Profitability Comparison
Antminer Slim Edition (S9)
PiAxe
Based on BTC price of $78,185 and current network difficulty as of May 16, 2026. Actual results vary.
Verdict
Run the numbers across every spec and the PiAxe edges it: 4 of 6 factors go its way (efficacité, consommation électrique, score de minage domestique, niveau sonore). Where it pulls away hardest is 99% better power draw (1,100.0 vs 15.0 W). The Antminer Slim Edition (S9) claws back ground on hashrate and rapport qualité-prix. The right pick still depends on your power cost and noise tolerance — the breakdowns above make that call concrete.
