Radeon R9 390 vs Radeon RX 480 comparison

In our benchmarks, the Radeon RX 480 beats the Radeon R9 390 in gaming performance.

Our database shows that the Radeon RX 480 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 Radeon RX 480 also has a slightly 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 they both have the same amount of memory at 8 GiB. Lots of memory is good when playing at high resolutions or with many monitors.

In addition, the Radeon RX 480 has a significantly lower TDP at 150 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 Radeon RX 480 over the Radeon R9 390.
