Re:400 MHz, 800 MHz (Score 1)

Your right, MHz. is mostly meaningless. But as far as the bus goes look at it this way.

AMD bus = 200Mhz. x 2 bits per cycle = 3.2GB/s bandwidth
Intel bus = 200Mhz. x 4 bits per cycle = 6.4GB/s bandwidth

You cannot argue that Intel doesn't have an advantage here, having twice the memory bandwidth of the AMD chip.
