Why Did Intel Have A High 800MHz CPU FSB And Now A Low 100MHz??

[melikepie]

Im used to the AMD 200MHz FSB but why does intel make a really high one and now low?

FSB doesn't exist anymore. bckclk is something else entirely.

What's bckclk?
What's the difference between FSB and bckclk?

BCLK is Base Clock and it's so named because it's just that: the Base Clock for everything. That's why you can't really OC the BCLK much on SB and IB because there's no way to unlink the BCLK from the PCI/PCIe and SATA bus speeds.
