GPU for Mining 2025–2026: Choosing Graphics Cards for Cryptocurrency Mining

Mining hardware market remains one of the most accessible and flexible solutions for earning on the blockchain. With the release of new generations of graphics cards in 2025 and the emergence of fresh AMD RDNA 4 models, miners face the question: which mining GPUs should they choose? We have prepared an up-to-date equipment ranking with detailed analysis of specifications, costs, and profitability.

Flagship mining graphics cards: maximum performance

If you’re aiming for professional income, start with the premium segment. Here, the most powerful mining GPUs operate, capable of taking your farm to a new level.

NVIDIA RTX 5090: absolute performance leader

The NVIDIA GeForce RTX 5090 2025 release has become the flagship solution for crypto mining. This device has literally rewritten performance standards:

The RTX 5090 is the choice for those ready to invest large capital and expect long-term returns. On complex algorithms requiring large video memory (like Kaspa with DAG over 15 GB), this card shows absolute advantage. One downside: its power consumption (~575 W) demands serious cooling infrastructure and a robust PSU.

NVIDIA RTX 5080: optimal premium balance

If RTX 5090 is for large farms, the NVIDIA GeForce RTX 5080 suits miners with a good budget but more cautious spending:

The RTX 5080 appears as a compromise: it costs half as much as the top model, consumes half as much electricity, but loses about 40% in performance. For a farm of 10-15 cards, this math can be much more attractive.

AMD RX 9070 XT: best price/performance ratio in premium segment

Mining GPUs from AMD based on RDNA 4 architecture brought an interesting turn. The RX 9070 XT demonstrates impressive performance at half the price of NVIDIA:

Main advantage — energy efficiency. With similar ETC performance (216 vs. 215 MH/s), the RX 9070 XT consumes half as much power: 304 W versus 575 W. This means significant savings on electricity and cooling. Ideal for regions with high electricity rates.

Mid-level mining GPUs: balance of price and power

Not everyone is ready to invest $1000+ in a single card. Here, solutions that provide acceptable income with reasonable investments are relevant.

AMD RX 9070: budget RDNA 4 option

For those wanting AMD but at a lower price:

The RX 9070 without the “XT” suffix is an economical version for budget miners. Power consumption drops to 220 W, making it ideal for home farms. Performance is good — 180 MH/s on ETC, but if difficulty increases on this algorithm, the card may switch to other coins.

Proven models: reliable solutions for crypto mining

History has shown that not always the newest is the best. Previous generation GPUs remain relevant due to their reliability and affordable secondhand prices.

NVIDIA RTX 4090: king of 2022–2024

Although released in 2022, the RTX 4090 remains the gold standard:

Initially, RTX 4090 was out of reach for most, but the secondary market is now filled with devices that left “Ethereum farms” after migrating to PoS in September 2022. Good units can be found cheaper. Key point — check the card’s history (not used 24/7 under maximum load without breaks).

NVIDIA RTX 4070 Ti: the sweet spot of previous generation

For those wanting RTX 4090 power at half the price:

The RTX 4070 Ti offers good efficiency: 1.1 GH/s on Kaspa at 285 W. For small farms, this may be more optimal than a single high-end card.

Budget workhorses: RTX 3080 and RTX 3060 Ti

Don’t dismiss 2020–2021 cards. On the secondary market, they are still viable:

NVIDIA RTX 3080 (2020):

• Memory: 10 GB
• Power: ~310–320 W
• Ethereum Classic: ~95–100 MH/s
• Used price: ~$400

NVIDIA RTX 3060 Ti (2020):

• Memory: 8 GB
• Power: ~190–200 W
• Ethereum Classic: ~60 MH/s
• Used price: ~$200–250

For beginners or small home farms, the RTX 3060 Ti remains a viable option. With current electricity prices, it can pay off in 6–12 months depending on the region.

AMD: proven RDNA 2 and RDNA 3

AMD RX 7900 XTX (2022): flagship of AMD’s old generation:

• Memory: 24 GB GDDR6
• Power: ~345–355 W
• Ethereum Classic: ~101 MH/s
• New price: ~$800–900; used: ~$600–700

AMD RX 6800 XT (2020): workhorse:

• Memory: 16 GB GDDR6
• Power: ~290–300 W
• Ethereum Classic: ~65 MH/s
• Used price: ~$300–350

AMD RX 6600 XT (2021): economical:

• Memory: 8 GB GDDR6
• Power: ~155–160 W
• Ethereum Classic: ~32 MH/s
• New price: ~$200; used: ~$150–170

How to choose a mining GPU: main criteria

Ask yourself three questions:

1. What is your budget?
   If $200–500, look for used RTX 3060 Ti or RX 6600 XT.
   If $2000+, consider new RTX 5090/5080 or RX 9070 XT.

2. Which coins do you plan to mine?
   For DAG-intensive algorithms (Kaspa, ETC), more VRAM is needed.
   For SHA-256 (Bitcoin via NiceHash), any GPU will do.

3. What is your region and electricity rate?
   At rates above $0.10/kWh, choose energy-efficient models (RX 9070, RTX 3060 Ti).
   At $0.05/kWh, even RTX 5090 can be profitable.

Profitability and ROI: crypto mining math on GPUs

Actual ROI depends on four variables:

• Hardware cost: total price of the card
• Power consumption: TDP (close to real usage)
• Hashrate: performance on selected algorithm
• Network difficulty and coin price: change daily

For quick estimates, use platforms:

Whattomine — select GPU, algorithm, input electricity cost, get daily/monthly/yearly earnings.

NiceHash calculator — input GPU, see current hash rates, potential income.

Real examples:

• RTX 5090 at $0.08/kWh on Kaspa: ~$25–35/day (~9–12 months ROI)
• RX 9070 XT at $0.08/kWh on ETC: ~$8–10/day (~24–30 months ROI)
• Used RTX 3060 Ti at $0.08/kWh on ETC: ~$2–3/day (~3–4 months ROI)

Cheaper used cards have shorter ROI but lower absolute income.

Major market shift: what happened after Ethereum PoS in 2022

On September 15, 2022, Ethereum (ETH), the second-largest crypto by market cap, transitioned from Proof-of-Work (PoW) to Proof-of-Stake (PoS). This event reshaped the GPU mining landscape.

Until that day, miners dreamed of Ethereum — Ethash algorithm optimized for GPUs. After, migration occurred to Ethereum Classic (ETC), Ravencoin (RVN), Kaspa, and Beam (BEAM). Due to mass influx, network difficulty increased 3–5 times, and profitability dropped sharply.

Many GPUs, including RTX 3060 Ti and RX 6600 XT, suddenly became unprofitable at electricity rates above $0.12/kWh. The secondary market flooded with used equipment. For a time, it seemed GPU mining era was over.

But over time, miners adapted. They found less popular but profitable coins. New algorithms requiring powerful GPUs appeared. Mining GPUs again became economically viable.

Which cryptocurrencies can be mined on a GPU in 2025–2026

Relevant coins for GPU mining:

• Kaspa (KAS) — DAG-intensive, needs 15+ GB VRAM, good hash rates
• Ethereum Classic (ETC) — stable, high memory requirements
• Ravencoin (RVN) — moderate power consumption, accessible to beginners
• Dogecoin (DOGE) — via pools, predictable income
• Bitcoin (BTC) — via NiceHash (SHA-256), low GPU hash rates but demand exists

Choice depends on three factors: DAG file size (fits in your card’s memory), coin price, network difficulty.

Understanding mining: theory and practice

What is mining

Mining is the process of creating new units of cryptocurrency by solving complex computational problems, confirming transactions, and earning rewards in crypto coins.

Simple example: Bitcoin network constantly generates tasks (finding a hash satisfying conditions). If your computer (miner) solves this first or helps solve it, the network rewards you with BTC.

GPU as a mining tool

GPUs excel at parallel computations better than CPUs. For algorithms like Ethash (Ethereum) or Kaspa, frequent access to large memory is needed. GPUs are designed for this. One GPU can perform billions of operations per second, making it ideal for mining.

Alternative crypto extraction methods

Alongside GPU mining, there are:

• ASIC mining — specialized chips for specific algorithms (e.g., Bitcoin). More powerful but less versatile and more expensive.
• CPU mining — using processors. Ineffective for most algorithms.
• Staking — holding coins in a wallet/validator to earn rewards instead of mining.

Where and how to buy mining GPUs

New mining graphics cards

Where to buy: Avito (Russia), OLX, marketplaces (OZON, Yandex.Market), miner forums, local ads.

Tip: Request test results (GPU-Z, MemTest), ensure card wasn’t used 24/7 under maximum load.

Mining setup: from single card to farm

Start with one GPU on a home PC. If profitable, scale:

• One GPU — gaming PC with mining software
• 2–5 GPUs — small rig (dedicated mining PC)
• 10+ GPUs — farm (requires dedicated space, high-capacity power supply, cooling)

For farm operation, need:

• High-capacity PSUs (1000–2000 W)
• PCIe cables and adapters
• Cooling systems (fans, AC)
• Mining software (Ethminer, NBMiner, HiveOS)
• Crypto wallet for payouts
• Voltage stabilizers to prevent surges

Conclusion

Mining GPUs in 2026 remain a viable earning method, but require careful calculation. Choosing between a $2000 RTX 5090 and a $250 used RTX 3060 Ti depends on your capital, patience, and regional conditions.

Recommendations:

• Professionals with large capital: RTX 5090/5080 or RX 9070 XT — maximum performance, long-term prospects.
• Mid-level miners: Used RTX 4090 or RX 9070 — optimal price-performance-energy efficiency.
• Beginners with limited budget: Used RTX 3060 Ti or RX 6600 XT — low risk, quick ROI, good experience.

Before investing, calculate ROI via Whattomine, considering local electricity rates. Remember: mining is more profitable where electricity is cheaper.
