GeForce GTX 950 vs Radeon RX 550 benchmarks

For gaming, the GeForce GTX 950 graphics card is better than the Radeon RX 550 in our tests.

Our database shows that the Radeon RX 550 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. Despite this, the GeForce GTX 950 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 RX 550 has significantly more memory with 4 GiB of memory compared to 2 GiB. Lots of memory is good when playing at high resolutions or with many monitors.

In addition, the Radeon RX 550 has a significantly lower TDP at 50 W when compared to the GeForce GTX 950 at 90 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 950 over the Radeon RX 550.
