AMD Radeon 550X: specs and benchmarks

AMD Radeon 550X

Summary

AMD started Radeon 550X sales 27 March 2019. This is GCN 4.0 architecture desktop card based on 14 nm manufacturing process and primarily aimed at gamers. 2 GB of GDDR5 memory clocked at 7 GHz are supplied, and together with 128 Bit memory interface this creates a bandwidth of 112.0 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 5.36 percent of a leader's which is NVIDIA GeForce RTX 3080 Ti.
