Resolution: Graphics cards send a stream of data to your display device via standard ports like HDMI, DVI, and USB Type-C. For two graphics from the same architectural family, the one with a higher clock speed will outperform the other. 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.Ĭlock speed: Each GPU core performs a certain number of computations every second, which is determined by the clock speed (measured in MHz). While NVIDIA calls them CUDA Cores, AMD refers to them as Stream Processors. Consider getting the largest video memory you can for a superior graphics performance.Ĭore count: Modern GPUs are made of multiple processors called cores. The most common VRAM sizes include 4GB, 6GB, and 8GB. VRAM: The Video RAM (VRAM) is the amount of memory available on your graphics card, measured in GB. NVIDIA and AMD are the two most popular GPU makers. The GPU is, in essence, the brain of the graphics card, which handles complex mathematical calculations to create the stunning visuals we all love.

Graphics card refers to the entire expansion chip as a whole of which the GPU is a part. GPU: The terms “graphics card” and “GPU” are often interchangeably used, but they’re not quite the same. 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.
