The question behind ASIC Miner Efficiency Explained becomes easier to answer when hashrate is examined separately from power draw and efficiency ratio.
Hardware comparisons should use wall-power measurements, stable operating conditions and the same hashrate interval. Nameplate specifications are a starting point rather than a substitute for measured performance.
Hashrate
When reviewing hashrate, preserve the raw observation before creating an average or percentage. A raw record makes later troubleshooting possible and shows whether a change coincided with power draw. Note configuration, network or environmental events that occurred during the same interval.
- Evidence: a dated record for hashrate.
- Cross-check: compare it with power draw.
- Review trigger: repeat the check after a material change affecting hashrate.
Power Draw
A decision involving power draw should include a baseline and a review trigger. The baseline describes ordinary conditions; the trigger defines when the analysis must be repeated. Include efficiency ratio in that trigger when it can materially change the interpretation of power draw.
- Evidence: a dated record for power draw.
- Cross-check: compare it with efficiency ratio.
- Review trigger: repeat the check after a material change affecting power draw.
Efficiency Ratio
Define efficiency ratio before comparing it with hashrate. Identify the unit or rule behind efficiency ratio, capture a dated value where one exists, and state whether the value is measured, calculated or supplied by another party. That distinction determines how confidently efficiency ratio can support the article’s conclusion.
- Evidence: a dated record for efficiency ratio.
- Cross-check: compare it with hashrate.
- Review trigger: repeat the check after a material change affecting efficiency ratio.
