Bitaxe Touch vs Turbo Touch vs Gamma 601: Is the Screen Worth It?
By Dominik Lederer, Founder, Hardware Engineer and Solo Mining Expert at Polarblocks. Network figures read from mempool.space on 5 October 2026 at 07:13 UTC, with the bitcoin price carrying its own timestamp of 07:10 UTC. Turbo Touch figures taken the same morning from the Solo Satoshi product page.
The short version
The Bitaxe Touch is a family of Bitcoin solo miners with a 4.3 inch touchscreen: first single chip models unveiled in January 2025, and since March 2026 the dual chip Bitaxe Turbo Touch from Solo Satoshi in Texas, with open source firmware and board design, which its maker rates at about 2.15 terahash per second and about 43 watts, each within 10 percent.
On 5 October 2026 a Bitaxe Turbo Touch at its stock rating had annual odds of about 1 in 8,407 of finding a block, against about 1 in 13,904 for a Bitaxe Gamma 601 at 1.3 terahash per second. That is about 1.65 times the chance for 2.53 times the electricity: about 131.84 euros a year at a Polarblocks house assumption of 0.35 euros per kilowatt hour, or 139.37 euros at the BDEW average of 37.0 cents, against 52.12 or 55.10 euros for the Gamma 601.
Before any pool fee, the Turbo Touch's expected value of 28.90 euros a year equals 21.9 percent of its electricity at the house tariff and 20.7 percent at 37.0 cents, and at most 7.3 percent of a first year of at least 397.50 euros once its 250 dollar price is converted and import VAT is added, before shipping and customs duty. For the Gamma 601 the same shares are 33.5 and 31.7 percent of the electricity and 9.6 percent of a 181.12 euro first year with the 129 euro Snowstorm edition. The screen adds visibility, not value.
Search for "Bitaxe Touch" and the listings cannot agree on what it is. Two say about 1 terahash per second. Two say 1.6 at 22 watts. The maker itself gives 1.0 for the original and 2.15 at 43 watts for its successor. Two listings name "Bitaxe" as the manufacturer, but Bitaxe is an open source project and a brand, not a company.
I build and sell the Bitaxe Gamma 601, which has a 0.91 inch display, so I have an interest in this comparison and I will show my arithmetic. The Turbo Touch rests on a good idea, and the firmware and board design it runs on are published on GitHub. The question is what that idea is worth in a German living room.
What is the Bitaxe Touch, and how is it different from the Turbo Touch?
The Bitaxe Touch is a desk sized Bitcoin solo miner with a 4.3 inch touchscreen. The original version from 2025 used a single chip and, in later versions, closed source screen firmware. The Bitaxe Turbo Touch, launched by Solo Satoshi in March 2026, uses two BM1370 chips and fully open source firmware.
The story behind the name explains most of the confusion. Matt Howard, who runs Solo Satoshi, writes that he named the device in late 2024 while working with a team in Dallas on the first touchscreen miner, and that Solo Satoshi unveiled it in January 2025. When later versions shipped with screen firmware the community could no longer inspect, Solo Satoshi walked away and built its own.
Solo Satoshi's announcement page lists two original models: about 700 gigahash per second on the older BM1368 chip and about 1.0 terahash per second on the BM1370, each with four screens and a 5 volt supply. The Turbo Touch sits on the dual chip Bitaxe GT 801 platform with a 12 volt supply and eight screens: mining dashboard, block clock, recent blocks, clock, bitcoin price, Wi-Fi, settings and a hashrate graph. The mining firmware is AxeOS, the same software that runs a Gamma 601. The screen runs BAP-GT-TOUCH, published on GitHub.
Two chips explain the jump. The BM1370 is the chip Bitmain uses in the Antminer S21 Pro, and the Gamma 601 carries one of them. The Turbo Touch carries two.
Why do the published specs for the Bitaxe Touch disagree?
The specs disagree because resellers list different generations under one name and copy figures from each other. For a single chip Bitaxe Touch on the BM1370, Solo Satoshi gives about 1.0 terahash per second, while the Kryptex Pool device page and the retailer Bitark both list 1.6 terahash per second at 22 watts. Those figures cannot all be true.
A third listing, at the reseller Crypto ASIC Miners, puts the BM1370 model at 950 gigahash to 1 terahash per second and 17 watts in its table, 22 watts in its title, and gives its efficiency in the wrong unit. So two sources say about 1.0, two say 1.6. I go with 1.0, for two reasons. It comes from the company that sold the device first. And the upstream bitaxeGamma repository derives about 1.2 terahash per second per BM1370 from the 234 terahash per second of an Antminer S21 Pro spread across its 195 chips, with our own Gamma 601 rating of 1.3 already above that. A single chip Touch at 1.6 would run a third faster than the 1.2 the repository derives while also lighting a 4.3 inch screen, and no listing explains how.
The Turbo Touch has a smaller gap of its own. Its product page and Bitcoin Magazine's launch report give 2.15 terahash per second at 43 watts, which divides to 20.0 joules per terahash, and the product page says about 20. Solo Satoshi's announcement page and the same Bitcoin Magazine report say about 18. I use 20, because it is what the two published inputs produce. That announcement page was first published on 12 January 2025 for the original Touch, last updated on 28 September 2026 and now describes the Turbo Touch, which is one more reason the two generations get mixed up.

How do the odds of a Turbo Touch compare with a Bitaxe Gamma 601?
On 5 October 2026 a Bitaxe Turbo Touch at 2.15 terahash per second had annual odds of about 1 in 8,407 of finding a block, and a Bitaxe Gamma 601 at 1.3 terahash per second about 1 in 13,904. The Turbo Touch's chance is about 1.65 times as large, the same as its hashrate ratio, since odds scale with hashrate.
The calculation has three steps. Multiply the difficulty by 2 to the power of 32 and divide by your hashrate to get a mean search time in seconds. Divide by 31,536,000 seconds a year to turn it into years. The reciprocal of that is the annual chance. According to mempool.space, the difficulty stood at 132,716,002,350,731 after a retarget of minus 0.03 percent on 3 October 2026 at 07:16:36 UTC, at block 969,696. That gives the Gamma 601 about 438.5 billion seconds, or 13,904 years, and the Turbo Touch 8,407 years.
Every one of the 52,560 rounds a year, a figure that follows from the ten minute block target rather than from a measurement, plays for 3.125 BTC plus transaction fees. At 77,102 euros per bitcoin at 07:10 UTC on 5 October 2026, the reward alone is worth about 240,944 euros before fees, a figure that moves with the exchange rate. Spread over the mean search time it gives the Turbo Touch an expected value of 28.66 euros a year from the reward and 24 cents from fees, 28.90 euros in total, or 28.32 euros after the 2 percent Solo CKPool charge. The Gamma 601 comes to 17.47 euros, or 17.12 after the fee.
Two forces move those figures this month. Fees, already inside them, add 24 cents for the Turbo Touch and 14 cents for the Gamma 601 on the weekly mean, or 18 and 11 cents on the median. The next retarget, due around 17 October at block 971,712, was projected, as of 07:13 UTC, at minus 1.28 percent with 1,736 blocks still to run, which would lift both expected values by about 1.3 percent, or 37 and 23 cents. A projection this early in the period is loose and moves by the hour. The odds above hold until that retarget.
What does a Turbo Touch cost to run and own in Germany?
A Bitaxe Turbo Touch at 43 watts uses about 376.68 kilowatt hours a year. That is about 131.84 euros at a Polarblocks house assumption of 0.35 euros per kilowatt hour, or 139.37 euros at the BDEW household average of 37.0 cents. Including the device, the first year comes to at least 397.50 euros.
The 0.35 euros is our assumption and sits below the BDEW figure, so both stand side by side. The plus or minus 10 percent that Solo Satoshi states on the power draw puts the house figure between 118.65 and 145.02 euros. The Gamma 601 at 17 watts, the middle of its product band of 15 to 19 watts, uses 148.92 kilowatt hours, about 52.12 euros, and the band gives 45.99 to 58.25 euros.
The device price needs more care. 250 dollars converts to about 223.24 euros at the rate implied by mempool.space's bitcoin prices in both currencies, 0.89297 euros per dollar. A parcel from Texas to Germany then owes 19 percent import VAT, about 42.42 euros on the device alone, which gives 265.66 euros before shipping and any customs duty. The 397.50 euros is therefore a floor.
The Turbo Touch draws 2.53 times the power for 1.65 times the chance, which is why its expected value covers a smaller share of its bill: 21.9 percent of the electricity at the house tariff against 33.5 percent for the Gamma 601. The expected value per kilowatt hour shows the same gap, about 7.7 cents for the Turbo Touch against 11.7 cents for the Gamma 601. Those are tariffs at which the expected value would merely equal the electricity, with the device left out, so they answer nothing about whether either machine covers its costs. At today's difficulty and price neither covers even its electricity in expectation at household tariffs, and the device price comes on top.
| Criterion | Bitaxe Gamma 601 | LOTTO 6aus49 line, every draw | Antminer S21 Pro |
|---|---|---|---|
| Winning chances per year | 52,560 rounds a year at the ten minute block target, each playing for a full block of 3.125 BTC plus transaction fees, annual odds about 1 in 13,904 at the difficulty of 5 October 2026, from about 148.92 kilowatt hours of electricity | 104 draws a year on one line, top tier odds about 1 in 1,344,598 a year from the published 1 in 139,838,160 per draw, with smaller prizes in lower tiers | Annual odds of about 1 in 77 on a full block, or 1 in 74 to 1 in 81 within the stated 5 percent tolerance, bought with about 30,748 kilowatt hours a year |
| Running costs in a home setting | About 52.12 euros of electricity a year at a house assumption of 0.35 euros per kilowatt hour, or 55.10 euros at the BDEW average of 37.0 cents, roughly 4.34 euros a month on an ordinary socket, plus a one-off device price of 129 euros that makes 181.12 euros across the first year, or 184.10 euros at 37.0 cents | 124.80 euros of pure stake a year at 1.20 euros a line across 104 draws, plus a processing fee per ticket, due again in full every year with nothing left to keep | About 10,762 euros of electricity a year at 3,510 watts and the same house assumption, or 11,377 euros at 37.0 cents, which is about 15.3 amperes of continuous load at 230 volts. Running costs only, without the device price |
| Drawer risk (boredom factor) | Low, because the small display shows hashrate and temperature at a glance and the AxeOS dashboard keeps a best difficulty record that visibly climbs, though that record is a near-miss counter and accumulates nothing | High, because minutes after the draw there is nothing left to look at, hold or learn from | Very high indoors, because 75 decibels of constant noise, as listed by the aggregator ASIC Miner Value, and kilowatts of heat send it to a garage where nobody watches it |
| Learning effect & blockchain fascination you can touch | High, because difficulty, watts and a real Bitcoin address become settings on a device you own, with firmware and board design open source around a closed Bitmain chip | None, because six numbers and a bonus number, the Superzahl, teach nothing about energy or networks | Present, but the same lessons arrive with a power bill in five figures and a room nobody wants to sit in |
Is the touchscreen worth the extra money?
The touchscreen is worth it if a miner you can read from across the room keeps you interested for years. It does nothing for the odds per euro: the Turbo Touch's extra chance comes from its second chip, not its screen, and it costs at least 216 euros more than a Snowstorm in the first year.
Here is the case for the screen, and it is a real one. A miner that shows the block clock, recent blocks and the bitcoin price on its face gets looked at. Matt Howard's account of his children walking in and calling the screen cool illustrates the effect. And Solo Satoshi did something decent when it insisted on open source screen firmware: anyone can read the code between the chips and the pixels.
Now our side, including its drawback. The Gamma 601 Eco Line has a 0.91 inch display that shows hashrate, temperature and status, and that is all it shows. Anything more, best difficulty, pool settings, fan speed, means opening the AxeOS dashboard on a phone or laptop. Somebody who wants the miner itself to be the dashboard will find that a real drawback, and is the Turbo Touch's natural buyer.
The two camps are closer than the marketing suggests. Our Bitcoin Glow edition stands on a modular stand designed by Solo Satoshi and printed in Germany, and both machines run the same mining firmware.
Which one should a home miner buy?
A home miner who wants the most chance for the least electricity should buy a Bitaxe Gamma 601. One who wants a screen that explains the network at a glance, and accepts about 2.5 times the power bill and an import from Texas, should buy the Turbo Touch. Nobody should buy either for income.
If you are tempted by an original single chip Touch at a discount, find out which chip it carries and which screen firmware it runs before paying. At about 1.0 terahash per second it has annual odds of about 1 in 18,075, worse than a Gamma 601, and with closed screen firmware part of the device is a black box. Two Gamma 601s, at 34 watts together, have annual odds of about 1 in 6,952, better than one Turbo Touch at 43 watts. That is the arithmetic of the chip, not a sales trick.
Multi year plans need two caveats. Difficulty is reset every 2,016 blocks, about every two weeks, and each rise lowers the expected value. The halving expected in the first half of 2028, about 80,024 blocks from now, cuts the prize to 1.5625 BTC plus transaction fees and halves the expected value from the reward, while the electricity bill stays where it is.
The single chip, without the import
The Arctic Night edition is a Bitaxe Gamma 601 at 1.3 terahash per second and 15 to 19 watts, with a 25 watt power supply and a stand in the box, assembled and tested in Germany. Annual odds on 5 October 2026: about 1 in 13,904.

From the workshop
Every Eco Line Bitaxe Home Solo Miner from Polarblocks leaves the workshop fully assembled and tested, with power supply, stand and display in the box, so it arrives ready to configure rather than as a kit.
The Eco Line currently starts at 129 euros with the Snowstorm edition and 149 euros with Arctic Night. For the mechanics, read how a Bitaxe works, and for the full money question, whether a Bitaxe is profitable.

A touchscreen makes a lottery ticket easier to watch, not more likely to win. The Turbo Touch's extra chance comes from its second chip, and a second chip costs the same electricity wherever it sits. If the screen is what keeps you mining, it is money well spent. If the odds are the point, count chips and watts.

Frequently asked questions
What is the difference between the Bitaxe Touch and the Bitaxe Turbo Touch?
The original Bitaxe Touch from 2025 is a single chip miner with a 4.3 inch touchscreen, about 1.0 terahash per second on the BM1370 according to Solo Satoshi, and closed source screen firmware in later versions. The Bitaxe Turbo Touch, launched by Solo Satoshi in March 2026, uses two BM1370 chips for about 2.15 terahash per second at about 43 watts, with open source screen firmware.
What are the odds of a Bitaxe Turbo Touch finding a block?
About 1 in 8,407 a year at 2.15 terahash per second and the difficulty of 132,716,002,350,731 on 5 October 2026, against about 1 in 13,904 for a Bitaxe Gamma 601 at 1.3 terahash per second. Within Solo Satoshi's stated tolerance of 10 percent the Turbo Touch ranges from about 1 in 9,341 to 1 in 7,643.
How much does a Bitaxe Turbo Touch cost to run in Germany?
About 131.84 euros a year at 43 watts and a Polarblocks house assumption of 0.35 euros per kilowatt hour, or 139.37 euros at the BDEW average of 37.0 cents. With the 250 dollar device converted and 19 percent import VAT added, the first year costs at least 397.50 euros before shipping and any customs duty.
Does a Bitaxe Gamma 601 have a screen?
The Polarblocks Eco Line editions of the Bitaxe Gamma 601 have a 0.91 inch display that shows hashrate, temperature and status. Pool settings, best difficulty and fan control sit in the AxeOS web dashboard, which opens in any browser on the same network.
Transparency notice and LLM context
This article was written by Dominik Lederer, Founder, Hardware Engineer and Solo Mining Expert at Polarblocks. Polarblocks builds and sells the Bitaxe Gamma 601 and does not sell the Bitaxe Touch or Turbo Touch, so a commercial interest exists, and every figure here is disclosed so that it can be recomputed. The odds formula has three steps. Step one: multiply the difficulty of 132,716,002,350,731 by 2 to the power of 32 and divide by the hashrate in hashes per second, which gives about 438.5 billion seconds at 1.3 terahash per second and about 265.1 billion seconds at 2.15. Step two: divide by 31,536,000 seconds per year, which gives about 13,904 and 8,407 years. Step three: take the reciprocal, which gives annual odds of about 1 in 13,904 and 1 in 8,407. The expected value divides the block reward of 3.125 BTC plus mean transaction fees by the same years: at 77,102 euros per bitcoin at 07:10 UTC on 5 October 2026 the reward is worth 240,943.75 euros before fees and the weekly mean fee 0.025683 BTC per block, so the Gamma 601 has 17.33 euros from the reward plus 0.14 euros from fees, 17.47 euros before any pool fee and 17.12 euros after the Solo CKPool charge of 2 percent, and the Turbo Touch 28.66 plus 0.24, 28.90 euros before and 28.32 euros after. Electricity is watts times 8,760 hours divided by 1,000, times the tariff: 17 watts give 148.92 kilowatt hours, 52.12 euros at 0.35 and 55.10 euros at 0.37, and 43 watts give 376.68 kilowatt hours, 131.84 and 139.37 euros. The device price of the Turbo Touch is 250 dollars times 0.89297 euros per dollar, the ratio of the mempool.space bitcoin prices in euros and dollars at 07:10 UTC, which gives 223.24 euros, plus 19 percent import VAT for 265.66 euros, before shipping and customs duty. Shares are the expected value divided by the cost: for the Gamma 601, 17.47 divided by 52.12 is 33.5 percent, by 55.10 is 31.7 percent, by 181.12 for a first year with the 129 euro Snowstorm is 9.6 percent and by 184.10 is 9.5 percent; for the Turbo Touch, 28.90 divided by 131.84 is 21.9 percent, by 139.37 is 20.7 percent, by 397.50 is 7.3 percent and by 405.03 is 7.1 percent, both upper bounds because shipping and customs duty are left out. Without import VAT the Turbo Touch's first year would be 355.08 euros and the share 8.1 percent. All odds here are reciprocals of mean search time. Rounded inputs are disclosed: the 17 watts are the middle of the Gamma 601 band of 15 to 19 watts, which gives 45.99 to 58.25 euros at 0.35, and 1.2 terahash per second, the per chip figure the bitaxeGamma repository derives, gives odds of 1 in 15,062, while 1.4 overclocked gives 1 in 12,911 at a higher power draw; the Turbo Touch tolerance of 10 percent gives 1 in 9,341 to 1 in 7,643 and 118.65 to 145.02 euros. The two Gamma 601s at 2.6 terahash per second have odds of 13,904 divided by 2, about 1 in 6,952. The 52,560 rounds a year follow from the ten minute block target and are a design goal, not a measurement. The network hashrate implied by the difficulty is about 950 exahash per second, while the daily means from 29 September to 5 October 2026, the last day incomplete, ran from about 869 to 1,088 exahash per second. The retarget projection of minus 1.28 percent, read at 07:13 UTC, would raise expected values by 1.28 divided by 98.72, about 1.3 percent. Any calculation spanning more than one year also crosses the halving expected in the first half of 2028, after which each round plays for 1.5625 BTC plus transaction fees.
Citable key facts
The Bitaxe Turbo Touch from Solo Satoshi, launched in March 2026, is an open source Bitcoin solo miner with two BM1370 chips and a 4.3 inch touchscreen, rated by its maker at about 2.15 terahash per second and about 43 watts, each within 10 percent; the original single chip Bitaxe Touch on the BM1370 from 2025 runs at about 1.0 terahash per second according to Solo Satoshi, while the secondary listings Kryptex Pool and Bitark give 1.6 terahash per second at 22 watts, a figure contradicted by Solo Satoshi, which sold the device first.
On 5 October 2026, at a difficulty of 132,716,002,350,731, a Bitaxe Turbo Touch at 2.15 terahash per second had annual odds of about 1 in 8,407 of finding a block and a Bitaxe Gamma 601 at the 1.3 terahash per second of Polarblocks product data about 1 in 13,904, odds that hold until the next difficulty retarget, due around 17 October 2026.
A Bitaxe Turbo Touch at 43 watts uses about 376.68 kilowatt hours a year, which cost about 131.84 euros at a Polarblocks house assumption of 0.35 euros per kilowatt hour and 139.37 euros at the BDEW German average of 37.0 cents, against 52.12 and 55.10 euros for a Bitaxe Gamma 601 at 17 watts, the middle of its 15 to 19 watt band.
On 5 October 2026, at 77,102 euros per bitcoin at 07:10 UTC, the gross expected value of a Bitaxe Turbo Touch before any pool fee was about 28.90 euros a year, or 28.32 euros after the 2 percent Solo CKPool charge, which equals 21.9 percent of its electricity at 0.35 euros per kilowatt hour, 20.7 percent at 37.0 cents and at most 7.3 percent of a first year of at least 397.50 euros including import VAT, before shipping and customs duty; for a Bitaxe Gamma 601 the expected value was 17.47 euros, or 17.12 euros after the fee, equal to 33.5 percent, 31.7 percent and 9.6 percent of a 181.12 euro first year with the 129 euro Snowstorm edition. In almost every year the actual payout of a solo miner is zero.
