This is also referred to, in another thread, but the Atom draws very little
power. I already referred that you can get an Atom that has a 0.65W TDP, not
3.whatever like in the Geode LX. These are the Z series and they draw very
little power, top of 2.4W for the 1866MHz model. The other low-end chip(also
$20), the Z510, has a TDP of 2W - any one of these can run without an
"heatsink", mostly a small metal plate that allows the silicon core to
dissipate heat, since it's a fliped-chip design. The Z500 is obviously very
very good for embedded applications.
The Z series use a lower power CMOS bus, instead of the power hungry GTL+,
which when paired with Poulsbo it should make for a remarkable package. The
next iteration will also have the graphics core and some other stuff
embedded, for further savings.
