The Radeon Instinct MI8 was a professional graphics card by AMD, launched on December 12th, 2016. Built on the 28 nm process, and based on the Fiji graphics processor, in its Fiji XT variant, the card supports DirectX 12. The Fiji graphics processor is a large chip with a die area of 596 mm² and 8,900 million transistors. It features 4096 shading units, 256 texture mapping units, and 64 ROPs. AMD has paired 4 GB HBM memory with the Radeon Instinct MI8, which are connected using a 4096-bit memory interface. The GPU is operating at a frequency of 1000 MHz, memory is running at 500 MHz (1000 Mbps effective).
Being a dual-slot card, the AMD Radeon Instinct MI8 draws power from 1x 8-pin power connector, with power draw rated at 175 W maximum. This device has no display connectivity, as it is not designed to have monitors connected to it. Radeon Instinct MI8 is connected to the rest of the system using a PCI-Express 3.0 x16 interface. The card measures 152 mm in length, 111 mm in width, and features a dual-slot cooling solution.
