I already referred that there is 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. > > > - FChE > _______________________________________________ > Devel mailing list > Devel@lists.laptop.org > http://lists.laptop.org/listinfo/devel >
