fsb speed - why does it matter?
it seems to me that nobody needs a high fsb. since they could just
push the multiplier really high. I can see the greatness of ddr since the same speed processor can read/write twice as much per cycle. (i assume that the cpu has to be ddr to receive or write double) |

(i assume that the cpu has to be ddr to receive or write double) How is it you can see the benefit to 'read/write twice as much per cycle' yet not see any benefit to more of the cycles? The CPU communicates to everything through the FSB, and that includes the memory, so the speed of it directly affects how fast the processor can communicate. And since the vast majority of that communication is fetching instructions from memory, it affects how fast it can process them. |

LOL and what about the locked multipliers on the majority of processors? well, AMD can be unlocked. Maybe intel can. They are not really 'locked' they are 'locked' for people that don't know how to unlock them. Just as windows files are 'hidden', it's just a gimmick to make it 'harder'. LOL I fail to see the joke |

And since the vast majority of that communication is fetching instructions from memory, it affects how fast it can process them. The FSB is not THE ONLY THING that affects the speed. The Multiplier*FSB create the speed. The Processor multiplies the FSB, and the RAM multiplies the FSB. I am saying that the multiplier can be increased, so low FSB speed doesn't matter. |

Obviously I see the benefit of more cycles. What do you think I meant when I said "push the multiplier really high". That increases the cycles per second. |
