Comparison Sapphire Radeon RX 7800 XT 16GB vs XFX Radeon RX 7800 XT Speedster QICK 319

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.

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.
