In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 730 v3 Gigabyte 2GB Edition are significantly better than the AMD Radeon HD 8470 (OEM).

The HD 8470 has a 50 MHz higher core clock speed than the GT 730, but the GT 730 has 8 more Texture Mapping Units than the HD 8470. As a result, the GT 730 exhibits a 5.2 GTexel/s better Texture Fill Rate than the HD 8470. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The HD 8470 has a 50 MHz higher core clock speed than the GT 730 and the same number of Render Output Units. This results in the HD 8470 providing 0.2 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 a year more recently than the HD 8470, 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 8470.

The GT 730 has 1536 MB more video memory than the HD 8470, 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 memory bandwidth of the GeForce GT 730 v3 Gigabyte 2GB Edition and the Radeon HD 8470 (OEM) are the same, which means the GT 730 and the HD 8470 have equal limitations when it comes to graphical data transfer.

The GeForce GT 730 v3 Gigabyte 2GB Edition has 96 Shader Processing Units and the Radeon HD 8470 (OEM) has 160. However, the actual shader performance of the GT 730 is 134 and the actual shader performance of the HD 8470 is 60. The GT 730 having 74 better shader performance and an altogether better performance when taking into account other relevant data means that the GT 730 delivers a marginally smoother and more efficient experience when processing graphical data than the HD 8470.

The GeForce GT 730 v3 Gigabyte 2GB Edition requires 49 Watts to run and the Radeon HD 8470 (OEM) requires 18 Watts. We would recommend a PSU with at least 300 Watts for the GT 730 and a PSU with at least 300 Watts for the HD 8470. The GT 730 requires 31 Watts more than the HD 8470 to run. The difference is significant enough that the GT 730 may have a slight adverse affect on your yearly electricity bills in comparison to the HD 8470.
