Figure 3–2. AMD Athlon XP Processor Internal Architecture and Key Statistics.
The Athlon XP processor uses 0.13 micron technology that yields lower power requirements for a
given processing speed. The system board supports the unit types listed in Figure 3-2.
The Athlon XP processor uses a 133-MHz (on D315 systems) or 166-MHz (on d325 systems)
clock signal for the front side bus. Data transfers are qualified on the both the rising and falling
edge of the clock cycle, effectively doubling the data throughput rate to 266- and 333-MHz.
