Cryptocurrency mining has evolved from a niche hobby into a high-stakes technological pursuit. While buying digital assets like Bitcoin and Ethereum from exchanges remains the most accessible route, many enthusiasts still opt to mine these currencies using powerful hardware. At the heart of every successful mining rig lies a high-performance graphics processing unit (GPU). These GPUs handle the complex mathematical computations required to validate transactions and secure blockchain networks.
If you're considering entering the world of crypto mining, choosing the right graphics card is critical. Not all GPUs deliver the same hash rate, power efficiency, or longevity under continuous load. Below, we explore the top graphics cards that have proven effective for cryptocurrency mining—balancing performance, availability, and cost.
AMD Radeon R9 295X2: Best Overall Mining GPU
The AMD Radeon R9 295X2 stands out as one of the most powerful dual-GPU cards ever released. Launched in April 2014, it continues to be revered in mining circles due to its exceptional hash rate of 46 MH/s to 57.6 MH/s—among the highest ever recorded for consumer-grade hardware. This makes it particularly effective for mining Ethereum and other Ethash-based cryptocurrencies.
However, this performance comes at a cost. The card consumes up to 500 watts under full load, significantly increasing electricity expenses. For sustainable mining operations, this power draw can erode profits unless you have access to low-cost energy.

Due to its age, brand-new units are nearly impossible to find. Most available cards on the market are second-hand, often previously used in intensive mining farms. While functional, these cards may have reduced lifespans due to thermal stress and prolonged operation.

NVIDIA GeForce GTX 1060 & GTX 1070: Best Available Mining Cards
For miners seeking reliable and still-accessible hardware, the NVIDIA GeForce GTX 1060 (6GB) and GTX 1070 (8GB) remain strong contenders.
The GTX 1070 delivers a hash rate of 27–36 MH/s when running EthOS or similar mining operating systems. With a TDP of just 150 watts, it offers a favorable balance between performance and energy consumption. Priced around $450–$490, it provides solid value for serious miners.
Meanwhile, the GTX 1060 (6GB) offers over 20 MH/s on the DaggerHashimoto algorithm used by Ethereum. It’s more power-efficient at 120 watts TDP and typically costs under $400, making it ideal for budget-conscious setups.
An interesting caveat: despite being newer and more powerful for gaming, the GTX 1080 performs worse for Ethereum mining than both the 1060 and 1070. This is due to its use of GDDR5X memory, which doesn’t align well with Ethereum’s base code optimized for GDDR5 latency characteristics.
These cards are more readily available than older models and continue to be popular in multi-GPU rigs.
AMD Radeon RX 570 & RX 580: Best Value for Mining
For beginners or those building cost-effective rigs, the Radeon RX 570 and RX 580 offer excellent value. The RX 570 (3GB) can be found for just over $150, while the RX 580 (6GB) typically sells for around $250.
When paired with Claymore’s Dual ETH Miner, the RX 580 achieves 26–29 MH/s, making it highly competitive for Ethereum mining. Its default TDP is 185 watts, but tools like AMD’s Radeon Wattman allow users to undervolt and reduce power draw below 150 watts, improving profitability.
A key tip: always choose models equipped with Samsung memory chips over Hynix. In memory-intensive algorithms like Ethash (Ethereum) or Equihash (Zcash), Samsung-based variants consistently outperform Hynix versions by a significant margin.
These cards are widely available and frequently used in entry-level mining farms due to their affordability and decent return on investment.

Specialized Mining GPUs from ASUS and Sapphire
In response to soaring demand from miners—often at the expense of gamers—manufacturers like ASUS and Sapphire have introduced mining-specific graphics cards designed solely for computational workloads.
ASUS Mining Series
ASUS launched the MINING-P106-6G and MINING-RX470-4G, built on NVIDIA’s GP106 Pascal architecture and AMD’s Polaris silicon, respectively. These cards lack standard display outputs (DVI, HDMI), as they’re intended for headless systems or setups using integrated graphics.
They feature robust cooling solutions with fans rated for 24/7 continuous operation, essential for long-term mining stability. Without the need for video output circuitry, these cards are often more affordable than their gaming equivalents.
Sapphire Mining Edition
Sapphire offers several RX 470 Mining Edition cards with VRAM options from 4GB to 8GB. Like ASUS models, they prioritize durability and efficiency over visual output. The newer RX 560 Pulse MINING Edition includes a single DVI-D port but no HDMI or DisplayPort support.
Other brands—including EVGA, MSI, Zotac, and Colorful—are expected to follow suit with similar dedicated mining hardware, signaling a growing market segment.
Are GPUs Still Viable for Cryptocurrency Mining?
While GPU mining was once a path to substantial profits, the landscape has changed dramatically. Increased network difficulty, rising electricity costs, and the shift of Ethereum to proof-of-stake (The Merge) have diminished returns for most home miners.
Today, GPU mining is less about profit and more about learning blockchain technology, participating in decentralized networks, or supporting smaller altcoins that still rely on proof-of-work.
For those in regions with cheap electricity—such as parts of Iceland, Canada, or China—it may still be marginally profitable. Otherwise, purchasing cryptocurrency directly from exchanges often yields better financial outcomes.
Frequently Asked Questions (FAQ)
Q: Can I still mine Ethereum with a GPU in 2025?
A: No. Ethereum completed its transition to proof-of-stake in 2022 (The Merge), eliminating GPU-based mining. However, some forks like Ethereum Classic (ETC) still support GPU mining.
Q: What determines a good mining GPU?
A: Key factors include hash rate, power consumption (watts), memory size (VRAM), and price. High hash rate with low power draw maximizes profitability.
Q: Is GPU mining profitable in 2025?
A: For most individuals, no. High electricity costs and competition from large-scale ASIC farms make it difficult to turn a profit unless you have access to very cheap power.
Q: Do I need multiple GPUs to start mining?
A: Not necessarily. You can start with one GPU, but profitability increases with scale—provided you have adequate power supply, cooling, and motherboard support.
Q: How do I monitor my mining performance?
A: Use software like MSI Afterburner, HWInfo, or built-in tools in mining OSes like EthOS or SimpleMining to track hash rate, temperature, and power usage.
Q: Are there risks to using GPUs for long-term mining?
A: Yes. Continuous operation at high loads can reduce GPU lifespan due to heat stress. Proper cooling and undervolting help mitigate these risks.
