In terms of overall gaming performance, the graphical capabilities of the AMD Radeon RX 570 PowerColor Red Dragon 4GB are noticeably better than the Nvidia GeForce GTX 770 Zotac AMP! Edition.

The RX 570 has a 18 MHz higher core clock speed and the same number of Texture Mapping Units as the GTX 770. This results in the RX 570 providing 2.3 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 570 has a 18 MHz higher core clock speed than the GTX 770 and the same number of Render Output Units. This results in the RX 570 providing 0.6 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 570 was released over three years more recently than the GTX 770, and so the RX 570 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 570 has 2048 MB more video memory than the GTX 770, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the GTX 770 has superior memory performance.

The GTX 770 has 6.4 GB/sec greater memory bandwidth than the RX 570, which means that the memory performance of the GTX 770 is marginally better than the RX 570.

The Radeon RX 570 PowerColor Red Dragon 4GB has 2048 Shader Processing Units and the GeForce GTX 770 Zotac AMP! Edition has 1536. However, the actual shader performance of the RX 570 is 2560 and the actual shader performance of the GTX 770 is 1846. The RX 570 having 714 better shader performance and an altogether better performance when taking into account other relevant data means that the RX 570 delivers a noticeably smoother and more efficient experience when processing graphical data than the GTX 770.

The RX 570 transistor size technology is 14 nm (nanometers) smaller than the GTX 770. This means that the RX 570 is expected to run slightly cooler and achieve higher clock frequencies than the GTX 770.

The Radeon RX 570 PowerColor Red Dragon 4GB requires 120 Watts to run but there is no entry for the GeForce GTX 770 Zotac AMP! Edition. We would recommend a PSU with at least 450 Watts for the RX 570 and a PSU with at least 600 Watts for the GTX 770. The GTX 770 has been recommended a PSU with 150 Watts more than the RX 570. The difference is significant enough that the GTX 770 may have an adverse affect on your yearly electricity bills in comparison to the RX 570.
