Radeon R9 390 vs Radeon RX 470 benchmarks

For gaming, the Radeon R9 390 graphics card is better than the Radeon RX 470 in our tests.

Our database shows that the Radeon R9 390 has a slightly higher core clock speed. The core clock speed (or base speed) is the frequency at which the GPU core runs. This metric makes sense when comparing GPUs of a similar architecture or generation. Despite this, the Radeon RX 470 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.

Furthermore, the spec sheet for both these GPUs show that they both have the same amount of memory at 8 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.

In addition, the Radeon RX 470 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 Radeon R9 390 over the Radeon RX 470.
