Memory
GDDR5 – Vividly Vibrant
Enabling the Most Advanced 3D Graphics
Samsung's GDDR5
memory – the fastest graphics memory in volume production today
– delivers a peak bandwidth of up to 28 GB/second. OEMs are able
to save power, space and cost for their graphics board designs,
while gaining outstanding performance for 3D and other intense
graphics applications. Just 16 Samsung 2 Gb GDDR5 chips can be
combined to provide a density of 4 GBs. Samsung GDDR5 provides
the most reliable and highest performing solution for the widest
array of high-end graphic applications – from storage devices,
digital TVs, set-top boxes and networking equipment to high-end
computers, gaming systems, workstations and graphics cards.
Performance Increasing Demand
Samsung GDDR5 is a hyper-synchronous,
double data rate DRAM, operating at data clock speeds up to
3.5 GHz and delivering data at up to 7.0 Gb/second. These advanced
chips enable graphics card suppliers to push the limits for
graphics excellence, providing a rich immersive experience for
gamers and enthusiasts alike. With the graphics capabilities
of PCs expanding rapidly - advanced graphics memory is making
possible of a much more lifelike recreation of images at blistering
speed, fueling even greater demand for GDDR5.
GDDR5 Features
GDDR5 supports data rates up to 7
Gbps, with a data clock speed of 3.5GHz (and an external clock
speed of 1.75 GHz), typically operating at 1.5V but also supporting
1.35V for ever lower power consumption. Samsung provide GDDR5
densities from 1 Gb to 2 Gb which help build a wide spectrum
of buffer solutions for graphics cards ranging from 256 MB to
8 GB. Further, our memory components are lead free and halogen
free, underscoring our ongoing support for eco-friendly solutions.
Advanced Features

Hardware Technology
Keeping up with Market Demand
Hardware technology is rapidly evolving,
and with it, the memory needed to support advanced 3D graphics.
Samsung GDDR5
offers workstation designers and other graphics-oriented users
a performance level of 5.0Gbps per pin, which represents an
increase of more than 200% over GDDR3 and 500% more than gDDR2.
By using the most advanced graphics memory, OEMs can enhance
their competitive advantage by offering incredibly products
providing richly textured imagery with lifelike movements.
Samsung has
been not only meeting the needs of the graphics market with
its GDDR5, but continuing to push the technology envelope –
in conjunction with its customers – to deliver the best graphics-enabled
3D products available.
