In terms of overall gaming performance, the graphical capabilities of the Intel GMA HD are significantly better than the Intel G43 Express Chipset.

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

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 GMA HD 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 GMA HD are the same, which means the G43 Express Chipset and the GMA HD have equal limitations when it comes to graphical data transfer.

Both the G43 Express Chipset and the GMA HD 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 and the GMA HD requires 45 Watts. The GMA HD requires 21 Watts more than the G43 Express Chipset to run. The difference is not significant enough for the GMA HD to have a noticeably larger impact on your yearly electricity bills than the G43 Express Chipset.
