In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 4670 AGP are noticeably better than the Nvidia GeForce GT 730 v3 Gigabyte 2GB Edition.

The HD 4670 has a 50 MHz higher core clock speed and 16 more Texture Mapping Units than the GT 730. This results in the HD 4670 providing 12.8 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 4670 has a 50 MHz higher core clock speed and 4 more Render Output Units than the GT 730. This results in the HD 4670 providing 3.2 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 three years more recently than the HD 4670, and so the GT 730 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the HD 4670 when running the latest games.

The GT 730 has 1024 MB more video memory than the HD 4670, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GT 730 also has superior memory performance overall.

The GT 730 has 3.2 GB/sec greater memory bandwidth than the HD 4670, which means that the memory performance of the GT 730 is marginally better than the HD 4670.

The GeForce GT 730 v3 Gigabyte 2GB Edition has 96 Shader Processing Units and the Radeon HD 4670 AGP has 320. However, the actual shader performance of the GT 730 is 134 and the actual shader performance of the HD 4670 is 168. The HD 4670 having 34 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 4670 delivers a marginally smoother and more efficient experience when processing graphical data than the GT 730.

The GT 730 transistor size technology is 15 nm (nanometers) smaller than the HD 4670. This means that the GT 730 is expected to run slightly cooler and achieve higher clock frequencies than the HD 4670.

The GeForce GT 730 v3 Gigabyte 2GB Edition requires 49 Watts to run and the Radeon HD 4670 AGP requires 59 Watts. We would recommend a PSU with at least 300 Watts for the GT 730 and a PSU with at least 400 Watts for the HD 4670. The HD 4670 requires 10 Watts more than the GT 730 to run. The difference is not significant enough for the HD 4670 to have a noticeably larger impact on your yearly electricity bills than the GT 730.
