Sempron processors based on socket 462 are, in fact, Athlon XP processors with a 333 MHz external bus (166 MHz transferring two data per clock cycle) and 256 KB of L2 memory cache (or 512 KB on 3000+ model). Click here for a full comparison between socket-462 Sempron and Athlon XP.

This Sempron line has the same features of Athlon XP processors, like:

• 64 KB instruction L1 memory cache and 64 KB data L1 memory cache.
• 256 KB or 512 KB L2 memory cache.
• Support for MMX, 3DNow!, SSE and SSE2 instructions (no SSE3).
• 130 nm manufacturing process.

In the table below we list all Sempron socket 462 models released to date. TDP stands for Thermal Design Power and indicates the CPU maximum thermal dissipation, i.e. the CPU cooler must be able to dissipate at least this amount of heat.
