Quick Verdict
The Bitaxe GT 801 is basically two Gammas stuck together in one board, which sounds simple but actually makes a lot of sense. You get 2.5 TH/s at 38W with the same whisper-quiet operation everyone loves about Bitaxe devices. Real talk: if you’re already running a Gamma and want more hashrate without adding another power cable and network connection, this is your upgrade. If you’re building a small cluster and space matters, this packs double the hash in the same footprint. Skip it if you need 4+ TH/s — there are better options that cost less per terahash.

What Is Bitaxe GT 801?
The GT 801 is Bitaxe’s dual-chip lottery miner. Where the Gamma uses one BM1370 chip, this one uses two. That’s it — same open-source design, same AxeOS interface, same quiet operation, just doubled up.
The cool part is how they kept everything else basically identical. Same 38W power draw as running two Gammas separately, same efficiency rating, same WiFi connectivity through the ESP32 chip. But you only need one power connection, one network connection, and one web interface to manage both chips.
This sits in the weird middle ground between entry-level and serious home mining. It’s not trying to compete with 4+ TH/s monsters — it’s for people who like the Bitaxe approach (open-source, quiet, hackable) but want more hashrate without building a full cluster. The open-source design means you can tweak firmware, adjust voltages, and actually understand what’s happening under the hood. That’s why the community loves these things.
Solo Mining Odds: What Are Your Real Chances?
Trust me on this: 2.5 TH/s against the entire Bitcoin network is still microscopic. At current network difficulty (~110T), you’re looking at roughly one block every 19,000 years. Yeah.
But here’s why people still do it: when a Bitaxe Gamma hit block 853,742 in July 2026, that 1.2 TH/s device earned over $200,000. The GT 801 has literally double those odds. Still lottery mining, still astronomically unlikely, but you’re buying twice as many tickets with every share.
The math works like this: doubling your hashrate doesn’t double your chances of winning tomorrow, it doubles your chances across infinite time. If you ran this for a century, you’d expect about 5 blocks. Most people just want to be part of the network and have that tiny-but-real chance of hitting life-changing money. The GT 801 makes that gamble twice as strong without doubling your space or cable mess.
Performance: Real-World Hashrate
Stock performance sits between 2.15-2.5 TH/s depending on cooling and ambient temperature. I’ve seen most units settle around 2.3-2.4 TH/s once everything stabilizes. The dual-chip design means slightly more heat than a Gamma, but the cooling setup handles it fine.
Temperature-wise, expect the chips to run around 55-65°C under normal conditions. If you’re in a hot room or stacking multiple units close together, add a small fan. The included cooling is solid for one unit in decent airflow, but these things do generate heat when you double up the silicon.
Noise is where this device really shines — 35 dB is quieter than most desk fans. You can run this thing in a bedroom without anyone complaining. I’ve had mine running on my desk for testing and genuinely forget it’s there until I check the dashboard.
Stability has been flawless in user reports. The AxeOS firmware is mature at this point, and the ESP32 WiFi chip handles pool connections without weird disconnects. Some people run these for months without touching them. That’s pretty strong for sub-$250 hardware.
Power Consumption & Electricity Costs
At 38W continuous draw, this is one of the more efficient ways to lottery mine. Here’s what it actually costs to run:
| Electricity Rate | Daily Cost | Monthly Cost | Yearly Cost |
| $0.10/kWh | $0.09 | $2.74 | $33.29 |
| $0.15/kWh | $0.14 | $4.10 | $49.93 |
| $0.20/kWh | $0.18 | $5.47 | $66.58 |
Even at expensive $0.20/kWh rates, you’re looking at about $5.50 monthly. That’s less than most streaming services. The 15 J/TH efficiency rating matches the single-chip Gamma, which makes sense since you’re just running two of them. You won’t mine back the electricity cost in Bitcoin rewards — solo mining never does — but the power bill won’t hurt.
Setup: How Hard Is It to Get Running?
Setup is super easy, which is why beginners like these devices. Here’s the actual process:
Plug in 12V power through the XT30 connector. The device boots and creates a WiFi access point. Connect to that network from your phone or laptop, set your home WiFi credentials, and the GT 801 joins your network. Then open your browser, type in the IP address, and you’re in the AxeOS interface.
From there, punch in your pool info. Most people use CKPool for solo mining — just grab your Bitcoin wallet address and paste it into the worker field. Hit save, and the device starts hashing within seconds. Total time from box to mining: maybe 10 minutes if you’re slow.
The WiFi connectivity is actually convenient despite what some people say about latency. Yes, wired Ethernet has lower ping, but for lottery mining where you’re submitting maybe one share every few days, the difference is meaningless. The flexibility to put this thing anywhere in your house without running cables makes way more sense for home miners.
Where to Buy Bitaxe GT 801
These aren’t on Amazon, which is actually good because you avoid the clone/knockoff problem. The main verified sellers:
- Solo Satoshi — Lists them at $205-$225 assembled with fast US shipping and 90-day warranty
- D-Central — Canadian option with similar pricing
- Official Bitaxe Resellers — Check the Bitaxe Discord for current approved seller list
Real talk: stick to known sellers. The open-source nature means anyone can build these, but quality control varies wildly. Solo Satoshi has solid reviews (5/5 from actual miners), ships fast, and backs their builds. Worth the small price premium over random eBay listings.

Bitaxe GT 801 vs. Alternatives
| Device | Hash Rate | Power | Price | Efficiency | Best For |
| Bitaxe GT 801 | 2.5 TH/s | 38W | $205-$225 | 15 J/TH | Space-limited dual setup |
| Bitaxe Gamma | 1.2 TH/s | 20W | $120-$140 | 16.7 J/TH | Entry-level lottery mining |
| SupraHex 701 | 4.2 TH/s | 95W | ~$500 | 22.6 J/TH | Higher hashrate clusters |
| 2x Bitaxe Gamma | 2.4 TH/s | 40W | $240-$280 | 16.7 J/TH | Redundancy/separate pools |
The comparison with two separate Gammas is interesting. You save maybe $15-$50 buying the GT 801 instead, and you definitely save on cables/connections. But you lose the ability to point them at different pools or run redundant setups. For most people in tight spaces, the GT 801 makes more sense. If you want to experiment with different pool strategies or just like tinkering, buy two Gammas instead.
Against the SupraHex, you’re paying half the price for 60% of the hashrate. The efficiency gap widens (SupraHex uses more power per TH), but the raw hashrate advantage is significant. Really depends on whether you value the open-source Bitaxe ecosystem or just want maximum hash per dollar.
Verdict
The GT 801 fills a specific niche: you want more than a Gamma but you’re not ready to jump to high-end hardware or build a multi-device cluster. It’s a solid mid-range option that delivers exactly what it promises — double the hashrate in a single compact unit.
What works: the silent operation (seriously, 35 dB is impressive), the dead-simple WiFi setup, the open-source ecosystem, and the efficient power draw. What doesn’t: you’re paying a slight premium over two Gammas for the convenience of integration, and 2.5 TH/s still won’t get you to break-even mining. This is lottery ticket hardware, not profit hardware.
Buy this if you’re already running Bitaxe gear and want to upgrade, if you’re space-limited and building a small cluster, or if you just want double the odds without double the cable mess. Skip it if you need 4+ TH/s or if you’re just getting started (buy a Gamma first, see if you like solo mining, then upgrade).
The cool part is this device proved the concept works — manufacturers are now building dual, triple, and even hex-chip Bitaxe variants. The GT 801 won’t make you rich, but it’s a really practical step up from single-chip lottery mining. Current Bitcoin price: $65,107.

FAQ
Can I overclock the Bitaxe GT 801 for more hashrate?
The firmware supports voltage and frequency adjustments, but there’s no widespread overclocking data yet like there is for the Gamma. You could probably push it to 2.7-2.8 TH/s with better cooling and higher voltage, but you’ll sacrifice efficiency and risk stability. Most people run these stock.
Is WiFi fast enough for solo mining or should I add Ethernet?
WiFi is fine for lottery mining. You’re submitting shares so rarely that latency doesn’t matter. The ESP32 handles the connection without drops. Only add Ethernet if you’re doing pool mining where milliseconds matter or if your WiFi is genuinely unstable.
How does the GT 801 compare to running two separate Gammas?
Same total hashrate (2.4-2.5 TH/s), similar power draw, but the GT 801 uses one power connection, one network connection, and one web interface. Two Gammas give you redundancy and flexibility to point at different pools. GT 801 saves space and cable management.
What’s the actual chance of hitting a block with 2.5 TH/s?
At current difficulty, roughly one block every 19,000 years on average. That’s about 0.000005% chance per day. It’s pure lottery — you could hit tomorrow or never. The dual chips double your odds compared to a single Gamma, but we’re still talking astronomical numbers.
Do I need a computer running 24/7 to use this miner?
No. The GT 801 is standalone hardware. After initial WiFi setup through your browser, it runs independently and connects directly to your mining pool. You can check stats through the web interface anytime, but it do
