In terms of overall gaming performance, the graphical capabilities of the Intel HD Graphics Desktop (Ivy Bridge) are significantly better than the Intel G43 Express Chipset.

The Graphics Desktop was released over three years more recently than the G43 Express Chipset, and so the Graphics Desktop is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the G43 Express Chipset 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 HD Graphics Desktop (Ivy Bridge) and the G43 Express Chipset have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The Graphics Desktop has 25.6 GB/sec greater memory bandwidth than the G43 Express Chipset, which means that the memory performance of the Graphics Desktop is slightly better than the G43 Express Chipset.

The Graphics Desktop has 6 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 HD Graphics Desktop (Ivy Bridge) requires 45 Watts to run and the G43 Express Chipset requires 24 Watts. The Graphics Desktop requires 21 Watts more than the G43 Express Chipset to run. The difference is not significant enough for the Graphics Desktop to have a noticeably larger impact on your yearly electricity bills than the G43 Express Chipset.
