Actually, tests done by Tom's Hardware Guide suggest that overall the
Core 2 is a more efficient chip than the Atom. It's just a case of
paring it with the right hardware.

From what I understand these 'crippled' chips are basically the higher
end chips which don't at full spec, for instance a Celeron Dual Core
could well be a Core 2 Duo which a section of cache on doesn't work.
Rather than just chuck the chip away they disable some of the cache and
sell it on as a cheaper part. AMD do the same with the Phenom X3 (and
newer Phenom core based Athlon X2's) where they disable a faulty core
and sell them as a slightly cheaper chip. To be honest considering what
sort of financial state AMD are in at the moment they need to do this to
recoup some of the costs and pay off some of the debts.
There is also the fact that if you're so inclined it is possible to
overclock some of these chips (especially the Celeron Dual Core and
Pentium Dual Core) to much faster speeds. I managed to get about 3GHz
from my 1.8GHz Pentium Dual Core, sods law though the power saving
driver in Linux clocked it back to it's original speed.

Technically last year's model would be the Athlon X2 which they are
still selling as an Athlon X2, albeit fairly cheap although I'm yet to
see any Sempron X2's in the shops (IIRC they do sell them in very small

Actually the Phenom II is starting to claw back some of the
performance. Considering if you have an AM2+ board you can drop in a
Phenom II X4 straight onto the board that is a pretty good performance
upgrade especially compared to the new Core i7 which needs a new board
and DDR3 memory (and if I'm correct they are replacing the socket on the
Core i7 again later on this year). If you were to stick an AM3 CPU on
an AM2+ board then you have extra future proofing as you can upgrade to
an AM3 board and DDR3 memory when the prices come down.
