Sapphire Expands Its HD 7790 Series with a 2GB Model
Sapphire has just added a 2GB model to its existing lineup of Radeon HD 7790 graphics cards.
Like other members of the HD 7790 series, the Sapphire HD 7790 2GB OC is based on the latest Bonaire chipset featuring AMD's GCN (Graphics Core Next) architecture. Factory overclocked with core and memory clocks of 1050MHz and 6400MHz respectively, the card comes fused with the AMD PowerTune technology, and features a new cooler design which uses a dual heatpipe system and a single aerofoil section fan assembly with dust repelling bearings for maximum efficiency and reliability.
Also included is Sapphire's proprietary integration of the metal backplate into the cooling system, which cools the memory chips on the reverse side of the PCB, and helps with the 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 degrees Celsius.
The card supports the FleX feature by Sapphire, allowing 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 series is shipping now and is available through Sapphire’s established etail and retail partners. Purchasers will also receive a voucher for a free copy of the highly acclaimed BioShock Infinite from participating retailers.
