In terms of overall gaming performance, the graphical capabilities of the Intel G43 Express Chipset are very slightly better than the Nvidia GeForce 9300 GS.

The G43 Express Chipset was released less than a year after the GeForce 9300 GS, 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 GeForce 9300 GS has 512 MB video memory, but the G43 Express Chipset does not have an entry, so the two GPUs cannot be reliably compared in this area.

Both the G43 Express Chipset and the GeForce 9300 GS have 0 Shader Processing Units. The two GPUs are based on different architectures, but deliver an equivalent shader performance. To compare, we must continue to look at the memory bandwidth, Texture and Pixel Rates. In this case, we sadly do not have enough data in this area to complete the comparison.

The G43 Express Chipset requires 24 Watts to run but there is no entry for the GeForce 9300 GS. We would recommend a PSU with at least 300 Watts for the GeForce 9300 GS, but we do not have a recommended PSU wattage for the G43 Express Chipset.
