Radeon R9 280X vs Radeon RX 460 comparison

For gaming, the Radeon R9 280X graphics card is better than the Radeon RX 460 in our tests.

Our database shows that 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.

As stated by the manufacturer, the Radeon RX 460 has slightly more memory with 4 GiB of memory compared to 3 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 280X at 250 W. TDP (Thermal Design Power) measures total heat output from the chip.

In terms of raw gaming performance in our GPU benchmark, the Radeon R9 280X is better than the Radeon RX 460.
