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.

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.

Fans

The number of individual fans provided in the graphics card cooling system (if any, see "Cooling").

In general, the more powerful the video adapter, the more efficient cooling it needs. So one fan is typical mainly for devices of the initial and inexpensive middle class, two — from medium to advanced, and three or more are almost an unambiguous sign of a premium-level solution. At the same time, there is no strict dependence here, and models with similar characteristics may have a different number of fans (especially since the cooling efficiency is determined not only by the number of fans, but also by their diameter). But what this parameter unambiguously affects is the length of the graphics card and, accordingly, the amount of space required to install it.

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.

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.
