In terms of overall gaming performance, the graphical capabilities of the GT 630 and the GT 730 are equal.

The GT 630 and the GT 730 have both the same core clock speed and the same Texture Fill Rate. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GT 630 and the GT 730 have both the same core clock speed and the same Pixel Fill Rate. 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 GT 630, 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 GT 630.

The GeForce GT 630 Zotac Synergy 2GB Edition 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 7.5 GB/sec greater memory bandwidth than the GT 630, which means that the memory performance of the GT 730 is marginally better than the GT 630.

Both the GeForce GT 630 Zotac Synergy 2GB Edition and the GeForce GT 730 v3 Gigabyte 2GB Edition have 96 Shader Processing Units. Having the same number of SPUs and using the same architecture means that the performance they offer can be compared by looking at the memory bandwidth, Texture and Pixel Rates. In this case, although the GPUs are very similar in performance, the GT 730 takes the edge.

The GeForce GT 630 Zotac Synergy 2GB Edition requires 65 Watts to run and the GeForce GT 730 v3 Gigabyte 2GB Edition requires 49 Watts. We would recommend a PSU with at least 300 Watts for the GT 630 and a PSU with at least 300 Watts for the GT 730. The GT 630 requires 16 Watts more than the GT 730 to run. The difference is not significant enough for the GT 630 to have a noticeably larger impact on your yearly electricity bills than the GT 730.
