Good precautions. -Wear a hazard suit. Not unlike the one gordon freeman wears. -Carry a crowbar. If it doesn't hurt you it's probably good for something -Always prepare to fight the mob... They will come and you never know which one either -Always put "in my opinion" when you write something. It's not a safeguard and it could still alert the mob, but it increases your chances of passing by the witch unnoticed.
I hope these instructions will help you on your continued journeys.
@selnor So you agree that the ps3 has the edge. That's good. I wish you would have told me right away.
See, the cell actually has a peak performance closer to it's theoretical one than the 360 does, and it's ability to perform so many tasks at once is something that greatly increases its flexability. Now i'm not interested in re-igniting this debate. I'm really not. But while it takes a heavy load on the 360 to calculate such things as physics, it's a breeze to throw all of those over to one of the spus in the ps3. And that's just one example. And that's where the ps3 shows it's true potential and manages to move around potential bottlecaps.

I actually believe they are pretty much on par. For a start they are closer tha PS2 and Xbox 1.
And Cells peak performance is nowhere near it's theoretical.
Taken directly from IBM's full test of Cell running 8 SPU's
Table 4. Performance of parallelized Linpack on eight SPUs
| Matrix size | Cycles | # of Insts. | CPI | Single Issue | Dual Issue | Channel Stalls | Other Stalls | # of Used Regs | SPEsim | Mea- sured | Model accuracy | Effi- ciency |
| 1024x1024 | 27.6M | 2.92M | 0.95 | 27.9% | 32.6% | 26.9% | 12.6% | 126 | 83.12 | 73.04 | 87.87% | 35.7% |
| 4096x4096 | 918.0M | 1.51G | 0.61 | 29.0% | 56.7% | 10.8% | 3.4% | 126 | 160 | 155.5 | 97.2% | 75.9% |
Notice the model accuracy is 97.2% and the efficiency is 75.9% of the theorectical Peak GFLOPS performance. Doing the math brings down the GFLOPS in a contolled environment test to 150 odd GFLOPS. Take away 1 SPE which is not used for games and another which is dorment for OS and we are closer to 120 GFLOPS. Again 120 GFLOPS is in a controlled environment and not in an unstable game code environment.
This is directly from the link you posted in this thread. These figures will never change, unless Sony changes the CPU in the PS3. And that doesn't happen to consoles. Dont get me wrong both consoles are powerful but not nearly as powerful as PR BS portrays. It's like TRE. You cannot forget when Cell is doing Graphics it CAN'T be doing normal CPU work. So devs have to be careful how much CPU work time they take away from Cell.
Likewise the same is said for 360. There is just a different set of boundaries for that machine.
