Radeon RX 480 vs Radeon RX 580 comparison
For gaming, the Radeon RX 580 graphics card is better than the Radeon RX 480 in our tests.
The Radeon RX 480 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. Despite this, the Radeon RX 580 has a slightly higher boost clock speed. This is a frequency that can be reached if the GPU is cooled sufficiently and has enough power.
Next up, in terms of GPU memory, they both have the same amount of memory at 8 GiB. Lots of memory is good when playing at high resolutions or with many monitors.
In addition, the Radeon RX 480 has a slightly lower TDP at 150 W when compared to the Radeon RX 580 at 185 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 RX 580 over the Radeon RX 480.
