AMD has paired 2,048 MB GDDR5 memory with the FirePro V5900, which are connected using a 256-bit memory interface. It features 512 shading units, 32 texture mapping units, and 32 ROPs.
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 V5900 to reach the product's target shader count. The Cayman graphics processor is a large chip with a die area of 389 mm² and 2,640 million transistors. Built on the 40 nm process, and based on the Cayman graphics processor, in its Cayman LE WS variant, the card supports DirectX 11.2. The FirePro V5900 was a professional graphics card by AMD, launched on May 24th, 2011.
