In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 770 Leadtek Hurricane III Edition are massively better than the AMD Radeon HD 7790 Sapphire OC Edition.

The GTX 770 has a 9 MHz higher core clock speed and 72 more Texture Mapping Units than the HD 7790. This results in the GTX 770 providing 76.8 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 9 MHz higher core clock speed and 16 more Render Output Units than the HD 7790. This results in the GTX 770 providing 17.1 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 less than a year after the HD 7790, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The GTX 770 has 2048 MB more video memory than the HD 7790, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GTX 770 also has superior memory performance overall.

The GTX 770 has 121.9 GB/sec greater memory bandwidth than the HD 7790, which means that the memory performance of the GTX 770 is massively better than the HD 7790.

The GeForce GTX 770 Leadtek Hurricane III Edition has 1536 Shader Processing Units and the Radeon HD 7790 Sapphire OC Edition has 896. However, the actual shader performance of the GTX 770 is 1706 and the actual shader performance of the HD 7790 is 941. The GTX 770 having 765 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 HD 7790.

The GeForce GTX 770 Leadtek Hurricane III Edition requires 230 Watts to run but there is no entry for the Radeon HD 7790 Sapphire OC Edition. We would recommend a PSU with at least 600 Watts for the GTX 770 and a PSU with at least 500 Watts for the HD 7790. The GTX 770 has been recommended a PSU with 100 Watts more than the HD 7790. The difference is significant enough that the GTX 770 may have an adverse affect on your yearly electricity bills in comparison to the HD 7790.

GPU Mini Review

Mini ReviewGeForce GTX 770 Leadtek Hurricane III Edition is a special edition of the high-end GeForce GTX 770.
This edition comes with a custom triple 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 1059MHz while its boost clock is now of 1111MHz. The memory clock was left untouched.
Benchmarks indicate a 3% performance boost when compared to the reference card.
Note: This card has 2GB and 4GB versions. Both offer the same performance.
Radeon HD 7790 Sapphire OC Edition is a special edition of the performance Radeon HD 7790.
This edition comes with a cooling solution that uses a dual heatpipe system. It also comes overclocked out of the box in the core-clock to 1050MHz and on the memory clock to 1600MHz, though the latter might prove useless, as this card might not benefit from extra bandwidth.
Benchmarks indicate a 4% performance boost when compared to the reference card.
