Radeon RX 6400 vs GeForce RTX 4070 Laptop benchmarks

In our benchmarks, the GeForce RTX 4070 Laptop 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. This is a frequency that can be reached if the GPU is cooled sufficiently and has enough power.

In addition, the Radeon RX 6400 has a significantly lower TDP at 53 W when compared to the GeForce RTX 4070 Laptop at 115 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 4070 Laptop is better than the Radeon RX 6400.
