Radeon RX 6800 vs Radeon RX 6400 specs and performance

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

Our database shows that the Radeon RX 6400 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. 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.

Next up, in terms of GPU memory, the Radeon RX 6800 has significantly more memory with 16 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 6800 at 250 W. This is not a measure of performance, but rather the amount of heat generated by the chip when running at its highest speed.

According to the results of the hardwareDB benchmark utility, the Radeon RX 6800 is faster than the Radeon RX 6400.
