In terms of overall gaming performance, the graphical capabilities of the Intel G43 Express Chipset are significantly better than the Intel 945GM Express Family.

The G43 Express Chipset was released over three years more recently than the 945GM Express Family, 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 945GM Express Family 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 945GM Express Family has 128 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 945GM Express Family 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 945GM Express Family.
