Radeon R9 270 vs Radeon RX 560X comparison

For gaming, the Radeon R9 270 graphics card is better than the Radeon RX 560X in our tests.

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. In addition, the Radeon RX 560X also has a slightly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

Furthermore, the spec sheet for both these GPUs show that 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 RX 560X has a significantly lower TDP at 75 W when compared to the Radeon R9 270 at 150 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 R9 270 over the Radeon RX 560X.
