GeForce GTX 1660 Ti Max-Q vs Radeon R9 390 benchmarks

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

The GeForce GTX 1660 Ti Max-Q 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 GeForce GTX 1660 Ti Max-Q also has a slightly 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 390 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 Max-Q has a significantly lower TDP at 60 W when compared to the Radeon R9 390 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 Max-Q over the Radeon R9 390.
