"Is such a cluster possible? Before we take a look at some real options hitting the market, let's take a look at some numbers. In a recent article at Extremetech, they discuss a paper by researchers at Harvard and Microsoft that seeks to prove that a small, power-efficient core like the Intel Atom chip can be better suited for search applications. The paper is due to be presented at the International Symposium on Computer Architecture in Saint-Malo, France, on June 19.

"According to Extremetech, the paper states that with an average power consumption of 3.2 watts, the Atom (single-core 1.6 GHz Diamondville) is 19.5 times more power-efficient than a Xeon (L5420 quad-core, 2.5-GHz, Harpertown), which consumes 62.5 watts on average. The Xeon, meanwhile, outperformed the Atom by 3.9 times for search tasks."
