Antminer E9 Pro vs Antminer K7
Side-by-side specs, profitability, and home mining comparison.
Quick verdict
The Antminer E9 Pro (3,680.0 MH/s, EtHash) and Antminer K7 (63.5 TH/s, Eaglesong) mine different algorithms and cannot be compared head-to-head — Different algorithms make direct comparison impossible — choose based on your target cryptocurrency.

Profitability Comparison
Bitcoin (SHA-256) profitability math does not apply here: the Antminer E9 Pro mines EtHash and the Antminer K7 mines Eaglesong. Daily revenue for each depends on its own coin's network difficulty, block reward, and price — not on Bitcoin difficulty — so a single BTC calculation cannot compare them.
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 E9 Pro 29% better power draw (2,200 vs 3,080 W)
- 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 38% more score de minage domestique (11.0 vs 8.0)

Foire aux 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.
