The Radeon R7 M370 is a graphics card by AMD, launched in May 2015. Built on the 28 nm process, and based on the Litho graphics processor, in its Litho XT variant, the card supports DirectX 12.0. The Litho graphics processor is a relatively small chip with a die area of only 77 mm² and 1,040 million transistors. It features 384 shading units, 24 texture mapping units and 8 ROPs. AMD has placed 4,096 MB GDDR5 memory on the card, which are connected using a 128-bit memory interface. The GPU is operating at a frequency of 900 MHz, which can be boosted up to 960 MHz, memory is running at 1150 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 M370 is connected to the rest of the system using a PCI-Express 3.0 x8 interface.
