This is the main performance indicator of the graphics card because it indicates the model of this card. The performance of cards of the same model is very similar and usually very different from the cards of another model.
The main difference is the manufacturer. NVidia produces GeForce series cards and AMD produces Radeon series cards. There are considerable differences between both series, GeForce cards have more successful (more stable) drivers, which improve the compatibility of these cards with games and operating systems reducing the image defect (artefact) and the cases of "hanging" to the minimum. Radeon cards usually are cheaper and consume less energy (they are technologically superior), however there might be problems with drivers and the support of games.
The choice between Radeon or GeForce series is the question of preference, similar to the choice between AMD or Intel CPU, and not always there is 100% rational justification behind it, therefore we recommend to base your selection criteria just on the games that you want to play in the near future and to find a video review in YouTube (the graphic card model + the game title) that will demonstrate exactly how the particular card handles the relevant game. The result will be obvious and usually quite close to what you get when you buy the particular or similar model card.
For making the choice easier for our customers TopPC.ee has marked the graphic cards (models) that are the best choice for playing all the newest games at a reasonable quality level with a green tick "recommended".
The RAM capacity of the video card. This is an important parameter if you want to play games of high resolution or work with a high resolution monitor. A higher memory capacity means better performance and the support to higher resolution.
Currently 1GB is the optimum capacity of the video memory.
The number of bits of the video card RAM determine what amount of information the video card memory can handle within a single clock cycle. A higher number of bits indicates higher performance of the video card.
HDMI is the digital image and sound transmission standard that allows to connect a TV set, monitor or projector supporting HDMI to the computer via the HDMI cable.
DisplayPort digital connection for the transmission of the image and sound via a single wire at a high quality level. Contrary to the HDMI, this connection allows to connect several external monitors to the computer via a single connector.
D-SUB is the classic (analogous) connection plug of monitors, projectors and other external video devices. This standard is gradually disappearing from the market leaving the space for much higher quality HDMI or DisplayPort (digitālajiem) plugs.
