How to Choose the Best Hardware for SHA-256 Cloud Mining
SHA-256 is a popular algorithm for mining cryptocurrencies such as Bitcoin, Bitcoin Cash, and Bitcoin SV. However, not all hardware is equally suited for this task. In this article, we will compare two types of hardware that are commonly used for SHA-256 cloud mining: GPU and CPU.
GPU stands for graphics processing unit, and it is a specialized chip that is designed for rendering graphics and performing parallel computations. CPU stands for central processing unit, and it is the main chip that runs the software and logic of a computer. Both GPU and CPU can be used for SHA-256 cloud mining, but they have different advantages and disadvantages.
GPU vs CPU: Performance
The most important factor to consider when choosing hardware for SHA-256 cloud mining is performance. Performance refers to how fast and efficiently the hardware can solve the complex mathematical problems that are required for mining. The higher the performance, the more hashes per second (H/s) the hardware can generate, and the more likely it is to find a valid block and earn a reward.
According to minerstat.com, a website that provides SHA-256 mining calculator[^1^], a typical GPU can produce between 10 and 40 TH/s (tera hashes per second), while a typical CPU can produce between 0.01 and 0.1 TH/s[^1^]. This means that a GPU can be up to 800 times faster than a CPU for SHA-256 cloud mining[^3^]. Therefore, GPU has a clear advantage over CPU in terms of performance.
GPU vs CPU: Cost
Another factor to consider when choosing hardware for SHA-256 cloud mining is cost. Cost refers to how much money you need to spend to acquire and operate the hardware. The lower the cost, the more profitable your cloud mining operation will be.
The cost of hardware can be divided into two categories: upfront cost and running cost. Upfront cost is the amount of money you need to pay to buy the hardware, while running cost is the amount of money you need to pay for electricity, cooling, maintenance, and other expenses.
The upfront cost of a GPU is usually higher than that of a CPU, because GPUs are more specialized and in higher demand. According to pc-builds.com, a website that provides bottleneck calculator[^2^], a high-end GPU such as Nvidia GeForce RTX 3090 can cost around $1500, while a high-end CPU such as Intel Core i9-10900K can cost around $500[^2^]. However, the upfront cost of hardware can vary depending on the market conditions and availability.
The running cost of a GPU is also usually higher than that of a CPU, because GPUs consume more power and generate more heat than CPUs. According to minerstat.com, a website that provides SHA-256 mining calculator[^1^], a typical GPU can consume between 100 and 300 W (watts) of power, while a typical CPU can consume between 10 and 100 W[^1^]. This means that a GPU can use up to 30 times more electricity than a CPU for SHA-256 cloud mining[^3^]. Therefore, CPU has an advantage over GPU in terms of cost.
GPU vs CPU: Bottleneck
A final factor to consider when choosing hardware for SHA-256 cloud mining is bottleneck. Bottleneck refers to the situation where one component of your system limits the performance of another component. For example, if your GPU is too powerful for your CPU, your GPU will not be able to work at its full potential, and vice versa.
To avoid bottleneck, you need to balance your hardware configuration according to your purpose. For SHA-256 cloud mining, your purpose is to maximize your H/s output, so you need to choose a GPU that matches your CPU's capabilities. According to pc-builds.com, a ec8f644aee
