I recently bought 2 Lenovo S10 netbooks which I use for HD video encoding. It takes 40-48 hours to convert 1 hour of interlaced HDV to 1280x720 on my netbook using virtualdub.

Most atom processors are in netbooks and should be compared with other notebooks or netbooks.

Under full load, only 24Watts and that includes the netbook monitor (which will turn off after a short time).

The beauty of the atom is cheap,efficient horsepower. Instead of 1 fast,expensive video encoding machine, you can buy 2-3 or more atom netbooks. And while one video is encoding, you can start the next video on another netbook.

All those tests which compare total energy usage of the atom versus dual core for encoding are misleading. They are only valid if you immediately turn off the dual core machine when it finishes. If the dual core machine is not turned off, then it will continue to consume energy.

I also have an old quad core desktop pc which encodes 1 hour of interlaced HDV to 1280x720 in approximately 10-12 hours. But my quad core runs 24 hours/day because I use it often. Even if I used it only for video encoding and immediately turned it off after, it will still sometimes finish encoding when I am sleeping or not around. I guess it could be set to auto shutdown after encoding is finished.

An atom netbook at full load easily consumes less energy than most desktop dual core systems at idle. And remember that they usually don't include the monitor in those desktop power consumption tests which can consume significantly more power than a tiny netbook monitor.
