Radeon R7 450 vs Radeon RX 560X specs and performance

For gaming, the Radeon R7 450 graphics card is better than the Radeon RX 560X in our tests.

Our database shows that the Radeon RX 560X 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.

As stated by the manufacturer, the Radeon RX 560X has significantly more memory with 4 GiB of memory compared to 2 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.

In addition, the Radeon R7 450 has a slightly lower TDP at 65 W when compared to the Radeon RX 560X at 75 W. Heat output doesn't match power consumption directly but, it's a good estimate.

In conclusion, all specs and GPU benchmarks considered, will recommend the Radeon R7 450 over the Radeon RX 560X.
