In terms of overall gaming performance, the graphical capabilities of the Intel GM45 Express Chipset are massively better than the Nvidia GeForce 8200M G.

The GM45 Express Chipset was released less than a year after the GeForce 8200M G, and so they are likely to have similar driver support for optimizing performance when running the latest games.

Both GPUs exhibit very poor performance, so rather than upgrading from one to the other you should consider looking at more powerful GPUs. Neither of these will be able to run the latest games in any playable way.

The GM45 Express Chipset and the GeForce 8200M G have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The GM45 Express Chipset has 17.1 GB/sec greater memory bandwidth than the GeForce 8200M G, which means that the memory performance of the GM45 Express Chipset is slightly better than the GeForce 8200M G.

The GM45 Express Chipset has 10 Shader Processing Units and the GeForce 8200M G has 8. However, the actual shader performance of the GM45 Express Chipset is 5 and the actual shader performance of the GeForce 8200M G is 3. The GM45 Express Chipset having 2 better shader performance and an altogether better performance when taking into account other relevant data means that the GM45 Express Chipset delivers a marginally smoother and more efficient experience when processing graphical data than the GeForce 8200M G.

The GM45 Express Chipset requires 12 Watts to run but there is no entry for the GeForce 8200M G.
