A GPU or graphics card increases a computer’s ability to process complex graphics by providing hardware specifically dedicated to the task. While many laptops and desktop computers rely on the CPU (central processing unit) to render computer graphics, computers with dedicated graphics cards can outsource that process.
Visual-intensive activities, such as complex graphic design, video editing special effects, animation and PC gaming, will need a dedicated graphics card to provide the performance you desire. The card can access its own memory resources in addition to processing the graphics instructions.
To find the best graphics card for your chosen activity, consider the memory capacity you need for your activities as well as the clock speed. Clock speed indicates the speed of the GPU’s cores. Measured in megahertz (MHz), clock speed is a good indicator of how quickly your new graphics card will render the visuals you need.
