Hynix this week double-dipped into the record books by introducing the world's first and fastest 1 Gigabit GDDR5 graphics DRAM operating at 7Gb/s, a 40 percent improvement over 5Gb/s GDDR5. The new memory is built using a 54nm process and can process up to 28GB/s with a 32-bit I/O, the company claims. On a 512-bit memory bus, bandwidth should reach as high as 448GB/s.

In addition to speed, Hynix also emphasized power consumption. The new memory requires just 1.35V as opposed to 1.5V inherent in previous generation GDDR5 memory. This means that the improved GDDR5 not only bodes well for future high performance videocards, but the potential for lower heat and longer battery life could also be a boon for notebooks.Hynix says its 1Gb GDDR5 graphics memory meets the JEDEC standard and plans to start volume production in the first half of 2009.
