AMD Radeon RX 550X: specs and benchmarks

VS

Summary

AMD started Radeon RX 550X sales 16 December 2018. This is a desktop graphics card based on a GCN 4.0 architecture and made with 14 nm manufacturing process. It is primarily aimed at gamer market. 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 5.80% of a leader's which is NVIDIA GeForce RTX 4090.
