AMD Selects Samsung's GDDR4 for ATI Radeon HD 2000 Series GPUs
Samsung announces today that its GDDR4 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.
Built with 80 nanometer process technology, the 512Mb GDDR4-based graphics cards provides 140.8GB-per-second performance – 25 percent faster than 700 MHz GDDR3 graphics memory, the most common graphics device in use today.
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 and submitted a paper on a 4Gbps GDDR4 at the International Solid State Circuits Conference earlier this year.
