Graphic processors have been around since the 1970s, but they are now best known for their work with real-time 3D graphics applications for PCs.
Originally, graphic processors were primarily responsible for games and 3D graphics. Nowadays, graphic processors are used to compressing video formats like MPEG-2 AVC/H.264 Blu-ray Discs which save on HD disc space by adjusting color ranges and intensities that the human eye can’t see or doesn’t notice as much in order to make file sizes smaller–rather than taking time to compress each frame individually at higher bit rates.
