AMD confirms GDDR5 memory ICs will be on next generation graphics cards
AMD today announced the first commercial implementation of Graphics Double Data Rate, version 5 (GDDR5) memory in its forthcoming next generation of ATI Radeon graphics card products. The high-speed, high-bandwidth GDDR5 technology is expected to become the new memory standard in the industry, and that same performance and bandwidth is a key enabler of The Ultimate Visual Experience, unlocking new GPU capabilities. AMD is working with a number of leading memory providers, including Samsung, Hynix and Qimonda, to bring GDDR5 to market.
Todays GPU performance is limited by the rate at which data can be moved on and off the graphics chip, which in turn is limited by the memory interface width and die size. The higher data rates supported by GDDR5 up to 5x that of GDDR3 and 4x that of GDDR4 enable more bandwidth over a narrower memory interface, which can translate into superior performance delivered from smaller, more cost-effective chips. AMDs senior engineers worked closely with industry standards body JEDEC in developing the new memory technology and defining the GDDR5 spec.
