Radeon RX 480 vs Radeon RX 6400 benchmarks

For gaming, the Radeon RX 480 graphics card is better than the Radeon RX 6400 in our tests.

In our comparison, 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, the Radeon RX 480 has significantly more memory with 8 GiB of memory compared to 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 6400 has a significantly lower TDP at 53 W when compared to the Radeon RX 480 at 150 W. TDP (Thermal Design Power) measures total heat output from the chip.

In conclusion, all specs and GPU benchmarks considered, will recommend the Radeon RX 480 over the Radeon RX 6400.
