DRAM major, Hynix has announced the depelopment of 7 GT/s GDDR5 memory chips for use by the visual-computing industry. These chips are built on the company's 54nm silicon fabrication technology.

The 1 Gb (128 MB) chips labelled H5GQ1H24AFR operate at the fastest speeds so far: 7 Gbps (or GT/s), which is a 40% boost in speeds compared to the older 5 GT/s chips already in production. The chip handles up to 28 GB of data per second across a 32-bit wide interface. The incorporation of new fab. processes also means reduced power consumption at 1.35V power supply. The JEDEC-standard 1Gb GDDR5 graphics DRAM chip targets high-end applications such as game consoles and graphics cards. The company will commence volume production in the first half of 2009.
