Samsung graphics memory chip finds home in next-gen graphics boards

Samsung Electronics says 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.

“We chose Samsung
GDDR4 memory for our 1GB ATI Radeon HD 2900 XT and ATI Radeon HD 2600 XT
graphics cards because its design complements our strategy in offering
leading-edge technology to a broader enthusiast gaming market,

said Vijay Sharma, Director, Product Marketing, AMD Graphics Products
committed to working with key players in the industry like Samsung to
develop advancements that work to continuously improve past solutions.

“Our GDDR4 memory enables the premium and
mainstream cards from the ATI Radeon
™ HD 2000
series to perform at their optimal levels,

said Mueez Deen, Director of Graphics Memory, Samsung Semiconductor, Inc.

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.

’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 (ISSCC) earlier this
