Best CPU for Mining 2021: Best CPUs for Mining Cryptocurrency – Probably every person who studies the topic of mining has thought about how profitable is the mining of cryptocurrencies using a processor. After all, the most popular coins are now obtained using video cards or special devices.
Processor mining is available to almost every personal computer owner. However, due to the ever-increasing complexity of the network of popular cryptocurrencies such as Bitcoin , Ethereum , Litecoin and so on, their mining on the processor has become unprofitable.
But this does not mean that it is absolutely impossible to make money on this type of mining. In this article, we will talk about the current processors for mining cryptocurrency, profitability and talk about the profitability of this type of receiving tokens.
What is processor mining
What-is-processor-mining
CPU mining is the process of mining a cryptocurrency by finding a hash using the computing power of a central processing unit (CPU) and assigning it to a block within the cryptocurrency blockchain.
For the first time, mining was launched on the central processor by the creator of bitcoin Satoshi Nakamoto .☝️It was with the help of the central processor that Satoshi mined his 1 million BTC.
At the dawn of the era of cryptocurrencies, when bitcoin was worth a few cents, mining even on a very average central processor was very efficient, the only thing is that the bitcoin price of a few cents then compensated for this phenomenon.
Mining on a processor is theoretically possible with cryptocurrencies that support the following algorithms :
- SHA-256;
- X11;
- Ethash;
- Scrypt;
- Equihash.
In theory, because in practice, in the future, with the development of the cryptocurrency industry, the baton of mining was first taken over by video cards , and after ASIC miners (Application Specific Integrated Circuit) – by specialized high-performance devices. The computing powe that they provided left both central processors and video cards out of the game (with the exception of mining those cryptocurrencies that run on Ethash or Zhash algorithms).☝️At the moment, mining on a processor is unprofitable due to the high complexity of the network and the use of ASICs.
Mining on server processors
A server processor is a more efficient and stable modification of a conventional central processor designed to work in data centers and with a high network load.
How is a server processor different from a regular processor? In fact, a server processor has several differences from a regular desktop processor:It is designed for continuous operation 24/7 and under maximum load. For this, all instances of the server processor undergo extensive testing under extremely stressful conditions for operational stability and compliance with the requirements for this type of equipment. Their planned term of operation is 5 years, in constant load mode, while the planned term of operation for the desktop processor is only 3 years, and at the same time with less load.Server processors have more cores than desktop processors. So, in standard desktop processors, up to 8 cores can be installed, while in server rooms the average number of cores is 12.Support for large arrays of RAM, so even outdated models of server processors supported up to 144 GB.
Another difference between the server modification and the desktop modification lies in a different operating principle. The server processor is designed to work with a powerful stream of network data, in fact, in relative single-tasking mode, while the desktop version works in multithreading mode with many small tasks. Also, server processors for mining are characterized by support for ECC, noise-immune memory both in the internal cache of the processor of all levels and in RAM.
Mining on server processors also has a slightly higher efficiency compared to mining cryptocurrency on a conventional processor, including due to the larger amount of L2 cache in the server modification. But this only works with the appropriate support for AES instructions in the server processor model.
The server processor is good for mining cryptocurrencies , due to its greater reliability and performance, but only in comparison with a regular desktop processor, but video cards and ASICs still bypass it in performance.
In addition, it should be understood that the server processor consumes more power and is much more expensive than the desktop one.
All cryptocurrencies supporting the CryptoNote and CryptoNight encryption algorithms can be mined on the server processor .
How to mine on a processor
To start mining on a processor, you need to do the following (for example, mining Monero):
- Download the program for mining.
- Get a wallet for storing mined coins.
- Choose a suitable mining pool and register in it.
- To start mining on the processor, you need to create a file with the BAT extension (this is a regular file with the TXT extension, in which you need to change the extension to BAT).
- For example, we took the nanopool pool . Therefore, the following should be written in the file: NsCpuCNMiner64.exe -o stratum + tcp: //xmr-eu1.nanopool.org: 14444-u Your Monero address -px -pow7 1 -t 2, where 2 is the number of threads for mining Monero.
- We save the file and run.
- Mining has started.
Note that the number of threads should be selected based on the capabilities of your processor. Each thread requires about 2 MB of cache. For example, on Intel CPU i7-7700K, the total amount of cache memory is 8 MB. Accordingly, it makes no sense to run more than 4 threads if you plan to use your computer not only for mining, but also for normal use.
Mining on a Xeon processor
The Intel Xeon processor family is a server line of powerful CPU models known for reliability and performance.
In some cases, mining on Intel Xeon server processors is significantly ahead of the same activity on the Intel i7 and i9 desktop processor family. So, the server model Intel Xeon E5-2650 demonstrates a decent result for the CPU at 143 kH / s, while the desktop model Intel Core i7-3960X shows only 101 kH / s.
For comparison: the Nvidia GeForce RTX 2080 Ti video card demonstrates a result of 52.5 Mh / s.
Setting up a mining procedure on a server central processor is no different from setting up a desktop model. You need to launch the program’s graphical interface, specify the necessary data there and start the mining process.
How to choose a processor for mining
Choosing a processor for mining, we are faced with two companies – AMD and Intel. And considering that the “red” ones have recently been releasing multi-threaded processors, they are the best choice for mining. But let’s take a look at the CPUs from both companies:
* Processor prices were taken based on Yandex.Market data
** Let’s clarify that although AMD claims improved performance of the new line, in fact, it produces the same power when mining. And in the case of some algorithms, it is worse than previous models.
*** The presented profitability and payback are calculated without taking into account the cost of electricity.
**** Payback periods, like profitability, depend on the rate of cryptocurrencies and USD.
It should also be borne in mind that new processors from Intel, the cost of which is significantly higher than 20,000 rubles, is not recommended for mining. First, the payback period is much more than two years. Secondly, all this time the processor must work, which means that there is a high risk of breakdown.
And if you consider that in addition to the processor, you need the same powerful motherboard and cooling system, the new equipment will not pay off for sure.☝️Enthusiasts who are still mining on processors prefer to buy used equipment. In this case, it pays for itself about a year.
If we talk about server processors, then mining on them is profitable only if they support encryption based on the AES (Advanced Encryption Standard) algorithm. For example, even a new CPU that does not have built-in AES will have lower performance than an old Pentium or Intel i3, but with support for this function.
How to choose a processor for mining cryptocurrencies in 2021 is described in detail in the video below (since 2020, the trends have not changed):https://www.youtube.com/embed/JZi3e_dG-18Mining on the processor 2021
Calculating the profitability of mining on the processor
Calculators for mining on a processor provide information with a detailed calculation of the profitability of mining cryptocurrencies. As a rule, these are the same online platforms that calculate the cost of mining for video cards and ASICs. Based on certain algorithms and cryptocurrency quotes, these services calculate the profitability of mining in real time, that is, at the current rate of the cryptocurrency .
The services are arranged according to a simple principle: you enter the name of the model of the central processor, the cost of electricity in your region and get a calculation for the required cryptocurrencies, usually with detailed information about which of them is the most profitable at a given time period.
A list of the most convenient calculators for mining on a processor is below.
NiceHash
Link to calculator NiceHash
An excellent mining calculator that initially provides calculations for the associated cloud mining service and marketplace with remote mining power trading. Simple, straightforward and convenient. The service supports as many as 24 algorithms.
As an example of using a mining calculator, we will calculate mining on two different central processors, two desktop ones from Intel and AMD and one server one using NiceHash calculator.
We will take the best high performance models for the most up-to-date picture possible.
First example: AMD’s top central processor – AMD CPU Threadripper 1900X.
As we can see, mining even on a very powerful processor, if it provides profitability , is very relative, especially against the background of the same indicators from video cards and ASICs.
Second example: a central processor from Intel – Intel CPU i9-9980XE:
The screenshot shows that in the case of even such a powerful processor, mining on central processors – if it has a profitability, it is very relative.

How to choose a program for mining on a processor
Programs for mining on the processor act as an intermediary between the user’s equipment, the mining pool and the blockchain of the selected cryptocurrency.
It is worth choosing time-tested mining programs and downloading them only from an official resource, since third-party sources can provide the user with infected software for hidden mining .
Reliable programs for mining on the central processor are described below.
Claymore’s CryptoNote Windows CPU Miner
An excellent mining client powered by the CryptoNote algorithm with a wide range of customization and no developer fees. The program provides all the possibilities for mining on the central processor for both desktop and server modifications.
Download Link Claymore’s CryptoNote Windows CPU Miner
XMRig miner
This mining client provides standard options for setting up mining on the central processor. The program takes a commission of 5% from users by default, but if you set the donation level to 1, then the user’s commission to the developer will be 1%.
For successful work, you must provide the program with administrator access. XMRig miner also allows you to customize the number of threads for the CPU, which allows you to fine-tune your mining.
However, it should be taken into account that each thread requires 2 MB of L2 cache, so not all mid-range processors such as Intel CPU i7-7700K will support the mode with more than 4 threads. XMRig miner download link
Mining on a processor and on video cards – the differences
Probably one of the main differences between mining cryptocurrencies on a processor and video cards is too little profit or no profit at all. But at the same time, CPU mining is more affordable, since even average personal computers have a relatively good processor.
The CPU is responsible for the software tasks that control all the components of a personal computer, laptop, or any other device. The processor, to some extent, manages all the components, makes decisions and issues commands to programs.
The GPU, in turn, is responsible for processing graphics and displaying images on a monitor connected to a personal computer or other equipment. Unlike the CPU, the video card does not issue any commands, but, on the contrary, executes them.
At the same time, video cards use a faster type of memory compared to processors, which in the context of mining means high bandwidth for parallel computing.☝️The CPU can run one or two threads per core, while the GPU bandwidth is in the thousands per multiprocessor.
It turns out that even from a technical point of view, the difference between a processor and a video card is huge. And when it comes to mining, performance plays an important role.
What cryptocurrencies are profitable to mine on a processor in 2021
In 2020, mining cryptocurrency on a central processor is practically unprofitable due to the takeover of the mining industry by more productive ASICs and video cards for mining .
Is it possible to mine on the Bitcoin processor?
Mining Bitcoin (BTC) cryptocurrency on a central processor is unprofitable due to the high complexity of the network and the work of a huge number of ASICs in it. An article on how to mine Bitcoin correctly and profitably
Is it worth mining Ethereum on a processor
Cryptocurrency Ethereum (ETH), as one of the most popular coins, is of great interest to miners, but like bitcoin, due to the high complexity of the network, it is unprofitable if it is mined on a central processor. An article on how to mine Ethereum correctly and profitably
How to mine Monero on a processHow to mine Monero on a processoror
The anonymous cryptocurrency Monero (XMR) is also popular with miners, but unlike the first two, it can be mined on a central processor. Monero can be successfully mined on a CPU if the miner owns powerful processors of the Intel CPU i7-9750H or Intel CPU i9-9980XE level, and better in a sufficiently large quantity.☝️Also, do not forget about the need to connect your system to the mining pool, in solo mode, mining monero will simply be unprofitable
The profitability of mining Dogecoin on a processor
The Dogecoin (DOGE) cryptocurrency meme can be mined until 2021, if the user has several central processors of the Intel CPU i9-9980XE level and is connected to the mining pool.
However, in 2021, due to the high level of hype around the Dogecoin cryptocurrency, mining it with a processor is unprofitable. ☝️Read the full article: Dogecoin mining: is it profitable to do it?
Is it possible to mine Zcash on a processor
Another anonymous cryptocurrency, Zcash (ZEC) , is often used by hackers, but since it is accepted on a number of major cryptocurrency exchanges, it is also interesting for miners. However, its network complexity and market value is such that it is simply unprofitable to mine it on a central processor.
Pros and cons of CPU mining
Pros:On a powerful processor that allows you to both mine cryptocurrency and work in parallel, you can have a small passive income.You can try to mine a not very popular coin, but in larger quantities than the popular one. And if she ever “shoots”, there is a chance to make a good profit.
Minuses:To get at least some profit, you need a really good processor and preferably a multi-threaded one;In the case of expensive electricity, mining on most processors becomes unprofitable;Even if you purchased the most expensive and top-end processor, mining such coins as Bitcoin, Ethereum, Litecoin and other popular tokens will be unprofitable;Keeping track of the CPU is even better than the GPU farm. And if the processor burns out, the likelihood of the death of the motherboard is high. All this will cost a pretty penny.
What is better to mine on: Processor in 2021
In 2020, mining on the central processor, mining of any known cryptocurrency will be either unprofitable or cost-effective on the verge.
But as an option, it is possible to mine little-known cryptocurrencies, with their subsequent storage in the hope of selling them during the pump on the cryptocurrency exchange. However, it should be understood that some cryptocurrencies may remain in your wallet without the ability to exchange them for fiat money . This is due to both the lack of demand for such cryptocurrencies and the reluctance of cryptocurrency exchanges to list such coins.
It is also worth saying that mining on a processor in 2020 is possible, but compared to video cards, and even more so with ASICs, it brings very little profit. Even the most powerful processor is inferior to the GPU.
Depending on the number of cores, one processor core can process four 32-bit instructions per clock cycle (SSE) or eight 32-bit instructions per clock cycle (AVX). In turn, the video card is capable of processing 3200 32-bit instructions per clock. Thus, the performance of a GPU is hundreds of times higher than that of a CPU.
Also, most blockchains use mechanisms for adapting computational complexity so that the time to find each block is constant. That is why, with the increase in computing power in the network, the difficulty of finding blocks also increases.
In this regard, there are only a few cryptocurrencies, the mining of which on the CPU to bring at least some income. Such coins are optimized for mining on processors, which is associated with an increased level of network security.
To a greater extent, these include coins operating on the CryptoNote scheme and CryptoNight algorithms (CryptoNightV7, CryptoNightV8, CryptoNightR, CryptoNightHeavy and others).☝️The most proven and well-known coin using these algorithms is the Monero cryptocurrency.
Other algorithms on which it is theoretically possible to mine cryptocurrency using the CPU:
- SHA-256 (little-known bitcoin forks );
- X11 ( Dash , Pura and others);
- Ethash (Ethereum, Ethereum Classic and other ERC-20 coins );
- Scrypt (Litecoin, Dogecoin and others);
- Equihash ( Zcash ).
Attention! The complexity of the network of coins such as Bitcoin, Litecoin, Ethereum and even Zcash has grown so much by 20202 that it practically does not allow for profit from mining on processors.
Prospects for mining on the processor in 2021
To be honest, it is not impossible to call mining on a processor promising in 2020, but it is very difficult. Yes, when the cryptocurrency industry was just beginning its development, even Bitcoin was easily mined on the CPU.
But with the development, this type of mining has almost completely lost its relevance. Especially with the advent of ASIC miners and FPGA devices. In fact, they completely survive not only the mining of cryptocurrency on processors, but also video cards.
Of course, it makes sense to mine new coins, the complexity of the network of which is not yet as high as that of popular tokens, and the competition among miners is low. However, there is a risk of stumbling upon a scam or simply facing difficulties in selling the mined cryptocurrency.
And if you choose a non-popular coin, then you should take into account whether it will be popular in the future or whether it will remain among the noname projects. And if the exchange rate does not grow even in the long term, then there is no point in such production.☝️Therefore, if you are interested in exceptional income in mining, then mining on a processor is unlikely to be suitable.
In this case, it is worth considering more profitable options, such as buying an ASIC miner or building a farm on a GPU. Indeed, every year the complexity of networks will only increase, which means that the requirements for equipment capacity will grow.
Best CPU for Mining 2021: Best CPUs for Mining Cryptocurrency
Looking for the best mining processor for your next rig? It’s worth knowing that over the past couple of years, cryptocurrencies like Bitcoin have peaked and dropped. With the recent resurgence of Bitcoin, competition for cryptocurrency mining continued to intensify to the point that today it is becoming a constant challenge for ordinary computer users to find coins. A profitable way.
As a result, mining rigs remain in short supply and replenishment slowly, and serious miners had to expand material farms in order to continue working. There are business cycles, however, including cryptocurrency mining, and while conditions may make it difficult to mine profitable mining, this is a dynamic situation that is currently undergoing a renaissance.
New Miners Should Remember Keep in mind that most cryptocurrency mines rely heavily on the processing power of the GPU. However, some protocols can take advantage of the modern processing power of the processor. Also, some coins like Bytecoin and Zcash are better suited for CPU mining than more standard coins like Bitcoin or Ethereum.
With this in mind, hardy miners and dedicated enthusiasts should still invest in cryptocurrency mining hardware. Combine the best mining processor, the best mining GPU and the best mining motherboard and choose the best cryptocurrency for your needs, and you can quickly have a mining plant that can potentially start earning enough to recoup your hardware and power consumption while still getting profit.
So, my mining processors will hit the market in 2021.
