HiveOS — How to choose a GPU for mining

How to choose a GPU for mining

There are so many graphics cards available on the market that you can easily get lost. This article will help you choose the right GPU for mining Ethereum and other cryptocurrencies.

☝🏻Before we start

If you want to reduce the GPU power consumption and overclock your GPUs — uncover a wide range of GPU settings to reach their most optimal performance: clock speeds, core voltages, memory, and much more, try Hiveon OS to reach maximum efficiency in terms of hash/watt ratio.

Compared to last year, considering the shortage of video cards and the growth of the cryptocurrency rate, prices have significantly increased. But the profit from mining remains high and largely depends on the suitable device. You should consider a few things prior to the future acquisition. This step will help turn a video card into an effective cryptocurrency mining tool.

Note that the specified hashrates and power consumption levels are statistical averages — your results may vary.


If one owns a high-performance GPU that can handle high-intensity computer applications, this person can also use it for mining cryptocurrency. Choosing GPUs is the best solution for small-scale or individual miners. Moreover, when one chooses a GPU for mining, they get a lot of space for customization and flexibility and can mine different cryptocurrencies using multiple GPU rigs simultaneously; thus, the demand for GPU mining hardware solutions is increasing. So, nowadays, it is common for vendors to launch GPU mining hardware solutions specifically produced for mining (Technavio, 2020).

GPUs contributed 16.91% to the overall market in 2020 and should increase its contribution to 18.35% of the global cryptocurrency mining hardware market by 2025, according to Technavio. The source mentions that GPUs will have no competitors in the growing segment within the overall market. The forecast is shown in the chart below:

So, what criterias should you follow when choosing a graphics card for mining?

  • Price. Look for GPUs at the best possible prices. It will help your investment pay off faster. It is a great idea to estimate mining costs before purchasing a video card. It requires considering the actual price of the equipment, electricity costs in the region where it will be used, and the number of working hours per month.
  • Performance. If you plan to mine specific cryptocurrencies, check the expected graphics card's mining performance. A single high-end card can have the same performance as multiple low-end cards. This might mean you'll require more space, and they will probably generate more heat/noise.
  • Power consumption. Newer, more power-efficient cards will draw less power, but more power-hungry GPUs tend to be cheaper. If you have low electricity costs, you can afford to buy more power-hungry cards. Otherwise, look for GPUs with better power efficiency.
  • Resale value. If prices drop suddenly, gamers are more likely to buy newer GPUs with better gaming performance than the older ones.
  • Hashrate. It is a measurement that demonstrates a graphics card's mining power; in most cases, crypto mining farms are assembled according to this indicator.
  • Cooling system and RAM. It is essential to evaluate these criteria as the lifespan of the graphics card depends on the cooling system's reliability, and the speed of the RAM directly affects the speed at which the device makes a profit.
  • VRAM volume. Some cryptocurrencies like Ethereum Classic and Ergo will need at least 3GB of RAM for mining. In 2022, we recommend considering devices with a VRAM volume of 6 gigabytes or more, although mining methods on cards with 4 GB memory or less are still actively used.
  • The strain on the power grid. Keep in mind the strain on the power grid caused by high-powered graphics cards. This factor is often paid little attention to, though even a low-intensity mining process can damage a worn-out electrical system.

The latest RTX 3000 series cards offered an excellent performance to power consumption ratio. Unfortunately, because of shortages in the market, cards without LHR are tough to find. Despite this, the RTX 3060 Ti LHR offers excellent value for money in mining Ethereum and other cryptocurrencies such as Flux, Ravencoin, Vertcoin, Ergo, or Zeno.

To mine Ethereum at higher speeds, typically about 45 MH/s, use a miner that allows you to bypass the LHR lock partially. These include lolMiner, T-Rex, GMiner or NBMiner. Use the latest version of the miner to enjoy top performance. If you're using Hiveon OS, you'll be able to install any updates seamlessly with a single click from the dashboard panel via the website or mobile app.

The power to performance ratio when mining Ethereum is admittedly not a strong point of this card because of the LHR lock. Other cryptocurrencies like Ravencoin or Flux can be mined on it with full performance, though. So it's worth considering buying this card, especially if you plan on mining cryptocurrencies that are not limited by the LHR lock.

What is the future of GPU mining in 2022?

The future of mining in 2022 is in question. A possible Ethereum transition to Proof of Stake remains the biggest concern. The effective date for this change has been postponed several times; still, even if it is postponed once again this time around, the threat remains the ASICs entering the network, which could significantly increase the network's difficulty, meaning a decrease in revenue.

Can any GPU be used for mining?

Yes, almost any modern graphics card can mine cryptocurrencies. Ideally, it should have at least 5 GB of VRAM to mine Ethereum on it. Keep in mind that older cards are less energy-efficient; thus, the power costs may be higher than the revenue generated.

How to build a GPU mining farm?

You will primarily need graphics cards. Other components you will need are a power supply (or power supplies), motherboard, processor, risers, RAM (we recommend at least 4GB), mining frame, and a disk or flash drive. From the software part, choose a miner and an operating system.

How much would I make back if I spent around $1,200 on a mining rig with 6 GPUs (XFX Radeon RX 580 8GB)?

Revenues are affected by:

  • Cryptocurrency exchange rates
  • The difficulty of the network
  • Network traffic
  • System, miner, and mining pool

And costs are affected by:

  • Purchase price of graphics cards and accessories
  • Electricity price
  • Software prices
  • Taxes

Because of this, profitability is constantly changing, and it is tough to give an accurate answer.

How long will GPU mining last?

The most popular cryptocurrency currently being mined on graphics cards is Ethereum. Most miners choose it; still, once the Proof of Stake comes in (presently scheduled for June 2022), it will become impossible to mine Ethereum. Nevertheless, it will still be possible to mine other cryptocurrencies. However, it is predicted that the profitability of mining other cryptocurrencies will then decrease greatly because a significant part of the Ethereum network's hashrate will most likely shift to them.

Is mining Ethereum profitable in 2022?

During the last several years, Ethereum was organizing the transition to a Proof of Stake blockchain. Judging by multiple indicators, we can assume that the estimated period of the merge is the first half of 2022. As soon as Ethereum goes to Proof of Stake, it will be impossible to continue mining it. Consequently, the GPU miners will need to search for the other algorithms to switch to once the transition occurs.
