GeForce RTX 3090 vs Radeon RX 6400 specs and performance

For gaming, the GeForce RTX 3090 graphics card is better than the Radeon RX 6400 in our tests.

In our comparison, the Radeon RX 6400 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 6400 also 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.

As stated by the manufacturer, the GeForce RTX 3090 has significantly more memory with 24 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 GeForce RTX 3090 at 350 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 RTX 3090 is faster than the Radeon RX 6400.
