Review: Antminer E9 Pro 3600 MH/s 2200 W. The most powerful and cheapest miner (€1/MH) on ETHash

How good is the Antminer E9 Pro, Bitmain's miner for the Ethash algorithm? In this 2023 video review (in French), we present the machine, how to get it running, its measured performance and its profitability, then compare it with the other Ethash miners of the time. One question stands out: does its price of about €1 per MH/s make it the best choice?

Video from 2023: the figures below date from that time. See "What about today?" at the end of the article.

Update: Kadena is dead. The organisation behind Kadena ceased operations in October 2025 and KDA collapsed: what this article says about Kadena is no longer relevant.

An ASIC for the Ethash algorithm

The E9 Pro mines every cryptocurrency that uses the same algorithm as Ethereum: Ethereum Classic (ETC), EthereumPoW (ETHW), QuarkChain, Zilliqa, etc.

It shares a common base with other Bitmain models, such as the S19 for Bitcoin, the KA3 for Kadena or the K7 for CKB. The form factor is roughly the same, with one big difference: the E9 Pro is longer. It runs with two hashboards.

• Connectivity: an RJ45 cable is all you need, plus a port for flashing the firmware and a reset button;
• Power: two standard PC power cables;
• Cooling: two fans on one side, two on the other. It is a fairly noisy machine: something to bear in mind before buying.

Getting started

At start-up, the fans spin at 100% and the machine is very loud, then everything settles once the miner is really up and running. You log in to the web interface with the machine's IP address and the root / root credentials, which takes you to the dashboard.

Two things to know:

• Choosing the pool: this is a new model, and not all pools handle it well. We mine on 2Miners, which has a page dedicated to configuring the E9 Pro in its Ethereum Classic section;
• Patience: the hashrate only shows up after 10 to 12 minutes. The machine starts and, for about ten minutes, nothing happens: this is normal.

Measured performance

• Hashrate: 3,600 MH/s, split between the two hashboards at about 1,800 MH/s each;
• Announced power draw: only 2,200 W;
• Temperatures: between 60 and 70 °C on the hashboards;
• Fans: around 3,000 rpm once the machine has stabilised.

Efficiency and price: €1 per MH/s

For comparison, we take the iPollo V1 Mini, a very common Ethash miner: 300 MH/s for 240 W. The E9 Pro draws about ten times as much power; ten iPollo V1 Minis would give 3,000 MH/s, whereas the E9 Pro reaches 3,600 MH/s. It is therefore a little more efficient, but it is no big leap: Jasminer and iPollo machines remain fairly efficient and still profitable.

Its real strength is its price. The 3.6 GH/s version of the E9 Pro was available for about €3,700 including VAT, one of the best prices in our shop, i.e. roughly €1 per MH/s. In France, an iPollo V1 Mini then cost about €950 including VAT for just over 300 MH/s, nearly three times as much per MH/s.

Another plus: its 7 GB of memory leaves headroom for the growth of the DAG. In our view, ETC can be mined for many years with it, at least until 2030 and perhaps longer.

Profitability

At the time of filming, the E9 Pro earned about $337 per month, or about €300 gross. With electricity at $0.10 per kWh, about $180 was left. In euros, that gave:

• at €0.10 per kWh: about €150 per month, i.e. a return on investment of about 24 months, two years in the context of the time;
• with EDF's Tempo tariff (about €0.13): about €100 per month;
• at €0.17, the standard residential rate in France: about €35 per month, i.e. nearly 100 months, over 8 years, to pay back the machine.

On the network side, the Ethereum Classic hashrate, which had climbed to about 150 TH/s, was on a gentle downward slope, at around 100 TH/s. Difficulty had fallen from about 2 P to just under 1.5 P, about 25% lower. It will of course keep changing.

Our conclusion: a really interesting machine, above all for its price. As these figures show, however, its profitability depends heavily on the price of electricity.

What about today?

The earnings, the Ethereum Classic network difficulty and the prices quoted date from 2023 and are no longer current. Before buying an Ethash machine, redo the calculation with today's network data and your own electricity price.
