With the fluctuating landscape of cryptocurrency, many enthusiasts and tech-savvy individuals are curious about the best graphics cards for mining. While profitability has decreased significantly since the peaks of 2021, understanding GPU mining performance remains relevant for those with existing hardware or those considering entering the space cautiously.
This analysis ranks popular GPUs based on hashing performance, power efficiency, and estimated break-even time under early 2022 market conditions. Note that cryptocurrency values and mining difficulty change constantly—always verify current numbers before making decisions.
Understanding Cryptocurrency Mining Today
Cryptocurrency mining uses computing hardware to validate transactions on blockchain networks. This process requires solving complex mathematical problems, with successful miners earning rewards in the form of crypto tokens. Ethereum has been the most popular choice for GPU miners due to its algorithm, though this may change with its planned transition to proof-of-stake.
Mining profitability depends on several factors:
- Hash Rate: The speed at which a GPU solves cryptographic puzzles (measured in megahashes per second, MH/s).
- Power Consumption: Electricity usage significantly impacts net earnings.
- Coin Value: The market price of the mined cryptocurrency.
- Network Difficulty: How hard it is to mine based on total network competition.
Ethereum Mining Performance Benchmarks
We tested numerous GPUs using a standardized mining setup: Core i9-9900K CPU, Z390 motherboard, 32GB DDR4-3600 RAM, and an 850W 80 Plus Platinum PSU. Each card was optimized for maximum hash rate while minimizing power draw. Power measurements were taken at the wall to ensure accuracy.
Our calculations assume:
- Ethereum as the mined cryptocurrency
- $0.10 per kWh electricity cost
- January 2022 eBay sold prices for GPUs
- Current network difficulty at time of testing

Top Mining GPU Recommendations
Based on our testing, these models offer the best balance of performance and efficiency for Ethereum mining:
GeForce RTX 3060 Ti
This card delivers exceptional mining efficiency, achieving over 60MH/s while consuming under 120W. The non-LHR (Lite Hash Rate) models perform significantly better for mining—avoid LHR versions if possible. 👉 Check current mining performance metrics
Radeon RX 5600 XT
AMD's previous-generation Navi architecture proves very capable for mining. The RX 5600 XT reaches approximately 40MH/s with 115W power consumption. The RX 5500 XT 8GB offers similar efficiency at a slightly lower performance level.
GeForce RTX 2060 Super
All RTX 20-series cards with 8GB memory achieve similar mining performance (~44MH/s). The RTX 2060 Super typically offers the best value among these models, though pricing fluctuations may change this calculation.
Radeon RX 570 8GB
Polaris-based cards with 8GB memory (including RX 580, RX 590) provide solid entry-level mining performance. Memory overclocking capabilities vary between individual cards, but these models generally offer good value when found at reasonable prices.
Important Mining Considerations
Hardware Longevity
Running GPUs for mining 24/7 significantly reduces their lifespan. Fans, VRMs, and other components may fail prematurely under constant thermal stress. Many manufacturers void warranties for cards used for mining.
Electricity Costs
Power consumption dramatically affects profitability. At $0.10 per kWh, electricity typically consumes 30-50% of mining revenue. Higher electricity rates make many operations unprofitable.
Market Volatility
Cryptocurrency values change rapidly—sometimes dropping 50% or more in weeks. This volatility means break-even calculations can become obsolete quickly. Never invest more than you can afford to lose completely.
Ethereum 2.0 Transition
Ethereum's planned move to proof-of-stake will eliminate mining entirely for this cryptocurrency. While repeatedly delayed, this transition remains imminent and will fundamentally change GPU mining economics.
Frequently Asked Questions
How much can I really earn with GPU mining today?
Current daily earnings range from $0.70 to $4.00 for most GPUs, before electricity costs. After subtracting power expenses, net profits are typically 30-50% lower. These figures change constantly with cryptocurrency values and network difficulty.
Is mining still worth starting in 2024?
For most people, purchasing cryptocurrency directly is more cost-effective than mining. Mining only makes financial sense if you have extremely cheap electricity, free hardware, or strong belief in long-term cryptocurrency appreciation.
What is LHR and why does it matter?
LHR (Lite Hash Rate) is Nvidia's technology that limits cryptocurrency mining performance on certain GPUs. Non-LHR cards typically achieve 25-50% higher mining performance, making them significantly more valuable for miners.
How does mining affect my gaming performance?
Mining requires dedicated GPU resources—you cannot game while mining effectively. However, stopping mining during gaming sessions causes no permanent performance degradation. Extended mining use may reduce card lifespan.
What alternatives exist if Ethereum moves to proof-of-stake?
Other mineable cryptocurrencies include Ravencoin, Ethereum Classic, and Ergo. However, none currently offer comparable profitability to Ethereum, and massive miner migration would likely decrease earnings across all these networks.
Should I buy used mining GPUs?
Used mining cards may have reduced lifespan due to constant thermal cycling. However, many miners undervolt their cards, potentially causing less damage than gaming use. Always test thoroughly and expect shorter usable life.
Conclusion
GPU mining remains a technically interesting but financially risky endeavor. The best mining graphics cards balance hash rate with power efficiency, though current market conditions make break-even periods extended—typically over one year even in optimistic scenarios.
While the GeForce RTX 3060 Ti and Radeon RX 5600 XT currently lead in efficiency, all mining operations face significant challenges from cryptocurrency volatility, rising network difficulty, and Ethereum's impending protocol changes. 👉 Explore advanced mining strategies
For most enthusiasts, mining should be approached as a hobby rather than an investment strategy. The era of guaranteed profits from GPU mining has passed, and successful operations now require sophisticated cost management and risk mitigation strategies. Always research current conditions thoroughly and never invest more than you can afford to lose completely.
