GeForce GTX 950 vs Radeon R9 390 specs and performance

For gaming, the Radeon R9 390 graphics card is better than the GeForce GTX 950 in our tests.

The GeForce GTX 950 has a slightly 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 950 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.

As stated by the manufacturer, the Radeon R9 390 has significantly more memory with 8 GiB of memory compared to 2 GiB. Lots of memory is good when playing at high resolutions or with many monitors.

In addition, the GeForce GTX 950 has a significantly lower TDP at 90 W when compared to the Radeon R9 390 at 275 W. Heat output doesn't match power consumption directly but, it's a good estimate.

In conclusion, all specs and GPU benchmarks considered, will recommend the Radeon R9 390 over the GeForce GTX 950.
