Things You Need to Know About External GPUs

Consider the main features of external video cards in the material of the article.

Purpose of an external video card

In practice, there are cases when it is physically impossible to connect a  video card since there is no full-fledged PCle port. Therefore, for online games or rendering on such a device, there is an excellent option – an external video card. This device is a device that is separately connected to a PC and is responsible for the level of image quality on the screen.

The use of this technology is quite relevant today. An external video card is a component of the system and is characterized by important functional features. It is used even for branded computer models.

Basically, external expansion cards are designed for laptops equipped with an integrated video card. In this case, the external device is connected as follows:

  • Expresscard slot – many laptop models have such a solution that allows you to connect an expansion card;
  • USB connector – a standard input on the device, which is not very fast, but as an alternative, it is quite suitable;
  • Thunderbolt is a hardware-type interface that is often required to connect a computer and a video card.

Features of external video cards

The use of an external video card in the framework of its activities has a number of advantages:

  • Ensuring high performance in resource-intensive applications and video games;
  • Eliminating the need to install an external monitor in most cases;
  • Mobility, since the device looks like a compact docking station and its transportation does not cause any special problems;
  • Low noise during operation, since when using an external video card, additional cooling operates, respectively, with efficient functioning, the load on the coolers does not increase.

Despite the rather significant advantages of expansion cards, they also have some disadvantages. One of them is the cost, which is quite high. Therefore, it is necessary to select such a device with the calculation of the budget laid down for this.

In addition, the device is quite an energy intensive and in most cases, the consumption exceeds 200 watts. This may require an additional high power supply to provide power to the video adapter.

The role of an external video card

The video card is the link between the user and the digital device. The device is used to transfer data to the monitor, which is processed by the computer. In other words, there is an interaction between man and technology.

The main role of the video adapter is to display the picture on the computer screen. The video card processes the graphic data, translate it into video signals and transfers it to the monitor. In addition to displaying the image, the video card also performs computational functions, thereby helping to offload the processor. Modern GPUs are stand-alone devices and are capable of performing a number of additional operations.

The role of an external video card is to expand the functionality of the equipment. Most manufacturers characterize the device as equipment for gamers. Assembling a separate gaming station is quite expensive and an external video adapter in this case is the optimal economical solution.

Video card selection

Purchasing an external video card for your computer is a serious task, which requires the concentration of special attention already when choosing the PC itself. It is important to determine the direct purpose of the adapter, as well as the number and type of connectors on the equipment. The characteristics of the future expansion card depend on these parameters. Of course, the issue of price is important – why overpay for additional device options if they are not needed in the process of working with it?

The most expensive docking stations are EXP GDX gaming systems, providing high-quality graphics, the level of which is worthy of FPS. If the device is required for mining, then the selection criteria should be a reliable cooling system and low noise during operation.

An important point is also the manufacturer of the video card. To date, there are some ways to save money when buying – in particular, ordering an adapter online. Usually, it comes from China, but there are also systems of domestic production. It is undesirable to choose components from little-known brands since the quality of their work is not confirmed by reliability and experience of use. In addition, a relevant aspect is the timely updating of device drivers, which most budget companies do not provide.

The key parameter of choice is the method of connecting the expansion card. Replacing the computer’s Wi-Fi module connection with the MXM is a rather complicated process. It is extremely important not to damage the equipment and install everything in working order. Therefore, when choosing an external video accelerator, it is advisable to take a closer look at models from well-known manufacturers: AMD, Nvidia, ASUS, Gigabyte, etc.

A few words at the end

In conclusion of the article, we note that an external video card is a very useful device. In some cases, its use is the only solution and provides a range of functionality.

An external video adapter is especially in demand among gamers who need high hardware performance and a sharp, detailed image. But the device is also used in other areas: mining on crypto exchanges, processing video and photo materials, working with professional design programs, rendering and 3D modelling, etc.
