The Radeon R7 M265 was a mobile graphics chip by AMD, launched on May 20th, 2014. Built on the 28 nm process, and based on the Topaz graphics processor, in its Topaz XT variant, the chip supports DirectX 12. This ensures that all modern games will run on Radeon R7 M265. The Topaz graphics processor is an average sized chip with a die area of 125 mm² and 1,550 million transistors. It features 384 shading units, 24 texture mapping units, and 8 ROPs. AMD has paired 2,048 MB DDR3 memory with the Radeon R7 M265, which are connected using a 64-bit memory interface. The GPU is operating at a frequency of 900 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. Rather it is intended for use in laptop/notebooks and will use the output of the host mobile device. Radeon R7 M265 is connected to the rest of the system using a PCI-Express 3.0 x8 interface.
