"bus speed", "rated bus speed", "stock bus speed"

Question

I was wondering what are differences between "bus speed", "rated bus speed", "stock bus speed"?

I saw in Speccy running on my laptop:

Bus Speed 200.0 MHz
Rated Bus Speed 800.1 MHz
Stock Core Speed 1600 MHz
Stock Bus Speed 200 MHz

Thanks!

Answer 1

Stock Bus Speed 200 MHz

Default Speed at which Front Side Bus aka FSB aka bus runs at.

Bus Speed 200.0 MHz

Speed at which Front Side Bus aka FSB aka bus runs at.

Rated Bus Speed 800.1 MHz

Effective speed of the bus ( recent Intel chipsets are quad pumped, hence 200MHzx4 = 800 MHz)

Stock Core Speed 1600 MHz

Stock speed of your processor core.

( If you're wondering why "stock speed" v/s just "speed" - speed would refer to the overclocked speed ).
