The Sapphire Radeon HD 7970 6GB TOXIC Editions is clocked at 1050MHz by default and can go up to 1100MHz and a 6000MHz memory clock with the help of PowerTune Dynamic Boosts. The core clock is further boost to 1200MHz and 6400MHz of memory clock by using Sapphire’s Lethal Boost button, all you have to do is push that button to unleash its power.

Another cool feature found in the Radeon HD 7970 TOXIC 6GB is the Lethal Power Suite. This contains premium design features such as 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.)

The Sapphire HD 7970 6GB Toxic Edition is cooled by Sapphire’s very own Vapor-X technology. You can see the signage of Vapor-X at the back the graphics card. But the Vapor-X in the HD 7970 Toxic Edition features a new vapor chamber custom-designed for this model only. Four heat pipes carry the heat and is being dispersed by two 90mm fan. The two 90mm fans features aerofoil blades and dust repelling bearings. It also has an onboard LED indicator (PCB Temperature LED) so that users can easily monitor the graphics card’s temperature.

The Sapphire HD 7970 6GB Toxic Edition supports all latest demands of multi-screen applications multi-threaded Application Acceleration with stream processing, fast HDMI support for high resolution and stereoscopic 3D displays and all the Direct Compute features incorporated in the latest operating systems. But unlike other graphics card, this one can handle multi-screen setup with the highest possible settings.
