A graphics processing unit (GPU) is an electronic circuit that accelerates creating and rendering of images, videos, and animations. It performs fast math calculations while freeing the CPU to perform other tasks. GPUs are used in desktop computers, workstations, servers, mobile devices such as tablets or smartphones. They are also used for mining cryptocurrencies like Bitcoin.
GPUs are used in computers ranging from mobile phones to supercomputers. They often have their memory known as VRAM, which can be used for high-resolution textures and framebuffers; this memory may not be available on some models due to cost or thermal constraints.
In recent years, GPUs have become popular in consumer electronics beyond just PC gaming systems, with many companies developing dedicated hardware such as smartphones and tablets for better 3D performance than general-purpose CPUs can provide.
Modern GPUs are very efficient at manipulating computer graphics; their highly parallel structure makes them more effective than general-purpose CPUs for algorithms where large blocks of data are processed in parallel.
In addition to running traditional graphics applications such as Adobe Photoshop or CorelDRAW faster than many CPUs on their own, modern GPUs have been explicitly designed to run “general purpose” programs written by programmers using standard programming languages like C++ and Fortran 90/95 or even Java.
This has made it easy for scientists who use high-level languages like Matlab or Python but would prefer not to learn an assembly language that takes years before making practical use of it. Instead, they can now just write code that runs directly on the GPU without prior knowledge about how the hardware works.
The latest generation of these cards also includes advanced features such as video encoding acceleration, allowing you to encode your videos much faster than ever before. You can use your computer to play games with amazing 3D graphics or edit videos without lag time when you add a GPU card to it.
