SAPPHIRE ships HD 4770
High
Performance graphics at a
mid-range price
SAPPHIRE
Technology, the leading
manufacturer and worldwide supplier of AMD/ATI based graphics solutions
is now shipping
the SAPPHIRE HD 4770 - a powerful midrange graphics card that brings
new levels
of graphics and video performance to enthusiasts on a budget.
The new
SAPPHIRE HD 4770 is the first card
in its class to use GDDR5 memory and is based on the first ever GPU
built in
40nm process technology. It uses the powerful graphics architectures
from the
ATI division of AMD, incorporating multi-purpose stream processing
units and
improved memory management architecture.
With 640
stream processors – twice as many
as previous generation mid-range cards - and core clock speed of
750MHz,
together with 512MB of GDDR5 memory clocked at 800MHz (3200MHz
effective), the
SAPPHIRE HD 4770 delivers stunning performance for gaming or image
rendering.
It delivers an outstanding computataional performance of 960Gflops,
memory
bandwidth of 51.2GB/s and texture fill rates of 24GTexels/s.
The new 40nm
core technology delivers all
of this with reduced power consumption, making the total power
requirement of
the card only 80Watts and typically less in operation as a result of
dynamic
power management. The first cards to market use a conventional two slot
fan
assisted cooler and offer dual DVI and TV-Out on the bracket, as well
as
support for HDMI (with Audio) over a dongle. SAPPHIRE
will be introducing additional models
- including some Special Editions - in the coming weeks.
Like the
previous generation, SAPPHIRE HD
4770 supports DirectX10.1 for enhanced rendering performance and
special lighting
effects now being implemented in the latest games. The SAPPHIRE HD 4770
series uses
the PCI-Express Gen2 interface, and features connectors for CrossFireX
bridge cables,
allowing two cards to be used together on a CrossFireX compatible
mainboard for
higher graphics performance.
SAPPHIRE
graphics cards in the HD 4000
series incorporate the latest ATI Avivo™ HD Technology for
enhanced Video
display. They feature a new generation of built in hardware UVD
(Unified Video
decoder) considerably reducing CPU load and delivering smooth decoding
of
Blu-ray™ and HD DVD content for both VC-1 and H.264 codecs,
as well as Mpeg
files. Integrated upscaling technology delivers the best quality DVD
video
images. With the latest drivers, the SAPPHIRE HD 4770 also offers ATI
Stream
processing for the acceleration of video transcoding and other
supported
applications.
SAPPHIRE HD
4000 series graphics cards are
Microsoft Windows Vista™ Premium certified and supported by
the ATI Catalyst®
suite of software, ensuring customers have ongoing access to software
updates
for performance, stability and added features.
