GeForce GTX 1080 vs Radeon R9 390X comparison

For gaming, the GeForce GTX 1080 graphics card is better than the Radeon R9 390X in our tests.

In our comparison, the GeForce GTX 1080 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 1080 also has a significantly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

Furthermore, the spec sheet for both these GPUs show that they both have the same amount of memory at 8 GiB. Lots of memory is good when playing at high resolutions or with many monitors.

In addition, the GeForce GTX 1080 has a significantly lower TDP at 180 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 1080 is better than the Radeon R9 390X.
