AMD Athlon XP microprocessor family
AMD Athlon XP processor family is the successor to the Athlon CPU family. Palomino, the first Athlon XP core, had a few improvements over the previous Athlon core:
All Athlon XP Palomino CPUs had 266 MHz bus speed, and were manufactured using 0.18 micron technology.
Next revision of Athlon XP core, called Thoroughbred, was manufactured on newer 0.13 micron technology, and as a result, had smaller die size and lower power dissipation than the Palomino core. Bus speed of some Thoroughbred processors was increased to 333 MHz.
Bus speed of Athlon XP family was increased even further with the introduction of Barton core. In addition to faster bus speed the Barton core also had twice as much L2 cache memory - 512 KB. Athlon XP Barton CPUs were manufactured on the 0.13 micron process.
Thorton, the last Athlon XP core, was the same as the Barton core with L2 cache size slashed in half - from 512 KB to 256 KB.
Starting Athlon XP family, all AMD processors were marked with rated speed. Please see AMD Athlon XP identification page for relationship between rated speed and actual speed of AMD Athlon XP microprocessors.
