Radeon RX 550X vs Radeon RX 6400 specs and performance

According to the hardwareDB Benchmark, the Radeon RX 6400 GPU is faster than the Radeon RX 550X in gaming.

Our database shows that the Radeon RX 6400 has a significantly higher core clock speed. The core clock speed (or base speed) is the frequency at which the GPU core runs. This metric makes sense when comparing GPUs of a similar architecture or generation. In addition, the Radeon RX 6400 also has a significantly higher boost clock speed. This is a frequency that can be reached if the GPU is cooled sufficiently and has enough power.

As stated by the manufacturer, they both have the same amount of memory at 4 GiB. If you're planning at playing games at high resolutions with high-quality textures, you will need a lot of memory.

In addition, the Radeon RX 550X has a slightly lower TDP at 50 W when compared to the Radeon RX 6400 at 53 W. This is not a measure of performance, but rather the amount of heat generated by the chip when running at its highest speed.

In conclusion, all specs and GPU benchmarks considered, will recommend the Radeon RX 6400 over the Radeon RX 550X.
