Graphics Memory
General Description
Since the world¡¯s first Graphics DDR SDRAM was introduced in 1999, Hynix has played a leadership role in the Graphics memory market by offering cost effective and high performance products. Hynix¡¯s newly introduced 44nm 2Gb GDDR5 offers designers 7Gbps speed (bandwidth of 28GB/sec with 32 I/O) required for high end graphics. In addition to both improved speed and higher density, the power consumption on the 2Gb GDDR5 is significantly reduced since it operates on 1.35V power supply. This results in an estimated 20% reduction in power consumption compared to the 1.5V products meeting Hynix¡¯s goal of developing eco-friendly products. The 2Gb GDDR5 will meet the needs of high-end desktop and notebook graphics applications. It will also be suitable in super computers designed with a General Purpose GPU architecture, where the 2Gb GDDR5 will serve as high bandwidth memory to the GPU. Hynix has maintained its leadership in graphics memory with the world¡¯s first 66nm 1Gb GDDR5 in 2007 followed by the 54nm 1Gb GDDR5 in 2008 and 44nm 2Gb GDDR5 in early 2010 Hynix also supports GDDR3, DDR3 and DDR2 products for performance and mainstream market. Hynix will provide more values for customers¡¯ success with the higher performance, quality and technology leadership.
