SAPPHIRE HD 7970 6GB TOXIC Edition – Fastest GPU Ever!
The SAPPHIRE HD 7970 6GB TOXIC Edition is based on the latest HD 7970 GHz Edition GPU from AMD, but features a massive overclock and an insane 6GB of GDDR5 memory. Its unique 6GB frame buffer is a World first for a consumer graphics card and makes the TOXIC Edition ideally suited to multi-screen gaming as well as providing the extra memory required for demanding professional applications such as content creation, video editing or rendering.
Performance is also World leading. By default, the HD 7970 6GB TOXIC Edition runs at 1050 MHz and dynamic boosts to 1100 MHz on the engine with the memory clock at 6000 MHz effective. By pressing the new SAPPHIRE exclusive Lethal Boost Button, the beast is unleashed, boosting the core clock speed to 1100 MHz with dynamic boost to an industry first of 1200 MHz on the engine while the memory is further overclocked to 6400 MHz Effective. We checked around and couldn’t find this card for sale online today, but rumor has it that the SAPPHIRE HD 7970 6GB TOXIC Edition will cost around $680.
This astonishing performance is achieved partly as a result of a completely new power control system developed by SAPPHIRE the Lethal Power Suite. The Lethal Power suite consists of many premium design features. These include 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 fast and stable. (The double sided Black Diamond Choke design reduces the temperature around the power design portion by 40 degree Celsius in lab test when compared to the reference PCB design.) Cooling a card with such extreme performance demands a special solution and the SAPPHIRE HD 7970 6GB TOXIC Edition has it with a new implementation of SAPPHIREs World acclaimed Vapor-X technology. 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.
