Samsung Electronics Co., Ltd. has developed the industry's fastest computer graphics memory and has shipped it to major graphics card manufacturers for testing. The GDDR4 (Graphics Double Data Rate 4th Generation) memory process es gaming and video images at 2. 5-gigabits per second (Gbps) or a staggering 10-gigabytes per second, the equivalent of transmitting 10 hours of DVD quality video, the full series of Harry Potter movies. The first GDDR4 developed is a 256Mb chip that runs at 2.5Gbps.
Graphics DRAM is a high-bandwidth DRAM memory chip capable of simultaneously processing high volumes of video exceptionally fast compared to the speed of the main computer memory – DRAM (dynamic random access memory).
