The Radeon Pro Duo is a enthusiast-class professional graphics card by AMD, launched in April 2016. Built on the 28 nm process, and based on the Capsaicin graphics processor, in its Capsaicin XT variant, the card supports DirectX 12.0. The Capsaicin graphics processor is a large chip with a die area of 596 mm² and 8,900 million transistors. Radeon Pro Duo combines two graphics processors to increase performance. It features 4096 shading units, 256 texture mapping units and 64 ROPs per GPU. AMD has placed 8,192 MB HBM memory on the card, which are connected using a 4096-bit memory interface per GPU (each GPU manages 4,096 MB). The GPU is operating at a frequency of 1000 MHz, memory is running at 500 MHz.
Being a dual-slot card, the AMD Radeon Pro Duo draws power from 3x 8-pin power connectors, with power draw rated at 350 W maximum. Display outputs include: 1x HDMI, 3x DisplayPort. Radeon Pro Duo is connected to the rest of the system using a PCI-Express 3.0 x16 interface. The card measures 277 mm in length, and features a dual-slot cooling solution. Its price at launch was 1499 US Dollars.
