The Radeon RX 550 Mobile was a mobile graphics chip by AMD, launched on July 2nd, 2017. Built on the 14 nm process, and based on the Lexa graphics processor, in its Lexa PRO variant, the chip supports DirectX 12. This ensures that all modern games will run on Radeon RX 550 Mobile. The Lexa graphics processor is an average sized chip with a die area of 103 mm² and 2,200 million transistors. It features 640 shading units, 40 texture mapping units, and 16 ROPs. AMD has paired 2,048 MB GDDR5 memory with the Radeon RX 550 Mobile, which are connected using a 128-bit memory interface. The GPU is operating at a frequency of 1100 MHz, which can be boosted up to 1287 MHz, memory is running at 1500 MHz (6 Gbps effective).
Its power draw is rated at 50 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 RX 550 Mobile is connected to the rest of the system using a PCI-Express 3.0 x8 interface.
