Dothan Unleashed : Intel’s Pentium-M Processor On The Desktop
 

Intel currently has two major consumer-level processor architectures on the market, "Prescott" and "Dothan". The Prescott processor core is the basis of Intel's Pentium 4, Xeon. and Celeron processors, replacing Intel's previous mainstream processor core known as "Northwood". Intel's Prescott architecture was truly designed with clock speed scaling in mind, as the chip will scale up to 3.8 GHz, which will no doubt make for some incredibly fast processors. Unfortunately, in order to make these CPU's clock so high, the efficiency of the chip had to be compromised. Intel's "Prescott" processor core runs hotter, consumes more power, and has the worst performance per clock cycle of any modern Intel processor core
