In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 770 are massively better than the AMD Radeon HD 7790.

The GeForce GTX 770 has a 46 MHz higher core clock speed and 72 more Texture Mapping Units than the Radeon HD 7790. This results in the GeForce GTX 770 providing 77.9 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 GeForce GTX 770 has a 46 MHz higher core clock speed and 16 more Render Output Units than the Radeon HD 7790. This results in the GeForce GTX 770 providing 17.5 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 GeForce GTX 770 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 GeForce GTX 770 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 770 also has superior memory performance overall.

The GeForce GTX 770 has 128.3 GB/sec greater memory bandwidth than the Radeon HD 7790, which means that the memory performance of the GeForce GTX 770 is massively better than the Radeon HD 7790.

The Radeon HD 7790 has 896 Shader Processing Units and the GeForce GTX 770 has 1536. However, the actual shader performance of the GeForce GTX 770 is 1667. The GeForce GTX 770 having 771 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GTX 770 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 770 requires 230 Watts. We would recommend a PSU with at least 450 Watts for the Radeon HD 7790 and a PSU with at least 550 Watts for the GeForce GTX 770. The GeForce GTX 770 requires 145 Watts more than the Radeon HD 7790 to run. The difference is significant enough that the GeForce GTX 770 may have an adverse affect on your yearly electricity bills in comparison to the Radeon HD 7790.

GPU Mini Review

Mini ReviewOverview
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.
