In terms of overall gaming performance, the graphical capabilities of the Intel G43 Express Chipset are massively better than the Intel 865G.

The G43 Express Chipset was released over three years more recently than the 865G, and so the G43 Express Chipset is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the 865G 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 865G has 16 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 865G and the G43 Express Chipset 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 865G requires 13 Watts to run and the G43 Express Chipset requires 24 Watts. The G43 Express Chipset requires 11 Watts more than the 865G to run. The difference is not significant enough for the G43 Express Chipset to have a noticeably larger impact on your yearly electricity bills than the 865G.
