215.62 MH/s · Etchash · network 172.01 TH/s. A GeForce RTX 5090 solo mining EthereumClassic (ETC) has about 3 blocks per year, i.e. an expected block roughly every 125 days for the full 1.5900 ETC (≈ 13 USD) reward.

GeForce RTX 5090 on EthereumClassic — Mining Truth Benchmark & Specifications

Consolidated PoW oracle metrics for operating a GeForce RTX 5090 on EthereumClassic (ETC) at live network difficulty and benchmark industrial electricity (0.069 USD/kWh):

Can you solo mine EthereumClassic with a GeForce RTX 5090?

Yes — a GeForce RTX 5090 (215.62 MH/s) can solo mine EthereumClassic (ETC) via a solo pool. At EthereumClassic's 172.01 TH/s Etchash network that is about 3 blocks per year — expected one block roughly every 125 days, for the full 1.5900 ETC (≈ 13 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 EthereumClassic

The GeForce RTX 5090 is categorized in the Commercial / High-Yield Tier (Top quartile hashrate on this network, highly competitive for regular pool revenue or realistic solo mining.). Among all 14 tracked models on EthereumClassic, it ranks #2 in electrical efficiency (539,058.75 H/W) and #1 in raw hashrate (215.62 MH/s).

Electricity Operating Costs & Breakeven

Running a GeForce RTX 5090 (400 W) pulls about 9.60 kWh per day (292.2 kWh per month). At the standard rate of 0.069 USD/kWh, electricity costs roughly 0.66 USD per day (20.16 USD/month or 242 USD/year). Statistically that year returns 2.92 blocks, worth about $36.80 — you would burn roughly 7x more in electricity than that reward is worth.

The operational breakeven threshold is 0.010 USD/kWh. Expected net operating margin at benchmark tariffs:

• At 0.040 USD/kWh (Hydro / Renewable): -0.28 USD / day
• At 0.069 USD/kWh (Standard Industrial): -0.56 USD / day
• At 0.120 USD/kWh (Residential Grid): -1.05 USD / day

Break-even Coin Price Target: For this hardware to break even on electricity, EthereumClassic must trade at or above 52.13 USD at standard industrial power (0.069 USD/kWh), or 90.67 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 125 days, real-world dispersion ranges across 5% and 50% quantiles:

• Lucky streak (5% Odds): Block within ~6 days (1-in-20 fastest discovery, power cost: ~4 USD)
• Median expectation (50% Odds): Block within ~87 days (Nominal median, power cost: ~57 USD)
• Bad luck streak (5% Odds): Can stretch up to ~1.03 yr (1-in-20 extended dry spell, power cost: ~248 USD)

High Variance Alert: In a 1-in-20 severe drought (~1.03 yr), cumulative electricity burned (~248 USD) will exceed the block reward value (13 USD). Pool mining is recommended for risk-averse operators.

GeForce RTX 5090 Price & Estimated ROI

Current market price: $5,816–$7,034 (estimated market price, median $6,503) (Hardware price estimated). Mined against its most profitable coin instead of solo, it would pay itself back in about 508 days.

How other hardware compares on EthereumClassic

How the odds have moved

EthereumClassic's network hashrate climbed 18% since 2026-09-22, from 145.48 TH/s to 172.01 TH/s — so the same rig is now 18% less likely to find a block.

Where to point a GeForce RTX 5090 at EthereumClassic

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

• herominers.com (Fee: 0.9% · Hashrate: 223.07 GH/s)
• woolypooly.com (Fee: 0.9% · Hashrate: 24.27 GH/s)
• k1pool.com (Fee: 1% · Hashrate: 303.31 GH/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 0.7959%, yearly chance 94.60%.

Frequently Asked Questions: GeForce RTX 5090 on EthereumClassic

Can you solo mine EthereumClassic with a GeForce RTX 5090?

Yes — a GeForce RTX 5090 (215.62 MH/s) can solo mine EthereumClassic (ETC) via a solo pool. At EthereumClassic's 172.01 TH/s Etchash network that is about 3 blocks per year — expected one block roughly every 125 days, for the full 1.5900 ETC (≈ 13 USD) block. BackPoW computes this from live network difficulty using a Poisson block-discovery model.

Is Etchash ASIC-resistant, and where does the GeForce RTX 5090 stand?

Etchash is an ASIC-resistant GPU algorithm relying on memory bandwidth. The GeForce RTX 5090 ranks #1 of 14 GPUs on EthereumClassic. It sits in the Commercial / High-Yield Tier (top quartile), making it highly competitive for steady pool income and realistic solo mining.

What is the operating power cost and breakeven electricity rate for a GeForce RTX 5090 on EthereumClassic?

At 400 W, operating a GeForce RTX 5090 consumes 9.60 kWh/day (292.2 kWh/month). At standard electricity (0.069 USD/kWh), the power bill is 0.66 USD/day (20.16 USD/month). The operational breakeven threshold is 0.010 USD/kWh.

What happens if my GeForce RTX 5090 encounters a severe dry spell on EthereumClassic?

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 1.03 yr, accumulating roughly 248 USD in power costs.
