The P4 has a 4X data bus running 200MHz. It then has roughly equal to 800MHz bus, right? Well, Intel says the P4 has an 800MHz FSB
Let's then just call it an "equivalent" amount of bandwidth. Yes, in essence dual channel PC3200 really runs at 200MHz. How much bandwidth does it provide? 4X as much bandwidth as SDRAM running at 200MHz, right? Then, 800MHz worth of "equivalent" bandwidth.
2x12 = 3x8 = 4x6
Don't they all equal 24?
