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

7.76%

of a leader's which is NVIDIA GeForce RTX 3090 Ti.
