Today AMD announced the first commercial implementation of GDDR5 (Graphics Double Data Rate, version 5) memory in its forthcoming next generation of ATI Radeon graphics cards. The GPU performance in today's graphics cards is limited by the rate at which data can be moved on and off the graphics chip, which in turn is limited by the memory interface width and die size.
The higher data rates supported by GDDR5 is up to 5x that of GDDR3 and 4x that of GDDR4. A full six months after Samsung took the wraps off of GDDR5 memory, along comes word from AMD that the next-generation ATI Radeon graphics cards will boast said technology. Apparently AMD will be tapping Qimonda for its supply of GDDR5 modules, which should boost gaming performance as well as benefit stream processing, "where GPUs are applied to address complex, massively parallel calculations." As Hot Hardware points out, the release comes just weeks away from the rumored debut of the Radeon 4000 series, so if our deductive reasoning is sound, we'd surmise that the looming Radeon 4800 will indeed feature GDDR5.Read more at EngadgetNews.
