AMD Sempron microprocessor family

• K7 microarchitecture. All K7-based processors have the same features as other desktop K7 processors, and work only on socket 462 (socket A) motherboards.
• K8 microarchitecture. K8-based Sempron processors require socket 754, 939 or AM2 motherboards, and include many new features that were introduced by K8 microarchitecture. To distinguish these CPUs from K7-based Semprons our site refers to them as "Sempron 64", although technically this name is not correct.

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.
