Bitaxe Gamma vs. Antminer S19 XP: The Honest Comparison 2026

By Dominik Lederer, Founder, Hardware Engineer & Solo Mining Expert · Updated August 10, 2026

What is the Antminer S19 XP and why is it compared to a Bitaxe here?

The Antminer S19 XP from Bitmain is an industrial machine. According to official manufacturer specifications on support.bitmain.com, it delivers 141 TH/s with three percent tolerance, drawing 3,031.5 W with five percent tolerance, thus achieving 21.5 J/TH.

The Bitaxe Gamma 601 comes from a different world. 1.3 TH/s, 17 W, 13.1 J/TH. It is arithmetically 108 times slower and yet the more efficient chip per terahash. That's precisely what makes the comparison interesting. Anyone who wants to solo mine at home isn't asking which device delivers more hashrate, but rather which device they can afford without the electricity bill becoming a family issue.

What does the Antminer S19 XP really cost per year in electricity?

This is where it gets unpleasantly concrete. 3,031.5 W in continuous operation results in 26,556 kWh per year. At 0.35 euros per kilowatt-hour, that's about 9,295 euros. Per year. Only for electricity, excluding purchase, cooling, or electrician.

For context: The S19 XP draws many times what an average German household consumes in an entire year. This is the real reason against this device in a residential space, not the noise, which is most loudly discussed online. Yes, the S19 XP, as an actively cooled industrial ASIC, is significantly louder, but the circulating numbers from forums are fictional. The consumption, on the other hand, is measurable.

The Bitaxe Gamma 601 is at 17 W, which results in 148.9 kWh and about 52 euros per year. Not zero euros, no one claims that here. According to product data, the device operates between 15 and 19 W, depending on the load.

Who has the better chance of finding a block?

Clearly the S19 XP, without evasive maneuvers. At the current difficulty of 127,479,855,693,691, its statistical chance of finding a block is about 1 in 123 per year, while the Bitaxe Gamma 601's is about 1 in 13,355. Anyone who claims a 17-watt device has the same chance as a 3-kilowatt monster is talking nonsense.

The block yields 3.125 BTC plus transaction fees. At an exchange rate of 56,404 euros, that's about 176,300 euros, depending on the exchange rate, as of August 10, 2026. Anyone who reads figures beyond 300,000 euros is calculating with invented exchange rates.

In terms of statistical annual return, the S19 XP comes to about 1,431 euros, the Bitaxe to about 13.20 euros. When calculated against electricity costs, the picture changes: 6.5 euros in electricity per euro of expected value for the S19 XP, 3.95 euros for the Bitaxe. Both are a losing proposition, but the large miner loses dramatically more in absolute terms.

What do the numbers look like in direct comparison?

Criterion	Antminer S19 XP	Bitaxe Gamma 601
Hashrate	141 TH/s (±3 %)	1.3 TH/s
Power consumption	3,031.5 W (±5 %)	17 W
Efficiency	21.5 J/TH	13.1 J/TH
Annual electricity costs	approx. 9,295 Euro (26,556 kWh)	approx. 52 Euro (148.9 kWh)
Block chance per year	approx. 1:123	approx. 1:13,355
Ratio of electricity costs to yield	6.5 to 1	3.95 to 1
Suitability for residential use	no, technical room or hall needed	yes, desktop operation
Purchase price	market-dependent, mostly used market	129 Euro (Snowstorm Edition)

Why is the Bitaxe still the better device for home use?

Because solo mining at home is not a profit project, but a lottery ticket with a learning effect. If you accept that, you no longer ask how high the chance is, but how expensive the ticket is.

The Bitaxe Gamma 601 costs 129 euros in the Snowstorm Edition, power supply, 3D stand, and OLED display included. It runs on the desk, draws less power than an old light bulb, and costs around 52 euros per year. The display shows what the device is currently doing, and you learn about Stratum, Difficulty, and Pool configuration in practice.

The S19 XP, on the other hand, needs its own power circuit, exhaust air routing, noise protection, and an environment where no one lives. Anyone who has that usually mines in a pool anyway instead of solo. For residential use, it is simply the wrong tool.

For whom is which device worthwhile?

The Antminer S19 XP is only worthwhile with electricity significantly below the German household tariff, with a technical room and in a pool instead of solo. At 0.35 euros per kilowatt-hour, it is a guaranteed loss-making venture.

The Bitaxe Gamma 601 is worthwhile if you want to understand Bitcoin, support the decentralized network, and keep an honestly small chance of finding a full block: 3.125 BTC plus transaction fees, without a pool, without share calculation. Unlikely, but not a marketing promise, but the way the protocol works.

A miner that consumes more electricity than the entire household will not win an argument at the dinner table. Honest solo mining begins with knowing the price of the ticket.

Can a Bitaxe really find an entire block?

Yes. Any solo miner with a valid connection to the network can find a block and then receives 3.125 BTC plus transaction fees. With the Bitaxe Gamma 601, the chance is approximately 1 in 13,355 per year. Small, but not zero.

Is the Antminer S19 XP louder than a Bitaxe?

Significantly. The S19 XP operates with high-pressure fans for about 3 kilowatts of waste heat, the Bitaxe with a single small fan for 17 W. Specific multiples circulating online are not substantiated. The exclusion criterion for residential use is, in any case, power consumption.

Is solo mining in Germany even profitable?

As a profit model, no. Both are in the red, the S19 XP significantly more so with 6.5 euros in electricity costs per euro of expected value than the Bitaxe with 3.95. Solo mining at home is a deliberately purchased lottery ticket.

What happens if the difficulty increases?

The block chance of both devices decreases proportionally, while electricity costs remain the same. Every upward retarget equally worsens the ratio of costs to expected value for both.
