SAPPHIRE Technology has just announced a new graphics card in its HD 7000 series – the SAPPHIRE HD 7870 XT with Boost. Like the other cards in the HD 7000 series, the new card is based on the highly acclaimed Graphics Core Next architecture from AMD.

The SAPPHIRE HD 7870 XT with Boost delivers a new price:performance point to the series. It is based on AMD’s Tahiti architecture with its 256-bit memory interface, and 1536 stream processors and 96 Texture units, unlike the remainder of the HD 7800 series that uses the Pitcairn architecture. Configured with 2GB of high speed GDDR5 memory running at 1500 MHz (6GHz effective) the SAPPPHIRE HD 7870 XT has a core clock of 925MHz which dynamically rises to 975MHz with PowerTune Boost, AMDs dynamic performance enhancement for games.

This new model also features SAPPHIRE’s latest Dual-X cooler technology, with its graduated heatpipes and two aerofoil fans with dust repelling bearings for efficient cooling and low noise operation. Output configuration is Dual Link DVI-I (supporting VGA with dongle supplied), HDMI and two mini-DisplayPorts, allowing a wide range of monitor types to be connected. AMD’s multi-monitor SLS technology, Eyefinity is supported.

For enthusiasts wishing to maximise performance of this graphics card, the latest version of the SAPPHIRE overclocking tool, TriXX supports this technology and is available free to download from the SAPPHIRE website. SAPPHIRE TriXX allows tuning of GPU voltage as well as core and memory clocks, whilst continuously displaying temperature. Manual control of fan speed is supported, as well as user created fan profiles and the ability to save up to four different performance settings.
