AMD Athlon XP 1500+

The slowest Athlon XP desktop model (clocked at 1333MHz and rated 1500+). It runs cooler than the Athlon 'Thunderbird', can process SSE instructions and has a higher IPC (Instructions per Clockcycle). However, an Athlon 1400 can perform better in several situations because the little performance improvements of the Athlon XP can't make up for 66MHz.
