AMD Radeon RX 550X: specs and benchmarks

AMD Radeon RX 550X

Summary

AMD started Radeon RX 550X sales 16 December 2018. This is GCN 4.0 architecture desktop card based on 14 nm manufacturing process and primarily aimed at gamers. 4 GB of GDDR5 memory clocked at 6 GHz are supplied, and together with 128 Bit memory interface this creates a bandwidth of 96 GB/s.

Compatibility-wise, this is dual-slot card attached via PCIe 3.0 x8 interface. Its manufacturer default version has a length of 145 mm. No additional power connector is required, and power consumption is at 50 Watt.

It provides poor gaming and benchmark performance at 8.14 percent of a leader's which is AMD Radeon RX 6900 XT.
