In terms of overall gaming performance, the graphical capabilities of the AMD Radeon RX 590 8GB are very slightly better than the AMD Radeon RX 480 8GB.

The RX 590 has a 349 MHz higher core clock speed and the same number of Texture Mapping Units as the RX 480. This results in the RX 590 providing 50.2 GTexel/s better texturing performance. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The RX 590 has a 349 MHz higher core clock speed than the RX 480 and the same number of Render Output Units. This results in the RX 590 providing 11.2 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The RX 590 was released over a year more recently than the RX 480, and so the RX 590 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the RX 480.

Both GPUs exhibit very powerful performance, so it probably isn't worth upgrading from one to the other, as both are capable of running even the most demanding games at the highest settings.

The Radeon RX 590 8GB and the Radeon RX 480 8GB have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The memory bandwidth of the Radeon RX 590 8GB and the Radeon RX 480 8GB are the same, which means the RX 590 and the RX 480 have equal limitations when it comes to graphical data transfer.

Both the Radeon RX 590 8GB and the Radeon RX 480 8GB have 2304 Shader Processing Units. While the two GPUs have the same number of SPUs, the actual performance delivered by the RX 590 is 3560 and by the RX 480 is 2917. Knowing that the shader performance of the RX 590 is superior, it is not necessary to examine the GPUs' respective Texture and Pixel Fill Rates.

The RX 590 transistor size technology is 2 nm (nanometers) smaller than the RX 480. This means that the RX 590 is expected to run very slightly cooler and achieve higher clock frequencies than the RX 480.

The Radeon RX 590 8GB requires 175 Watts to run and the Radeon RX 480 8GB requires 150 Watts. We would recommend a PSU with at least 500 Watts for the RX 590 and a PSU with at least 500 Watts for the RX 480. The RX 590 requires 25 Watts more than the RX 480 to run. The difference is not significant enough for the RX 590 to have a noticeably larger impact on your yearly electricity bills than the RX 480.
