How does the optimal GPU mix algorithm work?
The calculator uses efficiency-weighted scoring that adapts to your electricity cost. Cheap power favours raw hashrate; expensive power favours MH/s per watt.
The calculator uses an efficiency-weighted scoring algorithm that adapts to your electricity cost. It tries every possible combination of GPUs (up to 2 types) that fits within the rig's GPU budget.
| Energy Cost | Hashrate Weight | Efficiency Weight | Behaviour |
|---|---|---|---|
| £0.00 (free) | 100% | 0% | Pure hashrate — pack in the most powerful GPUs |
| £0.05 (solar) | 65% | 35% | Slight efficiency bias |
| £0.10+ (grid) | 30% | 70% | Strong efficiency bias — favour MH/s per watt |
For the Miner 1000 mining ETC:
- At £0.05/kWh → 1× RTX 5090 + 7× RTX 5080 (1000 MH/s, 1690W)
- At £0.26/kWh → 1× RTX 5090 + 7× RTX 5080 (1000 MH/s, 1690W)
ℹ️ Move the Energy Cost slider in the calculator and watch the "Optimal Mix" card change in real-time. The algorithm recalculates instantly.
