utilizing the same 75.9% efficiency, it is easily interpolated that the PS3’s Cell CPU will only be capable of 133.6 GFLOP’s.
The Xbox 360 has 3 general-purpose 2-threaded CPU's, which generates a proven 115.2 GFLOP’s which is dramatically easier for developers to utilize. By now it should be pathetically obvious that sony is no where near as far ahead as they try to lead you to think (keep in mind they claimed that the ps2 was more powerful than the original xbox, but were proven wrong publicly, since the xbox was indeed twice as powerful). The ps3 will, once you have taken into account thetotal amount of resources that will be used by their respective operating systems, end up with less CPU power available for graphical and physics processing than the 360.

According to the (unbiased) site above, the PS3 will also constantly reserve 1 SPE** for running its operating system. Now that there is actually one less SPE reserved for gaming purposes, it is definite that the ps3’s cell will only be capable of 114.4 GFLOP’s for the purpose of game processing.
**SPE’s are floating point processors, they are also called DSP’s, and SPU’s. These floating point processors are NOT to be confused with cores, cores have far more prediction and calculation braches than floating point processors. As stated earlier, the 360 has 3 cores, each running at 3.2GHz, with 2 threads each. The cell also runs at 3.2GHz, but is the one and only core that the ps3 has.
