The FirePro D500 was a professional graphics card by AMD, launched on January 18th, 2014. Built on the 28 nm process, and based on the Tahiti graphics processor, in its Tahiti LE GL variant, the card supports DirectX 12. 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 FirePro D500 to reach the product's target shader count. It features 1536 shading units, 96 texture mapping units, and 32 ROPs. AMD has paired 3,072 MB GDDR5 memory with the FirePro D500, which are connected using a 384-bit memory interface. The GPU is operating at a frequency of 725 MHz, memory is running at 1270 MHz (5.1 Gbps effective). Being a dual-slot card, its power draw is rated at 274 W maximum. Display outputs include: 6x mini-DisplayPort 1.2, 1x SDI. FirePro D500 is connected to the rest of the system using a PCI-Express 3.0 x16 interface. The card measures 279 mm in length, and features a dual-slot cooling solution.
