The Artigo used only 14W idle and just above 20W on full load measured from
the wall. Suspend-to-RAM however did not function properly — the system's
fan continued to be active after being put into Standby, and power consumption
was an unusually high 8W.
Video playback was abysmal. The system failed to render any of our standard
test clips properly, no matter what combination of players, codecs, and filters
were used. They all exhibited significant stuttering, out-of-sync audio and
dropped frames, making them unwatchable. As the onboard graphics does not support
hardware acceleration for H.264 or VC1 content, these clips were rendered primarily
by the C7 1GHz processor, which proved inadequate.
The Artigo's performance and power draw was compared with two low power computers based on the Intel Atom 270 processor.

Compared to Intel Atom based PCs with similar hardware (5400 RPM
hard drive and 1GB RAM), the Artigo's low power draw suddenly doesn't seem so
amazing. The (Atom 270 based) Eee 1000H laptop was more power efficient, especially with the CPU under load. The Eee Box, required about two watts more on average. Keep in mind, both Eee's have to power
extra peripherals including a WiFi adapter and memory card reader. In addition,
both Eee products successfully rendered our H.264 720p video test clip, something the
Artigo failed to accomplish.
