Infineon Technologies AG and Samsung Electronics Co. Ltd. are separately moving to raise the bar for graphics memories in PC applications.
Samsung claims that it is mass producing the fastest graphics memory device in the world — a 900-MHz Graphics Double Data Rate 3 (GDDR3) chip.
The 512-Mbit 900MHz GDDR3, aligned in 32 rows of 16-Mbit chips, is enabling high-speed 256- and 512-megabyte (MB) graphics cards. The device is said to be 50 percent faster than the previous computer memory chip produced in large volume.
In a separate announcement, rival Infineon (Munch, Germany) said that its 512-Mbit GDDR3 graphics DRAM were selected by ATI Technologies for use with its Mobility Radeon X1600 graphics processor targeting notebook PCs.
The Mobility Radeon X1600 is ATIs new mobile graphics processor. Infineon's 512-Mbit GDDR3 graphics DRAM for high-performance mobile and desktop 3D graphics applications supports clock frequencies of up to 800-MHz and uses a 32-bit interface.
According to Mercury Research, a PC component market research firm, the market for high-end graphics memory is expected to grow by 42 percent next year, from $1.1 billion in 2005 to $1.5 billion in 2006.
