"Marketing talk says that PlayStation 3 will be 50 times faster than PlayStation 2. It is undoubtedly significantly faster (more likely by orders of magnitude) than Apple's new Core Duo systems."
Now that, I really doubt. You're saying that the PS3 will be at least 100 times faster than Apple's new systems (one order of magnitude is 10 times faster, two orders of magnitude is 100, etc.)? If the PS3 is 50 times faster than the PS2 (likely an exaggeration in itself), then the PS2 must be at least twice as fast as Apple's new systems. I really don't think so.
Perhaps you meant to say the PS3 will be several times faster than Apple's new Core Duo systems? Even that might be an exaggeration, but we will have to see.
