Samsung is building 4GB modules with four layers of 8-gigabit cores, but plans on introducing 8GB products with eight stacks by the end of the year. The company said that "by specifying [the chips] in graphics cards, designers will be able to enjoy a space savings of more than 95 percent compared to GDDR5 DRAM." That means NVIDIA and AMD can build more size-efficient cards that run cooler and faster -- and therefore play Crysis more smoothly. The 4GB chips Samsung is building now could end up in next-gen consumer cards, while 8GB models are more likely to end up in high-end NVIDIA Kepler and AMD FIrePro workstations.
