Radeon R7 450 vs Radeon RX 480 benchmarks

According to the hardwareDB Benchmark, the Radeon RX 480 GPU is faster than the Radeon R7 450 in gaming.

The Radeon RX 480 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.

Furthermore, the spec sheet for both these GPUs show that the Radeon RX 480 has significantly more memory with 8 GiB of memory compared to 2 GiB. If you're planning at playing games at high resolutions with high-quality textures, you will need a lot of memory.

In addition, the Radeon R7 450 has a significantly lower TDP at 65 W when compared to the Radeon RX 480 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 RX 480 over the Radeon R7 450.
