Essentially on the desktop side, the Northbridges in Intel motherboards
pull considerably more power than an AMD motherboard does. Nvidia
chipsets are a particularly bad example. I've seen numbers upwards of
50W in some reviews. A typical number I saw thrown around a bit was 20W
for an Intel brand chipset. The typical northbridge on a motherboard
made for an AMD processor uses somewhere below 10W (I can't remember for
sure either, but I vaguely recall seeing even sub 2W numbers -makes
sense: they don't actually need a northbridge). So basically when people
say "I have a 45W proc and yours is 65W, nyah nyah," make sure to tell
them to add the power for the memory controller in the northbridge if
it's an Intel.
