Do I need a good CPU for GPU mining? (If I have good GPU)

Do I Need Good CPU for Mining if I Have Good Graphic Card?

Mining is a legal task in most countries, and most companies perform mining to collect information on a specific keyword. It helps a company grow but also helps its customers fulfill their needs by having the desired product. Mining is also an occupation of most data scientists.

Robust computer systems with more than one good graphics card are used for mining for different purposes. If you are a mining professional, this article is definitely for you. This article will discuss whether you need a good CPU for mining when you already have a good graphics card.

Do I Need a Good CPU for Mining if I Have a Good Graphic Card?

The fastest CPU present today has a maximum of 12 cores, while the two-fan economic graphics card has hundreds of cores. Hence, GPUs are more responsible for mining than central processing units (CPUs). If you have a good graphics card, you do not need a good CPU for mining if there are no bottlenecks.

The bottleneck is when your graphics card depends on your CPU to perform some action, but your CPU is delaying it because of its low power or slow speed. In this case, you must upgrade your computer processor, or your work will slow down during mining. We suggest you use a compatible CPU and GPU.

  • Remove Your AMD Crossfire and NVIDIA SLI
    First, you must remove your AMD Crossfire and NVIDIA SLI for fast mining because they will slow down the hash rate. You have to connect the GPUs without crossfire. This will give you the maximum speed you need during mining.
  • Powerful PSU
    Secondly, you need a good PSU as good graphics cards require more power to operate, and you will need at least two of them in mining. GeForce RTX 3060 Ti is considered the best GPU for mining.
  • Suitable Motherboard
    Thirdly, you need a motherboard that can handle multiple graphics cards simultaneously. Doing it professionally requires a mining rig and power supply units (PSU). Because more graphics cards will generate more heat, installing them separately using riser cards and cables is better.
  • Fast SSD
    The fourth number has the storage media you use for mining. A faster SSD (solid state drive) will allow faster mining if you use graphics cards for this purpose. Similarly, more capacity of storage devices will allow you to store more data along with the OS and other mining software.

Do Crypto Miners Use CPU or GPU?

In the old times, CPUs (central processing units) were famous for mining, but crypto miners used GPUs (graphics processing units) in the modern era.  The professionals have a computer system dedicated to mining. But it is also possible to use your computer system when performing mining simultaneously.

In this case, you will need at least two GPUs, one dedicated to mining and the other for your personal use. The mining OS and software will use one, while the other will be used for your operating system, such as Windows 10/11, MacOS, etc. The professionals also use a dedicated motherboard with a mining rig for multiple GPUs.

What CPU Do I Need for GPU Mining?

If you are mining using your graphics card, the CPU does not matter much. But there are some tasks that graphics cards depend on the CPU for. That is why we recommend you upgrade your CPU to increase your mining system’s performance and reduce bottlenecks.

Without a CPU, you won’t be able to process the programs required to perform mining. Moreover, your graphics cards also have a CPU that helps only in graphic rendering. So, that is why CPU type or hertz doesn’t matter.

If you use the latest graphics cards, you need the newest 12th-generation CPU for mining. But if you have the older GPUs, you can install intel 8th or 9th-generation central processing units. That is because, during mining, your graphics cards will carry most of the load instead of your CPU.

Does Mining Damage Your CPU?

During the process of mining, your CPU and graphics card have to work on complex algorithms, and they also have to perform calculations for hashing. As a result, both of the latter hardware generate enormous amounts of heat. If you have no mechanism for getting rid of this heat, mining will damage your CPU.

On the other hand, the same happens to your GPU. That is why professional miners install their mining setup using mining rigs and cooling kits. At least they try to keep the room temperature as low as possible. They also have software for controlling the fan speed at certain temperatures, such as powerful gaming engines.

If mining does not damage your CPU or GPU, it will shorten your hardware’s lifespan. The CPU or GPU would become out of order that you could have used for more time if you had used them for other graphics-based tasks. This is because the high temperatures generated during mining burn the cores.

Can I Use a Normal PC for Mining?

Using a standard PC (personal computer) for mining is possible, especially when crypto-mining coins like Byte, Zcash, and Monero. But there are two disadvantages to doing this. The first con is that your standard PC will mine at a prolonged speed. Secondly, the electricity bill will be higher than your mined coins.

It is also possible that not only the lifespan of your PC will decrease, but also its hardware might burn out one after another. And the depreciation cost will mine all the profit from your mining business. We recommend setting up a dedicated mining system if you want to profit from mining.

The first hardware you need is a powerful motherboard with a good CPU and RAM. But remember, we do not suggest using CPU for mining but your GPU. The second thing you need is the graphics cards and a power supply unit (PSU) to fulfill the power needs of that hardware.

The third most important thing for mining is your storage media. The faster the storage media is, the quicker the mining will be. We recommend installing SSDs (solid-state drives) instead of old, slow HDDs (hard disk drives). Your storage media should have enough capacity with a high data transfer speed.

The greater the capacity, the more the data will be stored in your storage. If you are a Windows user, we recommend installing an SSD of a minimum of 128 GB, but installing a 256 GB SSD will be the best. For Linux users, 64 GB is enough, but installing a 128 GB SSD will give you more advantage when mining.

Does GPU Mining Damage Your PC?

GPU mining, or using graphics cards, is the most popular and profitable thing compared to CPU mining. This is because GPUs have more cores than CPUs; hence, they can perform mining tasks faster than CPUs. This is why nearly all professional miners implement GPU mining.

If your GPU is installed in the PCIe slot of your motherboard for mining, then it will generate heat from time to time. If the ventilation system is poor or the GPU or other computer hardware is dusty, it will overheat the other components. As a result, either your GPU or some other hardware or device will burn out.

The other hardware at risk is your computer system’s PSU (power supply unit). That is because when your graphics cards are mining, they work on their maximum limit, especially when you have overclocked them. They draw the full power from your power supply unit in this case.

When the power demanded by the graphics cards is nearly equal to the power provided by the PSU, the power supply becomes overheating. A slight increase in the computer case, room, or rig temperature burns out the PSU. Hence, GPU mining damages your PC if you do not care for some of the last things.

Is CPU Mining Faster Than GPU?

Nearly all of the central processing units (CPUs) are capable of mining because they have hash power and can perform the same calculations as GPUs. But CPU mining is way slower than the one done by using graphics cards. This is because GPUs have more cores than central processing units.

The other reason is that graphics cards use more efficient parallel computing algorithms than CPUs. They are also dedicated to a single task compared to the CPUs. Because CPUs are not only responsible for calculations during mining, but they also control other hardware and generated addresses.

As a result, CPUs become overloaded and overheated as well. It results in a slow mining process that costs more electricity and low profits. We recommend you use graphics cards because GPU mining is way faster than CPU mining. No CPU can compete with the latest GPUs.


GPU mining is the most profitable and popular way of mining cryptocurrency. But it does not come risk-free. It might cause hardware to burn out due to overheating, lack of ventilation, or power supply problems. You can use a CPU for mining, but its performance will be extremely low compared to GPUs.
