Sun is playing the eco card with its latest processor, flaunted as the most eco-responsible chip ever.

The UltraSPARC T1 is a little different to your average commercial CPU. Look at AMD and Intel's server chips and you'll see one or two cores, with each of those cores dealing with one or two threads simultaneously. Sun's latest chip, using CoolThreads technology, incorporates up to eight processing cores, each capable of dealing with four threads simultaneously.
