AMD Sempron processor family is a budget line of AMD processors that superseded AMD Duron family. AMD Sempron family spans two different micro-architectures:
  • 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.

For averaged multi-threading performance of Sempron CPUs please see AMD Sempron performance pages.

Because AMD Sempron CPUs are rated relatively to Celeron processors, their rating numbers are approximately 300 MHz lower than the rating numbers of Athlon XP processors. For instance, this Sempron 2800+ runs internally at 2 GHz, supports 333 Mhz Front Side bus and has 256 KB of level 2 cache. The rating of this CPU is 200 MHz higher than the rating of Athlon XP 2600+ AXDA2600DKV3D, despite the fact that internal frequency of the XP 2600+ is 83 MHz higher and other features of both processors are the same. If you're looking for an upgrade processor then consider upgrading to Athlon XP processors rather than Sempron CPUs - Athlon XPs may cost less and will be faster than similarly rated Semprons.
AMD Sempron 3000+ - SDA3000DUT4D / SDA3000BOX
SDA3000DUT4D is the fastest officially released AMD K7 Sempron, but not the fastest from all socket 462 microprocessors. Even though this processor has rating 3000+, this rating is relative to Intel Celeron processors and is about 10% higher than Pentium 4 rating that was used for other Athlon CPUs. As a result, this Sempron 3000+ is about as fast Athlon XP 2700+.
Sempron 3300+ is the only Sempron-branded microprocessor with 400 MHz Front Side Bus frequency. Besides branding and 3300+ rating, the CPU is not different from Athlon XP 3200+. Both processors run at 2.2 GHz, feature Barton core with 512 KB L2 cache and 400 MHz FSB, and support 3DNow! professional (3DNow! + SSE) instructions. While the Sempron 3300+ microprocessors were not sold as retail processors and were shipped directly to OEMs, small numbers of these OEM-only parts made it to eBay and online stores.
