The FirePro V7900 was a professional graphics card by AMD, launched on May 24th, 2011. Built on the 40 nm process, and based on the Cayman graphics processor, in its Cayman PRO GL variant, the card supports DirectX 11.2. The Cayman graphics processor is a large chip with a die area of 389 mm² and 2,640 million transistors. Unlike the fully unlocked Radeon HD 6970, which uses the same GPU but has all 1536 shaders enabled, AMD has disabled some shading units on the FirePro V7900 to reach the product's target shader count. It features 1280 shading units, 80 texture mapping units, and 32 ROPs. AMD has paired 2,048 MB GDDR5 memory with the FirePro V7900, which are connected using a 256-bit memory interface. The GPU is operating at a frequency of 725 MHz, memory is running at 1250 MHz (5 Gbps effective).
Being a single-slot card, the AMD FirePro V7900 draws power from 1x 6-pin power connector, with power draw rated at 150 W maximum. Display outputs include: 4x DisplayPort 1.2. FirePro V7900 is connected to the rest of the system using a PCI-Express 2.0 x16 interface. The card measures 279 mm in length, 111 mm in width, and features a single-slot cooling solution.
