GeForce GTX 1660 Ti vs Radeon R9 390X benchmarks

In our benchmarks, the GeForce GTX 1660 Ti beats the Radeon R9 390X in gaming performance.

The GeForce GTX 1660 Ti has a much 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 GeForce GTX 1660 Ti 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. Lots of memory is good when playing at high resolutions or with many monitors.

In addition, the GeForce GTX 1660 Ti 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 conclusion, all specs and GPU benchmarks considered, will recommend the GeForce GTX 1660 Ti over the Radeon R9 390X.
