Gaming Performance Comparison
In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 770 are noticeably better than the AMD Radeon HD 7970 GHz Edition.
The GeForce GTX 770 was released less than a year after the HD 7970, 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 HD 7970 GHz Edition and the GeForce GTX 770 have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.
The HD 7970 has 63.7 GB/sec greater memory bandwidth than the GeForce GTX 770, which means that the memory performance of the HD 7970 is much better than the GeForce GTX 770.
The Radeon HD 7970 GHz Edition has 2048 Shader Processing Units and the GeForce GTX 770 has 1536. However, the actual shader performance of the HD 7970 is 1331.2. The GeForce GTX 770 having 204.8 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GTX 770 delivers a noticeably smoother and more efficient experience when processing graphical data than the HD 7970.
The Radeon HD 7970 GHz Edition requires 300 Watts to run and the GeForce GTX 770 requires 230 Watts. We would recommend a PSU with at least 500 Watts for the HD 7970 and a PSU with at least 550 Watts for the GeForce GTX 770. The HD 7970 requires 70 Watts more than the GeForce GTX 770 to run. The difference is significant enough that the HD 7970 may have an adverse affect on your yearly electricity bills in comparison to the GeForce GTX 770.

|Mini Review||Radeon HD 7970 GHz Edition, codenamed Tahiti XT2, is the successor to Radeon HD 7970. |
In this edition, the core configuration remains the same. The core-clock was increased from 925MHz to 1000MHz (1050MHz in Turbo) and the memory clock from 1375MHz to 1500MHz.
Benchmarks indicate the performance is around 10% superior than Radeon HD 7970 and so it was 2012 most powerful single Graphics Card.
As of 2013, it's still one of the fastest but GeForce GTX 780 & GeForce GTX TITAN offer superior performance.
|GeForce GTX 770 is a high-end graphics card based on the 28nm, Kepler architecture. |
It's based on the Kepler GK104 Core and therefore offer 1536 Shader Processing Units, 128 TMUs and 32 ROPs on a 256-bit memory interface of fast GDDR5. While the central unit runs at 1046MHz and goes up to 1085MHz in Turbo Mode, the memory clock operates at 1753MHz. It consumes up to 230W.
It's, therefore, a tweaked GeForce GTX 680 that performs up to 5% better. Therefore, it's suited for a 1080p resolution and to play the most demanding games at the highest settings.
