Radeon RX 6800 XT vs Radeon RX 6400 benchmarks

According to the hardwareDB Benchmark, the Radeon RX 6800 XT GPU is faster than the Radeon RX 6400 in gaming.

The Radeon RX 6800 XT has a slightly 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. Despite this, the Radeon RX 6400 has a slightly higher boost clock speed. The boost clock speed is the frequency that the GPU core can reach if the temperature is low enough. The allows for higher performance in certain scenarios.

Next up, in terms of GPU memory, the Radeon RX 6800 XT has significantly more memory with 16 GiB of memory compared to 4 GiB. Lots of memory is good when playing at high resolutions or with many monitors.

In addition, the Radeon RX 6400 has a significantly lower TDP at 53 W when compared to the Radeon RX 6800 XT at 300 W. Heat output doesn't match power consumption directly but, it's a good estimate.

In conclusion, all specs and GPU benchmarks considered, will recommend the Radeon RX 6800 XT over the Radeon RX 6400.
