Even though it supports DirectX 12, the feature level is only 11_1, which can be problematic with newer DirectX 12 titles. The Pitcairn graphics processor is an average sized chip with a die area of 212 mm² and 2,800 million transistors. It features 1280 shading units, 80 texture mapping units, and 32 ROPs. AMD has paired 2,048 MB GDDR5 memory with the Radeon HD 7870 GHz Edition, which are connected using a 256-bit memory interface. The GPU is operating at a frequency of 1000 MHz, memory is running at 1200 MHz (4.8 Gbps effective).
Being a dual-slot card, the AMD Radeon HD 7870 GHz Edition draws power from 2x 6-pin power connectors, with power draw rated at 175 W maximum. Display outputs include: 1x DVI, 1x HDMI, 2x mini-DisplayPort. Radeon HD 7870 GHz Edition is connected to the rest of the system using a PCI-Express 3.0 x16 interface. The card measures 241 mm in length, and features a dual-slot cooling solution. Its price at launch was 349 US Dollars.
