AMD Sempron processor family is a new budget line of AMD processors that
superseded AMD Duron family. AMD Sempron
family is based on two architectures:
- K7. All K7-based processors are compatible with socket 462 (socket A).
- K8. These Sempron processors use socket 754 and may or may not have
64-bit mode enabled.
This page describes only Sempron processors based on K7 (Athlon) architecture.
Despite being advertised as budget line of AMD processors, Sempron socket A
processors are simply re-branded Athlon XP processors. Unlike the Duron
processors, that had some CPU features crippled, the socket A Semprons
have all of the features of Athlon XP CPUs.
All Sempron socket A processors have 333 MHz (166 MHz DDR) bus speed and
are manufactured on the 0.13 micron technology.
Similar to Athlon XP processors, all Sempron processors are marked with rated
speed. AMD Semprons are rated differently from Athlon XPs - while the XP
processors are rated relatively to Pentium 4 family, all Semprons are
rated relatively to Intel Celeron CPUs. For relationship between
rated and actual frequency of Sempron microprocessors please see
AMD Sempron identification page.
