A graphics card is a device that allows your computer to take data from the Central Processing Unit (CPU) and turns this data into pictures. To put it simply, a graphics card allows you to see images on your computer monitor.The computer graphics card, also called the video card, works like a translator — your computer’s CPU holds data which the graphics card receives as binary data (a series of numbers made up of ones and zeroes) and then translates them into images.

 

How Do You Measure The Speed Of A Graphics Card?

Measuring the speed of your computer graphics card is not simple because there are many factors that affect how fast a graphics card can do its job and these depend on what tasks the card is performing.

The best graphics card overall performance measurement is its frame rate per second (FPS). This describes the number of images the graphics card displays per second. Although our human eyes can process 25 FPS, the best graphics card for games would require at least 60 FPS so that there is good animation and scrolling.

Frame Rate Has Several Components Such As:

Vertices or Triangles per second: Those 3-D images are made of polygons or triangles and the measurement tells you how fast the GPU builds a wire frame image. Then, the graphics card rasterizes the image (fills in the gaps or remaining pixels) while also adds color, lighting, and texture.

 Pixel Fill Rate: This give the number of pixels the GPU can process in a second, which translates to how quickly it can convert a digitized image into a format suitable for display on a computer monitor.

The hardware of a graphics cards for laptops and computer graphics card directly affects its speed. The CPU and motherboard also play a role as even the fastest graphics card will not be able to compensate for the inability of a motherboard to quickly deliver data. Also, the connection of the card to the motherboard and how fast it can get instructions from the computer’s CPU affects its functioning.
