The world of cryptocurrency mining continues to evolve, and GPU mining remains a compelling option for many enthusiasts—especially those focused on Ethereum and its ecosystem. While ASIC miners dominate Bitcoin mining, GPUs still play a vital role in proof-of-work networks like Ethereum, where algorithmic design favors parallel processing power.
Despite the anticipation around Ethereum 2.0 and the eventual shift to proof-of-stake, GPU mining remains profitable in 2025 due to strong network activity, DeFi growth, and stable coin valuations. But here's the truth: more expensive graphics cards aren’t automatically better for mining. The key lies in understanding return on investment (ROI), power efficiency, and future-proofing your setup.
Let’s break down how to choose the right GPU for mining—without overspending.
Understanding the Current Mining Landscape
Cryptocurrency mining has shifted dramatically over the years. Bitcoin mining is now dominated by specialized ASICs like Bitmain’s Antminer and MicroBT’s Whatsminer series. With Bitcoin’s network difficulty reaching record highs—exceeding 19.31 T and total hash rate surpassing 135.51 EH/s—consumer-grade GPUs are no longer viable for BTC.
However, Ethereum (ETH) remains highly accessible to GPU miners. Thanks to the Ethash algorithm, which is memory-hard and resistant to ASIC dominance, graphics cards continue to be effective tools for mining ETH and similar cryptocurrencies.
In fact, Ethereum’s network hash rate currently stands at approximately 256.221 TH/s—a slight decline from 2018 but still robust enough to support decentralized mining. Combined with a significant increase in ETH’s market value since early 2020, GPU mining profitability has surged.
“We expect continued demand for Ethereum mining well into 2025, driven by DeFi expansion and Layer-2 adoption,” notes a spokesperson from industry tracker WhatToMine.
Even with Ethereum 2.0 on the horizon, full transition timelines remain gradual. This gives miners ample time to generate returns—if they choose wisely.
Top GPUs for Mining in 2025
When selecting a mining GPU, focus on three core factors: hash rate, power consumption, and initial cost. Here are some of the most efficient and cost-effective options available today.
Nvidia GTX 1660 Super
Released in late 2019, the GTX 1660 Super remains a solid mid-tier option. Built on Turing architecture with 6GB GDDR6 memory, it delivers about 30 MH/s on Ethash while consuming only ~120W under load.
- Price: $240–$250
- Daily Earnings (Est.): $0.65
- Break-even Time: ~12 months
Its low power draw and decent performance make it ideal for small-scale or beginner mining rigs.

AMD Radeon RX 5700 / RX 5700 XT
Launched in 2019, these RDNA-based cards offer excellent efficiency. The RX 5700 delivers around 34 MH/s at 180W, while the XT model pushes up to 42 MH/s at 225W.
- Price: ~$400
- Daily Earnings (Est.): $1.56 (XT)
- Break-even Time: ~8.5 months (XT)
These cards strike a great balance between performance and energy efficiency—perfect for multi-GPU farms where power costs matter.
Nvidia RTX 2060 Super
With 8GB VRAM and support for multiple algorithms—including DaggerHashimoto (Ethereum), GrinCuckarooD29, and BeamV2—the RTX 2060 Super is versatile and reliable.
- Hash Rate: ~36 MH/s
- Power Draw: ~140W
- Daily Earnings (Est.): $0.92
- Break-even Time: ~14 months
Priced at $399, it sits between the 2060 and 2070 in performance but offers better value than both.
AMD Radeon RX 580
A classic budget favorite. Despite being released in 2017, the RX 580 with 8GB memory still performs well on Ethash, delivering 28–30 MH/s at ~185W.
- Price: $180–$230
- Daily Earnings (Est.): $0.96
- Break-even Time: ~7 months
This card offers one of the fastest ROI periods among older models—making it ideal for cost-conscious miners.
⚠️ Warning: Avoid 4GB versions. Ethereum’s DAG file size will soon exceed their memory capacity, rendering them obsolete.
Nvidia P106-100 “Mining Edition”
Designed specifically for mining, this stripped-down version of the GTX 1060 lacks display outputs and cooling shrouds—reducing cost and improving airflow in dense rigs.
- VRAM: 6GB
- Hash Rate: ~26 MH/s
- Price: $320
- Daily Earnings (Est.): $0.85
- Break-even Time: ~12 months
Though not faster than consumer cards, its optimized form factor makes it suitable for dedicated mining chassis.
How to Choose the Right Mining GPU
Profitability isn’t just about raw speed—it’s about cost efficiency over time. Consider this comparison:
| GPU Model | Cost | Daily Profit | ROI Period |
|---|---|---|---|
| RX 580 (8GB) | $200 | $0.96 | ~7 months |
| RX 5700 XT | $400 | $1.56 | ~8.5 months |
| GTX 1660 Super | $245 | $0.65 | ~12 months |
| RTX 2060 Super | $399 | $0.92 | ~14 months |
| P106-100 | $320 | $0.85 | ~12 months |
As shown, the RX 580 provides the quickest return, despite being one of the oldest options. Meanwhile, high-end cards like the RTX 2080 Ti may generate $1.66/day but require over two years to recoup costs—even before electricity expenses.

What About New GPUs?
Nvidia’s RTX 30-series brought major improvements. The RTX 3060 Ti achieves up to 60 MH/s, while the RTX 3090 reaches 120 MH/s, making them top performers. However, scarcity and inflated prices due to demand from gamers and AI developers have limited accessibility.
AMD isn’t far behind. Its RDNA 2 lineup—including the RX 6700 XT and RX 6800 series—delivers competitive hash rates with improved power efficiency.
Still, unless you can buy at MSRP, older or mid-range GPUs often provide better ROI.
Frequently Asked Questions (FAQ)
Q: Is GPU mining still profitable in 2025?
A: Yes—especially for Ethereum and other memory-hard coins. While rewards are lower than peak bull markets, consistent network usage and coin value support ongoing profitability.
Q: Will Ethereum 2.0 kill GPU mining?
A: Eventually, yes—but not immediately. The full transition will take time, and partial PoW validation may persist through Layer-2 solutions or sidechains.
Q: Should I mine with new or used GPUs?
A: Used cards like the RX 580 offer faster ROI if in good condition. Just avoid damaged or heavily worn units typically sold by retired mining farms.
Q: How does electricity cost affect mining profits?
A: Significantly. A card drawing 200W at $0.10/kWh adds ~$48/month in power costs. Always calculate net profit after energy expenses.
Q: Can I use gaming GPUs for mining?
A: Absolutely—but prolonged use under load may reduce lifespan. Dedicated mining models (like P106-100) are built for endurance.
Q: Is cloud mining a better alternative?
A: For beginners, yes. Cloud services eliminate hardware risks and maintenance hassles. You pay for hash rate rental and receive daily payouts—ideal for passive income seekers.
