In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 140 are very slightly better than the Nvidia GeForce GT 730 v3 Gigabyte 2GB Edition.

The GT 730 has a 50 MHz higher core clock speed than the GeForce GT 140, but the GeForce GT 140 has 16 more Texture Mapping Units than the GT 730. As a result, the GeForce GT 140 exhibits a 9.6 GTexel/s better Texture Fill Rate than the GT 730. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GT 730 has a 50 MHz higher core clock speed than the GeForce GT 140, but the GeForce GT 140 has 12 more Render Output Units than the GT 730. As a result, the GeForce GT 140 exhibits a 7.6 GPixel/s better Pixel Fill Rate than the GT 730. 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 GeForce GT 140, 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 GeForce GT 140 when running the latest games.

The GT 730 has 1024 MB more video memory than the GeForce GT 140, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the GeForce GT 140 has superior memory performance.

The GeForce GT 140 has 28.8 GB/sec greater memory bandwidth than the GT 730, which means that the memory performance of the GeForce GT 140 is slightly better than the GT 730.

The GeForce GT 730 v3 Gigabyte 2GB Edition has 96 Shader Processing Units and the GeForce GT 140 has 64. However, the actual shader performance of the GT 730 is 134 and the actual shader performance of the GeForce GT 140 is 104. The GT 730 having 30 better shader performance is not particularly notable, as altogether the GeForce GT 140 performs better when taking into account other relevant data.

The GT 730 transistor size technology is 15 nm (nanometers) smaller than the GeForce GT 140. This means that the GT 730 is expected to run slightly cooler and achieve higher clock frequencies than the GeForce GT 140. While they exhibit similar graphical performance, the GT 730 should consume less power than the GeForce GT 140.

The GeForce GT 730 v3 Gigabyte 2GB Edition requires 49 Watts to run and the GeForce GT 140 requires 105 Watts. We would recommend a PSU with at least 300 Watts for the GT 730 and a PSU with at least 400 Watts for the GeForce GT 140. The GeForce GT 140 requires 56 Watts more than the GT 730 to run. The difference is significant enough that the GeForce GT 140 may have an adverse affect on your yearly electricity bills in comparison to the GT 730.
