The Radeon R9 M375 is a mobile graphics chip by AMD, launched in May 2015. Built on the 28 nm process, and based on the Tropo graphics processor, in its Tropo XT2 variant, the chip supports DirectX 12. Even though it supports DirectX 12, the feature level is only 11_1, which can be problematic with newer DirectX 12 titles. The Tropo graphics processor is an average sized chip with a die area of 123 mm² and 1,500 million transistors. It features 640 shading units, 40 texture mapping units, and 16 ROPs. AMD has paired 2,048 MB DDR3 memory with the Radeon R9 M375, which are connected using a 128-bit memory interface. The GPU is operating at a frequency of 1000 MHz, which can be boosted up to 1015 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 R9 M375 is connected to the rest of the system using a PCI-Express 3.0 x16 interface.
