The Radeon E9172 MXM is a graphics card by AMD, launched in October 2017. Built on the 14 nm process, and based on the Lexa graphics processor, in its E9170 variant, the card supports DirectX 12.0. 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 E9172 MXM to reach the product's target shader count. It features 512 shading units, 32 texture mapping units and 16 ROPs. AMD has placed 2,048 MB GDDR5 memory on the card, which are connected using a 64-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.
Being a mxm module card, the AMD Radeon E9172 MXM does not require any additional power connector, its power draw is rated at 35 W maximum. This device has no display connectivity, as it is not designed to have monitors connected to it.
