The Radeon R9 380 OEM is a graphics card by AMD, launched in May 2015. Built on the 28 nm process, and based on the Antigua graphics processor, in its Antigua PRO variant, the card supports DirectX 12.0. The Antigua graphics processor is a large chip with a die area of 366 mm² and 5,000 million transistors. Unlike the fully unlocked Radeon R9 380X, which uses the same GPU but has all 2048 shaders enabled, AMD has disabled some shading units on the Radeon R9 380 OEM to reach the product's target shader count. It features 1792 shading units, 112 texture mapping units and 32 ROPs. AMD has placed 4,096 MB GDDR5 memory on the card, which are connected using a 256-bit memory interface. The GPU is operating at a frequency of 918 MHz, memory is running at 1375 MHz.
Being a dual-slot card, the AMD Radeon R9 380 OEM draws power from 2x 6-pin power connectors, with power draw rated at 190 W maximum. Display outputs include: 2x DVI, 1x HDMI, 1x DisplayPort. Radeon R9 380 OEM is connected to the rest of the system using a PCI-Express 3.0 x16 interface. The card measures 221 mm in length, and features a dual-slot cooling solution.
