How to choose your i7 desktop PC

Finding a computer that suits us and can meet our expectations perfectly is often difficult. To help you make your choice, consider the following criteria.

#1 - The power of the processor

The power of the i7 desktop PC depends on the power of its processor. To find out how powerful the processor is, you need to consider the number of cores and threads, the frequency and the cache memory.

  • Cores or cores are small computational units. The more cores there are, the more data the processor can process simultaneously. i7 desktop processors can have 2, 4, 6 or 8 cores. The 2-core models are intended for office use. Those with 4 cores are sufficient for light gaming, while the versions with 6 or 8 cores are perfect for heavy gamers and heavy tasks such as image processing.
  • Each core of the processor performs only one task in its entirety. Threads divide the tasks into subtasks that are processed in parallel. This increases the performance of the processor even further. The number of threads is therefore a factor in choosing a powerful processor. Choose a processor with more threads.
  • The frequency determines how fast the processor can calculate and process data. It is expressed in GHz. The higher the frequency, the more complex tasks the desktop computer can perform, such as gaming or video editing. Core i7s typically range from 1.8 GHz to 3.6 GHz. It can reach 5.1 GHz in Turbo Boost mode.
  • The cache memory is used to temporarily store information, data and programs that are regularly used so that they do not need to be processed. This improves the processor's execution speed. A larger cache memory contributes to the fluidity of the system. It is measured in megabytes.

#2 - The RAM or random access memory

RAM works in concert with the processor. It ensures that your i7 desktop PC processes information quickly. It's advisable to choose at least an 8GB RAM. But if you want to play video games or edit videos, 16GB RAM is necessary to avoid latency.

#3 - The graphics card or GPU

The graphics card performs the complex calculations of image processing to quickly generate crisp and clear rendering, edit videos, and complete design tasks. This component of the i7 desktop PC can be integrated or dedicated. The integrated graphics card is built directly into the processor. It uses the power and RAM of the processor to operate.

The dedicated graphics card, on the other hand, is a separate component from the processor and has its own RAM. It is generally more powerful than the first type of GPU and indispensable in gaming or video editing.

#4 - The hard drive

The hard drive has the mission of storing all the data of your i7 desktop PC. It exists in two models: the HDD and the SSD. Less expensive, the former offers a much larger storage capacity (which can go beyond 4TB). It is mainly used to store several heavy files.

The second is more expensive and more limited in terms of storage capacity. But it has the advantage of offering a faster reading and writing speed thanks to its particular construction. With an SDD hard drive, the PC startup and the loading rate of games, applications and movies are faster.

#5 - The connectivity

Own a CPU with many different connectors allows for a wider use. But it will all depend on your need. In addition to USB 2.0, USB 3.0, or USB Type-C ports, you can check to see if the CPU has 3.5mm jack ports for audio output, an HDMI port for your TV, an Ethernet port, a built-in wifi antenna, or Bluetooth connectivity.

How to install an i7 desktop processor?

If you find that your desktop PC is outdated (duo core, i3, i5), you will surely need to upgrade to i7, it is more convenient to perform multiple tasks or get more performance in video games. Getting an i7 desktop PC is easy as long as your motherboard is compatible.


So follow these steps to change your desktop PC processor to i7.

  • Carefully read your motherboard's documentation to determine its socket type (a small square area dedicated to holding the processor). Note that processors from the same manufacturer do not necessarily use the same socket. You should also know the age of your motherboard. If it is more than 5 years old, changing the processor would be counterproductive, as there will be a power supply problem. This forces you to opt for an old processor.
  • In case you no longer have your motherboard manual, install the CPU-Z software which is free and compatible with all versions of Windows. After downloading, launch the CPU-Z program by simply clicking on the icon that represents it on the desktop. This program will give you the necessary information about your motherboard. That is: the brand, model and type of your socket.

Steps to take after checking the motherboard

Before opening your computer's case, start by turning it off and unplugging all its cables. Then, place the computer on its side to remove the screws that hold it in place. Make sure you are grounded before opening the case and touch a water faucet or wear an anti-static wristband before coming into contact with its components.

  1. Locate the processor cooler. All processors have a fan installed on top to prevent any overheating. You will need to remove it in order to access the processor. Unplug the cable that connects the fan to the motherboard as well as all the components in order to easily access the processor.
  2. Unplug the cable then now remove the fan from the motherboard. Most have four pins that can be undone with your fingers or a flathead screwdriver. After removing the fan from the motherboard, it may still be attached to the processor because of the thermal paste. However, gently twist the heat sink back and forth until it comes off the processor.
  3. To release the processor from the socket, lift the lever near it. Gently remove the processor vertically.
  4. Pull your i7 processor out of its plastic anti-static pouch. Pick it up by its two opposite edges (do not touch the pins, which are very fragile). Place it gently into the socket of the motherboard. However, make sure the pins are aligned opposite the socket holes (without forcing) until it clicks into place. Put some thermal paste on the top surface of the processor. This will ensure heat conduction between the processor, the metal fan socket.
  5. Place thermal paste on the top surface of the processor. A large drop of paste is enough to ensure heat conduction between the processor and the metal fan base.
  6. Reinstall the fan so that it is secure. Then reconnect all the cables as well as all its components as they were before. You can do a little recap to make sure that no connections are forgotten.
  7. That's it you now have an i7 desktop PC.
  8. Replace your case by firmly fixing all the screws. Put your i7 desktop PC case back on its feet and reconnect all the cables to its back panel.
  9. Power up your computer if you made the processor change without changing the motherboard.
  10. If you changed the motherboard and processor, you should easily end up with an operating system installed on your hard drive. In case your PC does not restart normally, it is necessary to reinstall your operating system.

The different types of i7 desktop PCs

The i7 version is considered top of the line for Intel processors when it comes to a desktop PC. Like all other desktops, it comes in traditional, compact and all-in-one models.

Traditional i7 desktop PC

A traditional i7 desktop computer is composed of a large and spacious vertical case. It is for its size that it is usually placed under the desk. Although bulky, this type of PC offers unparalleled versatility. You have the ability to upgrade or replace parts. This can extend the capabilities or life of the device.

However, the major advantage of using a traditional i7 desktop PC is that it is easy to access. That is, you can easily repair it, clean it, or replace a few parts. But like any other device, an i7 desktop PC also has its drawbacks. It consumes more power compared to those with core-2 duo processors. Also, it is sensitive to higher voltages.

All-in-one i7 desktop PC

It is a desktop PC that combines all the components (screen and computer). Usually, the computer itself is integrated behind the screen. As a compact i7 desktop PC, it is a space-saving and, above all, elegant alternative. Although this model does not have the expansion capability of a traditional case, it is convenient if you are looking for a powerful system for professional use or a basic desktop computer.

When it comes to power consumption, the all-in-one computer is the most energy-efficient. That's because you only need to power the monitor and the PC will turn on to run. Unlike traditional desktop computers, few power points are needed with an all-in-one model. However, its repair process is still very difficult because of its compact and slim design. When you need to repair it, you need to call an expert. Besides, the parts of an all-in-one are not easily available in the market.

Compact i7 desktop PC

Generally known as SFF (small form factor) computer, it is an i7 desktop PC that have reduced components like an all-in-one, but without a built-in screen. In other words, it's a small, low-power, quiet computer with high performance. Compared with a traditional i7 desktop PC, it is very convenient to carry because of its size. It brings great convenience to work.

Thanks to its compact size, it can stand or lie down, or even be fixed by a hanger. By adopting this type of i7 desktop PC, you will have a clean space and a tidy desk. But one of the drawbacks of this model of computer is the lack of expandability. It is almost impossible to change its components. This can be a major problem for those who plan to expand the capacity of their PC.

i7 or i5 desktop PC?

i7 desktop PC

i7 desktops are generally high-end computers. Most of them have a very powerful Intel Core i7 processor that allows them to perform very demanding tasks, such as video encoding, 3D rendering or video games. In addition to enjoying a high frequency and having multiple cores and threads, the cache memory of this central component of these computers is also larger (8 MB on average). This means that it can store huge amounts of data and increase system capacity. For example, there will be less lag when you play video games. Your streaming will also be extremely smooth.

But i7 desktop PCs also have their drawbacks. Due to their very high power, their power consumption is higher. In addition, some models feature a processor with only 2 cores. This classifies them as low-powered PCs, suitable mainly for office use. The last and most obvious shortcoming of i7 desktops is their more expensive price.

i5 desktop PC

i5 desktops often come with a 4-core processor. This is already powerful and more than enough for most people. With this level of power, it is already possible to work with applications that are not very demanding. Some i5 desktop PCs have a 6-core processor, a high clock speed (up to 4.50 GHz) and a remarkable cache memory (12 MB). This means that these models easily handle complex workflows and heavy workloads and even rival some of the higher-end PCs.

The i5 desktops can also multiply their power. And that's thanks to Hyper-Threading and Turbo Boost technology. However, while some of these mid-range PCs are powerful, many of them don't have enough multitasking performance. This is because their processors have fewer cores and support fewer threads. They are less sophisticated.


Desktop PCs are objectively more powerful than i5 desktop PCs. Their processors have a better hardware architecture and better specifications. However, always be sure to consider the criteria mentioned above, as you may end up with a desktop PC that doesn't live up to your expectations if you haven't made the right choice.

Why buy an i7 desktop PC?

For a more modern computing experience
The main advantage of an i7 desktop PC is that it has a robust hardware specification. Technical specifications often range from 4 to 8 processing cores, 8 to 12 MB of cache. It also has better integrated graphics than the Intel Core i5. Also note that it is part of desktop PCs that has the most powerful processor of the entire Intel Core range before the introduction of i9.

For easy upgrade and repair
It is more than obvious that upgrading desktops is much easier. This is also the case with an i7 desktop PC. You have the ability to upgrade all the parts that make it up. Whereas when it comes to a laptop, you would usually have to buy a brand new one to get high performance. In other words, most laptops limit their upgrade options to memory and storage.

A desktop PC with a power-saving solution
Most i7 desktops come with a Turbo Boost system. It not only saves more power, but also gives them an overclocking feature. In short, it implements this function more efficiently to achieve higher clock speeds. Thus helping it to run faster than their base clock speed. The Core i7 implements this function more efficiently to achieve higher clock speeds.

A better ally for gamers
If you are a true gamer, opting for an i7 desktop PC instead of a laptop would be an excellent choice, as its performance and functionality is best suited for video games. This is because it allows you to accommodate a more powerful graphics card that ensures an absolutely wonderful gaming experience.

Unmatched durability
Because desktops are larger and easier to cool, thermal damage is much less of a threat to their components than it is to laptops. Better temperature control means computer parts last longer. Similarly, solid-state drives (SSDs) withstand the effects of time much longer than traditional spinning-platter hard drives. Fewer moving parts greatly reduce the risk of mechanical failure.

Organize your i7 desktop cables.

Always take the time to unclutter the snaking masses of cables coming out of your multi-socket as well as the ports on your i7 desktop PC. You can do this by using a rotating power strip, cable color codes or cable clips. Better yet, you can set up a wire organizer panel that can accommodate multiple wires.

Don't forget to update your operating system.

Whether you're a fan of Windows, Mac OS, or Linux, updating your desktop PC is important when new patches are available. This ensures that your computer stays on top of performance power. However, some updates take longer. So set aside time before bed or during a break in the day so that you don't interrupt your workflow.

Clean your i7 desktop keyboard and case.

To avoid having to work on sticky keys that are hard to press, it's crucial not to neglect cleaning. For the keyboard, food crumbs, dust, as well as other dirt can stick easily. Its cleaning consists in unplugging it from the USB port or turning it off if it is a wireless model. Then take compressed air and spray it about 1 cm from the keys. Use at the end, a damp microfiber cloth to remove any excess dust or dirt.

Always back up your data!"

i7 desktop PCs almost come with automatic backup features. But, owning a modern computer means being prepared for the unexpected. This means that sudden crashes, untimely crashes can still happen. Thus, backing up files is a very important step that PC users should do themselves. Indeed, your computer is replaceable, but without backup, your information is not. All your important data should be kept both on your computer and on the external hard drive or in the cloud.

Boost your i7 gamer desktop.

The following tips will help you boost your i7 desktop PC

  1. Update the drivers: it is essential to update the graphics card of your computer. This will help to maintain its performance.
  2. Install the latest updates for the games you play to have more fluidity.
  3. Perform a hard drive defragmentation to get a performance boost. Slot changes can fragment data and will make your system work much harder. To defragment the hard drive, click on "all programs → Accessories → System Tools". This can give you a real performance boost.
  4. Disable any 3D effects that you think are unnecessary.
