Mobile Thoroughbred & Barton
Announced on March 3rd, 2003, the Athlon XP-M series consisted from 1400+ to 2600+. Later on, AMD expanded the line to 2800+. At first only the 2800+ featured a Barton core, later on AMD decided to make all cores above the 2400+ utilize the Barton core. Along with PowerNow technology, these new mobile processors were the fastest in AMD history. Overclockers picked up on the idea that the standard Socket A/462 mobile processors were the same as the desktop processors in the many aspects. Due to their reduced operating voltage, these processors were the creme of the crop and are still gems to the overclocking community. Many people have achieved 1000Mhz overclocks with these processors.
