AMD had something to say about Intel’s unpcoming full buffer DIMM’s … they’ll need about twice the power of a DDR stick to run.  As many PC owners have found, the more power you put into a component, the more cooling it requires, and with the heat a Prescott throws out already, these blades will be hot.
“Close chip watchers know that Intel and its OEMs plan to support Fully-Buffered DIMMs in 2007. This memory technology will provide a number of features that should benefit server makers, including high-performance, the ability to spread memory out on motherboards, lower pin counts and better overall reliability. AMD, however, wants customers to know there is a power consumption cost with the technology too. Marty Seyer, a vice president at AMD, warned that the power consumption issues of FB-DIMMs could hurt Intel’s play in the blade server market, during a Merrill Lynch-hosted conference call with analysts and reporters. AMD reckons that a standard DDR DIMM needs 5.4 watts, a DDR2 DIMM needs 4.4 watts and a DDR2 FB-DIMM needs 10.4 watts. Pack a few sticks of memory in a server and that extra load adds up.”
