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.
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”.
Low profile
This category includes video cards that have a reduced height and are suitable for installation in compact cases that are compatible only with
low profile (low profile) components. Usually models of this type are supplied with interchangeable bars — for compact and for full-size cases. At the same time, the performance of low-profile models is generally lower than that of similarly priced regular-sized options. Therefore, it is worth specifically looking for such a card only in the case when compactness is a decisive factor.
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.
