In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R9 390 XFX Double Dissipation 8GB Edition are noticeably better than the Nvidia GeForce GTX 770 Zotac AMP! Edition.

The GTX 770 has a 150 MHz higher core clock speed than the R9 390, but the R9 390 has 32 more Texture Mapping Units than the GTX 770. As a result, the R9 390 exhibits a 12.8 GTexel/s better Texture Fill Rate than the GTX 770. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GTX 770 has a 150 MHz higher core clock speed than the R9 390, but the R9 390 has 32 more Render Output Units than the GTX 770. As a result, the R9 390 exhibits a 27.2 GPixel/s better Pixel Fill Rate than the GTX 770. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The R9 390 was released over a year more recently than the GTX 770, and so the R9 390 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GTX 770.

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 R9 390 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 R9 390 also has superior memory performance overall.

The R9 390 has 153.6 GB/sec greater memory bandwidth than the GTX 770, which means that the memory performance of the R9 390 is massively better than the GTX 770.

The Radeon R9 390 XFX Double Dissipation 8GB Edition has 2560 Shader Processing Units and the GeForce GTX 770 Zotac AMP! Edition has 1536. However, the actual shader performance of the R9 390 is 2176 and the actual shader performance of the GTX 770 is 1846. The R9 390 having 330 better shader performance and an altogether better performance when taking into account other relevant data means that the R9 390 delivers a massively smoother and more efficient experience when processing graphical data than the GTX 770.

The Radeon R9 390 XFX Double Dissipation 8GB Edition requires 275 Watts to run but there is no entry for the GeForce GTX 770 Zotac AMP! Edition. We would recommend a PSU with at least 600 Watts for the R9 390 and a PSU with at least 600 Watts for the GTX 770. The two GPUs have been recommended a PSU with the same amount of wattage. As such, there is no need to worry about which will more significantly affect your yearly electricity bills.

Performance
Benchmarks Indicate no Performance Boost over the Reference Radeon R9 390.
GeForce GTX 770 Zotac AMP! Edition is a special edition of GeForce GTX 770.
This edition comes with a custom dual fan cooling solution which by itself should allow a slight performance boost, as GeForce GTX 770 benefits from the GPU Boost 2.0 technology.
Also, it has been overclocked out of the box from 1046MHz to 1150MHz while its boost clock is now of 1202MHz. The memory clock was increased to 1800MHz.
Benchmarks indicate a 8% performance boost when compared to the reference card and so this edition performs slightly better than GeForce GTX 590.
