AMD Sempron microprocessor family
AMD Sempron processor family is a budget line of AMD processors that superseded AMD Duron family. AMD Sempron family spans two different micro-architectures:
This page describes only Sempron processors based on K7 (Athlon) architecture.
Despite being advertised as a budget line of AMD processors, Sempron socket A processors are simply re-branded Athlon XP processors. Unlike the previous generation of budget processors, AMD Duron, which had some CPU features crippled, the socket A Semprons incorporate all of the features of Athlon XP CPUs. Sempron socket A processors have 333 MHz (166 MHz DDR) bus speed, 256KB or 512 KB level 2 cache and are manufactured on the 0.13 micron technology. All Sempron processors support SSE instructions.
Similar to Athlon XP processors, all Semprons are marked with rated speed. Sempron CPUs are rated differently from Athlon XPs - while the XP processors are rated relatively to Pentium 4 family, Sempron CPUs are rated relatively to Intel Celeron CPUs. For relationship between rated and actual frequency of Sempron microprocessors please see AMD Sempron identification page.
For averaged multi-threading performance of Sempron CPUs please see AMD Sempron performance pages.
