Qimonda and Advantest Develop Test Hardware for GDDR5

Samsung Electronics has already showcased GDDR4 chips operating at 4GHz, two times higher compared to currently available 2.0GHz GDDR3 and GDDR4 memory devices. Originally it was estimated that GDDR4 would scale to about 2.8GHz in 2007 and in 2008 the GDDR5 would kick off at 3.5GHz to reach 4GHz speeds in 2009. However, Samsung’s new chips may cause the industry to revise technology roadmap, especially keeping in mind that Samsung has been able to clock the GDDR4 at 3.20GHz about a year ago.
