GPU model
A GPU is a type of graphics processor that determines the fundamental performance characteristics of a video adapter. Today there are two main manufacturers -
AMD and
NVIDIA. Intel has also entered the leadership race with its
Intel Arc line of discrete graphics.

Knowing the GPU model, you can find detailed information on it (special specs, reviews, reviews, etc.) and evaluate how suitable this board is for your purposes. It is worth noting that in video cards from third-party brands, the characteristics of the graphics processor may differ slightly from the standard ones (and often in the direction of acceleration and improvement).
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.
VR
Graphics card support for
virtual reality technologies, in other words, the ability to work with virtual reality glasses.
Such glasses provide a change in the image in the eyepieces when turning and tilting the head, thus creating an immersive effect. One of the features of virtual reality is the demands on graphics performance: for example, the frame rate for normal picture perception must be at least 90 frames per second. In addition, the VR mode often uses special technologies designed to provide a comfortable experience (and also demanding on processing power).
All these points are taken into account in video cards with VR support. Note that the degree of compatibility with a specific virtual reality headset may be different, this point should be clarified separately; however, for normal work with VR, anyway, you will need a graphics card in which this feature is explicitly stated. In addition, such models will be useful for content developers for virtual reality.
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.
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.
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.
