The Radeon E9171 MCM was a mobile graphics chip by AMD, launched on October 3rd, 2017. Built on the 14 nm process, and based on the Lexa graphics processor, in its Lexa MCM Pro variant, the chip supports DirectX 12. This ensures that all modern games will run on Radeon E9171 MCM. The Lexa graphics processor is an average sized chip with a die area of 103 mm² and 2,200 million transistors. Unlike the fully unlocked Radeon 550X 640SP, which uses the same GPU but has all 640 shaders enabled, AMD has disabled some shading units on the Radeon E9171 MCM to reach the product's target shader count. It features 512 shading units, 32 texture mapping units, and 16 ROPs. AMD has paired 4 GB GDDR5 memory with the Radeon E9171 MCM, which are connected using a 128-bit memory interface. The GPU is operating at a frequency of 1124 MHz, which can be boosted up to 1219 MHz, memory is running at 1500 MHz (6 Gbps effective).
Its power draw is rated at 40 W maximum. 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 E9171 MCM is connected to the rest of the system using a PCI-Express 3.0 x8 interface.
