For a few months, we’d been hearing talk of a new dedicated Intel processor for MIDs (Mobile Internet Devices), intended to compete with ARM processors. Initially known by the names Silverthorne and Diamondville, the processors in this new line will be called "Atom". These chips have a few surprises in store.
Interesting and Surprising Choices
Atom CPUs are surprising for more than one reason: they have modern functions (EM64T, SSSE3, etc.) grafted onto an older architecture The Atom is the first in-order x86 since the Pentium. Power management and fabrication costs are the two imperatives Intel seems to have been guided by, at the expense (with no attempt made to hide it) of performance. So, no, don’t expect a competitor to Core 2 Duo. But what does the Atom really have to offer? We’ll see that as this piece unfolds.

Biased much?
His point was that it's not only less powerful than "comparable" desktop CPUs, it also takes more power, which pretty much defeats the meaning of being used as a CPU in portable applications. His point is that this CPU is unimpressive in every area you could apply it versus what's already there. Nice try, Intel.
Don't get me wrong...I do think the Atom probably has a decent performance per watt for the CPU itself, but this platform being tested, the entire rig, is where it disappoints. I don't know if it's all in the PSU inefficiency or what, as Anandtech's review of the ASUS Eee Box put power consumption at below 20 watts under load, using a seemingly comparable hardware list (but with a DC power brick, instead of a conventional power supply).
Still don't know if it's POSSIBLE to run Vista64 on a Atom.
I'll wait for the next-gen of eee PC clones. Then I'll get a better idea of real-world performance.
It would be interesting to see their response at the Intel Atom Processor Launch Event on June 3rd, 2008*. In the meantime, let's take a look at what the NVIDIA Tegra is all about... why ? lets see
* an 800 MHz ARM CPU,
* a HD video processor,
* an imaging processor,
* an audio processor,
* and an ultra-low power GeForce GPU
