GeForce GTX 1660 vs Radeon R9 390X benchmarks

For gaming, the GeForce GTX 1660 graphics card is better than the Radeon R9 390X in our tests.

In our comparison, the GeForce GTX 1660 has a significantly 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 GTX 1660 also has a significantly 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.

Furthermore, the spec sheet for both these GPUs show that the Radeon R9 390X has slightly more memory with 8 GiB of memory compared to 6 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.

In addition, the GeForce GTX 1660 has a significantly lower TDP at 120 W when compared to the Radeon R9 390X at 275 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 GTX 1660 is better than the Radeon R9 390X.
