Radeon RX 550 vs Radeon RX 6400 comparison

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

Our database shows that the Radeon RX 6400 has a significantly higher core clock speed. This is the frequency at which the graphics core is running at. While not necessarily an indicator of overall performance, this metric can be useful when comparing two GPUs based on the same architecture. In addition, the Radeon RX 6400 also has a significantly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

Furthermore, the spec sheet for both these GPUs show that they both have the same amount of memory at 4 GiB. Lots of memory is good when playing at high resolutions or with many monitors.

In addition, the Radeon RX 550 has a slightly lower TDP at 50 W when compared to the Radeon RX 6400 at 53 W. TDP (Thermal Design Power) measures total heat output from the chip.

According to the results of the hardwareDB benchmark utility, the Radeon RX 6400 is faster than the Radeon RX 550.
