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.
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.
