Sapphire has just added a 2 GB model to the recently
introduced HD 7790 series of graphics cards.
Like the other members of the series, the SAPPHIRE HD 7790 2
GB OC is based on the latest Bonaire chipset featuring the
graphics GCN (Graphics Core Next) architecture from AMD.
The SAPPHIRE HD 7790 2 GB OC Edition has 2 GB of the latest
DDR5 memory and is factory overclocked, with core clocks of
1050 MHz and memory clocks of 1600 MHz (6.4 GT/s effective).
Performance is optimized with the latest version of AMD's
The 2 GB board features a new cooler design, which uses a
dual heatpipe system and a single aerofoil section fan
assembly with dust repelling bearings. A SAPPHIRE original
feature is the integration into the cooling system of the
metal backplate which cools the memory chips on the reverse
side of the PCB and helps with PCB rigidity. A finned
heatsink attached to the backplate passes through the pcb
and extends into the airflow from the fan on the front side
of the card, enabling the airflow to carry away the heat
from the components on the back of the PCB and reducing
memory temperatures to as low as 13°C.
The SAPPHIRE HD 7700 series also supports working or gaming
with multiple monitors with AMD Eyefinity, now in its second
generation. The card has two DVI ports (DVI-I and DVI-D),
HDMI and a single DisplayPort output, supporting up to four
The model also supports the FleX feature, which allows three
digital displays to be connected to the DVI and HDMI outputs
and used in AMD Eyefinity mode without the need for an
external active adapter. All four outputs can be used in AMD
Eyefinity mode, but the fourth display must be a DisplayPort
monitor or connected with an active adapter.
The SAPPHIRE HD 7790 OC Edition can be installed in any PC
with a free x16 PCI-Express slot, and communication with the
host PC is optimised with the use of the latest high speed
PCI-Express Gen3.0 interface.
The SAPPHIRE HD 7790 OC is ready for Windows 8 with its
architecture designed for DirectX 11.1, OpenGL 4.2 and
OpenCL 1.2. This latest version of AMD's Graphics Core Next
(GCN) architecture also supports new fast HDMI features
(such as support for 4K resolution and full frame rate 1080p
stereoscopic support), DisplayPort 1.2 certification (with
support for Multi-Stream Transmission), and DDM Audio (which
adds supports for up to 6 simultaneous independent audio
streams). Video capabilities include native support for 3D
Blu-ray (MVC Codec), DivX decode and hardware encoding of
H.264 video via VCE.
The SAPPHIRE HD 7790 series is shipping now and is available
through SAPPHIRE's etail and retail partners. Purchasers
will also receive a voucher for a free copy of the 'BioShock
Infinite' from participating retailers.
