Samsung announced today that its GDDR4 (Graphics Double Data Rate, version 4) high-speed graphics memory chip is being used in both the 1GB ATI Radeon HD 2900 XT and the 256MB ATI Radeon HD 2600 XT graphics processing cards. The 1GB card has the widest bus in the industry designed for full-performance, high dynamic range (HDR) rendering in PCs. GDDR4 processes video images in desktop PCs, notebooks and workstations at extremely high speeds in simultaneously moving large volumes of high-definition or other high-resolution video, such as next generation Blue Ray and full HD level video images.
Samsung’s GDDR4 memory devices are now in mass production at the 512Mb density level. Samsung developed the world first GDDR4 device last year.
