A plug-in card in a desktop computer that creates the electronic signals required by the monitor. In early PCs, a graphics card was commonly plugged into the peripheral bus. Later, graphics circuits were built onto the motherboard and the cards became the domain of gamers, who want the latest and fastest NVIDIA card, the newest of which can cost more than the computer (see
RTX). Microsoft calls a graphics card a
display adapter.
Graphics Cards Are GPUs
Graphics cards contain a graphics processing unit (GPU) chip that performs parallel operations at high speed. Because AI requires massive amounts of parallel computations, the GPU is the primary processor, and millions of GPU modules are used in AI datacenters. NVIDIA leads this industry by a huge margin. See
GPU,
NVIDIA and
display standards.
All Shapes and Sizes
The left and middle cards are earlier graphics cards. On the right is a GPU, and they are all large due to their built-in cooling system.
A Gamer's Dream Card
NVIDIA graphics cards are designed for good looks as well as function. This RTX4090 has 24GB of RAM and 16,384 CUDA cores, which are the processing units in an NVIDIA GPU. See
CUDA.
