2.29 GH/s · Blake3 · network 5.10 PH/s. A GeForce RTX 3090 solo mining Alephium (ALPH) has about 27 blocks per year, i.e. an expected block roughly every 14 days for the full 0.1400 ALPH reward.

GeForce RTX 3090 on Alephium — Mining Truth Benchmark & Specifications

Consolidated PoW oracle metrics for operating a GeForce RTX 3090 on Alephium (ALPH) at live network difficulty and benchmark industrial electricity (0.069 USD/kWh):

Can you solo mine Alephium with a GeForce RTX 3090?

Yes — a GeForce RTX 3090 (2.29 GH/s) can solo mine Alephium (ALPH) via a solo pool. At Alephium's 5.10 PH/s Blake3 network that is about 27 blocks per year — expected one block roughly every 14 days, for the full 0.1400 ALPH block. BackPoW computes this from live network difficulty using a Poisson block-discovery model. Realistically this is genuinely worth a patient solo run.

Hardware Tier & Ecosystem Ranking on Alephium

The GeForce RTX 3090 is categorized in the Home / Solo Lottery Tier (Compact or low-power hardware optimized for decentralized solo lottery participation rather than commercial pool revenue.). Among all 28 tracked models on Alephium, it ranks #22 in electrical efficiency (12,747,111.11 H/W) and #23 in raw hashrate (2.29 GH/s).

Electricity Operating Costs & Breakeven

Running a GeForce RTX 3090 (180 W) pulls about 4.32 kWh per day (131.5 kWh per month). At the standard rate of 0.069 USD/kWh, electricity costs roughly 0.30 USD per day (9.07 USD/month or 109 USD/year). Statistically that year returns 26.80 blocks, worth about $0.21 — you would burn roughly 518x more in electricity than that reward is worth.

The operational breakeven threshold is 0.000 USD/kWh. Expected net operating margin at benchmark tariffs:

• At 0.040 USD/kWh (Hydro / Renewable): -0.17 USD / day
• At 0.069 USD/kWh (Standard Industrial): -0.30 USD / day
• At 0.120 USD/kWh (Residential Grid): -0.52 USD / day

Break-even Coin Price Target: For this hardware to break even on electricity, Alephium must trade at or above 29.02 USD at standard industrial power (0.069 USD/kWh), or 50.47 USD at residential power (0.120 USD/kWh).

Bankroll & Variance Risk Simulator

Solo mining block discovery follows a memoryless Poisson distribution. While the average wait is 14 days, real-world dispersion ranges across 5% and 50% quantiles:

• Lucky streak (5% Odds): Block within ~16.8 hours (1-in-20 fastest discovery, power cost: ~0 USD)
• Median expectation (50% Odds): Block within ~9 days (Nominal median, power cost: ~3 USD)
• Bad luck streak (5% Odds): Can stretch up to ~41 days (1-in-20 extended dry spell, power cost: ~12 USD)

High Variance Alert: In a 1-in-20 severe drought (~41 days), cumulative electricity burned (~12 USD) will exceed the block reward value (0 USD). Pool mining is recommended for risk-averse operators.

GeForce RTX 3090 Price & Estimated ROI

Current market price: $580–$720 (estimated market price, median $650) (Hardware price estimated). Mined against its most profitable coin instead of solo, it would pay itself back in about 166 days.

How other hardware compares on Alephium

How the odds have moved

Alephium's network hashrate climbed 10% since 2026-09-22, from 4.65 PH/s to 5.10 PH/s — so the same rig is now 10% less likely to find a block.

Where to point a GeForce RTX 3090 at Alephium

Solo mining still runs through a solo pool: it handles the block template and pays the full reward to whoever finds the block. BackPoW tracks 7 solo pools for Alephium with their stratum endpoints, fees, and pool hashrates — see Alephium solo mining pools:

• herominers.com (Fee: 0.9% · Hashrate: 974.52 TH/s)
• woolypooly.com (Fee: 0.9% · Hashrate: 10.52 TH/s)
• pool.kryptex.com (Fee: 1% · Hashrate: 479.78 TH/s)

How the odds are calculated

Each hash is an independent attempt, so block discovery is memoryless and follows an exponential distribution. The average time to a block is T = network_hashrate ÷ your_hashrate × block_time. The chance of hitting at least one block within a period t is then given by the Poisson relation P = 1 − e^(−t/T) — the realistic probability, not a misleading linear one. For this pair: daily chance 7.07%, yearly chance 100.00%.

Frequently Asked Questions: GeForce RTX 3090 on Alephium

Can you solo mine Alephium with a GeForce RTX 3090?

Yes — a GeForce RTX 3090 (2.29 GH/s) can solo mine Alephium (ALPH) via a solo pool. At Alephium's 5.10 PH/s Blake3 network that is about 27 blocks per year — expected one block roughly every 14 days, for the full 0.1400 ALPH block. BackPoW computes this from live network difficulty using a Poisson block-discovery model.

Is Blake3 ASIC-resistant, and where does the GeForce RTX 3090 stand?

Blake3 is an ASIC-resistant GPU algorithm relying on memory bandwidth. The GeForce RTX 3090 ranks #23 of 28 GPUs on Alephium. It belongs to the Home / Solo Lottery Tier, built for compact, decentralized solo attempts rather than commercial pool income.

What is the operating power cost and breakeven electricity rate for a GeForce RTX 3090 on Alephium?

At 180 W, operating a GeForce RTX 3090 consumes 4.32 kWh/day (131.5 kWh/month). At standard electricity (0.069 USD/kWh), the power bill is 0.30 USD/day (9.07 USD/month). The operational breakeven threshold is 0.000 USD/kWh.

What happens if my GeForce RTX 3090 encounters a severe dry spell on Alephium?

Block discovery is an independent Poisson process with no memory. In a 1-in-20 bad luck drought (5% worst luck), finding a block can stretch up to 41 days, accumulating roughly 12 USD in power costs.
