The Radeon HD 7970M was a mobile graphics chip by AMD, launched on April 24th, 2012. Built on the 28 nm process, and based on the Wimbledon graphics processor, in its Wimbledon XT variant, the chip supports DirectX 12. Even though it supports DirectX 12, the feature level is only 11_1, which can be problematic with newer DirectX 12 titles. The Wimbledon graphics processor is an average sized chip with a die area of 212 mm² and 2,800 million transistors. It features 1280 shading units, 80 texture mapping units, and 32 ROPs. AMD has paired 2,048 MB GDDR5 memory with the Radeon HD 7970M, which are connected using a 256-bit memory interface. The GPU is operating at a frequency of 850 MHz, memory is running at 1200 MHz (4.8 Gbps effective).
Being a mxm module card, the AMD Radeon HD 7970M does not require any additional power connector, its power draw is rated at 100 W maximum. This device has no display connectivity, as it is not designed to have monitors connected to it. Rather it is intended for use in laptop/notebooks and will use the output of the host mobile device.
