Introduction: The Ethereum Mining Landscape
The cryptocurrency mining boom has transformed the GPU market, with Ethereum (ETH) miners driving unprecedented demand for graphics cards. As the second-largest cryptocurrency after Bitcoin, ETH mining remains highly profitable when done correctly. This guide provides a comprehensive comparison of GPU hashrates and practical advice for selecting mining hardware.
Top Mining GPUs: Performance Breakdown
NVIDIA Cards
- GTX 1080 Ti: 35-40 MH/s
- GTX 1080: 25-30 MH/s
- GTX 1070: 25-28 MH/s
- GTX 1060 (6GB): 20-22 MH/s
AMD Cards (Superior Hashrate Performance)

Key Selection Criteria for Mining GPUs
Minimum 4GB VRAM Requirement
- Cards like GTX 1050 (2GB) are unusable for ETH mining
- 8GB models provide better future-proofing
Power Efficiency Ratio
- Calculate MH/s per watt (performance per energy cost)
- AMD cards typically offer better efficiency for mining
Availability and Market Pricing
- Monitor price trends during crypto market fluctuations
- Consider buying used cards during market downturns
Mining Rig Configuration Tips
Optimal Setup
- 6-card systems provide the best balance of cost and performance
Example configuration:
- 6x RX 570 (8GB) = ~150 MH/s total
- Expected ROI: 5-6 months at current difficulty
Thermal Management
- Maintain at least 2-inch spacing between cards
- Use open-air mining frames for best airflow
- Install additional case fans (120mm minimum)
Market Considerations
- Global GPU shortage continues affecting availability
- Secondary market prices fluctuate with crypto values
- ASIC resistance makes ETH particularly suitable for GPU mining

Frequently Asked Questions
Q: How much can I earn with a single GPU?
A: Solo mining isn't profitable. You'll need at least 6 GPUs (80+ MH/s) to see meaningful returns.
Q: Which brand is better for mining - NVIDIA or AMD?
A: AMD cards generally offer superior hashrates for Ethereum mining, though NVIDIA models may be more power-efficient.
Q: How often should I clean my mining rig?
A: Perform thorough cleaning every 3 months to prevent dust buildup affecting thermals.
Q: What's the ideal ambient temperature for mining?
A: Maintain below 25°C (77°F) for optimal card performance and longevity.
Q: Can I game on my mining GPU?
A: Possible but not recommended - continuous mining operation provides better ROI.
Conclusion
Selecting the right GPU involves balancing:
- Initial investment cost
- Ongoing power expenses
- Expected hashrate performance
- Equipment availability
The RX 500 series (570/580) currently offers the best combination of performance and value for Ethereum miners, though all quality GPUs remain in high demand. Always calculate your specific ROI based on current electricity costs and Ethereum network difficulty.
