The Athlon XP processor uses a nine-stage, superscalar pipelined CPU core to process more
instructions in a given clock cycle than other x86-type processors. Optimized for the Windows XP
operating systems, the Athlon XP processor is also compatible with all earlier Windows operating
systems (Windows 2000, ME, and 98). These systems use the Socket-A method of processor
mounting as shown in Figure 2-7.
