Performance Rating

The Radeon HD 7970M X2 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. Radeon HD 7970M X2 combines two graphics processors to increase performance. It features 1280 shading units, 80 texture mapping units, and 32 ROPs, per GPU. AMD has paired 4 GB GDDR5 memory with the Radeon HD 7970M X2, which are connected using a 256-bit memory interface per GPU (each GPU manages 2,048 MB). The GPU is operating at a frequency of 850 MHz, memory is running at 1200 MHz (4.8 Gbps effective).
