Athlon XP 1500+ To 2100+: October 2001 To March 2002
The upgrade for the Athlon based on the Thunderbird core came with the introduction of the Palomino core. At the very same time, AMD introduced its revised model numbering system, which no longer related directly to the actual processor speed. Production continued using the 0.18 micron process and the number of transistors now stood at 37.5 million. There were new features, too. The thermal diode was introduced, even though there were no motherboards available to support it at first. From the Palomino core on, the manufacturer equipped the CPU with SSE extensions. There were no changes as far as the cache was concerned.

Athlon XP 1700+ To 2100+: April 2002 To June 2002
With the introduction of the Thoroughbred core "A", AMD reduced the circuit width of its Athlon to 0.13 microns. Maximum thermal dissipation was close to that of its predecessor.
