Guess you haven't heard of DMA?

LOL, I worked with dma back in the early eighties.

I agree that much of the disk IO is through the dma channel so in the Intel case through the northbridge and in the amd case through the crossbar; let's say that cancels out. All the other IO makes the intel fsb choke (including the IO commands to the hd) and not reach full bandwidth for memory. Which is not the case with the amd hypertransport io system.
