AMD Radeon RX 6400 vs NVIDIA GeForce RTX 5090

Radeon RX 6400 vs GeForce RTX 5090 comparison

For gaming, the GeForce RTX 5090 graphics card is better than the Radeon RX 6400 in our tests.

In our comparison, the GeForce RTX 5090 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 GeForce RTX 5090 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 GeForce RTX 5090 has significantly more memory with 32 GiB of memory compared to 4 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.

In addition, the Radeon RX 6400 has a significantly lower TDP at 53 W when compared to the GeForce RTX 5090 at 575 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 GeForce RTX 5090 is better than the Radeon RX 6400.
