Top 500 supers - rise of the Linux quad-cores

"Intel is the main chip supplier in 402 of the 500 machines that made the cut this time around, and 380 of those are using quad-core processors of one generation or another. Unlike AMD's current line of quad-core "Shanghai" and six-core "Istanbul" processors, which plug into existing Rev F system boards, Intel's Xeon 5500s require a box swap from the prior Xeon 5300 "Clovertown" and Xeon 5400 "Harpertown" series.

"There are 42 machines on the list using AMD's processors and 52 using IBM's Power processors, both losing a little ground since the June 2009 ranking. Dual-core processors are still in use on 59 machines (all of the Power5 and Power6 supers on the list are using dual-core chips), and there are only four machines that employ single-core processors in their cluster nodes."
