In terms of overall gaming performance, the graphical capabilities of the GT 430 and the GT 730 are equal.

The GT 430 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 430 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 three years more recently than the GT 430, 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 GT 430 when running the latest games.

The GT 430 has 2048 MB more video memory than the GT 730, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the GT 730 has superior memory performance.

The GT 730 has 11.7 GB/sec greater memory bandwidth than the GT 430, which means that the memory performance of the GT 730 is slightly better than the GT 430.

Both the GeForce GT 430 Zotac Synergy 4GB Edition and the GeForce GT 730 v3 Gigabyte 2GB Edition have 96 Shader Processing Units. The two GPUs are based on different architectures, but deliver an equivalent shader performance. To compare, we must continue to look 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 430 Zotac Synergy 4GB Edition requires 49 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 430 and a PSU with at least 300 Watts for the GT 730. The two GPUs require the same amount of wattage to run. As such, there is no need to worry about which will more significantly affect your yearly electricity bills.
