The Radeon R7 250 was a graphics card by AMD, launched in October 2013. Built on the 28 nm process, and based on the Cape Verde graphics processor, in its Cape Verde PRO2 variant, the card supports DirectX 12.0. The Cape Verde graphics processor is an average sized chip with a die area of 123 mm² and 1,500 million transistors. Unlike the fully unlocked Radeon HD 7770 GHz Edition, which uses the same GPU but has all 640 shaders enabled, AMD has disabled some shading units on the Radeon R7 250 to reach the product's target shader count. It features 512 shading units, 32 texture mapping units and 16 ROPs. AMD has placed 1,024 MB DDR3 memory on the card, which are connected using a 128-bit memory interface. The GPU is operating at a frequency of 925 MHz, memory is running at 900 MHz.
Being a single-slot card, the AMD Radeon R7 250 does not require any additional power connector, its power draw is rated at 55 W maximum. Display outputs include: 1x DVI, 1x HDMI, 1x DisplayPort. Radeon R7 250 is connected to the rest of the system using a PCI-Express 3.0 x16 interface. The card measures 168 mm in length, and features a single-slot cooling solution.
