Sony said PS3 will be twice as powerful as Xbox 360
"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.
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.
http://ps3.qj.net/Inside-the-PS3-s-O...g/49/aid/21047 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."
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).

Remember the Xbox 360 also has part of the processor reserved for OS functions. In addition to this, its probably easier to devote one whole thread/processing element to a problem than to share execution resources and potentially conflict, in addition to this the Cell CPU probably makes better use of each execution unit due to the cache/streaming architecture. So I suspect the achieveable performance for the PS3 is about spot on whilst the Xbox 360 is a little over-exagerated there.

PS3 does 114.4 Gflops while in game.
360 does 115.2 Gflops while in game.
360 Xenos is more powerful than the Cell.
|
I don't see them making the same considerations for OS etc on the Xbox 360 nor any idea of how they actually tested the consoles.
|
They tested the "Full" power of the Cell and Xenos, they are shown above. Xenos is slightly better than the Cell.
360 OS uses less RAM and the 360 RAM can be shared so again the 360 is superior.
|
no..it's not. for one they make many guess.
and IBM say's otherwise, you know the one's who made both processor's.
|
What "Guesses" have they made?
And IBM said "theoretically" the Cell was better than Xenos when it was tested it wasnt.
|
I call bull sH!T. why because their so call proof is a guess:
this is the first line:
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.
bull shit, it's it's the same d@mn processor that was in the high class server's.
9 cores
1 disabled IE: the 8th core spe was for redundance IE meshed era redundance. IE the d@mn security vault.
so it's not considerably less powerful, it is just as powerful.

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.
where IBM states it's
the xbox360's processor does 77 GFLOP's

again rage 3d claim's
**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.
where as the people who designed the d@mn processor who have PHD's, many year's experience in chip design
call it what they are
Core's
you cannot be a multiple-core design with only one core
Basic Processing Element(s)
Cell is composed of nine processing elements: a standard PowerPC core, and eight SIMD cores. In addition, there is a dual XDR memory controller, and two I/O controllers. The processing cores, as of rev3, run at 3.2GHz.
Program Model
Two seperate programs are written. First, the explicitly software controlled memory SPE program is written. It may be necessary to use intrinsics in the inner loops to fully exploit the SPEs computational capabilities. The SPE program is then embedded within a standard PowerPC program. The PowerPC program creates SPE threads passing a pointer the embedded SPE program to them. All 10 threads operate independently, and are explicitly synchronized by the programmer.
ps:
On development for Rage. "...and we're trying to say pretty plainly that this is going to be the one thing that the PS3 version is gonna be better at, and in fact it's almost the worst sort of thing for Microsoft there because we are having to work twice as hard on the PS3 to bring it up to spec. But in the end it's going to be 60fps game, and it's going to wind up looking just like the 360, we just had to sweat lot more for it. And if it winds up getting a benefit because of the blu-ray and having the better compression on there, then it's going to wind up looking like the PS3 was the better machine, even though it really wasn't...

please..please Microsoft if I say good thing's reduce the Licence fee's on multiple-disc's
