GeForce GTX 1660 Ti vs Radeon R9 390 comparison

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

The GeForce GTX 1660 Ti 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 Ti also has a significantly higher boost clock speed. This is a frequency that can be reached if the GPU is cooled sufficiently and has enough power.

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. If you're planning at playing games at high resolutions with high-quality textures, you will need a lot of memory.

In addition, the GeForce GTX 1660 Ti has a significantly lower TDP at 120 W when compared to the Radeon R9 390 at 275 W. TDP (Thermal Design Power) measures total heat output from the chip.

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