The memory size or capacity of most available modern video cards ranges from a low figure of 128 MB to a high of 8 Gigabytes. Because video memory has to be accessed by the Graphics Processing Unit, and the display circuitry, it mostly uses special high-speed or multi-port memory. These include types such as VRAM, WRAM, SGRAM, and others. Approximately in 2003, video memory was usually based on DDR technology, which eventually evolved towards DDR2, GDDR3, GDDR4 and GDDR5. Modern graphics cards have an effective memory clock generally ranging between 400 MHz and 3.8 GHz.
