Best Graphics Card For Mining (Bitcoin, Ethereum, Dogecoin)

The heart and soul of any good mining machine depend on its powerful components. This is the reason why the best graphics processor for mining came into play. You’ll also want to buy with caution as its cost will affect how much money you earn from each coin mined with a significant margin.

The graphics card component takes care of all aspects of rendering images to the screen at its core. Graphics cards are often used for mining, but the first thing to consider is how many video output ports you have. If your graphics card only comes with a DVI port and does not have an HDMI or DisplayPort connector, be careful as this will prevent the monitor from connecting to the computer.

Graphics cards also need enough memory on board, so make sure you have at least 2GB of GDDR5 VRAM or more. It’s amazing how this GPU category will serve you at best with 24GB of RAM. Graphics cards are usually the most powerful component of a computer.

Mining is one such application that has been gaining popularity in recent years as it offers the opportunity to earn money with your equipment. To verify transactions on cryptocurrency networks such as Bitcoin or Ethereum, you must have a high-quality GPU on your side.

Support for the highest operating speeds thanks to the unique cooling design will ensure the smooth operation of the system. Cryptocurrency mining can slow down your system due to its demanding power. Another problem is electricity consumption. But thanks to the latest architects, you can easily speed up this procedure.

The Ethereum Mining Calculator and Profit Calculator

Before acquiring a Mining graphics card, you should have an overview of your possible income and ROI (return on investment). With the Ethereum Mining Calculator, these values ​​can be calculated taking into account the energy costs and possible pool charges. Since the development of the Mining Difficulty and the Ethereum Course cannot be predicted, this is always a snapshot. The mining calculator gives you a preliminary assessment and can better compare different graphics cards. We use the Ethereum mining calculator and the Coinwarz profit calculator.

In our Solo Mining and Pool Mining guide, we’re using two gigabytes of Radeon R9 290 graphics cards. Both graphics cards have been in use for over 2 years. They were used for Scrypt and Ethash based coins. But mostly for the extraction of Aether. Together, the two R9 290 graphics cards provide a hashing power of approximately 50 MH / s for Ether Mining.

We checked alternative graphics cards for you. As we have not tested graphics cards ourselves, the values ​​shown may differ.

How long can you mine Ether?

Please note that the final level of Ethereum (Serenity) ensures the transition from Proof of Work (PoW) to Proof of Stake (PoS). After that, Aether can no longer be mined. Unfortunately, there is no exact conversion date. An overview of the different stages of Ethereum’s development can be found here: Ethereum Milestones.


This summary is not a purchase recommendation. Before you buy, you should do your own research. As we did not test the cards ourselves, all information is without guarantee.

Various factors can affect mixing performance and the power requirement of a graphics card. These include, for example, selected parameters for ethminer or the CONF file. The Catalyst driver used may also affect the mixing performance. It is not recommended to use version 16.3 of the Catalyst driver as here the hashrate should be reduced by 30%. Many miners are still using version 15.12. But here too you have to look for the best possible result.

The GeForce RTX graphics card becomes a technological advancement. NVIDIA Turing enables them to offer unparalleled levels of graphical realism. For speed and performance, the EVGA GTX 3060 Ti XC Gaming comes with 8GB of GDDR6 memory.

NVIDIA GeForce RTX 3060 Ti GPU

NVIDIA’s GeForce RTX 3060 Ti isn’t the fastest graphics card in the company’s latest GPU family, but it offers a fantastic potential return on initial investment. It’s also pretty good at games!

There are several factors to consider when deciding which GPU to mine for cryptocurrency. Do you want to pay more up front now and potentially get higher profits? Or do you feel like mining will be a bit scattered with lower profits and you only want to spend a small amount on the GPU to earn a little more on the side?

The cryptocurrency market is financial in nature, which means it is extremely susceptible to media coverage and human emotions. Consider reports of environmental condemnation regarding Bitcoin that coincided with Chinese attacks to trigger a price spiral. If you’re going to spend 350,000 on a GPU to mine cryptocurrencies, it’s best to make sure you can at least recover your initial purchase cost.

That’s why we recommend not only the most powerful (and expensive) graphics cards available today. That doesn’t make sense in the current climate, but it’s also downright bad advice for those who are new to the wonderful world of digging digital currency. Unlike games where you only need the best GPU you can afford, picking one to mine for cryptocurrency is a bit more difficult.

AMD Radeon RX 5700 XT: Best runner-up GPU for crypto mining

Bottom line: It’s not just NVIDIA GPUs worth buying for cryptocurrency mining. AMD makes some excellent graphics cards such as the RX 5700 XT. While not as good as our top pick RTX 3060 Ti, this card will still be able to break through the 54MH / s hashrate with the same 8GB of GDDR6 VRAM.

Hashrate: 54MH / s | VRAM: 8 GB GDDR6 | TDP: 225W | Power input: 2x 8-pin PCIe

Producer Version Seller
AMD Radeon RX 5700 XT View on Amazon

  • Hashrate 54 MH / s
  • 8 GB of GGDR6 VRAM
  • 225W
  • great price
  • Efficient performance

AMD made a big leap with RDNA GPUs like the RX 5700 XT. It is based on a 7nm manufacturing process and makes even the company’s older Radeon cards look old and power hungry. While again the RX 5700 XT is not the newest and best from AMD, it is actually one of the best value propositions for cryptocurrency mining.

It’s good enough to play at 1440p, just like the RTX 3060 Ti, and it’s very good at mining. While AMD cards lose some of their gamer-focused features like DLSS 2.0 and the same level of ray tracing as NVIDIA GPUs, this is where mining is where that GPU really takes off. Its average hashrate is just over 55 MH / s, which is not far from the 3060 Ti, and these cards come at much lower prices.

If you want to start mining, the RX 5700 XT is worth considering.

Are you planning to invest in a new NVIDIA RTX 3080 GPU? Make sure your power supply is ready to snuff; if not, check out these top picks of the best power supplies.

Installing up the mining rig’s remaining 5 GPUs

GPU power from the power supply

Using one PCI-e 8-pin to 2x 6 + 2 cable to power two GPUs.

This is the part where things can get frustrating, hard to diagnose and wrong. Try not to get frustrated. We will go through this process. When we hear about issues, we’ll add a troubleshooting note under the section. To be clear, it is rarely possible to deposit all 5 cards without much tinkering, although it does.

  1. Make sure the mining platform is completely turned off, including turn off the main power on the power supply.
  2. Plug in and power up the GPU and Riser card for the open slot closest to the CPU
  3. Make a connection between the motherboard and the riser card
  4. Turn on the power adapter. Turn on the mining platform. Windows can be slow at logon as it wonders what has been added.
  5. Sign in and go to Device Manager> Display Adapters
  6. You should now have one more NVIDIA GeForce GTX 1070 card than it was listed on last boot.
    1. If it doesn’t appear immediately, wait a while while Windows finds it. Your screen may flicker or flicker and your mouse may be slow if Windows is still installing a new graphics card.

    Troubleshooting GPU Issues

    As we mentioned, this is the most frustrating part of building a mining rig. We just ask the hardware and software to set themselves up in a configuration that is not very common. And if everything is done in a slightly different order, or if Windows runs into an update that affects the process, things won’t go smoothly.

    There are a few things to check and do, usually in this order when the GPU doesn’t show up in Device Manager.

    GPU does not appear in Device Manager

    Never work with equipment with the mining platform turned on. Turn it off, turn off the AC adapter and disconnect it from the wall. We won’t repeat this over and over again with every troubleshooting step, but it’s necessary.

    • Turn off the mining platform and check that all connections of the faulty GPU are well matched. Disconnect each one and then reconnect them.
      • Check for an unknown device in the Other Devices list in Device Manager. If so, it could be a misidentification of your graphics card. Try reinstalling the unknown device driver.
      • The riser card is seated properly on the GPU
      • All the riser card connectors for the power supply fit snugly back into the power supply
      • The USB cable on the riser card and the connection to the small PCB that connects to the motherboard fit snugly
      • The 8-pin power that goes to the GPU is properly connected
      • The power cord at the power supply is properly connected to the power supply and all the way
      • Correct cable types are used for all power connections
      • No more than two GPUs are powered by a single power supply cable
      • No more than two powered risers are powered by a single AC adapter cable
      • After checking all these things, restart your computer and check if the video card now shows up in Device Manager. If it continues. If not, continue below.

      The Truth About Hardware Degradation

      More often than not, electronic components fail because of their basic mechanical hardware – and this should not be confused with electronics degradation. The fact is, computer parts don’t degrade linearly like mechanical parts. Sustained Mode shouldn’t use up your CPU unless you’re not properly maintaining your PC.

      Mechanical integrity is directly related to use. Old-fashioned friction is the main reason most hard drives, keyboards, and cooling fans have an expiration date. Proper maintenance will extend their service life for years, but eventually everything hurts.

      Fan Maintenance

      GPU mining itself is not a threat to your computer – it’s a run. Since most GPUs rely on inline or auxiliary fans, these parts can degrade more quickly over extended periods of use.

      To prevent damage to the card, you must clean it frequently. Make sure the blades are free of any debris that could cause excessive friction, and check periodically to make sure everything turns smoothly. When properly managed, prolonged computing activity such as mining cryptocurrencies and gaming should not degrade the physical integrity of the graphics card.

      Even with extreme caution, mechanical fans only make a finite number of revolutions before their material starts to erode. Fortunately, fans are one of the easiest parts to replace on a gaming PC.

      Then you need to connect the processor to the motherboard. Insert the selected processor into the socket of the motherboard. Be careful when removing it as thermal paste will stick to the CPU fan. Make a mark on both the motherboard socket and the side of the processor.

      GPU mining — beyond Bitcoin

      Getty Images

      While you can technically still mine Bitcoin with GPUs, Application Specific Integrated Circuits (ASICs) and Programmable Gate Arrays (FPGAs) can be specially constructed to compute specific hashing algorithms and are much more powerful and efficient than GPUs in bitcoin mining. The number of GPUs needed to match the “hash rate” of a single ASIC would prove expensive due to the enormous power requirements and associated costs.

      The Nvidia RTX 3090 Founders Edition has a hashing speed of 150 million hashs per second (150 MHps) and costs from $ 400,500 to $ 3,000. A popular ASIC like the Bitmain Antminer T17 + originally cost just over $ 800 and has a hash rate of 64 trillion hashs per second (THps). It uses much more power than the RTX 3090, about 10 times as much, but thanks to its much higher hash speed, it is a much better bitcoin mining hardware .

      That said, other cryptocurrencies can still provide valuable profit for GPU miners, including Monero, Ripple (XRP), and Dogecoin. A good way to determine which cryptocurrency to mine is to use a mining calculator. This usually allows you to enter the type of cryptocurrency you want to mine, the mining equipment being used or hashing speed, and the amount of energy you are using. From there you can see how much you’ll be able to earn.

      One of the more popular ways of solo mining is through software like NiceHash. This allows mining equipment to be borrowed for others to mine for alternative currencies. Profits are sent in the form of Bitcoin. The NiceHash setup process on your computer is fairly straightforward, and it’s perfect for those who don’t want to mess with the command line.

      That said, it might be worth trying to join a mining pool or take advantage of cloud mining. A mining pool combines the hardware capabilities of multiple miners to increase their computing power. Cloud mining can be a decent option for those who don’t have the money to invest in their own hardware (especially these days). With cloud mining, you rent mining equipment from companies like HashFlare to do the hard work for you. Then you get paid for your investment with Bitcoin.

      The GPU shortage continues

      There was a massive cryptocurrency boom that started around December 2020 as the prices of Bitcoin and Ehereum jumped drastically. This led to cryptocurrency miners quickly getting their hands on graphics cards, accounting for 25% of all GPU sales. Unfortunately, this contributed to the current GPU shortages and prompted Nvidia to limit the hash speed of newer 30 series cards.

      Despite the huge disadvantages of Bitcoin and Litecoin mining on graphics cards, the advantage is that graphics cards can still be sold on the secondary market due to their general use. ASICs, by definition, cannot be misused and therefore lose a lot of value if the specific algorithm for which they are programmed is not used.

      Additionally, if cryptocurrency prices collapse, it reduces the profitability of mining, which also reduces the demand for graphics cards and a large sale of mining GPUs that have lost profit, which can lead to an overabundance of GPUs in the secondary market, where prices in turn drop.
