10 Best Mining CPUs for 2023

Mining is the process of creating new coins and validating new transactions. Anytime someone spends crypto currency, the blockchain ledger must be updated. Unfortunately, digital platforms are simple to manipulate, so only verified miners can update transactions on the public blockchain using a currency’s distributed ledger. Because of this, miners now have the additional duty of protecting the network against double-spending. This method is known as proof-of-work.

There are different types of mining, such as CPU, GPU and Asics. CPU mining works by using the CPU to solve mathematical equations to create transactions on the blockchain. Still, with the blockchain growing so large, miners usually join a mining pool that combines the computational power of every CPU in the pool. The mining pool solves equations faster, and pool members share the reward.

What To Consider When Buying a CPU for Crypto Mining?

The factors to consider before buying a CPU for mining include.

A mining experience improves with additional processor cores. An eight-core CPU can make the mining process twice as efficient. This is so that the blockchain algorithms can use each CPU core separately.

One of the most significant drawbacks of crypto mining is that mining requires a lot of CPU power, which wastes energy. Finding a CPU with reduced power usage will undoubtedly result in significant long-term cost savings.

Faster clock rates translate into faster hash rates and more money when mining cryptocurrencies. When selecting a processor for mining, look for high GHz values.

A thread splits the number of cores in a process, doubling and causing the cores to run smoother and faster. A processor typically threads twice the base amount of cores, so a four-core processor will produce an average of eight threads, while an eight-core will produce 16 threads.

What Is the Working Logic of CPUs for Mining?

an image with miner digging with graphic card

What is mining? Crypto mining is a way of generating new coins and a way to validate crypto transactions. Miners compete to be the first to complete challenging mathematical puzzles once a transaction block has been filled. This is where the CPU comes in, as powerful computers are needed to solve the equations. A more powerful CPU can solve equations faster, resulting in more rewards for the miner. Once the equation is solved, a 64-character hash is produced, validating the transaction and allowing the miners to create Bitcoin, Ethereum or whatever coin is being mined.

Is a CPU Enough for Mining?

an image with CPU processor

No, a CPU is just one of the items needed to build a mining rig. Other components required to mine include a hard disk, motherboard, graphics card, RAM and a power supply unit.

The mining setup performs better when there’s sufficient storage space. Users mining with a mining pool; can get a hard drive of at least 120GB SSD, but anyone mining independently needs to consider the blockchain size and how fast the volume grows.

The motherboard connects every component on a mining rig, allowing each piece to communicate with one another. The best motherboards can support up to six GPUs for those setting up a GPU mining rig.

an image with CPU icon

The graphics card or GPU is essential for mining. Several altcoins such as monero and electroneum can be mined with just a CPU. However, to mine ETH, a graphics card is required. When buying a GPU, consider the hash rate (which measures how many calculations can be done per second. A higher hash rate means more mining power) and the energy consumption. Graphics cards today are costly, so always check the best GPUs for mining to get the power consumption and hash rate before buying.


RAM requirements are not so high for mining. RAM is only necessary for the machine to boot and remain operational while mining. RAM does not significantly impact mining performance.

The final component of a rig is the power unit. Different types of PSUs are on the market, which can make buying a power supply unit a confusing task. Calculating the power needed by each component and selecting a PSU that can deliver more energy than the total amount necessary for all parts to work is an excellent rule to follow when choosing the best PSU.

How Much Energy Does the CPU Consume for Mining?

The amount of energy consumed by the CPU mining setup depends on the CPU. The manufacturer usually lists the CPU’s energy consumption, so check the packaging. The energy consumption is measured in watts (W). Other factors affecting energy consumption include the number of cores, clock frequency or clock speed and heat generated.

an image with bird view of electricity energy for mining

Clock frequency or clock speed is the number of cycles a CPU can complete per second, expressed in GHz. The clock speed establishes the rate at which a CPU can process a sequence of instructions at any particular moment. The higher the clock speed, the more power is consumed. CPU power consumption increases as the square of the clock speed. For the most optimal mining performance, the CPU needs to be run at the lowest clock speeds that still get the job done in the fastest time possible.

The core is the internal processor of the CPU. The core interprets and executes the user’s instructions. All current CPUs have many cores, and each core can perform a separate task simultaneously. This implies that a CPU with more cores can process more instructions. Hence, the more cores a CPU has, the more energy-efficient.

Pro Tip:

When a CPU overheats, the CPU will require more power to carry out the same tasks. So always keep the CPU mining as cool as possible.

Does Mining Increase the CPU Temperature?

Mining is a power-intensive process, and as the mining process continues, the CPU consumes more power, raising the temperature and leading to overheating. GPUs usually come with two to three fans and a heat sink to stay cool, but CPUs don’t. To get the best out of the CPU, ensure the temperature stays below 80 degrees celsius.

an image with CPU processor overheated

If the temperature exceeds 80, the CPU is at unsafe temperatures, leading to short-term failures and long-term permanent damage.

Use the best CPU temperature monitor software to ensure the temperature is safe.

How Much Can You Save per Day With CPU Mining?

CPU mining can be profitable, but several factors influence profitability. The most important factor influencing profitability is the coin being mined. The best way to make money from mining is to look for coins with a low hash rate.

Should You Pay Taxes for Crypto Mining?

Yes, miners are required to pay taxes for crypto mining. Ethereum, bitcoin and other proof of work cryptocurrencies are taxed in two ways. Tokens received for performing mining activities are taxed under regular income. The tokens are subject to additional taxes, depending on whether the individual is mining as a business or a hobby.

Another taxable event is triggered when the miner sells the tokens for profit (fiat). How much the token price changed since the minting day determines the amount of capital gains or losses. The best crypto tax software can calculate a reasonable price for each coin mined depending on the time and date the user deposited the token to a wallet.
