Introduction
The recent surge in cryptocurrency interest has reignited the graphics card market, reminiscent of the 2013-2014 Litecoin mining boom. While not endorsing cryptocurrency activities, this analysis examines the practical performance metrics of popular GPUs for Ethereum mining. We explore hashing rates, power efficiency, and profitability calculations to understand the current landscape.
Our testing methodology focuses on out-of-the-box performance without BIOS modifications, representing what typical users might experience. The data provides comparative insights rather than investment advice, highlighting why certain graphics cards have become increasingly difficult to find at reasonable prices.
Test System Configuration
Hardware Setup
We utilized a modified X99 system to minimize overall power consumption while maintaining stable operation for multiple graphics cards:
| Component | Specification |
|---|---|
| CPU | Intel Core i7 6800k (2 cores/4 threads @ 1.2GHz) |
| Memory | 32GB CORSAIR Vengeance LPX DDR4 2133MHz |
| Motherboard | ASUS X99A-II |
| Storage | Crucial MX100 512GB SSD + Seagate 2TB SSHD |
| Power Supply | Cooler Master V1200 Platinum |
The system was optimized for efficiency rather than raw computing power, with CPU settings reduced to minimize energy consumption outside of GPU operations.
Mining Software Selection
After testing multiple options, we settled on Claymore's Miner for its compatibility with both AMD and NVIDIA cards without extensive configuration requirements. The software efficiently managed multiple GPUs while providing consistent hashing performance across different architectures.
Graphics Cards Tested
We evaluated eight popular graphics cards representing both AMD and NVIDIA's current offerings at the time of testing:
| GPU Model | Architecture | Core Count | Clock Speed | Memory | Memory Speed |
|---|---|---|---|---|---|
| NVIDIA GTX 1080 FE | Pascal | 2560 | 1607/1733 MHz | 8GB GDDR5X | 10Gbps |
| NVIDIA GTX 1070 FE | Pascal | 1920 | 1506/1683 MHz | 8GB GDDR5 | 8Gbps |
| NVIDIA GTX 1060 FE | Pascal | 1280 | 1506/1708 MHz | 6GB GDDR5 | 8Gbps |
| EVGA GTX 1050 SSC | Pascal | 640 | 1430/1544 MHz | 2GB GDDR5 | 7Gbps |
| XFX RX 480 | Polaris 10 | 2304 | 1266 MHz | 8GB GDDR5 | 8Gbps |
| Sapphire RX 570 | Polaris 20 | 2048 | 1340 MHz | 4GB GDDR5 | 7Gbps |
| Visiontek RX 470 | Polaris 10 | 2048 | 1226 MHz | 4GB GDDR5 | 7Gbps |
| Sapphire RX 460 Nitro | Polaris 11 | 896 | 1250 MHz | 4GB GDDR5 | 7Gbps |
All cards were tested at stock settings without modifications to represent typical user experiences rather than optimized mining configurations.
Performance Metrics Analysis
Hashing Performance
Our single-GPU testing revealed significant differences in Ethereum mining capabilities:
- AMD's Polaris architecture cards demonstrated superior hashing performance overall
- The RX 470 and RX 570 delivered particularly strong results relative to their price points
- NVIDIA's GTX 1070 performed remarkably well, nearly matching RX 570 hashing rates
- The GTX 1050 proved unable to mine Ethereum due to insufficient VRAM capacity
The hashing performance advantage of AMD cards explains their current market scarcity, as miners seek the most efficient hardware available.
Power Consumption Efficiency
While raw hashing power matters, energy efficiency ultimately determines long-term profitability:
- Polaris-based cards showed excellent performance per watt ratios
- The GTX 1070 demonstrated competitive efficiency despite lower absolute hashing rates
- Higher-end cards like the GTX 1080 showed diminishing returns due to increased power demands
Power measurements were taken at the wall after one hour of continuous mining to ensure accurate real-world data.
Profitability Calculations
Based on Ethereum's price of $169 at testing time (May 2017) and electricity costs of $0.12 per kWh:
- Mid-range AMD cards (RX 470, RX 570) showed the best profit potential
- The GTX 1070 presented a viable alternative for those unable to find AMD stock
- Higher-priced cards exhibited longer return on investment timelines

These calculations assume consistent mining conditions over 30 days, though cryptocurrency volatility makes long-term projections challenging.
Multi-GPU Configuration Results
Performance Scaling
Testing multiple graphics cards in various configurations revealed interesting dynamics:
- Dual Polaris card setups outperformed more expensive NVIDIA combinations
- The RX 470 + RX 570 configuration provided exceptional value relative to upfront cost
- Mixed NVIDIA setups (1080+1070+1060) showed higher hashing power but significantly greater investment requirements
Efficiency Considerations
Multi-GPU efficiency trends mirrored single-card results:
- Polaris configurations maintained their efficiency advantage at scale
- NVIDIA setups required more power for similar performance levels
- The cost of additional infrastructure (motherboards, power supplies) affected overall ROI calculations
Market Impact and Availability
The mining demand surge has created significant market distortions:
- RX 470/570/480 cards have become increasingly difficult to find at reasonable prices
- NVIDIA's GTX 1070 has emerged as a popular alternative despite higher initial cost
- Entry-level cards like the GTX 1050 remain available but unsuitable for Ethereum mining
This scarcity particularly affects gamers seeking these traditionally excellent value graphics cards, creating challenging purchasing decisions throughout the market.
Frequently Asked Questions
What makes certain GPUs better for Ethereum mining?
Ethereum mining relies heavily on memory bandwidth and computational efficiency. Cards with higher memory bandwidth and optimized architectures for parallel processing typically perform better. AMD's Polaris architecture specifically excels at the cryptographic calculations required for Ethereum mining.
How important is power efficiency for mining profitability?
Power efficiency is crucial because electricity costs directly reduce mining profits. A card that generates slightly lower hashing rates but consumes significantly less power may be more profitable long-term than a more powerful but less efficient alternative.
Can I use my gaming computer for mining when not gaming?
Yes, many users operate mining software during periods when they're not using their computers for other purposes. However, consider the increased wear on components and electricity costs when calculating potential profits.
Why are some graphics cards unavailable or overpriced?
High demand from miners has created shortages of particularly efficient models like the RX 470, RX 570, and RX 480. Limited supply combined with increased demand drives prices upward, making these cards difficult to find at manufacturer suggested retail prices.
How does cryptocurrency price volatility affect mining profitability?
Cryptocurrency values can fluctuate dramatically, directly impacting mining profitability. A setup that's profitable today might become unprofitable if coin values drop significantly or if mining difficulty increases substantially.
What's the minimum hardware requirement for Ethereum mining?
Ethereum mining requires a GPU with at least 4GB of VRAM (as of 2017 standards), a reliable power supply, and adequate cooling. The GTX 1050's 2GB memory made it unsuitable for Ethereum mining despite otherwise capable hardware specifications.
Conclusion
Our analysis demonstrates why certain graphics cards have become mining favorites despite their original design for gaming applications. The RX 470 and RX 570 offer exceptional efficiency and performance for Ethereum mining, explaining their current market scarcity. Meanwhile, the GTX 1070 presents a viable alternative for those unable to source AMD cards.
The cryptocurrency mining landscape continues to evolve rapidly, with hardware demands shifting alongside algorithm changes and market conditions. While this snapshot provides valuable insights, prospective participants should research current conditions and consider all associated costs before investing in mining hardware.
Understanding these performance characteristics helps explain current market conditions while providing context for both miners and gamers seeking graphics cards in a supply-constrained environment.
