"The key differences between the Sapphire Radeon HD 4870 Toxic and the normal Sapphire Radeon HD 4870 or any of the other HD 4870 graphics cards from other AIBs is the factory overclock and the graphics card cooler. The Sapphire Radeon HD 4870 Toxic arrives with a 780MHz core clock and 1000MHz memory clock. This is in comparison to the reference specification for the RV770XT (Radeon HD 4870) that calls for a 750MHz core clock and 900MHz GDDR5 memory clock."
