Frequently Asked Questions
Is the NVIDIA GeForce RTX 3080 Ti or NVIDIA GeForce RTX 4090 more profitable for Monero mining?
Based on hashrate-per-watt efficiency, the NVIDIA GeForce RTX 4090 is more efficient for Monero mining. However, actual profitability depends on your electricity cost, hardware acquisition price, and coin price — use the live calculator for exact numbers.
What is the power consumption difference between the NVIDIA GeForce RTX 3080 Ti and NVIDIA GeForce RTX 4090?
For Monero mining, the NVIDIA GeForce RTX 3080 Ti draws 290 W while the NVIDIA GeForce RTX 4090 draws 350 W. The NVIDIA GeForce RTX 3080 Ti uses 60 W less power, which at $0.07/kWh saves ~$37 per year in electricity.
Can both the NVIDIA GeForce RTX 3080 Ti and NVIDIA GeForce RTX 4090 mine the same coins?
Yes — both units can mine Monero (XMR) and Ravencoin (RVN) and Ethereum Classic (ETC) and Alephium (ALPH). You can switch between these coins with a simple pool configuration change.
Which unit has a better ROI?
ROI depends on hardware acquisition price, electricity cost, and coin price trajectory. The more efficient unit (better J/TH or hashrate per watt) will generally have a lower operating cost per coin mined, but the absolute ROI timeline is determined by the purchase price. Always model both units in the MiningReturns calculator with your specific electricity rate and current market prices.
