Key Factors When Choosing a Mining GPU
1. Hashrate per Dollar
Calculate MH/s per dollar spent. The RTX 4070 delivers 0.09 MH/s per dollar vs RTX 4090's 0.07 MH/s per dollar.
2. Power Efficiency
Lower power = higher profit. The RTX 4070 uses 220W for 60 MH/s (0.27 MH/W) vs RTX 4090's 350W for 130 MH/s (0.37 MH/W).
3. Resale Value
NVIDIA cards hold value better. RTX 4070 retains ~60% value after 2 years vs AMD's ~50%.
4. Algorithm Flexibility
Some coins favor AMD (KAS), others NVIDIA. Consider mining multiple coins to maximize profit.
Mining Profitability Tips
- Electricity is king: If you pay above $0.10/kWh, GPU mining may not be profitable
- Use NiceHash: Auto-switches to most profitable coin
- Undervolt: Reduce power 20-30% with minimal hashrate loss
- Join a pool: Solo mining is not viable for most
- Track costs: Include hardware depreciation in profit calculations
