GeForce GTX 780 Ti vs Radeon RX 6400 benchmarks

According to the hardwareDB Benchmark, the GeForce GTX 780 Ti GPU is faster than the Radeon RX 6400 in gaming.

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. 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.

Furthermore, the spec sheet for both these GPUs show that the Radeon RX 6400 has slightly more memory with 4 GiB of memory compared to 3 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 GeForce GTX 780 Ti at 250 W. Heat output doesn't match power consumption directly but, it's a good estimate.

According to the results of the hardwareDB benchmark utility, the GeForce GTX 780 Ti is faster than the Radeon RX 6400.
