In terms of overall gaming performance, the graphical capabilities of the AMD Radeon RX 590 ASRock Phantom Gaming X OC 8GB are significantly better than the Nvidia GeForce GTX 770 Zotac AMP! Edition.

The RX 590 has a 319 MHz higher core clock speed and 16 more Texture Mapping Units than the GTX 770. This results in the RX 590 providing 64.3 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 319 MHz higher core clock speed than the GTX 770 and the same number of Render Output Units. This results in the RX 590 providing 10.2 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 three years more recently than the GTX 770, and so the RX 590 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GTX 770 when running the latest games.

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 RX 590 has 6144 MB more video memory than the GTX 770, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the RX 590 also has superior memory performance overall.

The RX 590 has 26.6 GB/sec greater memory bandwidth than the GTX 770, which means that the memory performance of the RX 590 is slightly better than the GTX 770.

The Radeon RX 590 ASRock Phantom Gaming X OC 8GB has 2304 Shader Processing Units and the GeForce GTX 770 Zotac AMP! Edition has 1536. However, the actual shader performance of the RX 590 is 3666 and the actual shader performance of the GTX 770 is 1846. The RX 590 having 1820 better shader performance and an altogether better performance when taking into account other relevant data means that the RX 590 delivers a massively smoother and more efficient experience when processing graphical data than the GTX 770.

The RX 590 transistor size technology is 16 nm (nanometers) smaller than the GTX 770. This means that the RX 590 is expected to run slightly cooler and achieve higher clock frequencies than the GTX 770.

The Radeon RX 590 ASRock Phantom Gaming X OC 8GB requires 175 Watts to run but there is no entry for the GeForce GTX 770 Zotac AMP! Edition. We would recommend a PSU with at least 500 Watts for the RX 590 and a PSU with at least 600 Watts for the GTX 770. The GTX 770 has been recommended a PSU with 100 Watts more than the RX 590. The difference is significant enough that the GTX 770 may have an adverse affect on your yearly electricity bills in comparison to the RX 590.
