Cryptocurrencies like Bitcoin (BTC), Litecoin (LTC), and Ethereum (ETH) have revolutionized digital finance. With the right hardware, mining these coins can be profitable. This guide explores the optimal graphics cards for crypto mining in 2017, focusing on efficiency, power consumption, and ROI.
Key Factors in Choosing a Mining GPU
- Hash Rate: Measured in MH/s (mega-hashes per second), higher values mean better mining performance.
- Power Efficiency: Lower wattage per hash rate reduces electricity costs.
- GPU Memory: At least 4GB VRAM is required for most algorithms (e.g., Ethereum’s Dagger-Hashimoto).
- Cost vs. ROI: Balance upfront GPU costs with projected earnings.
Top Mining GPUs of 2017
NVIDIA Cards
| GPU | Hash Rate (MH/s) | Power (W) | Notes |
|---|---|---|---|
| GTX 1050 | 0 | 75 | 2GB VRAM insufficient |
| GTX 1060 | 22 | 120 | Budget-friendly |
| GTX 1070 | 30 | 150 | Outperforms GTX 1080 |
| GTX 1080 | 25 | 180 | G5X VRAM lacks mining boost |
AMD Cards
| GPU | Hash Rate (MH/s) | Power (W) | Notes |
|---|---|---|---|
| RX 460 | 12 | 75 | Entry-level |
| RX 470 | 24–28 | 120 | Best value for miners |
| RX 480 | 24–29 | 150 | Reliable performer |
| RX 570 | 25–30 | 150 | Slightly improved architecture |
Why Choose AMD Over NVIDIA?
- Stream Processors: AMD’s architecture excels in parallel tasks like hashing.
- Cost Efficiency: Higher hash rates per dollar spent.

- Considerations: Power supply capacity, cooling, and motherboard compatibility.
Profitability Analysis (May 2017)
| GPU | Daily Earnings (ETH) | Electricity Cost |
|---|---|---|
| RX 470 | 0.015 | $0.10 |
| GTX 1070 | 0.012 | $0.12 |
Assumptions: ETH = $169, electricity = $0.10/kWh.
FAQs
1. Is GPU mining still profitable in 2017?
Yes, but ROI depends on electricity costs and coin value fluctuations. AMD RX 470 offers the best balance.
2. Why does GTX 1070 outperform GTX 1080 in mining?
GDDR5X memory in the 1080 provides no advantage for mining algorithms, while the 1070’s GDDR5 optimizes hash rates.
3. How much VRAM is needed for Ethereum mining?
At least 4GB, as Dagger-Hashimoto requires ~3GB for the DAG file (2017 data).
4. Should I use multiple GPUs?
Yes, but ensure your PSU and cooling can handle the load. Multi-GPU setups like GTX 1080+1070+1060 maximize long-term gains.
5. What’s the most power-efficient NVIDIA card?
The GTX 1060 (22 MH/s at 120W) strikes a good balance.
Final Thoughts
The AMD RX 470 emerged as the top choice for miners in 2017 due to its high hash rate, low power draw, and affordability. NVIDIA’s GTX 1070 also proved viable for those prioritizing energy efficiency.
