Radeon R7 450 vs Radeon RX 460 benchmarks

In our benchmarks, the Radeon RX 460 beats the Radeon R7 450 in gaming performance.

In our comparison, the Radeon RX 460 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.

Furthermore, the spec sheet for both these GPUs show that the Radeon RX 460 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 460 at 75 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 RX 460 over the Radeon R7 450.
