ETCHash comparison
NVIDIA GeForce RTX 4090 vs NVIDIA GeForce RTX 3080
The NVIDIA GeForce RTX 4090 is 49% more efficient per MH, which is what decides the break-even electricity price below. Both machines are modelled with identical assumptions and your own rate.
Side by side
| Measure | GeForce RTX 4090 | GeForce RTX 3080 |
|---|---|---|
| Hashrate | 260 MH/s | 102 MH/s |
| Power draw | 300 W | 230 W |
| Efficiency | 1.2 W/MH (better on this measure) | 2.3 W/MH |
| Revenue / day | $0.00 | $0.00 |
| Electricity / day | $0.432 | $0.3312 |
| Operating profit / day | -$0.432 | -$0.3312 (better on this measure) |
| Operating profit / month | -$12.96 | -$9.94 (better on this measure) |
| Break-even electricity | $0.00 (better on this measure) | $0.00 |
| Cooling | Air | Air |
| Home suitable | Yes | Yes |
Both machines assume a 1% pool fee at the current ETC price and network difficulty, running continuously. A highlighted figure is the better of the two on that measure — marked only where one genuinely is better, not on hashrate, power or revenue, which reflect the size of the machine rather than its quality. Highlighting is not a recommendation, and no manufacturer pays for placement here. Your rate is saved in this browser and applies across the site.
Our view
NVIDIA GeForce RTX 4090
260 MH/s · 300 W · 1.2 W/MH
The strongest consumer GPU for Ethereum Classic and genuinely usable at home, though the card costs far more than its mining return alone justifies. Its resale market is the real hedge.
NVIDIA GeForce RTX 3080
102 MH/s · 230 W · 2.3 W/MH
A capable second-hand option with good memory bandwidth for ETCHash. Check whether a card has already spent years mining before buying.
These are editorial judgements, not paid placements. Neither manufacturer has any influence over the ordering or the verdicts, and no purchase links on this page are affiliate links. Purchase price, warranty and availability are excluded because we do not yet publish a verified retailer feed — a comparison that invented them would be worse than one that omits them.
