In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 770 Zotac AMP! Edition are significantly better than the AMD Radeon HD 7850.

The GTX 770 has a 290 MHz higher core clock speed and 64 more Texture Mapping Units than the Radeon HD 7850. This results in the GTX 770 providing 92.2 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 GTX 770 has a 290 MHz higher core clock speed than the Radeon HD 7850 and the same number of Render Output Units. This results in the GTX 770 providing 9.3 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 GTX 770 was released over a year more recently than the Radeon HD 7850, and so the GTX 770 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the Radeon HD 7850.

The GeForce GTX 770 Zotac AMP! Edition and the Radeon HD 7850 have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The GTX 770 has 76.8 GB/sec greater memory bandwidth than the Radeon HD 7850, which means that the memory performance of the GTX 770 is much better than the Radeon HD 7850.

The GeForce GTX 770 Zotac AMP! Edition has 1536 Shader Processing Units and the Radeon HD 7850 has 1024. However, the actual shader performance of the GTX 770 is 1846 and the actual shader performance of the Radeon HD 7850 is 749. The GTX 770 having 1097 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 770 delivers a massively smoother and more efficient experience when processing graphical data than the Radeon HD 7850.

The Radeon HD 7850 requires 130 Watts to run but there is no entry for the GTX 770. We would recommend a PSU with at least 600 Watts for the GTX 770 and a PSU with at least 500 Watts for the Radeon HD 7850. The GTX 770 has been recommended a PSU with 100 Watts more than the Radeon HD 7850. The difference is significant enough that the GTX 770 may have an adverse affect on your yearly electricity bills in comparison to the Radeon HD 7850.

GPU Mini Review

Mini ReviewGeForce 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.
Radeon HD 7850 is a high-end GPU based on 28nm GCN architecture.
It's based on the Pitcairn Core (Pro variant) and therefore offers 1024 Shader Processing Units, 64 TMUs and 32 ROPs on a 256-bit interface of fast GDDR5. The central unit is clocked at 860MHz while the memory clock operates at 1200MHZ.
It offers great performance, almost on level with previously acclaimed Radeon HD 6970. Therefore, most demanding games are playable at the highest settings with fluent frame rates, using a 1080p resolution.
Radeon HD 7850 was elected the best GPU of 2012 by the GD community, thanks to its accessible price and outstanding performance.
