In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R9 390 Crossfire are significantly 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 192 more Texture Mapping Units than the GTX 770. As a result, the R9 390 exhibits a 172.8 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 96 more Render Output Units than the GTX 770. As a result, the R9 390 exhibits a 91.2 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 14336 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 537.6 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 Crossfire has 5120 Shader Processing Units and the GeForce GTX 770 Zotac AMP! Edition has 1536. However, the actual shader performance of the R9 390 is 4352 and the actual shader performance of the GTX 770 is 1846. The R9 390 having 2506 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 Crossfire requires 550 Watts to run but there is no entry for the GeForce GTX 770 Zotac AMP! Edition. We would recommend a PSU with at least 850 Watts for the R9 390 and a PSU with at least 600 Watts for the GTX 770. The R9 390 has been recommended a PSU with 250 Watts more than the GTX 770. The difference is significant enough that the R9 390 may have an adverse affect on your yearly electricity bills in comparison to the GTX 770.

GPU Mini Review

Mini ReviewOverview
Radeon R9 390 Crossfire is a solution of two Radeon R9 390 put together using AMD's Crossfire Technology.

Architecture
Radeon R9 390 Features a GPU Codenamed Grenada PRO which is a Second Gen GCN GPU and is identical to the Hawaii PRO GPU used on the older Radeon R9 290.

Grenada PRO has 40 Compute Units Unlocked and offers 2560 Shader Processing Units, 160 TMUs and 64 ROPs.

GPU
The Central Unit runs at 1000MHz.

Memory: Speed
Each GPU is equipped with fast GDDR5 and Accesses the Frame Buffer through a 512-bit Memory Interface. The Memory Clock Operates at 1500MHz.

Memory: Frame Buffer
The GPU can fill up a Memory Pool of up to 8GB. Under most circumstances, this only proves useful in certain 3D Games whose Settings Require Large Amounts of Memory.
However, because the GPU itself is too weak to work under other circumstances in which 8GB of Memory are needed - such as 4K Gaming, a Large Frame Buffer is mostly a Gimmick.

Power Consumption
Power Consumption is around 550W.

Performance
Performance is Sufficient for Detailed Gaming at 4K.

System Suggestions
We recommend a High-End Processor and 16GB of RAM for Optimal Performance.
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.
