Hello, I'm in the process of researching to upgrade a computer with a new motherboard and cpu.
what's the difference when talking about the "front side bus" on the motherboard, and the "bus speed" on the processor?
From what I've learned from howstuffworks.com, the front side bus is the bus between the processor and northbridge. Then what is the bus speed? They say: "Bus speed usually refers to the speed of the front side bus (FSB)". So what they're saying is that: bus speed = front side bus speed.
Howerver, I found another site about bus speeds:
http://www.directron.com/fsbguide.html
They say that "The system clock is the actual speed of your FSB with out any enhancements....The system clock is also sometimes just called the bus speed." They later say: "The Pentium4 3.06GHz processor has a FSB of 533MHz. Its system clock is 533 / 4 = ~133. The multiplier is 3,060 / 133 = ~23.
The AMD Athlon XP2700+ has a main clock speed of 2.17GHz and a FSB of 333MHz. Its system clock is 333 / 2 = ~166MHz. The multiplier is 2,170 / 166 = ~13"
Now I'm getting confused....It sounds like the system clock (which according to them is the "bus speed") is always slower than the FSB.
Here's a mobo/cpu combo at tigerdirect.com:

The FSB on the motherboard is 800mhz, but the bus speed on the processor is 1600mhz. I don't understand what's going on here. Directron.com said that the bus speed is always slower than the FSB.
