Profitability Comparison
Antminer E9 Pro
Antminer K7
Based on BTC price of $78,153 and current network difficulty as of May 16, 2026. Actual results vary.
Verdict
Two specialized miners from Bitmain targeting different algorithms. The E9 Pro mines ETC (EtHash) while the K7 mines CKB (Eaglesong). A comparison for diversified mining portfolios.
These miners serve different algorithms and cannot be directly compared on hashrate. The choice depends entirely on which cryptocurrency you want to mine. Both are well-built Bitmain products with similar build quality.
Spec Deltas
The Antminer E9 Pro and Antminer K7 diverge on the metrics below — each gap expressed as a real percentage, not a vague "better":
- Antminer K7 1725443% more hashrate (0.0 vs 63.5 TH/s)
- Antminer E9 Pro 29% better power draw (2,200 vs 3,080 W)
- Antminer K7 100% better efficiency (597,826.1 vs 48.5 J/TH)
- Antminer K7 1% better weight (14.2 vs 14.0 kg)
- Antminer K7 40% more heat output (7,506 vs 10,509 BTU/hr)
- Antminer E9 Pro 11% more home mining score (40.0 vs 36.0)
Cost & ROI Over Time
Sticker price versus what the miner actually earns back: the table below projects cumulative net profit at a $0.10/kWh electricity rate.
| Antminer E9 Pro | Metric | Antminer K7 |
|---|---|---|
| $3,000 | Upfront cost (MSRP) | $3,500 |
| -$5.28 | Daily net profit | -$5.11 |
| -$4,927 | Net after 1 year | -$5,365 |
| -$6,854 | Net after 2 years | -$7,229 |
| -$8,781 | Net after 3 years | -$9,094 |
| Does not pay back at current rates (negative daily profit) | Payback period | Does not pay back at current rates (negative daily profit) |
Projections assume continuous operation, a flat $0.10/kWh rate, and no hardware degradation, pool fees, or BTC price change. Real-world ROI varies.

Frequently Asked Questions
Can either of these mine Bitcoin?
No. The E9 Pro is an EtHash miner (Ethereum Classic) and the K7 is an Eaglesong miner (Nervos CKB). For Bitcoin mining, look at Bitmain's S-series or T-series Antminers.
Does D-Central stock alt-algorithm miners?
D-Central primarily focuses on SHA-256 (Bitcoin) mining but can source and repair miners for other algorithms through its network.
