Samsung Electronics Co.,
Ltd., the world leader in advanced memory technology and the leading producer
of high-end graphics memory, announced today that it has begun mass producing
GDDR5 graphics memory using 50-nanometer class process technology.
“Our early 2009 introduction of GDDR5 chips will help us to meet the
growing demand for higher performance graphics memory in PCs, graphic cards
and game consoles,” said Mueez Deen, director, mobile and graphics memory,
Samsung Semiconductor, Inc. “Because GDDR5 is the fastest and highest
performing memory in the world, we're able to improve the gaming experience
with it across all platforms,” he added.
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 GDDR5 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.
