Radeon R9 390X vs Radeon RX 460 specs and performance

In our benchmarks, the Radeon RX 460 beats the Radeon R9 390X in gaming performance.

In our comparison, the Radeon RX 460 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. In addition, the Radeon RX 460 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.

Next up, in terms of GPU memory, the Radeon R9 390X has significantly more memory with 8 GiB of memory compared to 4 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.

In addition, the Radeon RX 460 has a significantly lower TDP at 75 W when compared to the Radeon R9 390X at 275 W. TDP (Thermal Design Power) measures total heat output from the chip.

In terms of raw gaming performance in our GPU benchmark, the Radeon RX 460 is better than the Radeon R9 390X.
