Comparison XFX Radeon RX 6800 XT RX-68XTALFD9 vs XFX Radeon RX 6800 XT RX-68XTAQFD9

The number of DisplayPort outputs provided by the graphics card.

DisplayPort is a digital media interface similar in many ways to HDMI, but primarily used in computers. The specific capabilities of this interface depend on the version (see below), but even in the most modest modern version of DisplayPort, it allows at least 4K at 60 frames per second and 5K at 30 fps. Another interesting feature of this standard is the ability to daisy-chain multiple screens to one port (“daisy chain” format).

In light of the latter, we can say that the number of DisplayPort outputs corresponds to the number of screens that can be connected directly to the graphics card, without using a daisy chain. Such a connection may be required, in particular, for monitors that do not support daisy chaining. If such a mode is supported, the maximum number of screens will be at least twice as high as the number of connectors. However, it is worth considering that the resolutions supported by the video adapter itself may not reach the maximum capabilities of the DisplayPort version used.

The number of USB Type C outputs provided in the graphics card.

Note that USB Type C is only a type of physical connector; specific methods of its application may be different, they should be clarified separately. However, most video cards with this feature have VR support (see below), and this connector is used in them just to connect virtual reality glasses and helmets. Another use case is somewhat less common — connecting monitors via the Thunderbolt v3 interface: this version uses a Type C hardware connector. In both cases, there is usually only one output of this type — this is quite enough.
