The Radeon HD 6970M Mac Edition was a graphics card by AMD, launched in August 2011. Built on the 40 nm process, and based on the Blackcomb graphics processor, in its Blackcomb XT variant, the card supports DirectX 11.2. The Blackcomb graphics processor is an average sized chip with a die area of 212 mm² and 1,700 million transistors. Unlike the fully unlocked Radeon HD 6990M, which uses the same GPU but has all 1120 shaders enabled, AMD has disabled some shading units on the Radeon HD 6970M Mac Edition to reach the product's target shader count. It features 960 shading units, 48 texture mapping units and 32 ROPs. AMD has placed 2,048 MB GDDR5 memory on the card, which are connected using a 256-bit memory interface. The GPU is operating at a frequency of 680 MHz, memory is running at 900 MHz.
Being a mxm module card, the AMD Radeon HD 6970M Mac Edition does not require any additional power connector, its power draw is rated at 75 W maximum. This device has no display connectivity, as it is not designed to have monitors connected to it.
