Affiliate disclosure. Mini-PC Index intends to earn
commission from links to vendors. No affiliate programme is configured yet, so every
outbound link on this page is a plain, untagged vendor link and earns nothing. When that
changes, commissions will never affect which machines are listed, what the data says, or how
the table ranks.
What the data says
Everything below is computed from the table — no opinions, no hands-on testing. Each row links to the source of the measurement it rests on. Where a machine is missing from a list, it is because a value it needs is unknown, not because it was judged and excluded.
Performance per watt
Cinebench R23 multi-core score divided by the reviewer's measured maximum load draw. Only the 185 machines with both a benchmark and a measured load figure can appear.

Lowest measured idle draw
The number that decides what a 24/7 machine costs to own. kWh per year is simply the idle figure × 8,760 hours — arithmetic, with no electricity price assumed.

Credit where it is due. We do not measure power. These are other
people's measurements, aggregated with attribution. IdleWatt
runs its own Kill A Watt bench and publishes a measured idle database with a stated methodology —
if idle draw is the only thing you care about, go and read them too.

What changes if you care about idle draw
Rank each machine by raw multi-core score, then re-rank by score per watt of measured idle draw. The machines that fall furthest are the ones whose speed you pay for around the clock.
