The German memory manufacturer Qimonda, chosen by AMD as a supplier of GDDR5 for the first Radeon HD 4870s, should start producing this high performance memory in 58nm versus the current 70nm next year enabling to reduce production costs. Moreover, 128 MB sized chips should soon be produced in volume in the second half of this year.

For comparison, Hynix already offers 128 MB chips of GDDR5 engraved in 66nm and Samsung already aims for a frequency of 3 GHz for its GDDR5, which corresponds to a bandwidth of 192 GB /s with a 256 bit standard width memory controller.

With an ambitious objective of a 30% GDDR market share, the memory division of the Infineon group indeed wants to keep up. They skipped over GDDR4, which it’s true did not have much success, in order to concentrate on the development of GDDR5.
