In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R9 295X2 are significantly better than the Nvidia GeForce GTX 770 Zotac AMP! Edition.

The GTX 770 has a 132 MHz higher core clock speed than the Radeon R9 295X2, but the Radeon R9 295X2 has 224 more Texture Mapping Units than the GTX 770. As a result, the Radeon R9 295X2 exhibits a 211.1 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 132 MHz higher core clock speed than the Radeon R9 295X2, but the Radeon R9 295X2 has 96 more Render Output Units than the GTX 770. As a result, the Radeon R9 295X2 exhibits a 93.5 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 Radeon R9 295X2 was released less than a year after the GTX 770, and so they are likely to have similar driver support for optimizing performance 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 Radeon R9 295X2 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 Radeon R9 295X2 also has superior memory performance overall.

The Radeon R9 295X2 has 409.6 GB/sec greater memory bandwidth than the GTX 770, which means that the memory performance of the Radeon R9 295X2 is massively better than the GTX 770.

The Radeon R9 295X2 has 5632 Shader Processing Units and the GeForce GTX 770 Zotac AMP! Edition has 1536. However, the actual shader performance of the Radeon R9 295X2 is 4873 and the actual shader performance of the GTX 770 is 1846. The Radeon R9 295X2 having 3027 better shader performance and an altogether better performance when taking into account other relevant data means that the Radeon R9 295X2 delivers a massively smoother and more efficient experience when processing graphical data than the GTX 770.

The Radeon R9 295X2 requires 500 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 Radeon R9 295X2 and a PSU with at least 600 Watts for the GTX 770. The Radeon R9 295X2 has been recommended a PSU with 250 Watts more than the GTX 770. The difference is significant enough that the Radeon R9 295X2 may have an adverse affect on your yearly electricity bills in comparison to the GTX 770.

GPU Mini Review

Mini ReviewOverview
Radeon R9 295X2 is a Dual-Graphics Solution based on the First Revision of the Graphics Core Next (GCN) Architecture.

Architecture
The GCN 1.1 revision of the Graphics Core Next Architecture adds new important technologies and is largely oriented for energy efficiency. New technologies such as PowerTune and TrueAudio are the biggest additions as well as DirectX 11.2 support.

GPU
It equips two GPUs Codenamed Hawaii XT which together have 128 Compute Units activated and thus offer 5632 Shader Processing Units, 352 TMUs and 128 ROPs. The Central Unit is clocked at 1018MHz.

Memory
Each GPU accesses a 4GB frame buffer of fast GDDR5 Memory, through a 512-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 1250MHz.

Power Consumption
With a rated board TDP of 500W, it requires at least a 850W PSU with two available 8-pin connectors.

Performance
Radeon R9 295X2 Competes with GeForce GTX Titan Z and proves to be much faster than the latter, especially at 4K.
Radeon R9 295X2 is the fastest Dual Graphics Solution as of June of 2015.

System Suggestions
Radeon R9 295X2 is best suited for resolutions up to and including 3840x2160. We recommend a Very Strong Processor (Intel Core i7 Quad Core/AMD FX Eight Core) 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.
