GDDR

A category of DDR SDRAM chips that are made to specifically handle the enormous demands of graphics processing. Currently, three standards exist: GDDR-I, GDDR-II and GDDR-III, and almost all modern graphics cards use this type of memory. The standards differ in their clock speed, bandwidth, and power-management capabilities. GDDR is typically more expensive than DDR memory.
