Note: This box is NOT ATom based. Its Core Duo based.
Which frankly, should make it a lot faster than an Atom (even a dual core Atom).
The Atom processors currently out (to my knowledge) are all 1.6 GHz, and are more like a "souped up" Pentium processor (built on more advanced manufacturing techniques) than a Core Duo. Which is why they consume FAR less power. ie: a single core Atom (CPU only) consumes about 4 W of power (FOUR) and dual around 8 W. (its the Intel 945 chipset responsible for the board overall going much higher).
At the moment, there are only 3 Atom processors available, and all MUST be purchased with a motherboard (I believe they're all soldered in). These are:
Atom 230 - single core 1.6 GHz - designed for desktops/nettops.
Atom 330 - DUAL core 1.6 GHz - designed for desktops/nettops
Atom 270 - SINGLE core 1.6 GHz - designed for notebooks/netbooks
And supposedly an Atom 280 is coming out shortly - again for notebooks, its a tad faster (barely) at around 1.65 GHz (if I remember correctly), and I think is more tied to a new chipset.
The 230 and 330 come on boards today with one chipset choise - the INtel 945GC which consumes a bunch of power by comparison.
The 270 typically comes with the Intel GMA 950 chipset.
I did see a few higher priced machines out there with the Z520 or whatever AToms (1.33 GHz and 1.6, all single core), can't remember the difference here, but these aren't the mainstream Atoms.
Just wanted to clarify. The Everex machine mentioned should probably spank up on an Atom quite handily I would guess.
