Equihash comparison
Bitmain Antminer Z15 Pro vs Bitmain Antminer Z15
The Bitmain Antminer Z15 Pro is 17% more efficient per KSol, which is what decides the break-even electricity price below. Both machines are modelled with identical assumptions and your own rate.
Side by side
| Measure | Antminer Z15 Pro | Antminer Z15 |
|---|---|---|
| Hashrate | 840 KSol/s | 420 KSol/s |
| Power draw | 2,500 W | 1,510 W |
| Efficiency | 3.0 W/KSol (better on this measure) | 3.6 W/KSol |
| Revenue / day | $0.000214 | $0.000107 |
| Electricity / day | $3.60 | $2.17 |
| Operating profit / day | -$3.60 | -$2.17 (better on this measure) |
| Operating profit / month | -$107.99 | -$65.23 (better on this measure) |
| Break-even electricity | $0.000004 (better on this measure) | $0.000003 |
| Cooling | Air | Air |
| Home suitable | No | No |
Both machines assume a 1% pool fee at the current ZEC price and network difficulty, running continuously. A highlighted figure is the better of the two on that measure — marked only where one genuinely is better, not on hashrate, power or revenue, which reflect the size of the machine rather than its quality. Highlighting is not a recommendation, and no manufacturer pays for placement here. Your rate is saved in this browser and applies across the site.
Our view
Bitmain Antminer Z15 Pro
840 KSol/s · 2,500 W · 3.0 W/KSol
Equihash hardware is a thin market with few buyers, so resale is harder than for SHA-256. Treat the payback figure as less reliable than the headline suggests.
Bitmain Antminer Z15
420 KSol/s · 1,510 W · 3.6 W/KSol
Half the hashrate of the Z15 Pro at around 60% of the power. Aging hardware on a niche algorithm — a speculative purchase rather than an infrastructure one.
These are editorial judgements, not paid placements. Neither manufacturer has any influence over the ordering or the verdicts, and no purchase links on this page are affiliate links. Purchase price, warranty and availability are excluded because we do not yet publish a verified retailer feed — a comparison that invented them would be worse than one that omits them.
