In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 980 Palit JetStream 4GB Edition are very slightly better than the AMD Radeon RX 480 4GB.

The GTX 980 has a 6 MHz higher core clock speed than the RX 480, but the RX 480 has 16 more Texture Mapping Units than the GTX 980. As a result, the RX 480 exhibits a 17.2 GTexel/s better Texture Fill Rate than the GTX 980. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GTX 980 has a 6 MHz higher core clock speed and 32 more Render Output Units than the RX 480. This results in the GTX 980 providing 36.3 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 480 was released over a year more recently than the GTX 980, and so the RX 480 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GTX 980.

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 480 4GB and the GeForce GTX 980 Palit JetStream 4GB Edition have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The GTX 980 has 0.4 GB/sec greater memory bandwidth than the RX 480, which means that the memory performance of the GTX 980 is marginally better than the RX 480.

The Radeon RX 480 4GB has 2304 Shader Processing Units and the GeForce GTX 980 Palit JetStream 4GB Edition has 2048. However, the actual shader performance of the RX 480 is 2917 and the actual shader performance of the GTX 980 is 3362. The GTX 980 having 445 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 980 delivers a marginally smoother and more efficient experience when processing graphical data than the RX 480.

The RX 480 transistor size technology is 14 nm (nanometers) smaller than the GTX 980. This means that the RX 480 is expected to run slightly cooler and achieve higher clock frequencies than the GTX 980.

The Radeon RX 480 4GB requires 120 Watts to run and the GeForce GTX 980 Palit JetStream 4GB Edition requires 180 Watts. We would recommend a PSU with at least 450 Watts for the RX 480 and a PSU with at least 500 Watts for the GTX 980. The GTX 980 requires 60 Watts more than the RX 480 to run. The difference is significant enough that the GTX 980 may have an adverse affect on your yearly electricity bills in comparison to the RX 480.
