Power consumption on various versions and revisions of Athlon 64

I'm thinking of getting an Athlon 64, maybe the 3000+ or 2800+

I prever lower wattage both to save power, and to run quieter
(fewer/slower fans).

Looking at wattages

Athlon 64
(1.8GHz) 1.4V
(?V~?V) ?V 45.6A 66W 70° C
Athlon 64
(1.8GHz - rev. CG) 1.3V
(?V~?V) ?V 36.8A 50W 70° C
Athlon 64
(2.0GHz - rev. C0) 1.4V
(?V~?V) ?V 48.4A 70W 70° C
Athlon 64
(2.0GHz - rev. CG) 1.4V
(?V~?V) ?V 47.7A 69W 70° C
Athlon 64-2800+
(1.8GHz - 512KB) 1.5V
(?V~?V) ?V 57.8A 89W 70° C
Athlon 64-3000+
(2.0GHz - 512KB) 1.5V
(?V~?V) ?V 57.8A 89W 70° C


I am confused among the terms "Revision CG", "Clawhammer," and "Newcastle."

I assume that nice little 50W 1.8GHz model is a "Mobile" chip, correct?

And then on newegg.com I see a 35W, 1.2V 2800+ (1.8Ghz?) model
http://www.newegg.com/app/ViewProductDesc.asp?description=19-103-448&depa=1
whereas all of them on the chart are at least 1.3V.

All of them, including the Mobile models, are apparently Socket 754, so
are they all compatible with every Socket 754 motherboard?
(I look at the available voltages on a desktop motherboard and see
"Normal, not adjustable" so perhaps not.)

Also are Mobile chips slower, e.g. is a "Mobile 3000+" slower than a
"3000+"? It's hard to find benchmarks of the Mobile chips where they
compare directly to desktop chips.

Basically I just want to know what are the lowest 2800+ or 3000+ Athlon
64 that will work in a desktop model, and how to ask for them.

Thanks!

The authoritative document is available on AMD's website:

You can find specific ordering part numbers.
