As of March 2023, there was an increase in cryptocurrencies from 12,000 in 2022 to 22,900. These cryptocurrencies include Bitcoin (BTC), Ethereum (ETH), and altcoins such as USD coin (USDC), Binance USD (BUSD), and more. With this increase, many users seek the best GPU mining ways to profit from the crypto market. One popular method is buying and selling on exchange markets. Alternatively, you could become a miner if you don’t wish to trade cryptocurrencies.
Crypto mining is a way of acquiring cryptocurrencies by solving cryptographic equations. Successful mining operations add to the existing coin supply. Asides from gaining more coins, mining is an essential process to Bitcoin’s security. Mining cryptocurrencies can occur in several ways. CPU mining was the first mining method in Bitcoin’s early days. Mining became more complex, and Graphics Processing Units (GPUs) were rescued. The best GPU mining is inexpensive and more flexible than the third mining method with the Application-Specific Integrated Circuit (ASIC) hardware.
Not all computers suit crypto mining, as the process is quite intensive. To avoid system crashes, most users mine cryptocurrencies using GPU. While GPUs have different specifications and profitability, which can deliver a seamless mining process? This guide will show you the best GPUs to mine with.

Understanding Crypto Mining and The Role of GPU
What is Crypto Mining?
Crypto mining is a transactional process that involves cryptocurrency gaining by solving computational equations. Digital coin mining occurs on a blockchain architecture that supports PoW (Proof of Work). The blockchain serves as the public ledger for digital transactions. The two popular architectures are Proof of Work and Proof of Stake. Bitcoin and Ethereum used proof of work until September 2022, when Ethereum transitioned to proof of stake.
Proof of Work validates transactions by a network of miners. However, participants who place ether as collateral validate in proof of stake. Mining with PoW is competitive due to the high number of miners. PoW thereby consumes higher energy than Proof of Stake.
What is a Blockchain?
A blockchain records digital items, cryptocurrencies, and transactions at any time. It contains blocks of chained data, usually transactions that become a part of the ledger. Each blockchain user has an account that they only can access. When a transaction occurs, both parties have a private key that unlocks the encryption of their specific data. This way, transparent transactions can occur between users.
Blockchain is decentralized. Unlike the traditional banking system, which has all records in a central ledger, there is no major record for transactions. Simply put, your transaction does not need to pass through an authority before it can be completed. You may then ask, how are transactions verified and approved? Mining comes in. Blockchain uses cryptographic algorithms to verify transactions.
How Crypto Mining Works
You can liken the process of crypto mining to manual mining. While gold, silver, or diamond miners seek to find, crypto miners circulate new coins. Miners are tasked with solving complex equations in the form of cryptographic hashes.
A hash is a mathematical function that truncates an arbitrary length of data into an encrypted output of a fixed length. The mining process tasks miners to discover the hash function. The first miner to crack the code receives a reward in cryptocurrency.
A block, the smallest unit of a blockchain, is a store for transactions. The best GPU mining blocks have four main attributes:
- Data: An aggregate of transactions mined, validated, and arranged in the block.
- Previous hash: It stores the value of the hash of a previous block linking one block to another.
- Nonce: A random value that varies the output of a hash function. Each block is required to generate a hash value, and the nonce is the attribute that causes that hash value.
- Hash: the value obtained by passing the data, previous hash value, and the nonce through the mining algorithm.
These attributes form an unbroken chain of blocks that leads back to the first block. The link makes it easy for each user to quickly verify the blocks’ validity.
This procedure is used for mining Bitcoin and Ethereum mining. They have three primary purposes; adding new data blocks to the chain, leading to more circulation coins, and validating transactions to prevent fraud.
What is a GPU?
The initial intent of the GPU was for gamers to render graphics and 3D videos while playing computer games. However, it found a use in crypto mining in 2010. Technavio predicts GPU’s contribution to the global cryptocurrency mining hardware market will increase at a CAGR of 11.35% between 2022 and 2027.
Mining with GPU is a process that uses specialized graphics card cores to solve crypto equations. The best GPU for mining crypto will have properties that make them suitable for cryptocurrency mining. For instance, GPUs have many Arithmetic Logic Units (ALU), making them more efficient for mathematical computations. For this reason, miners prefer GPUs as they perform similar, repetitive, resource-intensive tasks faster with multiple cores.
Role of GPU in Crypto Mining
GPU mining decodes different hashes repeatedly and changes one digit in each attempt. The GPU can use different hashing algorithms to translate random-size data to a fixed-size hash. These algorithms shrink data to a smaller size to easily solve the different computational problems. They also keep data secure and verified. The common hash algorithms used by for the best GPU mining include:
The National Security Agency (NSA) and the National Institute of Standards and Technology (NIST) developed secure hash algorithm 256 (SHA-256). Its encrypted data output is always 256 bits long, which secures the transaction network from fraud. The best GPU for bitcoin mining utilizes this algorithm. With SHA-256, miners must convert the 256-bit hash into a 64-character output. The first miner to achieve this receives the reward.
Colin Percival, a Canadian computer security researcher, developed the Scrypt algorithm. It is faster and more efficient than the SHA-256. Encryption in Scrypt is a password-based key derived from different random numbers to prevent custom hardware attacks. The Scrypt has a record time of two and a half minutes for block generation, with the hash rate measured in kilo hashes (KH/s). It is used for Litecoin, Dogecoin, and Bismark.
Just as Bitcoin uses SHA-256, Ethereum, Ethereum Classic, and Expanse blockchains use Ethash making Ethereum mining ASIC-resistant. The Ethash algorithm was developed as an improvement on the previous Dagger-Hashimoto algorithm. One of the needs of Ethash is sufficient RAM, as it consumes large amounts of bandwidth. Mining is difficult as a result. Ethash measures the hash rate in megahashes (MH/s).
X11 uses eleven different hashing algorithms, as opposed to one by others. It was implemented in the Darkcoin protocol in 2014. Miners have the best GPU mining experience as it is an efficient mining algorithm. There is a top-level transactional security with X11. Also, it consumes less energy and computing power. X11 measures the hash rate in megahashes (MH/s)
GPUs require top hardware and software materials for the best crypto-mining gpu. One of GPU’s software is the Claymore Miner. Claymore software is specific to Ethereum. It is built with a dual Ethereum miner that allows two similar algorithms without altering the hash rate. Other software are the WildRig Multi Miner and KawPow Miner. While the WildRig Multi Miner software focuses on modern AMD GPUs, KawPow is incompatible with AMD GPU devices.
GPU vs CPU
Before GPUs, CPUs could mine cryptocurrencies. CPU mining uses a processor’s cores to validate crypto transactions and create new coins. However, they were less strong than GPUs. Miners now choose GPUs instead of CPUs because of the following:
A CPU has to perform its various tasks using sequential serial processing. On the other hand, GPUs break complex problems into multiple tasks and work them simultaneously. This significantly reduces the time it will take to perform these operations.
While a CPU usually has one ALU per core, GPU has as much as 1000 ALU per card. The more the ALU, the higher the hash rates, which subsequently increases its operational speed.
GPUs have more processing cores and higher memory bandwidth than CPUs. The best GPU mining hardware performs at a higher rate and efficiency. For example, NVIDIA GPUs can perform over 100 teraflops of computation beside the 1 teraflop performance of Intel CPUs.
GPU Mining Pools
You could mine cryptocurrencies as a solo miner, but you could also join GPU mining pools. GPU mining pools consist of groups of the best GPU miners who combine their computing resources to increase their chances of cracking cryptographic equations. When a mining pool succeeds, each miner receives a reward proportional to the resources contributed. Miners are not obliged to stay with a pool; they can change pools whenever needed.
Joining a mining pool has advantages, including more stable income, reduced earnings fluctuations, and a lower need for expensive hardware. It has disadvantages, including reduced total earnings due to reward sharing. There could also be the risk of central control by the pool operator, hidden fees, or transaction costs. While there are many crypto mining pools, joining official mining pools is best. Official mining pools roll out frequent upgrades, updates, and regular technical support.
Cloud mining is one of the best GPU mining methods that allows you to mine digital coins without owning mining hardware. With this method, you rent out another miner’s mining rig and receive a profit cut. On the other hand, you can rent your mining rig to other users, if you have one, to cut costs. That, however, comes with a reduced profit.
Factors to Consider When Choosing a GPU for Mining
Different GPUs may have similar or differing features. When buying a GPU, one thing to remember is productivity, efficiency, and longevity. What specific factors should you look out for?
The hash rate parameter tells the computational power used during crypto mining. It is the count of the number of hash operations per second. In crypto mining, the mathematical calculations used to generate coins are known as hash operations. The hash rate, also known as hashpower measures is measured in hash per second (H/s), kilo hash per second (KH/s), megahash per second (MH/s), gigahash per second (GH/s), or terahash per second (TH/s). The best GPU mining cards have measures starting from MH/s, as current hashrates are in billions of hashes per second. CPUs, on the other hand, measure hash rates in kilo hash per second (KH/s).
Generally, a miner with higher hash operations at a given period is likelier to solve the complex mathematical problem and earn the reward. The process is typical of the Proof of Work blockchain method. The mining difficulty of a particular cryptocurrency usually increases. When this occurs, miners need an equal computational power increase to maintain the same level of profitability. Simply put, miners need a higher hash rate to stay at the winning edge in the mining market.
The profitability of a GPU depends on the speed at which it executes operations. Each GPU has benefits and downsides in mining. While some will consume more power but with better profitability, others will have less power with delayed profitability. The best GPU mining hardware enables an increasing hash rate, which in turn increases your level of competitiveness and profitability.
Hashrate can also be a measure of the level of security of a blockchain. The information on the number of operations per second allows miners to judge a blockchain’s level of reliability and decentralization.
Crypto mining consumes a high power level, so it becomes necessary to consider the GPU’s power efficiency. In choosing the best GPU for mining, confirm that their power consumption aligns with your mining operation’s energy costs. Look for a GPU with a high hash rate while consuming less power. Such GPUs will help you increase profitability while minimizing operating costs.
The power efficiency measured in hash rate per watt, H/W, gives you an idea of the amount of hash rate a GPU can achieve per unit of power consumption.
Your energy costs include electricity costs. Recall that GPUs were not initially made for mining; some would consume excessive electric power rather than their hash rate. In addition to increased profitability, the best crypto mining GPUs consume low power, reducing heat output and increasing the GPU’s lifespan.
Price and Availability
GPU prices fluctuate considerably at different periods. It could be due to crypto prices, market demand, and production constraints. For example, high cryptocurrency demand can lead to shortages and inflated prices. So, when considering your options for the best GPU mining, check if the prices are within your budget and confirm their availability. You could also monitor market conditions to know when GPUs become available.
Sometimes, you may need to invest beyond your budget for better hash rates and power efficiency. Eventually, the investment will pay off in terms of profits. However, ensure that a high GPU’s cost correlates to high performance and energy efficiency before choosing.
Coin Mining Flexibility
The best GPU miners look out for coin mining flexibility before choosing a GPU. A good GPU should be able to mine different coins on different blockchain platforms. This flexibility places a GPU at higher profitability chances.
A typical example occurred when ETH moved from PoW to proof of stake (PoS) algorithms. Miners were able to mine other coins with GPUs easily.
VRAM (Video RAM)
GPU’s VRAM is essential for memory-intensive cryptocurrency mining. Since GPU carries out operations simultaneously, it requires a significant amount of VRAM to be effective in mining. Mining cryptocurrencies, like Ethereum, may require at most 3GB of RAM. Other cryptocurrencies, like Zcash, may require even lesser memory value GPUs. The evolution of cryptocurrency with new algorithms brings about varying VRAM requirements. VRAM serves as the buffer which stores data and intermediate results during the mining. The higher the VRAM, the higher the ability of a GPU to handle more complex mining algorithms efficiently.
Other factors to look out for include;
- Resale value: In choosing a GPU, ensure it will retain its great performance for a long time. This way, you can resell at a reasonable rate when prices drop.
- Cooling system: Evaluate the cooling system and ensure that it is durable throughout the lifespan of the GPU. The best GPU mining hardware experiences overheating less frequently.
Consider all these factors before making a long-term GPU purchase decision.
