What is difference between FSB Speed of CPU and FSB Speed of Motherboard
Posted on 2005-04-14
This question is more academic in nature as opposed to any application motive. Lately, I have been working with motherboards more so than usual which has naturally sparked my curiousity on some things. One thing in particular which I find somewhat confusing relates to FSB or Front Side Bus Speed. For instance, what is the difference between FSB of the CPU and the FSB of the Motherboard? With my current setup, the FSB of my processor is 333, so, I had to use a jumper to set my motherboard FSB speed to 166 because the FSB speed of the processor is always 2X more than the motherboard for Athlon chips as explained by an expert from a previous post. In any case, I am just curious about why there is this difference? Does it have anything to do with the processor being inherently faster than the motherboard?
Any shared insights on this post will be appreciated.
