Introduction
The cryptocurrency mining landscape experienced a significant surge following the global Bitcoin ransomware outbreak in recent years. This event revitalized interest in virtual currencies, propelling Ethereum, Litecoin, and other altcoins to unprecedented values. The resulting mining frenzy caused GPU shortages and price hikes as miners scrambled to build or upgrade their rigs.
This guide provides essential information for Ethereum miners, including:
- GPU performance comparisons
- Power consumption metrics
- Hardware configuration recommendations
- Mining profitability factors
Ethereum Fundamentals
Total Supply and Mining Timeline:
- Initial supply: 72 million ETH
- Annual growth: ~15 million
- Transitioned to Proof-of-Stake (PoS) algorithm in 2022 (mining no longer possible)
- Block reward: 5 ETH per block
- Daily production: ~40,000 ETH (pre-PoS)
GPU Hash Rate Comparison Table
| GPU Model | Hash Rate (MH/s) | Power Consumption (W) |
|---|---|---|
| NVIDIA RTX 3090 | 120-130 | 300-350 |
| AMD RX 6900 XT | 60-65 | 250-300 |
| NVIDIA GTX 1080 Ti | 30-35 | 180-220 |
| AMD RX 580 | 25-30 | 150-180 |
Note: Actual performance may vary based on cooling, overclocking, and mining software optimization.
Optimal Mining Hardware Configuration
For those building dedicated Ethereum mining rigs:
GPU Selection Priority:
- Hash rate per watt efficiency
- Availability and pricing
- Cooling requirements
Supporting Components:
- High-efficiency power supply (80+ Platinum recommended)
- Adequate cooling solutions
- Stable motherboard with multiple PCIe slots
Operating System:
- Lightweight Linux distributions preferred
- Specialized mining OS options available
👉 Check current mining profitability
Power Consumption Considerations
- Calculate total system wattage (GPUs + supporting components)
- Factor in electricity costs for profitability analysis
- Consider undervolting/underclocking for efficiency
Example 6-GPU Rig Power Draw:
- 6 x RX 580: 900-1080W
- System components: 150W
- Total: 1050-1230W
