AMD will roll out more than one Athlon XP chip based on the new core, including one chip running at 1.8GHz with a performance rating of 2200+, said an AMD product manager.
Previously, AMD's fastest Athlon XP had a performance rating of 2100+.
Over time, the Thoroughbred core will replace the 0.18-micron Palomino core in processors running at lower clock speeds, as existing stocks of those chips are sold. "We don't want to cannibalise our Palomino business," the product manager said.
The 0.13-micron process that is used to produce Athlon XP chips with the Thoroughbred core offers several benefits over previous versions of the processor.
The more advanced process allows the chips to run at higher clock speeds while consuming less power.
In addition, the size of the chip's die can be shrunk using the more advanced process, allowing AMD to produce more chips on each wafer, resulting in lower unit costs.
