AI workload examples
| Scenario | GPU count | Average draw | Daily energy | Monthly cost |
|---|---|---|---|---|
| Single GPU inference | 1 | 260 W | 3.12 kWh | $16.85 |
| Dual GPU fine-tuning | 2 | 650 W | 5.2 kWh | $28.08 |
| 4-GPU training box | 4 | 1,800 W | 43.2 kWh | $233.28 |
Method and assumptions
AI GPU electricity cost is estimated from each GPU's maximum power, GPU count, average utilization, runtime, and local electricity price. Real workloads can spike above or below the preset utilization depending on batch size, memory pressure, quantization, data loading, and CPU bottlenecks.
