Radeon RX 6750 XT vs Radeon RX 6400 benchmarks

According to the hardwareDB Benchmark, the Radeon RX 6750 XT GPU is faster than the Radeon RX 6400 in gaming.

The Radeon RX 6750 XT has a slightly 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 6750 XT 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.

Furthermore, the spec sheet for both these GPUs show that the Radeon RX 6750 XT has significantly more memory with 12 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 6750 XT 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.

In terms of raw gaming performance in our GPU benchmark, the Radeon RX 6750 XT is better than the Radeon RX 6400.
