Review of cryptocurrency mining rigs: CPU ،GPU up to ASIC

Cryptocurrency mining rigs come in different forms (including CPU, GPU, ASIC, FPGA and cloud mining). which offer varying degrees of hash power and mining rewards.

Cryptocurrency mining on the blockchain platform is a way to help secure the blockchain network against attacks. Meanwhile, miners are encouraged to cooperate in securing the blockchain by receiving rewards. Click to understand more about this article.

Mining setups – colloquially known as rigs – can vary in price, size, scale, performance and efficiency. For example, a mining rig can be a central processing unit (CPU), graphics processing unit (GPU), digital programmable chip (FPGA), or application-specific integrated circuit (ASIC).

Some of the most important factors when setting up mining are: Price, power consumption, compatibility and hash rate. (Hash rate or hash power is a measure to measure the performance of a miner’s device. In other words, hash rate shows the speed with which a miner succeeds in solving the hash in order to receive a reward). Below are some of the pros and cons of different crypto miners.

Mining rig in different types, shapes and sizes:

Cryptocurrency mining is a way to help secure the blockchain network from attacks as well as financially incentivize miners to help secure it. Cryptocurrency miner, mining rig, bitcoin miner, mining hardware, these are just some names of circuits, processors and computer hardware used to mine digital currencies.

Some mining rigs are made for a specific purpose. General purpose rigs (much like your personal computer) can enable you to participate in cryptocurrency mining. Cryptocurrency miners are used in blockchains that follow the Proof of Work (PoW) algorithm. PoW is a consensus mechanism used to securely process and verify transactions that prevent double spending and other attacks on the blockchain.

Blockchains with PoW mechanism:

The most well-known blockchain with PoW mechanism is Bitcoin. Although other established networks such as Ethereum 1.0 also fall into this category. In this article, we will explore different tools for mining cryptocurrencies: from using general-purpose circuits to custom mining hardware.

Cryptocurrency miners usually focus on two things above all else: Hash rate and energy consumption. Hash rate is measured in hashes per second (h/s) and is related to the probability of solving cryptographic equations to obtain a block or mining reward.

Miners also tend to pay attention to the power consumption of mining rigs, including their overall energy consumption and efficiency in terms of hashes per kWh. Without sufficient hash power and energy efficiency, a miner will not be profitable. And it may actually cost you more electricity than any mining reward you get in return.

While some miners perform the mining process solely to support network security and the broader mission of decentralized networks. Most cryptocurrency miners are used to make a profit.

1. Is mining with CPU still suitable?

The process of mining digital currency with CPU uses a central processing unit called (CPU). CPUs can be found in everyday hardware such as laptops and computers (PCs).

In the early days of Bitcoin (BTC) mining, BTC miners were successfully mining blocks with their laptop and desktop processors. This was possible because there were very few miners at the time and thus the overall hash rate was much lower when the Bitcoin network was in its infancy.

And as a result, less competition means a higher mining success rate. As Bitcoin grew in popularity, so did competition, making it largely obsolete and difficult to mine Bitcoin with available CPUs.

Which blockchains are suitable for CPU mining?

There are also some blockchains that are designed to be suitable for CPU mining. Including Bytecoin, Zcash and Monero. The main reason for this type of design is to allow ordinary miners to profitably compete with large-scale institutional miners who have mastered mining on other major blockchains.

Besides being fairer, this also ensures that such projects maintain the decentralization of mining. As mentioned, CPU mining has been suitable for mining Bitcoin and many PoW blockchains in the past.

At larger mining volumes, CPU miners cannot use electricity as efficiently and their hashing power cannot compete with other mining tools.

Mining with CPU chips is measured in kilohashes per second (kh/s), where each kh is equal to 1000 hashes. Mostly, the best CPUs achieve 8-20 kh/s, and only a few (by 2021) exceed the 20 kh/s threshold. These numbers in

Compared to the power of other types of mining rigs, it is very low.

2. GPU mining takes over:

With the increase in interest in cryptocurrency mining, the number of miners and thus the competition for mining rewards has also increased. As a result of this cycle, most high-value cryptocurrency miners have stopped using CPUs and started using GPUs.

Because these systems are more efficient for mining and have a much better hash rate than CPUs. The first software for GPU mining was released in 2010. While CPU hash rate is measured in kh/s, GPU hash rate is measured in megahashes per second (mh/s). Each 1000 kilohash is equal to one megahash (one million hashes).

GPU performance varies based on age and price. But many modern GPUs do more than 10 mh/s. The performance of some of the best GPUs also reaches 60 mh/s (as of 2021). Having said that, a GPU miner with a speed of 40 ms/s has 2000 times more hash power than a CPU miner with a speed of 20 k/s.

Why GPU miners became popular?

GPU miners have access to these benchmarks. Because they can process many more operations in parallel with a single CPU. In addition, many miners form mining rigs. Each of which has 6 to 12 GPUs, which multiplies their hashing power.

Some crypto mining enthusiasts have multiple mining rigs running with multiple GPUs. Or even in some cases, 24 to 48 GPU rigs are active simultaneously. In addition to being much faster and more efficient than CPUs, GPUs also have a certain flexibility. So that they can mine all kinds of coins with different mining algorithms in different blockchains.

There are many coins available for GPU mining and Ether (ETH) is one of the most popular in 2021. However, with Ethereum moving to Proof of Stake (PoS), these miners may be forced to substitute another currency.

While GPU mining of Bitcoin quickly replaced CPU mining, its mining dominance was relatively short-lived. Until 2015, when Bitcoin mining was dominated by a new type of hardware called ASIC miners.

3. Now ASIC miners take over Bitcoin:

ASIC miners, which stand for “special purpose integrated circuits”, are designed to do only one thing, and that is to mine digital currency.

The first ASIC miner was built in 2012 and was about 200 times more powerful than standard GPU miners at the time. GPU computing power is measured in mh/s. While ASIC mining power is usually measured in terahershes per second (th/s), one terahertz is equal to 1000 megahash (one trillion hashes).

As of 2021, top ASIC miners can calculate 90-100 th/s, which is much higher than GPU miners. However, ASIC miners also have weaknesses that have prevented them from dominating the entire cryptocurrency mining sector. Asic miners are expensive and their prices usually range from $2,000 to $15,000.

This is a significant expense and it will take some time until its costs are even with its income. This is a significant expense and it will take some time until its costs are even with its income.

Advantages and disadvantages of ASIC mining rigs:

With different scales, power costs and network issues, buying ASIC miners can be both very profitable and very expensive. In fact, a large number of ASIC mining operations must be performed to compete. (with warehouses filled with hundreds or thousands of ASICs).

Moreover, even the fluctuations of the digital currency market itself can affect the profitability of mining. Because these mined coins can fluctuate significantly in price. Therefore, they affect the profitability of mining rigs and expensive ASIC warehouses.

However, ASIC miner manufacturers have released them for Litecoin (LTC) and other blockchains that use the same algorithm as Script.

4. Are FPGA miners one of the best mining rigs?

FPGA miners, short for programmable block, are often faster and more efficient than GPUs for most mining algorithms. while retaining the ability to reconfigure to mine a wide variety of coins. (which most ASIC miners cannot do).

For this reason, some miners consider FPGA setup to be the best option for mining. Because FPGAs can combine strong hashing power with the flexibility to mine multiple types of coins or different algorithms.

Because FPGAs can combine strong hashing power with the flexibility to mine multiple types of coins or different algorithms. Because they can be programmed or changed “on a case-by-case basis” after delivery to the customer. “The word G stands for Gate” refers to logic gates. which can be programmed and optimized for a specific purpose (such as mining cryptocurrencies).

Depending on the FPGA miner and the coin they mine, their performance can vary greatly. From a few 100 kilobytes per second to more than 20 gigahashes per second (gh/s). Each gigah is equivalent to one billion hashes.

The cost of FPGA miners also has a wide range. Prices can range from $200 to $6,000. One of the downsides of mining with FPGA is that it is usually not as user-friendly to set up as some other mining tools.

You may need to design the gate and software yourself. You can also download bitstream mining algorithm or FPGA. which simplifies the setup process. But a small flow of FPGA might cost as much as 8% of your recurring profit.
