As I've mentioned here last week, I'm installing
Debian on an Atom based system to replace
a PIII and Sun Ultra 1 at home.
Here are some wattage comparisons measured with
Kill A Watt.
PIII dual 550 Mhz with 2 320 GB IDE seagate drives
Idle: 53 watts
Typical load: 86 watts
Sun Ultra 1 167 Mhz with 2 18 GB 10K SCSI drives
Idle: 94 watts
Typical load: 104 watts
Atom 1.6 Ghz with 2 320 GB SATA seagate drives
Idle: 42 watts
Typical load: 47 watts
The Atom motherboard and processor is a funny setup.
The heatsink and fan are over the main chipset, and there
is a tiny passive heatsink over the CPU. Quiet the twist
on what we're used to seeing.
Part of the reason I kept the PIII system for so long was
that it just worked, and it was cheaper on power than
any upgrade path previously available.
