In terms of overall gaming performance, the graphical capabilities of the Intel HD i5 660 are significantly better than the Intel Q43 Express Chipset.

The HD i5 660 was released over a year more recently than the Q43 Express Chipset, and so the HD i5 660 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.

Neither the Q43 Express Chipset nor the HD i5 660 have an entry for video memory, so the two GPUs cannot be compared in this area.

Both the Q43 Express Chipset and the HD i5 660 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 HD i5 660 requires 73 Watts to run but there is no entry for the Q43 Express Chipset.
