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.

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.

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.

Monitors connection

The maximum number of monitors that can be connected to the graphics card at the same time and shared.

Simultaneous connection of several screens allows you to expand the visual space available to the user. For example, it can be useful for designers and layout designers when working with large-format materials, for programmers to separate tasks (one monitor for writing code, the second for searching for the necessary information and other auxiliary purposes), and for gamers-enthusiasts — to ensure the maximum immersion effect. Thanks to advances in technology today , even low — cost graphics cards can typically handle at least three monitors, while advanced models can support four or more displays .

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.

Power consumption

Maximum power consumed by the graphics card during operation. This parameter is important for calculating the total power consumed by the entire system and selecting a power supply that provides the appropriate power.

Minimum PSU recommendation

The smallest power supply recommended for a computer with this graphics card.

This parameter, usually, is much higher than the power consumption of the graphics card itself. This is natural — after all, the PSU must provide electricity to the entire system, not just the video adapter. At the same time, the higher the power of the graphics card, the inevitably higher the power consumption of the PC as a whole. Moreover, this is due not only to the “voracity” of the graphics adapter itself, but also to the consumption of other PC components: a high-end graphics card, usually, is combined with an equally powerful (and energy-intensive) system.

With this in mind, manufacturers indicate the minimum recommended power supply. Of course, such recommendations are not mandatory; however, when using a PSU with a power lower than the recommended one, the probability of malfunctions increases significantly — to the point that even a very limited system may simply “not start”.

Length

The total length of the graphics card.

In this case, the length means the size of the device from the plate with connectors (which is attached to the back wall of the system unit) to the opposite side. The plate itself and the outwardly protruding connectors are usually not taken into account.

Data on the length of the graphics card is needed primarily in order to assess whether there is enough space for it in a particular case. In addition, longer boards, usually, have more advanced characteristics (although there is no hard dependence here, and video adapters of similar class may have different lengths). As for specific values, the most compact solutions nowadays have a size of 150 – 200 mm or less ; an indicator of 200 – 250 mm can still be considered relatively small, 250 – 290 mm — medium, and many models (mostly advanced) have a length of more than 290 mm.
