Hynix introduced the first 1 Gigabit (128MB) GDDR5 DRAM chips.
Each 32-bits chip is able to operate at 5Gbps bandwidth and to process up to 20 GB/s of data. Depending on the graphic memory bus, data speed will evolve, from 160GB/s on a 256-bits bus, to 320GB/s on a 512-bits bus. With the latest memory bus, such chips will allow 2GB of VRAM to be managed on graphic cards.
If some users might think that this is a lot of memory for nothing, they should although consider that GPUs are currently used by OS X as well as Vista to boost display and rendering of both OSes. In addition, as the size of LCD panels will not keep increasing at a steady state, the future evolution in this field will be driven by higher resolution, always more
