In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 430 MSI OC 2GB Edition are marginally better than the Nvidia GeForce GT 730 v3 Gigabyte 2GB Edition.

The GT 430 has a 30 MHz higher core clock speed and the same number of Texture Mapping Units as the GT 730. This results in the GT 430 providing 0.5 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 GT 430 has a 30 MHz higher core clock speed than the GT 730 and the same number of Render Output Units. This results in the GT 430 providing 0.1 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 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 730 has 1024 MB more video memory than the GT 430, 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 7.5 GB/sec greater memory bandwidth than the GT 430, which means that the memory performance of the GT 730 is marginally better than the GT 430.

Both the GeForce GT 430 MSI OC 2GB Edition and the GeForce GT 730 v3 Gigabyte 2GB Edition have 96 Shader Processing Units. While the two GPUs have the same number of SPUs, the actual performance delivered by the GT 430 is 140 and by the GT 730 is 134. Knowing that the shader performance of the GT 430 is superior, it is not necessary to examine the GPUs' respective Texture and Pixel Fill Rates.

The GeForce GT 430 MSI OC 2GB 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.
