In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 9800M GT are significantly better than the Nvidia GeForce 9400M G.

The GeForce 9400M G was released less than a year after the GeForce 9800M GT, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The GeForce 9800M GT has 512 MB video memory, but the GeForce 9400M G does not have an entry, so the two GPUs cannot be reliably compared in this area.

The GeForce 9400M G has 16 Shader Processing Units and the GeForce 9800M GT has 96. However, the actual shader performance of the GeForce 9400M G is 7 and the actual shader performance of the GeForce 9800M GT is 120. The GeForce 9800M GT having 113 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce 9800M GT delivers a noticeably smoother and more efficient experience when processing graphical data than the GeForce 9400M G.

The GeForce 9400M G requires 12 Watts to run and the GeForce 9800M GT requires 65 Watts. The GeForce 9800M GT requires 53 Watts more than the GeForce 9400M G to run. The difference is significant enough that the GeForce 9800M GT may have an adverse affect on your yearly electricity bills in comparison to the GeForce 9400M G.
