I don't believe in benchmark numbers. They are often just
synthetic without real-world relation, and often they're
Instead, I compare by the speed of real-world tasks, like
compiling sources, which I need to do quite often, so it's
an important thing to compare for me personally, or how
much CPU percentage a media player requires.
With such kind of real-world tasks, my 1000 MHz C3 is
significantly slower than my 800 MHz Pentium-III, but just
a little faster than my 466 MHz Celeron and a friend's
450 MHz Pentium-II. That's why I say it is close to a
Regarding power consumption: The complete mainboard with
the 1 GHz C3 (an EPIA PD10000) consumes 15 W when idle,
and not much more when under full load. That includes
onboard components like graphics adapter, audio, USB etc.
I'm currently considering to buy an ARM-based board (for
different purposes). There are some supported by recent
patches to 7-current. They consume only 1 to 2 W, but are
also a little slower than the C3. However, I haven't found
one yet that contains the onboard components that I need.
