Crypto mining is still an interesting way to make money in 2025, and video cards (or GPUs) are a key tool for those who want to build a mining rig and join this activity. Although it is not as popular as in 2020, when during the pandemic interest in mining cryptocurrencies such as Bitcoin or EthereumThere are still opportunities if you choose the right hardware. In this article, we'll tell you which are the best graphics cards for mining, what to consider when purchasing one, and how to balance costs and profits in a market where GPU prices remain high, especially in countries where they must be imported.
In my opinion, mining had its heyday a few years ago, but in 2025 it's still an option for generating income. It did, however, create a problem: GPU prices rose sharply, and we're still feeling it.Mining puts a strain on graphics cards, so you have to find a balance between how much you want to earn and how much you're willing to spend or risk. I was using an RTX 3080 Ti, limiting it so it wouldn't overheat (I also used it for gaming), and I was making about $200 a month from Ethereum.. It's still possible today, although less profitable, and it requires dedication, like any investment.
Why use graphics cards to mine cryptocurrencies?
Mining cryptocurrencies is like solving math puzzles to validate transactions on a blockchain network, and GPUs are perfect for that because they process many calculations at once. Unlike Antminers either ASIC equipment (like the Bitmain Antminer S19 Pro, ideal for Bitcoin), graphics cards are more versatile: you can use them to mine different cryptocurrencies, such as Ethereum Classic, Ravencoin, or Ergo, and you're not limited to a single algorithm. This makes them ideal for those building mining rigs at home or looking for a graphics card to mine cryptocurrencies without investing in specialized equipment. Plus, if you stop mining one day, you can use them for gaming or work.
The best graphics cards for mining in 2025
Based on power, efficiency, and price, these are the top options for building your mining rig this year. We include everything from modern models to budget-friendly used options to suit a variety of budgets.
NVIDIA RTX 4090
- Why choose it: It is the queen of mining in 2025. With a hashrate of around 120 MH/s in algorithms like ETHash, it is the most powerful on the market.
- Advantages: Its 24GB GDDR6X is ideal for cryptos that need a lot of memory, and its performance makes it a leader in graphics cards for mining.
- Disadvantages: It costs between $1500 and $2000 USD, a high price that takes time to recover, especially if you import from countries like Argentina.
- Ideal forSerious miners with large mining rigs and cheap electricity.
AMD RX 6700 XT
- Why choose it: It offers a decent hashrate (45 MH/s) at a much lower cost ($300-$400 USD).
- Advantages: Good energy efficiency (230W) and an affordable price, perfect as a cheap graphics card for mining.
- Disadvantages: With 12GB GDDR6, it's less future-proof than the RTX 4090 for heavy crypto.

NVIDIA RTX 3060 Ti
- Why choose it: A classic option with 60 MH/s and a reasonable price ($250-$350 USD, even used).
- Advantages: Its balance between cost and performance makes it one of the best graphics cards for mining on a mid-range budget.
- Disadvantages: Only 8GB GDDR6, which may limit it on some modern algorithms.
- Ideal for: Miners who want a reliable and not so expensive mining graphics card.
NVIDIA RTX A5000
- Why choose it: Recommended by experts such as Stec, with 90 MH/s and low consumption (200W).
- Advantages: Its 24GB GDDR6 and efficiency make it stand out among cryptocurrency mining graphics cards.
- Disadvantages: It costs between $1000 and $1200 USD, more focused on professional use.
- Ideal for: Advanced miners that prioritize efficiency in their cryptocurrency rigs.
NVIDIA RTX 4060 Ti
- Why choose it: : Recent model with 50-55 MH/s and better efficiency than previous generations ($400-$500 USD).
- Advantages: Low power consumption (160W) and modern technology, a solid choice among cryptocurrency boards.
- Disadvantages: 8GB GDDR6 and a somewhat high price for its hashrate.
- Ideal forMiners who want a new GPU with a good power-performance balance.
AMD RX 580
- Why choose it: A budget veteran with 28-30 MH/s ($80-$120 USD, used).
- Advantages: Very cheap and still functional, ideal as a video card used for mining.
- Disadvantages: : 8GB GDDR5 and high consumption (150W) make it less efficient.
- Ideal for: Beginners or small rigs on a budget.
How much can you earn mining with these boards?
Profitability depends on the cost of electricity, the cryptocurrency you mine, and the price of the GPU. Here's a rough example with an electricity cost of $0.10 per kWh: In Argentina the cost of kWh is $111ARS:
| Plate | Hashrate (ETHash) | Consumption | Daily earnings (approx.) |
|---|---|---|---|
| RTX 4090 | 120 MH/s | 400W | $1.50 – $2.00 |
| RX 6700 XT | 45 MH/s | 180W | $0.60 – $0.80 |
| RTX 3060 Ti | 60 MH/s | 200W | $0.80 – $1.00 |
| RTX A5000 | 90 MH/s | 200W | $1.20 – $1.60 |
| RTX 4060 Ti | 55 MH/s | 160W | $0.70 – $0.90 |
| RX 580 | 30 MH/s | 150W | $0.40 – $0.60 |
These profits are lower than in 2020 because many cryptocurrencies, such as Ethereum, have switched to systems that don't require GPU mining. However, coins like Ravencoin and Ergo are keeping this practice alive. I limited my RTX 3080 Ti so as not to wear it out too much, and although today I wouldn't get as much as before, it is still a possible source of income if you find the right balance..
What power supply do you need for your rig?
The font size depends on how many boards you use. For a rig with an RTX 4090:
- CPU: Ryzen 5 5600X (95W).
- GPU: RTX 4090 (450W).
- Others: Motherboard, SSD, RAM and fans (~80W).
- Total: 625W.
- With margin (30%): ~850W.
- Recommendation: A Corsair RM850x (850W, ~$130) is perfect. For an RX 580 (total ~300W), a Corsair CV450 (450W, ~$40) is enough.
Is it worth mining with graphics cards in 2025?
Yes, but with nuancesMining puts a strain on graphics cards, and the high prices of modern GPUs like the RTX 4090 make it difficult to recover. In countries like Argentina, where graphics cards for mining cryptocurrencies are often imported, the initial cost is a challenge. That's why options like the RX 6700 XT or a graphics card used for mining like the RX 580 are more practical. Compared to equipment like the Antminer S19 (ideal for Bitcoin with 110 TH/s), GPUs are less powerful but more flexible.
Conclusion: Which board is best for you?
Choosing between the best graphics cards for mining depends on your budget and goals. RTX 4090 It is the better for mining on a large scale, but its price is an obstacleFor something more accessible, the RX 6700 XT, RTX 3060 Ti or even an RX 580 used are ideal for start a mining rig without breaking the bank. In my case, mining with a 3080 Ti gave me decent profits by limiting its power, and I think it's still viable in 2025 if you look for a balance between what you invest and what you earn. It's like any investment: putting in the time and choosing the right hardware can pay off.
Frequently Asked Questions about Crypto Mining with Graphics Cards
Basic concepts
A mining rig is a device with several connected graphics cards for mining cryptocurrencies, like a small home computing center.
An Antminer (like the Bitmain Antminer S19 Pro) is a specialized rig for mining Bitcoin, while GPUs are more versatile for other cryptos like Ravencoin.
In 2025, you can mine coins like Ravencoin, Ergo, or Ethereum Classic, since Bitcoin requires ASICs like the Antminer S19.
Performance and earnings
The RTX 4090 is the most powerful (120 MH/s), but the RX 6700 XT or RTX 3060 Ti are more cost-effective for their price ($300-$400 USD).
With an RTX 4090, it's between $1.50 and $2 per day; with an RX 580, it's $0.40-$0.60, depending on power and crypto.
Yes, if electricity is cheap, but the high prices of imported GPUs make it difficult to recover the investment quickly.
Hardware and configuration
For an RTX 4090, an 850W PSU (e.g. Corsair RM850x, ~$130); for an RX 580, a 450W PSU (e.g. Corsair CV450, ~$40).
Yes, constant use wears them out, but limiting the power, as I did with my 3080 Ti, helps them last longer.
Yes, if it's in good condition. A used RX 580 (~$$100) is still useful for basic mining.
