As cryptocurrency values surge, many enthusiasts are turning to GPU mining as a profitable venture. This guide compares popular mining graphics cards, analyzes their efficiency, and provides actionable insights to maximize your ROI.
Why GPU Mining Matters Today
With ETH reaching ¥1,800 ($240B market cap) - nearly half of Bitcoin's valuation - mining has become increasingly attractive. Two primary methods exist:
- Purchasing through exchanges
- Mining with computational devices
Our tests focus on the latter, evaluating seven popular GPUs across critical performance metrics.

| GPU Model | Status |
|---|---|
| Radeon RX 560 | Limited stock |
| RX 470/RX 480 | Out of stock |
| GTX 1060/1070 | Scarce |
