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.
USB C
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.
Additional power
Format of additional power required for the operation of the graphics card.
By itself, the PCI-E connector, which is standardly used to connect video cards, provides 75 watts of power. For many models, even quite performant ones, this is quite enough, and many modern video adapters do
without additional power. However, models
with additional power have become more widespread, especially among high-end solutions.
The simplest version of such a power supply is one
6-pin or
8-pin connector. A 6-pin connector can additionally provide up to 75 watts, an 8-pin connector can provide up to 150 watts. However, for high-end solutions, one connector is not enough, so there are models with
6 + 8 pin,
8 + 8 pin, and even
8 + 8 + 6 pin or
8 + 8 + 8 pin formats.And the new cards are completely
16-pin. Such power connectors have a total of 16 lines: 12 for current supply and 4 signal. The effective power threshold of the 16 pin connector is up to 600 watts. Connection to it can be done through a 3×8 pin adapter.
Note that it is theoretically possible to connect a 6-pin power supply to an 8-pin connector and vice versa, even corresponding adapters are availa
...ble for this. However, in fact, the possibility of such a connection should be clarified separately, and such tricks should be used only in extreme cases, when other options are not available.
