[Hidden-tech] ruggedized AMD processor speed limitation question

[Matt Lampiasi]

I'm not a hardware expert either but have tested various low power cpu's 
as that can be the crux of power savings in a pc.  I'm not familiar with 
the geode but I can tell you the MHZ speed is far from the end-all in 
comparing performance. unfortunately seeing is the best test. If you 
can't do your own, try to find benchmarking tests (maybe online, 
someplace like tom's hardware), if you can find your processor reviewed 
they often show exactly what you're looking for: performance during 
various tests, including video.

Checkout VIA processors as well, they are renowned for their low power 
capabilities , and a 1ghz model ive owned played back video extremely 
well, with very low wattage.  I'm not aware of any systems using this 
processor in the same format as the system you mention (though i havent 
looked)

I took a look at their site, those are interesting computers, the flash 
models will use less power, and running with wireless off (if thats an 
option) will also extend battery life. Sounds like you need to get one 
for testing as its a fine line between performance and conserving power.
