In terms of overall gaming performance, the graphical capabilities of the AMD Radeon R7 260X are very slightly better than the AMD Radeon HD 7790.

The Radeon R7 260X has a 100 MHz higher core clock speed and the same number of Texture Mapping Units as the Radeon HD 7790. This results in the Radeon R7 260X providing 5.6 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 Radeon R7 260X has a 100 MHz higher core clock speed than the Radeon HD 7790 and the same number of Render Output Units. This results in the Radeon R7 260X providing 1.6 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 Radeon R7 260X was released less than a year after the Radeon HD 7790, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The Radeon R7 260X 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 Radeon R7 260X also has superior memory performance overall.

The Radeon R7 260X has 8 GB/sec greater memory bandwidth than the Radeon HD 7790, which means that the memory performance of the Radeon R7 260X is marginally better than the Radeon HD 7790.

Both the Radeon R7 260X and the Radeon HD 7790 have 896 Shader Processing Units. While the two GPUs have the same number of SPUs, the actual performance delivered by the . Knowing that the shader performance of the Radeon R7 260X is superior, it is not necessary to examine the GPUs' respective Texture and Pixel Fill Rates.

The Radeon R7 260X requires 115 Watts to run and the Radeon HD 7790 requires 85 Watts. We would recommend a PSU with at least 450 Watts for the Radeon R7 260X and a PSU with at least 450 Watts for the Radeon HD 7790. The Radeon R7 260X requires 30 Watts more than the Radeon HD 7790 to run. The difference is not significant enough for the Radeon R7 260X to have a noticeably larger impact on your yearly electricity bills than the Radeon HD 7790.

GPU Mini Review

Mini ReviewRadeon R7 260X is a fast-middle-class Graphics Card based on the Bonaire XTX core of the Graphics Core Next Architecture.
The Bonaire XTX Core has its roots on the Bonaire XT Core used on Radeon HD 7790. It offers 896 Shader Processing Units, 56 TMUs and 16 ROPs, on a 128-bit memory interface.
However and when compared to Radeon HD 7790, Radeon R7 260X has its central unit running at 1100MHz. Furthermore, its operating memory clock is significantly higher and of 1625MHz, leading to extra memory bandwidth.
Benchmarks indicate its performance is quite superior to its predecessors (Radeon HD 7770), but famous Radeon HD 7850 and its GeForce GTX 650 Ti Boost Edition still offer much more performance.
Expect to run most modern demanding games, such as Crysis 3 and Metro Last Light at high-settings, though a 1080p resolution will probably reduce your gaming experience and something more modest might be best suited.
Radeon R7 260X has a launching price of just $139 which makes it a very uncompetitive card, since Radeon HD 7850 is available for $140 these days.
Overview
Radeon HD 7790 is a Fast-Middle-Class Graphics Card based on the First Revision of the Graphics Core Next (GCN) Architecture.

Architecture
The GCN Architecture succeeds the 40nm Terascale Architecture. In addition to being produced with a 28nm Technology, the GCN Architecture adds other Technologies that allow for energy efficiency. For example, ZeroCore Power, a long idle power saving technology, allows the Graphics Cards to shut down by itself when the Monitor is turned off.
GCN also adds Improved Anisotropic Filtering, DirectX 11 Tessellation and the Partially Resident Textures (PRT) Technology, which enables future games to utilize ultra-high resolution textures with the same performance as today's small and often repetitive textures.

GPU
It equips a GPU Codenamed Bonaire XT which has 14 Compute Units activated and thus offers 896 Shader Processing Units, 56 TMUs and 16 ROPs. The Central Unit is clocked at 1000MHz.

Memory
The GPU accesses a 1GB frame buffer of fast GDDR5, through a 256-bit memory interface. The size of the frame buffer is adequate. The Memory Clock Operates at 1500MHz.

Power Consumption
With a rated board TDP of 85W, it requires at least a 450W PSU with one available 6-pin connectors.

Performance
Radeon HD 7790 competes with GeForce GTX 650 Ti and its performance is slightly above it.

System Suggestions
Radeon HD 7790 is best suited for resolutions up to and including 1600x900. We recommend a Decent Processor (Intel Core i3 Quad Core/AMD FX Quad Core) and 8GB of RAM for Optimal Performance.
