GeForce RTX 3080 12GB on IronFish — Mining Truth Benchmark & Specifications

Consolidated PoW oracle metrics for operating a GeForce RTX 3080 12GB on IronFish (IRON) at live network difficulty and benchmark industrial electricity (0.069 USD/kWh):

Can you solo mine IronFish with a GeForce RTX 3080 12GB?

Yes — a GeForce RTX 3080 12GB (68.10 MH/s) can solo mine IronFish (IRON) via a solo pool. At IronFish's 221.67 GH/s FishHash network that is about 163 blocks per year — expected one block roughly every 2 days, for the full 17.2500 IRON (≈ 1 USD) 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 IronFish

The GeForce RTX 3080 12GB is categorized in the Mid-Range Workhorse Tier (Middle quartile hashrate offering solid pool mining throughput with moderate solo variance.). Among all 11 tracked models on IronFish, it ranks #8 in electrical efficiency (261,904.62 H/W) and #7 in raw hashrate (68.10 MH/s).

Electricity Operating Costs & Breakeven

Running a GeForce RTX 3080 12GB (260 W) pulls about 6.24 kWh per day (189.9 kWh per month). At the standard rate of 0.069 USD/kWh, electricity costs roughly 0.43 USD per day (13.11 USD/month or 157 USD/year). Statistically that year returns 163.13 blocks, worth about $208 — expected revenue covers the power bill about 1.3x over.

The operational breakeven threshold is 0.091 USD/kWh. Expected net operating margin at benchmark tariffs:

• At 0.040 USD/kWh (Hydro / Renewable): +0.32 USD / day
• At 0.069 USD/kWh (Standard Industrial): +0.14 USD / day
• At 0.120 USD/kWh (Residential Grid): -0.18 USD / day

Break-even Coin Price Target: For this hardware to break even on electricity, IronFish must trade at or above 0.0559 USD at standard industrial power (0.069 USD/kWh), or 0.0972 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 2 days, real-world dispersion ranges across 5% and 50% quantiles:

• Lucky streak (5% Odds): Block within ~2.8 hours (1-in-20 fastest discovery, power cost: ~0 USD)
• Median expectation (50% Odds): Block within ~2 days (Nominal median, power cost: ~1 USD)
• Bad luck streak (5% Odds): Can stretch up to ~7 days (1-in-20 extended dry spell, power cost: ~3 USD)

High Variance Alert: In a 1-in-20 severe drought (~7 days), cumulative electricity burned (~3 USD) will exceed the block reward value (1 USD). Pool mining is recommended for risk-averse operators.

GeForce RTX 3080 12GB Price & Estimated ROI

Current market price: $360–$440 (estimated market price, median $400) (Hardware price estimated). Mined against its most profitable coin instead of solo, it would pay itself back in about 160 days.

How other hardware compares on IronFish

How the odds have moved

IronFish's network hashrate fell 27% since 2026-09-18, from 301.99 GH/s to 221.67 GH/s — so the same rig is now 27% more likely to find a block.

Where to point a GeForce RTX 3080 12GB at IronFish

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 2 solo pools for IronFish with their stratum endpoints, fees, and pool hashrates — see IronFish solo mining pools:

• herominers.com (Fee: 0.9% · Hashrate: 127.57 GH/s)
• pool.kryptex.com (Fee: 1% · Hashrate: 59.80 GH/s)

How the odds are calculated

Because each hash succeeds independently, finding a block is a Poisson process — there is no 'due' block, only an average rate. The mean time between blocks is T = network_hashrate ÷ your_hashrate × block_time, and the realistic chance of at least one block over a period t is P = 1 − e^(−t/T). That is why a longer run raises your odds but never guarantees a block. For this pair: daily chance 36.02%, yearly chance 100.00%.

Frequently Asked Questions: GeForce RTX 3080 12GB on IronFish

Can you solo mine IronFish with a GeForce RTX 3080 12GB?

Yes — a GeForce RTX 3080 12GB (68.10 MH/s) can solo mine IronFish (IRON) via a solo pool. At IronFish's 221.67 GH/s FishHash network that is about 163 blocks per year — expected one block roughly every 2 days, for the full 17.2500 IRON (≈ 1 USD) block. BackPoW computes this from live network difficulty using a Poisson block-discovery model.

Is FishHash ASIC-resistant, and where does the GeForce RTX 3080 12GB stand?

FishHash is an ASIC-resistant GPU algorithm relying on memory bandwidth. The GeForce RTX 3080 12GB ranks #7 of 11 GPUs on IronFish. It operates in the Mid-Range Tier (middle quartile), offering solid pool mining throughput with moderate solo variance.

What is the operating power cost and breakeven electricity rate for a GeForce RTX 3080 12GB on IronFish?

At 260 W, operating a GeForce RTX 3080 12GB consumes 6.24 kWh/day (189.9 kWh/month). At standard electricity (0.069 USD/kWh), the power bill is 0.43 USD/day (13.11 USD/month). The operational breakeven threshold is 0.091 USD/kWh.

What happens if my GeForce RTX 3080 12GB encounters a severe dry spell on IronFish?

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 7 days, accumulating roughly 3 USD in power costs.
