I had a lookie at the amd website for the geode and this is what i found.
Quote:
The AMD Geode™ NX processor family consists of three versatile and powerful products - the AMD Geode™ NX 1250@6W* processor, the AMD Geode™ NX 1500@6W processor** and the AMD Geode™ NX 1750@14W processor.***
*This processor operates at 667MHz. Model number reflect performance as described here.
** This processor operates at 1GHz. Model number reflects performance as described here.
*** This processor operates at 1.4GHz. Model number reflects performance as described here.

They compare the chip to the via Nemehiah 1Ghz, not exactly a stellar chip by many standards
Edit - Just reading into the specs a tad deeper the geode looks like an old tbird 'c' built on a .13u process with plenty of mobility tweaks in order to get the power down.
Interesting numbers to compare really is what the dothan does at low power, (ulv versions) and generally when they are in battery mode they are very lean (around 6w)
Edit again
Looking up the TDP for the dothan, at 2.1 ghz the top chip uses 21w.
at 1.5Ghz the low voltage chip needs 10w.
at 1.2ghz the ultra low voltage chip needs 5w!
