Gaming Performance Comparison
In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 680 are massively better than the AMD Radeon HD 7790.
The Radeon HD 7790 was released less than a year after the GeForce GTX 680, and so they are likely to have similar driver support for optimizing performance when running the latest games.
The GeForce GTX 680 has 1024 MB more video memory than the Radeon HD 7790, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GeForce GTX 680 also has superior memory performance overall.
The GeForce GTX 680 has 96.3 GB/sec greater memory bandwidth than the Radeon HD 7790, which means that the memory performance of the GeForce GTX 680 is massively better than the Radeon HD 7790.
The Radeon HD 7790 has 896 Shader Processing Units and the GeForce GTX 680 has 1536. However, the actual shader performance of the Radeon HD 7790 is 582.4. The GeForce GTX 680 having 953.6 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GTX 680 delivers a massively smoother and more efficient experience when processing graphical data than the Radeon HD 7790.
The Radeon HD 7790 requires 85 Watts to run and the GeForce GTX 680 requires 195 Watts. We would recommend a PSU with at least 500 Watts for the Radeon HD 7790 and a PSU with at least 550 Watts for the GeForce GTX 680. The GeForce GTX 680 requires 110 Watts more than the Radeon HD 7790 to run. The difference is significant enough that the GeForce GTX 680 may have an adverse affect on your yearly electricity bills in comparison to the Radeon HD 7790.

|Mini Review||Radeon HD 7790 is a fast-middle-class/performance graphics card based on the 28nm, GCN architecture. |
It's based on the Bonaire XT Core and therefore offer 896 Shader Processing Units, 56 TMUs and 16 ROPs on a 128-bit memory interface of fast GDDR5. The central unit runs at 1000MHz and the memory clock will operate at up to 1500MHz. It consumes up to 85 Watt.
This Graphics Card is added one year after the Radeon HD 7000 Series to compete against NVIDIA's GeForce GTX 650 Ti and benchmarks indicate its performance is between 3 and 7% better. However, NVIDIA is also set to release a new graphics card called GeForce GTX 650 Ti Boost Edition which is expected to be up to 10% better than GeForce GTX 650 Ti and so it will outperform this card.
With the release price of 150 USD, AMD's Radeon HD 7770 might become obsolete. This Graphics Card needs to be paired with a strong Dual Core CPU.
|GeForce GTX 680 is a high-end Graphics Card based on the 28nm, Kepler architecture. |
The Kepler architecture allows more SPUs but the Fermi SPUs (used on the 400 & 500 Series) are clocked twice as fast as the Kepler architecture. Therefore, don't let the large amount of Pipelines fool you, as the 1536 Pipelines are equivalent to 768 Pipelines, of the Fermi architecture.
GeForce GTX 680 features a 1006Mhz core-clock that can automatically set itself to 1058Mhz using a technology similar to the one used on Intel GPUs. Another huge surprise is the TDP that went from 244 Watts, to just 195 Watts, as two SPUs of the Kepler architecture consume 10% less power. However, the amount was doubled and so the power save is not as high as it could have been.
GeForce GTX 680 was the fastest single GPU of the world until Radeon HD 7970 GHz Edition was released.
All games will run on the maximum settings smoothly.
