Memory Size indicates the amount of RAM a particular graphics card has. The amount of RAM is important because it affects both resolution and quality settings. For instance, cards with more RAM are better equipped to handle high-resolution games and higher texture quality settings.

Display Ports indicates which audio/video interface standard a particular graphics card supports. Interface standards are important because they indicate the possible use cases of a particular card.

HDMI Ports indicates the version and quantity of HDMI ports a particular graphics card supports. For example, HDMI 2.0 x4 means that particular card has four HDMI version 2.0 ports. The version number and quantity are important because they indicate the possible use cases of a particular card.

DisplayPorts indicates the version and quantity of DisplayPort interfaces a graphics card has. For example, DisplayPort 1.4 x6 means that card has six DisplayPort version 1.4 ports. The version number and quantity are important because they indicate the possible use cases of a particular card.

DMS-59/VHDCI indicates whether a graphics card has a DMS-59 or a VHDCI connector. Both are commonly found on graphics cards and provide an interface for attaching multiple peripheral devices via a single slot.

Bus indicates the type of interconnect and the number of configurations a particular graphics card has. PCIe is the current standard for making these connections. There are multiple versions of PCIe. In general, the higher the PCIe version, the greater the bandwidth and better the performance.

Digital Resolution indicates the maximum digital resolution a graphics card can output to at least one of its supported displays. Digital resolution can mean that each of the supported displays can output that resolution or that the total digital resolution is divided between each of the displays.

Memory Type indicates the type of memory interface a particular graphics card uses. In general, HBM yields better performance, lower power, and costs more than its GDDR counterpart.

DirectX is a collection of application programming interfaces (APIs) designed by Microsoft to handle certain multimedia and game development tasks on Microsoft platforms. There are multiple versions of DirectX. The higher the version number, the more advanced the version.

CrossFire/SLI indicates whether a particular graphics card supports NVIDIA SLI or AMD Crossfire technology. These technologies allow users to run two or more graphics cards at once. Each technology has different compatibilities, so knowing which technology a particular card supports is important.

Cooling System indicates which type of cooler a particular GPU uses to dissipate heat. There are multiple types of coolers, but three of the main systems are passive, active, and liquid. Liquid systems are the most effective, followed by active (fans), and then passive (no fans).

Core Clock indicates the base operating frequency, or speed, of a particular graphics card. It?s measured in megahertz (MHz). In general, better clock speed means better performance.
