Sapphire is introducing its HD 7970 6GB Toxic Edition graphics card.
Based on the AMD Radeon HD 7970 GHz Edition GPU, its huge 6GB frame buffer makes it perfect for extra memory required for demanding professional applications such as content creation, video editing, and rendering.
In default mode, the HD 7970 6GB Toxic Edition runs at 1050MHz and dynamic boosts to 1100MHz on the engine with the memory clocking in at 6000MHz. At a single push of the Sapphire exclusive Lethal Boost Button, core clock speeds are raised to 1100MHz with dynamic boost to 1200MHz on the engine while the memory is further overclocked to 6400MHz.
Performance is made possible with the aid of a new power control system developed by Sapphire called the Lethal Power Suite. It consists of premium design features including a new 8 phase power design for the GPU VDDC, with an additional one phase each for VDDCI and MVDD. The design uses a brand new double sided Black Diamond Choke for the first time, as well as DirectFET technology and all on a 12 layer PCB to ensure the board runs stably and efficiently.
Additionally, the Vapor-X cooler on the Toxic Edition is based on a new vapor chamber designed especially for this model. Heat is carried away by four heatpipes (2 x 8mm plus 2 x 6mm), and finally dispersed by two 90mm fan with aerofoil blades and dust repelling bearings. Another new feature is the PCB Temperature LED, which is a built-in on-board LED for users to monitor the PCB temperature.
The Sapphire HD 7970 6GB Toxic Edition is a limited edition graphics card that will be available to order from Sapphire etailers and retailers starting 17th July 2012.
