The Radeon RX 550X was a graphics card by AMD, launched on December 16th, 2018. Built on the 14 nm process, and based on the Lexa graphics processor, in its Lexa PRO variant, the card supports DirectX 12. This ensures that all modern games will run on Radeon RX 550X. 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 RX 550X 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 RX 550X, 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 1183 MHz, memory is running at 1500 MHz (6 Gbps effective).
Being a dual-slot card, the AMD Radeon RX 550X does not require any additional power connector, its power draw is rated at 50 W maximum. Display outputs include: 1x DVI, 1x HDMI 2.0b, 1x DisplayPort 1.4a. Radeon RX 550X is connected to the rest of the system using a PCI-Express 3.0 x8 interface. The card measures 145 mm in length, and features a dual-slot cooling solution.
