The Radeon 550 was an entry-level graphics card by AMD, launched on April 20th, 2017. 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 550. 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 550 to reach the product's target shader count. It features 512 shading units, 32 texture mapping units, and 16 ROPs.
