Why Bitcoin Miners Favor Graphics Cards: An In-depth Analysis of the Truth Behind It

In the wave of digital currencies, Bitcoin is undoubtedly the most eye-catching star. However, with the rise of Bitcoin, the choice of mining machines has become a hot topic. Especially the use of graphics cards, many miners have found that graphics cards play an indispensable role in Bitcoin mining. So why do Bitcoin mining machines favor graphics cards so much? This article will explore the reasons behind this phenomenon from multiple angles.

First of all, the computing power of graphics cards is one of the important reasons why they are the first choice for Bitcoin mining. Graphics cards, or graphics processing units (GPUs), were originally designed for graphics rendering, but their powerful parallel computing capabilities make them excellent at handling complex mathematical problems. Bitcoin mining requires extremely high computing power to solve hash functions, a process that is very resource-intensive. Graphics cards can handle multiple tasks at the same time, greatly improving mining efficiency. Compared with traditional central processing units (CPUs), graphics cards have obvious advantages in processing large-scale data.

In actual operation, miners generally find that the cost of using graphics cards for mining is relatively low. Although the initial investment in graphics cards may be high, the energy consumption and maintenance costs of graphics cards are relatively low during the long mining process. For example, some models of graphics cards can process millions of hash operations per second, while the CPU under the same conditions may only process a few thousand times. Behind this high efficiency, it means that miners can find blocks faster and thus get more Bitcoin rewards.

In addition, the popularity of graphics cards is also a reason for their popularity. Today, there are many types of graphics cards on the market, ranging from high-end to entry-level, and miners can choose the right model according to their budget and needs. This flexibility enables more individuals and small miners to participate in Bitcoin mining, lowering the entry threshold. Especially in some countries and regions, the supply of graphics cards is relatively sufficient, and miners can more easily obtain the equipment they need.

Another major advantage of graphics cards is their good heat dissipation performance. Bitcoin mining is a high-intensity job, and the mining machine will generate a lot of heat when running. Graphics cards are designed with this in mind, and are usually equipped with an efficient heat dissipation system that can maintain a stable operating state during long mining processes. In contrast, some dedicated mining machines may have deficiencies in heat dissipation design, causing the equipment to overheat, thereby affecting mining efficiency and equipment life.

Although graphics cards have many advantages in Bitcoin mining, they are not without flaws. First, the price of graphics cards fluctuates greatly, especially when market demand is high, prices tend to rise rapidly. This puts some miners under great financial pressure in the early stages of investment. In this context, many miners began to try to buy graphics cards through the second-hand market. Although this method can save costs, it also increases the risk of unstable equipment quality.

Secondly, as the competition in Bitcoin mining becomes increasingly fierce, miners are facing increasing pressure. The increase in network difficulty has gradually reduced the benefits of mining, especially in areas with high electricity costs, which further compresses the profit margins of miners. In this case, the balance between the cost of using graphics cards and mining benefits becomes more critical.

The power of the community cannot be ignored in the mining journey of miners. Many miners share experiences and exchange technologies through online forums, social media and other platforms. This information sharing has further improved the efficiency of graphics card usage. Many miners have accumulated rich experience in adjusting graphics card parameters and optimizing mining software. Through continuous trial and error and summary, they finally achieved higher mining efficiency. This community culture not only promotes the exchange of technology, but also enhances the connection and cooperation between miners.

It is worth noting that with the development of blockchain technology, more and more mining methods have emerged. For example, ASIC (Application Specific Integrated Circuit)-based mining machines have gradually become dominant in Bitcoin mining. This type of mining machine is designed specifically for mining, and its computing power far exceeds that of graphics cards. However, the flexibility and versatility of graphics cards still make them competitive in certain specific scenarios. Especially in some emerging cryptocurrency mining, graphics cards are still the preferred device.

In addition, as the world pays more attention to green energy, miners are also beginning to explore more environmentally friendly ways of mining. The use of graphics cards can be combined with renewable energy sources, such as solar and wind energy, to a certain extent, and miners can use these clean energies to reduce the carbon footprint of mining. This trend is not only in line with the goal of global sustainable development, but also opens up a new profit model for miners.

In summary, there are many reasons why graphics cards play an important role in Bitcoin mining. Whether it is their powerful computing power, relatively low cost of use, or good heat dissipation performance and market popularity, graphics cards have become the first choice for many miners. However, with market changes and technological advances, miners need to constantly adjust their strategies and find the best mining solutions. In the future, with the emergence of more innovative technologies, the Bitcoin mining ecosystem will be richer, and miners will face more opportunities and challenges.

In this ever-changing currency world, every decision and investment made by miners is a careful consideration of the future. The choice of graphics card is not only a technical consideration, but also a sensitive capture of market trends. In this context, graphics cards are not only tools in Bitcoin mining, but also partners for miners to explore the world of digital currency, helping them to keep moving forward on this challenging road.

At present, the main way to mine Bitcoin is through mining machines, which makes the selection of Bitcoin mining machines very important, especially the core configuration of Bitcoin mining machines, graphics cards. Since mining Bitcoin is to use graphics cards to perform continuous general calculations, graphics card burnout often occurs. So, why do Bitcoin mining machines burn graphics cards? Next, the Bitcoin editor will take you to learn more about it.
 Why do Bitcoin mining machines burn graphics cards?
The key to understanding this issue is to answer why graphics cards are used in Bitcoin mining.
As Bitcoin mining becomes increasingly popular, many people must know that GPU mining speed is much higher than CPU mining speed. Of course, even if GPU computing cannot be compared with professional mining machines, it does not prevent amateur miners from admiring GPU computing. So why does GPU computing have an absolute advantage over CPU in Bitcoin mining? Let me explain it to you.
First of all, the CPU and GPU have different designs for different missions in the computer:
1. The CPU is mainly optimized for serial instructions, while the GPU is optimized for massively parallel computing.
2. Modern multi-core CPUs target instruction set parallelism (ILP) and task parallelism (TLP), while GPUs target data parallelism (DLP).
GPUs often have larger bandwidth memory, also known as video memory, so they will have good performance in high-throughput applications.
The CPU needs to be highly versatile to handle a variety of data types, and logical judgments will introduce a large number of branch jumps and interrupt processing. All of these make the internal structure of the CPU extremely complex. GPUs, on the other hand, are faced with highly unified, non-interdependent large-scale data and a pure computing environment that does not need to be interrupted.
GPU uses a large number of computing units and a very long pipeline, but only has very simple control logic and no cache. The CPU not only has a lot of space occupied by cache, but also has complex control logic and many optimization circuits. In comparison, the computing power is only a small part of the CPU. So unlike the CPU, which is good at logic control and general data operations, the GPU is good at large-scale concurrent computing, which is suitable for password cracking.
In simple terms, CPU is a general-purpose computing function. It can be used for brainless and brute-force computing, whether it is 100 children sharing apples or simulating the earth, it can be decomposed into 1+1=2, the most basic brute-force calculation. GPU is specially designed to handle high-order mathematical algorithms, such as calculating the relative positions of light sources, objects, viewpoints, and shadows, which requires trigonometric functions. Bitcoin miners use SHA-256, a secure hash function invented by the National Security Agency of the United States, which is generally used for password encryption and decryption. This algorithm performs a large number of 32-bit integer circular right shift operations (Right-
Rotate), which is very suitable for GPUs that are good at large-scale concurrent computing and password cracking.
Take Folding Home as an example. Folding Home is a distributed computing project that studies protein folding, misfolding, aggregation, and related diseases caused by them (similar to the Bitcoin model).
F H only supports CPU, and later added support for PS3 game consoles, but also uses the built-in CELL processor for calculation. F H opened a new page for GPU computing due to the participation of ATI.
H second generation GPU client can already support ATI and NVIDIA's full range of DX10 11 GPU.
The calculation time using CPU takes more than 52 days (i7-2600K)
Using GPU computing time only takes 7 hours and 11 minutes (GTS450)
Not only is there a huge gap between CPUs and GPUs, but there are also considerable differences between GPUs of different architectures. Bitcoin calculations are based on the SHA-256 algorithm, which has a large number of bit operations "Right-
Rotate", for this operation, AMD graphics cards only need 1 hardware instruction natively, while NVIDIA cards need 3 hardware instructions to simulate it. Therefore, even if the number of computing units is close, the mining efficiency of AMD graphics cards is still higher than that of NVIDIA graphics cards.
Of course, there are also YaCoins that use dynamic hashing algorithms and are limited to CPU mining. Currently, they do not support GPU or ASIC mining machines. Those who want to use CPU mining can pay attention to them. If you occasionally play with mainstream Bitcoin, GPU is still the best choice. Therefore, Bitcoin mining machines mainly obtain Bitcoins through graphics card processing and calculation, which naturally consumes graphics cards.
