Semprons are primarily targeted at the value/low-end segment - they are meant to compete mainly with intels' Celeron D-line, NOT the Athlon XP, Athlon 64 or Pentium 4...consequently, their model numbers aren't meant to be comparable to those of the Athlon XP or Athlon 64-line either.
Obviously, an Athlon XP model 10('Barton'
with 512KB of L2-cache will perform better than a Sempron with only 256KB of L2-cache at the same clockspeed.
The Sempron 3100+ is a totally different story, however - it benefits from nearly all architectural enhancements of the Athlon 64 with the exception of 64-bit capability and some cache - with an integrated memory-controller, Hypertransport-I/O as well as features like Cool'n'Quiet, Enhanced virus protection(Execution prevention/NX) and SSE2-support, it is clearly superior to any Socket A processor.QUOTE
it'd be better to buy an AMD64 3000+ as it's faster and doesn't have 64-bit disabled
You and me and most other people who build a system for themselves would certainly do that...however, in the OEM market where thousands of units are being manufactured and sold, every single cent makes a difference
