GeForce RTX 2080 vs Radeon RX 6400 benchmarks

In our benchmarks, the GeForce RTX 2080 beats the Radeon RX 6400 in gaming performance.

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 maximum frequency the chip can reach if power delivery and thermals allow.

Next up, in terms of GPU memory, the GeForce RTX 2080 has significantly more memory with 8 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 GeForce RTX 2080 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 GeForce RTX 2080 is better than the Radeon RX 6400.
