What is Graphics Card ? (click to see more info)

The graphics card is primarily responsible for generating and displaying images. In addition, it increases the performance of the computer and supports CPU calculations. The right choice should be important, above all, for people using professional graphics programs and technologically advanced games.

MANUFACTURERS

There are two main manufacturers of discrete graphics cards, AMD and Nvidia- Some users have allegiances to a particular brand but each will do the same job. AMD also produce some integrated graphics option as well.

VRAM

it has a large impact on the smoothness and graphics of the game and performance in graphics programs. It stores data about the currently processed image, for example textures. The larger the capacity, the more details in better quality can be displayed on the screen. About 6 GB is good in nowadays.

Type of memory

The type of memory determines the file transfer bandwidth through the graphics card, which affects its performance. The higher the number in the name, the newer the standard and the better the memory performance, the newer the GDDR6, but lots of graphics cards have GDDR5 which is good.

Memory clock

The faster the memory clock speed is, the faster the graphics chip processes the resources that memory stores.In practice, this means rendering games or high-resolution images faster.

Memory bus

The memory bus transfers data between the graphics card core and his memory. In this case, the number of transmitted bits in a single clock cycle is important.The wider the bus, the more bits it has, and more data it can transmit. However, this does not always translate into higher performance, as the processor used and the type and amount of VRAM are also important. 192 bits are good quantity in nowadays .

Types of Cooling

Graphics card cooling is divided into air and water. This air can be: active, semi-passive and passive, the best of which is semi-passive, because it offers a balance between cooling and working culture. Water cooling is by far the most efficient and quietest, and it can cover the graphics card, part of it, or the entire computer.

CUDA

CUDA cores work in a similar way to CPU cores, however they are in the GPU and are much smaller, so there can be hundreds or even thousands of them. Unlike regular cores, they only perform tasks related to generating graphics. As a result, game loading times are shortened, and the lighting and shading of the scenery is even more realistic.

Ray tracing

Ray tracing is a ray tracing technique used to generate global lighting in the game in real time. This technology will allow you to see realistically reproduced shadows and reflections and light reflections on surfaces, greatly enhancing the visual game experience.

OUTPUT SUPPORT

VGA is a display standard developed by IBM, this is an old connector, but can still be found on graphics cards. VGA provides 640 x 480 (HD resolution color display screens with a refresh rate of 60 Hz and 16 colors displayed at a time. If the resolution is lowered to 320 x 200, 256 colors are shown.

VGA utilizes analog signals, which means it's only capable of lower resolutions and a lower quality display on screens.

DVI can send an image with a resolution 2560 x 1600 and refreshing 60Hz or 1920 x 1080 (Full HD) with refreshing 144 Hz - provided that we are using the Dual Link version.

HDMI they come in different standards and each of them gives us different possibilities. Currently, the latest HDMI standard is 2.1, with a resolution of 7680 x 4320 pixels . This means that we can use it to send an image with a resolution of 8K, and even up to 10K in 120 Hz. However, the standard is a 1920 x 1080 resolution with a refresh rate of 60 Hz.

DisplayPort this is a new connector allows you to send the image at a resolution of 7680 x 4320 (8K) at a refresh of 60 Hz or 3840 x 2160 (4K) at a refresh of 240 Hz.
