Samsung Electronics announced over the weekend that it has
increased the data transfer speed on its extremely fast GDDR4 (Graphics Double
Data Rate, version 4) graphics memory. The South Korean electronics giant
claims that it has increased speeds by two-thirds.
Using 80-nanometer production technology, the 4Gb/s (2.0GHz)
is 66 percent faster than today’s fastest commercially available memory – the
2.4Gb/s GDDR4. The new 4Gb/s graphics memory, offered in 512Mb density, has a
32-bit data bus configuration. GDDR4 uses JEDEC-approved standards for signal
noise reduction to help attain the highest possible speed.
“Our new GDDR4 memory will add even more zip in video
applications, making gaming, computer-aided design and video editing faster
than ever before,” said Mueez Deen, marketing director, graphics memory,
Samsung Semiconductor, Inc. “This will enable ultra-smooth movements in
animation and make games incredibly realistic, resulting in a truly immersive
user experience,” he added.
Samsung cites analyst expectations for GDDR4 to
significantly boost demand for high-performance graphics memory over the next
12-18 months. The company said that it will begin customer sampling of its new
chips this month.
Most video cards on the market today from NVIDIA and ATI are
still using GDDR3, including solutions inside the Xbox 360 and PlayStation 3.
GDDR4 memory thus far has seen limited use in recent high-end cards
from ATI, and is expected to be paired with the upcoming R600 GPU.
