Not all graphics cards are created equal - each has a specific configuration that makes it suitable for a particular task like high frames per second (fps) gaming, 3D modeling, or
video editing.
GPU: The terms “graphics card” and “GPU” are often interchangeably used, but they’re not quite the same. Graphics card refers to the entire expansion chip as a whole of which the GPU is a part. The GPU is, in essence, the brain of the graphics card, which handles complex mathematical calculations to create the stunning visuals we all love. NVIDIA and AMD are the two most popular GPU makers.
VRAM: The Video RAM (VRAM) is the amount of memory available on your graphics card, measured in GB. The most common VRAM sizes include 4GB, 6GB, and 8GB. Consider getting the largest video memory you can for a superior graphics performance.
Core count: Modern GPUs are made of multiple processors called cores. While NVIDIA calls them CUDA Cores, AMD refers to them as Stream Processors. If you handle a lot of graphics-intensive tasks (think 4K video editing or gaming), prefer graphics cards with more cores over those with fewer ones.
Clock speed: Each GPU core performs a certain number of computations every second, which is determined by the clock speed (measured in MHz). For two graphics from the same architectural family, the one with a higher clock speed will outperform the other.
Resolution: Graphics cards send a stream of data to your display device via standard ports like HDMI, DVI, and USB Type-C. Each graphics card supports a set of resolutions like 4K (3840x2160 pixels) and Full High Definition (FHD, 1920x1080 pixels). If you’re into Ultra High Definition (UHD) gaming, pick a graphics card that supports 4K resolution.
Refresh rate: If you’re a
gamer, this is one really important specification to watch out for when purchasing a system. The refresh rate is the number of times your display draws an image (measured in Hz). If you enjoy high fps games, choose a graphics card with a high enough refresh rate.
Driver version: Your graphics card needs special software called the display driver to communicate with Windows. GPU makers will typically release driver updates from time to time, so it’s important to ensure you have the latest driver version.
