Just a regular old Athlon 64 underclocked to 1GHz, offers both higher
performance and lower power consumption than Intel Atom systems. A lot
of the efficiency is due to the AMD/ATI 780G chipset, which consumes
just 0.95W! That is compared against the Intel 945GC chipset which used
up a whopping 22.2W!
