For mining

Graphics cards specially designed for cryptocurrency mining(BitCoin, Ethereum, etc.). In this case, it is not just a theoretical possibility to use a graphics card for mining ( many “regular” graphics cards have this possibility), but an optimized design, originally developed taking into account the specifics of the process. Some of these models may be mining-only and may not have video outputs at all.

Mining is the process of "mining" a cryptocurrency by performing special calculations. The technical features of the process are such that in order to achieve maximum efficiency, it is necessary to parallelize the calculations as much as possible. It is thanks to this that graphics cards turned out to be very convenient for mining: the number of individual cores (and, accordingly, parallel computing) in modern GPUs is in the hundreds. Initially, such an application was abnormal, and to transfer the graphics card to the mining mode, one had to resort to various tricks; however, in light of the growing popularity of cryptocurrencies, many manufacturers began to produce video adapters specifically designed for this application.

Memory size

The amount of own memory of the GPU; this parameter is sometimes called the amount of graphics card memory. The larger the amount of GPU memory, the more complex and detailed picture it is able to process in a period of time, and therefore, the higher its performance and speed (which is especially important for resource-intensive tasks like high-end games, video editing, 3D rendering, etc. ).

When choosing, it is worth considering that the performance of a graphics card is affected not only by the amount of memory, but also by its type, frequency of operation (see below) and other features. Therefore, situations are quite possible when a model with less memory will be more advanced and expensive than a more voluminous one. And you can unambiguously compare with each other only options that are similar in other memory characteristics.

On the modern market, there are mainly video cards with memory capacities of 2 GB, 4 GB, 6 GB, 8 GB, 10 GB, 11 GB, 12 GB, and 16 GB or even more can be installed in the most advanced models.

GPU clock speed

The frequency of the graphics processor of the graphics card. As a general rule, the higher the frequency of the GPU, the higher the performance of the graphics card, but this parameter is not the only one — a lot also depends on the design features of the graphics card, in particular, the type and amount of video memory (see the relevant glossary items). As a result, it is not unusual for a model with a lower processor frequency to be more performant of two video cards. In addition, it should be noted that high-frequency processors also have high heat dissipation, which requires the use of powerful cooling systems.

Memory clock

The speed at which a video card can process data stored in its video memory. In fact, the indicator determines the maximum number of operations to receive or transmit data by a memory module per unit of time. This frequency is expressed in megahertz (MHz) – millions of operations per second. High video memory frequency helps improve performance when performing resource-intensive tasks such as texture processing, graphics rendering and other graphics operations. However, the parameter is by no means the only factor that influences the overall performance of the video card – it is important to take into account the GPU architecture, number of cores, core frequency and other characteristics.

Max. resolution

The maximum resolution supported by the graphics card — that is, the largest image size (in pixels) that it can display on an external screen.

The higher the resolution, the clearer and better the picture is. On the other hand, with an increase in the number of pixels, the requirements for computing power and, accordingly, the cost of a graphics card increase. In addition, do not forget that you can only appreciate the full benefits of high resolutions on monitors with the appropriate characteristics. On the other hand, in the graphics settings, you can set lower resolutions than the maximum; and a good resolution margin means a good overall performance margin.

As for specific values, the actual minimum for modern video cards is 1600x1200, but higher rates are much more common — up to Ultra HD 4K and Ultra HD 8K.

DVI-D

The number of DVI-D outputs provided by the graphics card.

The DVI-D interface provides digital video signal transmission. Depending on the version, the maximum resolution of such a video can be 1920x1200 (Single Link) or 2560x1600 (Dual Link); the specific version used generally depends on the general purpose and price point of the graphics card. However, anyway, this interface is very popular in modern monitors, but it is almost never found in other screens.

The presence of several outputs allows you to connect several screens to the graphics card at the same time — for example, a pair of monitors for organizing an extended workspace. Specifically, up to 4 DVI-D outputs can be provided.

HDMI

The number of HDMI outputs provided by the graphics card.

HDMI is by far the most popular interface for high-definition video and multi-channel audio (it can be used for video and audio at the same time). This connector is almost standard for modern monitors, in addition, it is widely used in other types of screens — TVs, plasma panels, projectors, etc.

The presence of several outputs allows you to connect several screens to the graphics card at the same time — for example, a pair of monitors for organizing an extended workspace. However, there are never more than 2 HDMI ports in video cards — for a number of reasons, for several screens at once, in this case it is easier to use other connectors, primarily DisplayPort.

DisplayPort

The number of DisplayPort outputs provided by the graphics card.

DisplayPort is a digital media interface similar in many ways to HDMI, but primarily used in computers. The specific capabilities of this interface depend on the version (see below), but even in the most modest modern version of DisplayPort, it allows at least 4K at 60 frames per second and 5K at 30 fps. Another interesting feature of this standard is the ability to daisy-chain multiple screens to one port (“daisy chain” format).

In light of the latter, we can say that the number of DisplayPort outputs corresponds to the number of screens that can be connected directly to the graphics card, without using a daisy chain. Such a connection may be required, in particular, for monitors that do not support daisy chaining. If such a mode is supported, the maximum number of screens will be at least twice as high as the number of connectors. However, it is worth considering that the resolutions supported by the video adapter itself may not reach the maximum capabilities of the DisplayPort version used.

Lighting

The graphics card has a backlight system. This feature gives the board an original appearance, which is especially appreciated by gamers and fans of external PC modding. The backlight may have a different colour, in some models this colour may even change. At the same time, note that this feature does not affect the functionality of the graphics card, but it significantly affects the cost. So it's worth specifically looking for a graphics card with backlighting only in cases where an unusual design is no less important to you than performance. It should also be borne in mind that such adapters must be installed in the appropriate cases — open or with a viewing window, otherwise the backlight will simply not be visible.
