AMD Radeon RX 550 Graphics Cards: Price List

AMD designed the Radeon RX 550 with its Polaris 12 core (code-named Lexa) as an inexpensive solution for low-end gaming. The GPU sports 640 EUs in total, but two of its Compute Units are disabled, leaving 512 Stream processors active. The RX 550 comes equipped with either 2GB or 4GB of GDDR5 memory at 7 Gb/s, which communicates over an aggregate 128-bit interface. In terms of performance, the RX 550 is decidedly entry-level, competing against Nvidia's GeForce GT 1030 at HD resolutions. It typically sells for somewhere between $80 and $100.
