Depends on the model of Athlon 64.

Power use on Athlon 64's are:

Single core:
89W for 130nm Athlon 64
67W for 90nm Athlon 64
62W for 90nm Athlon 64 (new revision with virtialization support)
89W for FX51/53
104W for FX55/57

Dual core:
89W for some Athlon 64 X2, 110W for others, depending on revision and
speed.
89W for Athlon 64 X2 with virtualization support
65W for Athlon 64 X2 EE (energy efficient models)
35W for Athlon 64 X2 3800+ EE SF (small form factor model)
110W for Athlon 64 FX60
125W for Athlon 64 FX62

So I would think any of the X2 EE models are a good match for the Core 2
Duo on power consumption vs. permance, while the 3800 EE SF needs a
mobile chip to match it by the looks of it.
