Seoul, Korea – February 12, 2009 – Samsung Electronics Co., Ltd., the world
graphics memory, announced today that it has begun mass producing GDDR5
graphics memory using 50-nanometer class process technology.
„With our launch of GDDR5 chips in the beginning of 2009 we satisfy the
increasing demand for higher performance graphics memory in PCs, graphic
cards and game consoles,“ said Gerd Schauss, Director of Memory Marketing,
Samsung Semiconductor Europe. „The advanced memory performance of the GDDR
series will thus upgrade the gaming experience across all platforms.“
Designed to support a maximum data transfer speed of 7.0Gbps (gigabits per
second), Samsung’s GDDR5 will render more life-like (3D) imaging with a
maximum 28GB/s (gigabytes per second) bandwidth, which is more than twice
that of the previous fastest graphics memory bandwidth of 12.8GB/s for
GDDR4. The ultra-fast processing speed is equivalent to transferring
nineteen 1.5GB DVD resolution movies in one second. The high image
processing speed of the GDDR5 also supports the latest data formats
(Blu-ray and full HD).
Unlike GDDR4, which processes data and images using the strobe-and-clock
technique, the processing speed of the GDDR5 is much faster because it
operates with a free-running clock that does not require the data
read/write function to be synchronized to the operations of the clock.
By adopting 50nm class technology, Samsung expects production efficiency to
rise 100 percent over 60nm class technology. In addition, Samsung’s GDDR5
operates at 1.35 volts (V), which represents a 20 percent reduction in
power consumption compared to the 1.8V at which GDDR4 devices operate.
Now available in a 32Megabit (Mb) x32 configuration and also configurable
as a 64Mb x16 device, Samsung expects GDDR5 to account for over 20 percent
of the total graphic memory market in 2009. The company also said it
plans to expand the 50-nm process technology throughout its graphics memory
line-up this year.
