Cryptocurrencies like Bitcoin (BTC), Dogecoin (DOGE), and Ethereum (ETH) continue to dominate financial headlines. As digital asset values rise, GPU mining has regained popularity due to improved profitability—especially for Ethereum-based mining. With so many graphics cards on the market, how do they compare in terms of mining performance and return on investment? This guide breaks down the top GPUs for Ethereum mining, their hashrates, daily earnings, and estimated payback periods—all based on real-world benchmarks.
All testing was conducted using a consistent platform: Intel Core i9-9900K CPU, MSI MEG Z390 ACE motherboard, 2x16GB Corsair DDR4-3600 RAM, 2TB XPG M.2 SSD, and a Seasonic 850W 80 Plus Platinum power supply. This ensures accurate and comparable results across all GPU models.
Top GPUs for Ethereum Mining: Performance & Profitability
When evaluating mining profitability, three key factors matter most: hashrate, power consumption, and current market price. While higher-end cards deliver superior performance, their premium pricing can extend the break-even timeline. Let’s explore the top-performing GPUs based on ETH mining efficiency.
High-End Mining Cards
These flagship models lead in raw performance but come with steep price tags.
- NVIDIA RTX 3090 – Delivers an impressive 125.0 MH/s, earning approximately $13.32 per day. At a reference price of $4,199, it takes about 315 days to recoup costs.
- NVIDIA RTX 3080 – Offers 100.0 MH/s with daily returns of $10.65. Priced around $3,200, its break-even point is roughly 300 days.
- AMD Radeon VII – A strong contender at 95.0 MH/s and $10.12 daily income. With a lower cost of $1,999, it reaches ROI in just 197 days, making it one of the better value options in the high-tier segment.

Mid-Range Powerhouses
Balancing cost and performance, these cards are ideal for miners seeking efficient setups without breaking the bank.
- AMD RX 6800 XT & RX 6900 XT – Both achieve 65.0 MH/s and earn $6.92 daily. However, the RX 6800 XT offers better value at $1,600 compared to the $2,000 RX 6900 XT.
- NVIDIA RTX 3060 Ti & RTX 3070 – Match each other at 60.0 MH/s and $6.39/day. The RTX 3060 Ti is slightly more cost-effective at $1,620 versus $1,759.
- AMD RX 5700 XT & RX 5700 – Offer nearly identical performance (~56 MH/s) and daily earnings (~$6.00). Both have attractive ROI timelines under **200 days**, thanks to sub-$1,200 pricing.
Budget-Friendly Options
For those starting out or building multi-GPU rigs economically, these cards offer solid returns.
- NVIDIA RTX 2070 SUPER & RTX 2060 SUPER – Deliver 44.3 MH/s and $4.72/day. The RTX 2060 SUPER stands out at $799, achieving ROI in 169 days.
- GTX 1080 Ti – Still relevant with 43.5 MH/s and $4.63/day earnings. At only $580, it pays for itself in just 125 days, making it one of the most efficient older-generation cards.
- P104-100 & GTX 1080 – Both produce 35.5 MH/s and $3.78/day. The P104-100 edges ahead with a $480 price tag and 126-day ROI.
Entry-Level & Legacy Cards
While less powerful, some older or low-memory GPUs can still be viable for alternative coins.
Note: Cards with 0 MH/s for ETH are incompatible with Ethereum mining due to memory limitations (e.g., <4GB VRAM). However, they may still mine other cryptocurrencies like Ravencoin or Ergo.
Examples:
- P106-100: 22.5 MH/s (on supported algorithms), $2.40/day
- GTX 1650 / RX 550: No ETH mining capability but useful for lightweight PoW coins
Key Factors Beyond Hashrate
While hashrate is crucial, focusing solely on speed can mislead investors. Consider these additional elements:
Power Efficiency
A card might deliver high hashrate but consume excessive electricity—eroding profits. Always calculate net earnings after power costs (typically $0.10–$0.15/kWh).
Market Price Volatility
Cryptocurrency prices fluctuate daily. The current ETH price significantly impacts daily revenue and ROI timelines.
Hardware Availability & Resale Value
Some models are scarce or sold above MSRP. Consider long-term resale potential when choosing hardware.

Frequently Asked Questions
Q: Why do some GPUs show 0 MH/s for Ethereum?
A: Ethereum's Ethash algorithm requires at least 4GB of VRAM to process mining tasks efficiently. GPUs with less memory or certain OEM variants cannot meet this requirement and thus return zero hashrate.
Q: Is GPU mining still profitable in 2025?
A: Yes—though less dominant than before, GPU mining remains viable for altcoins like Ravencoin (RVN), Ergo (ERG), and Conflux (CFX). Ethereum Classic (ETC) also supports GPU mining post-merge.
Q: How does power consumption affect profitability?
A: Higher wattage increases electricity costs. For example, a GPU drawing 300W at $0.12/kWh adds ~$8.64/day in energy costs. Always subtract this from gross earnings to determine net profit.
Q: Can I use multiple GPUs in one rig?
A: Absolutely. Many miners build multi-GPU systems (e.g., 6–8 cards) using PCIe risers and mining motherboards. Ensure adequate PSU capacity and cooling.
Q: What happens to mined coins after extraction?
A: Mined coins are sent to your wallet via a mining pool or solo setup. Using a secure non-custodial wallet ensures full control over your assets.
Q: Are ASICs replacing GPUs completely?
A: For Bitcoin and some algorithms, yes—but many proof-of-work blockchains remain ASIC-resistant to preserve decentralization and allow fair GPU participation.
Maximizing Your Mining Strategy
To optimize returns:
- Monitor coin profitability using tools like WhatToMine or MinerStat.
- Join reliable mining pools with low fees and consistent payouts.
- Keep drivers updated and fine-tune core/memory clocks for better efficiency.
- Use undervolting techniques to reduce power draw without sacrificing performance.
Mining isn't just about raw speed—it's about smart resource allocation and staying informed.

Final Thoughts
GPU mining remains a dynamic and accessible entry point into the world of cryptocurrency. While Ethereum's shift to proof-of-stake reduced demand for ETH mining, numerous alternative coins keep GPU rigs relevant and profitable.
Whether you're investing in a high-end RTX 3090 or repurposing older GTX models, understanding hashrate, power usage, and market pricing is essential for success.
By choosing the right hardware and pairing it with sound financial planning, you can build a sustainable mining operation that adapts to evolving blockchain landscapes.
