Top Video Cards For Crypto Mining | Best Mining GPU 2023
Mar 06, 20236 min read
Although mining crypto is less profitable than in the past, it still can be for mining devotees. It's pretty expensive and non-ecological, database consuming. But still a way of earning crypto and providing the world with Bitcoin. Almost all blockchains have moved to the Proof-of-Stake model, but other top PoW coins still can be mined.
What Is a GPU?
GPU mining utilizes one or several GPU (graphics processing unit) cards for mining cryptocurrency. GPUs can process hashes much faster than CPUs, but ASIC is slower. GPU mining is typically reserved for mining altcoins due to the high mining difficulty of bitcoin.
GPU vs. CPU
Standard computers are equipped with a Central Processing Unit (CPU), an essential processing device for the whole computer system. It has control functions based on the logic of the operating system and the software installed on the computer. Typical functions—like saving the file, printing the spreadsheet, or running the video in VLC Media Player—are controlled by the CPU.
As for the GPU, the computer's part is responsible for its video rendering system and 3D graphics. It is in charge of graphics-intensive tasks such as video editing, gaming display, and decoding and rendering 3D videos and animations.
This division allows the CPU to perform high-level tasks for managing the whole computer while the GPU handles the video functions. A CPU helps you open a video file on your computer, but the GPU displays it properly once the file opens.
Why Is GPU Used For Mining?
GPUs are in demand because of their ability to mine cryptocurrencies. That happens because CPUs can only run one code in series, and GPUs can mine different segments of a cryptocurrency's blockchain simultaneously and collaboratively operate with different algorithms. How does it work? A specific software offers the same mathematical problem to both our GPU and the other miners connected to the network simultaneously; the first mining node to solve it gets a reward in the cryptocurrency being mined. The higher the hash rate (computational power) of the graphics card or a group of cards, the more chances it has to solve the mathematical problem (algorithm) and get the corresponding reward.
Tips to Choose GPU
What to consider when choosing a GPU? Here are some essential things to take into account before buying one.
The Hash rate of a GPU is a number of hashes per unit second, and that is the graphics card mining power extracted to write or verify blocks on the blockchain network.
Cost is even a crucial element to think about before making a purchase. In other words, you could evaluate the GPU's value by creating a cost comparison of various versions based on their primary attributes.
Electricity is the next critical factor in optimizing GNU mining profitability. Most GPUs are not for crypto mining and regularly consume excessive electric power rather than their hash rate.
In selecting the graphics card, the critical target might be mining a lot of cryptocurrencies as much as minimum electricity consumption.
The RAM's value for every version is another thing to remember. Mining cryptocurrencies like Ethereum (ETH), you might want not less than 3GB of RAM. Other cryptocurrencies, such as Zcash, might be mined for GPUs of less memory value.
AMD cards are affordable and productive but take a lot of electric power. Putting those elements into perfect consideration can make the mining operation in the long term.
Best Graphics Cards For Mining
There are two leading manufacturers of graphics cards — Nvidia and AMD. While choosing the brand and model, consider the return on investment (ROI). That's about time to recover the money you invested in the GPU. For counting this, use a mining calculator in the GPU. Here are some of them: Mining Profit Calculator and Probability Calculator.

Can You Use a Second-Hand GPU?
Worries about buying used graphics cards will show poor performance, and the GPU will fail sooner than expected. Generally, that's not the case. Mining GPUs doesn't have that dramatic level of reduction in capability. Why? Here are some reasons:
As a rule, experienced GPU miners cut off the power draw and underclock their GPU to make the graphics card more efficient. They only increase memory performance.
Contrasted to that, a gamer will want to overclock the GPU. That's quite risky.
Although miners run their graphics cards 24/7, this can also help minimize the heat-up/cool-down cycle that is stressful on silicon.
Thus, the major problem for GPUs is heat. There could be issues if the cards were used for mining in an exceedingly hot environment without proper airflow.
That's it — different types of mining need different hardware, and the best way to find the best hardware for your needs is to DYOR and ask some experienced miners for advice. Visit special chats and forums where crypto miners share their thoughts and experiences to listen to various points of view. Never hesitate to ask questions to those with more experience who can help you with advice.
