In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 440 Asus 1GB Edition are noticeably better than the Nvidia GeForce GT 730 v3 Gigabyte 2GB Edition.

The GT 440 has a 122 MHz higher core clock speed and the same number of Texture Mapping Units as the GT 730. This results in the GT 440 providing 2 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 440 has a 122 MHz higher core clock speed than the GT 730 and the same number of Render Output Units. This results in the GT 440 providing 0.5 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 440, 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 440 when running the latest games.

The GT 730 has 1024 MB more video memory than the GT 440, so is likely to be much better at displaying game textures at higher resolutions. However, the overall memory performance is about the same.

The GT 440 has 22.4 GB/sec greater memory bandwidth than the GT 730, which means that the memory performance of the GT 440 is slightly better than the GT 730.

Both the GeForce GT 440 Asus 1GB 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, the GT 440 has 2 GTexel/s better Texture Fill Rate, 0.5 GPixel/s better Pixel Fill Rate, and 22.4 GB/sec greater memory bandwidth, so should have a slightly faster performance than the GT 730.

The GeForce GT 440 Asus 1GB 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 440 and a PSU with at least 300 Watts for the GT 730. The GT 440 requires 16 Watts more than the GT 730 to run. The difference is not significant enough for the GT 440 to have a noticeably larger impact on your yearly electricity bills than the GT 730.
