In terms of overall gaming performance, the graphical capabilities of the Intel HD i3 540 are significantly better than the Intel Q43 Express Chipset.

The HD i3 540 was released over a year more recently than the Q43 Express Chipset, and so the HD i3 540 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the Q43 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 Q43 Express Chipset and the HD i3 540 have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The HD i3 540 has 10.7 GB/sec greater memory bandwidth than the Q43 Express Chipset, which means that the memory performance of the HD i3 540 is slightly better than the Q43 Express Chipset.

Both the Q43 Express Chipset and the HD i3 540 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.
