The Radeon HD 7950 Mac Edition is a high-end graphics card by AMD, launched in March 2013. Built on the 28 nm process, and based on the Tahiti graphics processor, in its Tahiti PRO variant, the card supports DirectX 11.2. The Tahiti graphics processor is a large chip with a die area of 352 mm² and 4,313 million transistors. Unlike the fully unlocked Radeon HD 7970, which uses the same GPU but has all 2048 shaders enabled, AMD has disabled some shading units on the Radeon HD 7950 Mac Edition to reach the product's target shader count. It features 1792 shading units, 112 texture mapping units and 32 ROPs. AMD has placed 3,072 MB GDDR5 memory on the card, which are connected using a 384-bit memory interface. The GPU is operating at a frequency of 800 MHz, memory is running at 1250 MHz.
We recommend the AMD Radeon HD 7950 Mac Edition for gaming with highest details at resolutions up to, and including, 1920x1080.
Being a dual-slot card, the AMD Radeon HD 7950 Mac Edition draws power from 2x 6-pin power connectors, with power draw rated at 200 W maximum. Display outputs include: 1x DVI, 1x HDMI, 2x mini-DisplayPort. Radeon HD 7950 Mac Edition is connected to the rest of the system using a PCIe 3.0 x16 interface. The card measures 279 mm in length, and features a dual-slot cooling solution. Its price at launch was 449 US Dollars.
