X-bit Labs writes Qimonda can now deliver GDDR5 memory with clockspeeds of up to 4.5GHz:
“Qimonda was the first to announce samples of GDDR5 back in November 2007. We have proven the technology and we can deliver in volume production to the market today,” said Glen Haley, communications director of Qimonda in North America, in an interview with X-bit labs web-site.
Presently Qimonda has 512Mb (16Mx32) GDDR5 chips at 3.60GHz, 4.0GHz and 4.50GHz clock-speeds in PG-TFBGA-170 packages in production. It is interesting to note that current-generation GDDR3 chips from Qimonda use PG-TFBGA-136 packing, which means that GDDR5 has more pins and requires more complex print-circuit boards of graphics cards.
It is projected that GDDR5 will play a substantial role in the next round of war between the leading designers of graphics processing units (GPUs) because it can double bandwidth available for graphics chips. Unfortunately, the price of GDDR5 memory from Qimonda is unclear. But while Qimonda does not unveil the exact pricing, it is likely that GDDR5 will be more expensive than GDDR3 and GDDR4, at least initially.
