Well, basically there are two processors that are both named 'Athlon XP-M 3000+':
The first version is a 'normal' 72W DTR mobile Athlon XP-M, just like the AXP-M 2800+ but with a slightly higher clockspeed(2.2GHz) - it uses the Barton-core(model 10) with 512KB L2-cache.
The second version is currently ONLY available on Compaq/HP Notebooks(to my knowledge).
It uses the Athlon 64-based 'Dublin'-core with 256KB L2-cache.
Architecturally, it's very similar to a mobile Athlon 64, except for the smaller cache, low clockspeed and the fact that it DOES NOT
support AMD64(that's why it's called an 'Athlon XP
This 'Dublin' AXP-M 3000+ uses the same Socket 754 platform as the mobile Athlon 64's, so it could easily be replaced with such a part at a later time.
Also, unlike it's 'Barton'-counterpart, the 'Dublin' AXP-M 3000+ has a max power-consumption of only 62W(vs. 72W for the AXP-M 3000+ Barton).
