The Radeon R7 M260 was a graphics card by AMD, launched in June 2014. Built on the 28 nm process, and based on the Topaz graphics processor, in its Topaz XT variant, the card supports DirectX 12.0. The Topaz graphics processor is an average sized chip with a die area of 125 mm² and 3,100 million transistors. It features 384 shading units, 24 texture mapping units and 8 ROPs. AMD has placed 2,048 MB DDR3 memory on the card, which are connected using a 64-bit memory interface. The GPU is operating at a frequency of 940 MHz, which can be boosted up to 980 MHz, memory is running at 900 MHz.
Its power draw is not exactly known. This device has no display connectivity, as it is not designed to have monitors connected to it. Radeon R7 M260 is connected to the rest of the system using a PCI-Express 3.0 x8 interface.
