In terms of overall gaming performance, the graphical capabilities of the Intel G43 Express Chipset are significantly better than the Nvidia GeForce 8100 nForce 720a.

The G43 Express Chipset was released over a year more recently than the 8100 nForce, and so the G43 Express Chipset is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the 8100 nForce.

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 G43 Express Chipset and the GeForce 8100 nForce 720a have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The memory bandwidth of the G43 Express Chipset and the GeForce 8100 nForce 720a are the same, which means the G43 Express Chipset and the 8100 nForce have equal limitations when it comes to graphical data transfer.

The 8100 nForce has 8 Shader Processing Units but the G43 Express Chipset does not have an entry, so the two GPUs cannot be reliably compared in this area.

The G43 Express Chipset requires 24 Watts to run but there is no entry for the GeForce 8100 nForce 720a.
