Radeon R9 390X vs Radeon RX 470 comparison

In our benchmarks, the Radeon RX 470 beats the Radeon R9 390X in gaming performance.

Our database shows that the Radeon R9 390X 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 Radeon RX 470 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 470 has a significantly lower TDP at 120 W when compared to the Radeon R9 390X 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 470 over the Radeon R9 390X.
