It is made up of three linked PCBs that each have its own processor and memory. The PGC was the most powerful graphics card for the IBM XT at the time of its debut, and it was designed for activities like CAD. Professional Graphics Controller provided a maximum resolution of 640x480 pixels with 256 colors and a refresh rate of 60 hertz, which was greater than the Color Graphics Adapter and Enhanced Graphics Adapter.
