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.

Stream processors

The number of stream processors provided by the graphics card.

A stream processor is a separate part of the GPU, designed to execute one shader at a time. Shaders, in turn, are small programs responsible for creating individual graphic effects (for example, surface gloss, glare on the surface of water, motion blur, etc.). Accordingly, the more stream processors provided in the design, the more shaders the graphics card can simultaneously execute and the higher its computing power. However, in general, this is a rather specific parameter, relevant mainly for professional developers, modders and enthusiastic gamers.

Stream processor version

The version of the stream processors used in the graphics card.

For more details on the processors themselves, see the relevant paragraph above. And the version data is ancillary information; it may be necessary for some specific tasks such as developing special software, but ordinary users and even advanced enthusiasts rarely need it. Detailed information about this parameter can be found in special sources.

Texture units

The number of texture units contained in the GPU.

As the name implies, such blocks are responsible for working with textures. Texture, in turn, is one of the main elements of 3D graphics: an image superimposed on the surface of a three-dimensional object (similar to, for example, wallpaper pasted on a wall or a label on a box). The specific purpose of texture blocks is to select textures and apply them to the surface of geometric objects. Other things being equal, more of these blocks means higher graphics performance; although in general this is a rather specific parameter, intended mainly for specialists and rarely needed by ordinary users.

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.

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.

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.
