In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7670 v2 are noticeably better than the Nvidia GeForce GT 730 v3 Gigabyte 2GB Edition.

The HD 7670 has a 100 MHz higher core clock speed and 8 more Texture Mapping Units than the GT 730. This results in the HD 7670 providing 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 HD 7670 has a 100 MHz higher core clock speed and 4 more Render Output Units than the GT 730. This results in the HD 7670 providing 3.6 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 GT 730 was released over a year more recently than the HD 7670, and so the GT 730 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the HD 7670.

The Radeon HD 7670 v2 and the GeForce GT 730 v3 Gigabyte 2GB Edition have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The GT 730 has 3.2 GB/sec greater memory bandwidth than the HD 7670, which means that the memory performance of the GT 730 is marginally better than the HD 7670.

The Radeon HD 7670 v2 has 480 Shader Processing Units and the GeForce GT 730 v3 Gigabyte 2GB Edition has 96. However, the actual shader performance of the HD 7670 is 192 and the actual shader performance of the GT 730 is 134. The HD 7670 having 58 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 7670 delivers a marginally smoother and more efficient experience when processing graphical data than the GT 730.

The Radeon HD 7670 v2 requires 66 Watts to run and the GeForce GT 730 v3 Gigabyte 2GB Edition requires 49 Watts. We would recommend a PSU with at least 400 Watts for the HD 7670 and a PSU with at least 300 Watts for the GT 730. The HD 7670 requires 17 Watts more than the GT 730 to run. The difference is not significant enough for the HD 7670 to have a noticeably larger impact on your yearly electricity bills than the GT 730.
