Samsung Develops Faster GDDR4 Graphics Memory
Samsung announced today that it has developed the world?s fastest graphics memory – a GDDR4 graphics DRAM (dynamic random access memory) chip with much faster processing than an earlier version that Samsung led the industry in prototyping only four months ago.
Graphics memory, unlike main computer memory, is installed in desktop PCs, notebooks and workstations to manage huge volumes of video images simultaneously. Designed with 80-nanometer process technology, the device has a 12.8GB/sec processing speed, 30 percent faster than the previous prototype, which allows it to transfer the equivalent of up to six DVD-quality movies every second. The 512Mb GDDR4 graphics DRAM comes with 32 input/output pins, each of which transfers data at 3.2Gb/sec. In October, Samsung completed samples of a 256Mb GDDR4 that processed video (and accompanying audio) at 10 gigabytes per second.
