The Radeon R9 390 is a performance graphics card by AMD, launched in June 2015. Built on the 28 nm process, and based on the Grenada graphics processor, in its Grenada PRO variant, the card supports DirectX 12.0. The Grenada graphics processor is a large chip with a die area of 438 mm² and 6,200 million transistors. Unlike the fully unlocked Radeon R9 390X, which uses the same GPU but has all 2816 shaders enabled, AMD has disabled some shading units on the Radeon R9 390 to reach the product's target shader count. It features 2560 shading units, 160 texture mapping units and 64 ROPs. AMD has placed 8,192 MB GDDR5 memory on the card, which are connected using a 512-bit memory interface. The GPU is operating at a frequency of 1000 MHz, memory is running at 1500 MHz.
Being a dual-slot card, the AMD Radeon R9 390 draws power from 1x 6-pin + 1x 8-pin power connectors, with power draw rated at 275 W maximum. Display outputs include: 2x DVI, 1x HDMI, 1x DisplayPort. Radeon R9 390 is connected to the rest of the system using a PCI-Express 3.0 x16 interface. The card measures 275 mm in length, and features a dual-slot cooling solution. Its price at launch was 329 US Dollars.
