GeForce GTX 1660 SUPER vs Radeon RX 6400 benchmarks

For gaming, the GeForce GTX 1660 SUPER graphics card is better than the Radeon RX 6400 in our tests.

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.

As stated by the manufacturer, the GeForce GTX 1660 SUPER has significantly more memory with 6 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 GTX 1660 SUPER at 125 W. TDP (Thermal Design Power) measures total heat output from the chip.

According to the results of the hardwareDB benchmark utility, the GeForce GTX 1660 SUPER is faster than the Radeon RX 6400.
