GDDR3 SDRAM (Graphics Double Data Rate 3 SDRAM) is a type of DDR SDRAM specialized for graphics processing units (GPUs) offering less access latency and greater device bandwidths compared to DDR2 SDRAM of the same generation. Its specification was developed by ATI Technologies in collaboration with DRAM vendors including Elpida Memory, Hynix Semiconductor, Infineon (later Qimonda) and Micron.^[1] It was later adopted as a JEDEC standard.
