In terms of overall gaming performance, the graphical capabilities of the Q43 Express Chipset and the Q45 Express Chipset are equal.

Both the Q43 Express Chipset and the Q45 Express Chipset were released at the same time, so are likely to be quite similar.

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 Q45 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 memory bandwidth of the Q43 Express Chipset and the Q45 Express Chipset are the same, which means the Q43 Express Chipset and the Q45 Express Chipset have equal limitations when it comes to graphical data transfer.

Both the Q43 Express Chipset and the Q45 Express Chipset have 0 Shader Processing Units. Having the same number of SPUs and using the same architecture means that the performance they offer can be compared by looking at the memory bandwidth, Texture and Pixel Rates. In this case, the two GPUs have extremely similar stats, so any gaming performance difference would most likely be negligible.
