Radeon Vega 8 vs Radeon RX 6400 benchmarks

For gaming, the Radeon RX 6400 graphics card is better than the Radeon Vega 8 in our tests.

In our comparison, 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 slightly higher boost clock speed. This is a frequency that can be reached if the GPU is cooled sufficiently and has enough power.

In addition, the Radeon Vega 8 has a slightly lower TDP at 45 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 Vega 8.
