In terms of overall gaming performance, the graphical capabilities of the Nvidia Quadro K4200 are very slightly better than the Nvidia GeForce GTX 750 EVGA Superclocked 1GB Edition.

The GTX 750 has a 509 MHz higher core clock speed than the Quadro K4200, but the Quadro K4200 has 80 more Texture Mapping Units than the GTX 750. As a result, the Quadro K4200 exhibits a 40.2 GTexel/s better Texture Fill Rate than the GTX 750. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GTX 750 has a 509 MHz higher core clock speed than the Quadro K4200, but the Quadro K4200 has 16 more Render Output Units than the GTX 750. As a result, the Quadro K4200 exhibits a 3.2 GPixel/s better Pixel Fill Rate than the GTX 750. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The Quadro K4200 was released less than a year after the GTX 750, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The Quadro K4200 has 3072 MB more video memory than the GTX 750, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the Quadro K4200 also has superior memory performance overall.

The Quadro K4200 has 92.6 GB/sec greater memory bandwidth than the GTX 750, which means that the memory performance of the Quadro K4200 is massively better than the GTX 750.

The Quadro K4200 has 1344 Shader Processing Units and the GeForce GTX 750 EVGA Superclocked 1GB Edition has 512. However, the actual shader performance of the Quadro K4200 is 949 and the actual shader performance of the GTX 750 is 894. The Quadro K4200 having 55 better shader performance and an altogether better performance when taking into account other relevant data means that the Quadro K4200 delivers a massively smoother and more efficient experience when processing graphical data than the GTX 750.

The Quadro K4200 requires 108 Watts to run and the GeForce GTX 750 EVGA Superclocked 1GB Edition requires 55 Watts. We would recommend a PSU with at least 500 Watts for the Quadro K4200 and a PSU with at least 300 Watts for the GTX 750. The Quadro K4200 requires 53 Watts more than the GTX 750 to run. The difference is significant enough that the Quadro K4200 may have an adverse affect on your yearly electricity bills in comparison to the GTX 750.
