In terms of overall gaming performance, the graphical capabilities of the Nvidia Quadro K620 are noticeably better than the Nvidia GeForce GT 730 v3 Gigabyte 2GB Edition.

The GT 730 has a 33 MHz higher core clock speed than the Quadro K620, but the Quadro K620 has 16 more Texture Mapping Units than the GT 730. As a result, the Quadro K620 exhibits a 10.1 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 33 MHz higher core clock speed than the Quadro K620, but the Quadro K620 has 12 more Render Output Units than the GT 730. As a result, the Quadro K620 exhibits a 7.9 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 Quadro K620 was released less than a year after the GT 730, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The GT 730 has 1024 MB more video memory than the Quadro K620, 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 memory bandwidth of the GeForce GT 730 v3 Gigabyte 2GB Edition and the Quadro K620 are the same, which means the GT 730 and the Quadro K620 have equal limitations when it comes to graphical data transfer.

The GeForce GT 730 v3 Gigabyte 2GB Edition has 96 Shader Processing Units and the Quadro K620 has 384. However, the actual shader performance of the GT 730 is 134 and the actual shader performance of the Quadro K620 is 346. The Quadro K620 having 212 better shader performance and an altogether better performance when taking into account other relevant data means that the Quadro K620 delivers a marginally smoother and more efficient experience when processing graphical data than the GT 730.

The Quadro K620 transistor size technology is 12 nm (nanometers) smaller than the GT 730. This means that the Quadro K620 is expected to run slightly cooler and achieve higher clock frequencies than the GT 730.

The GeForce GT 730 v3 Gigabyte 2GB Edition requires 49 Watts to run and the Quadro K620 requires 45 Watts. We would recommend a PSU with at least 300 Watts for the GT 730 and a PSU with at least 350 Watts for the Quadro K620. The GT 730 requires 4 Watts more than the Quadro K620 to run. The difference is not significant enough for the GT 730 to have a noticeably larger impact on your yearly electricity bills than the Quadro K620.
