7745hx is for high end gaming laptop, with dedicated dGPU and no mobility use. 7840hs has very good iGPU and still is powerfull enough, say 10% less. And perf/watt is far better. It also has IA NPU for potential gadget video effects. Definitively I would go for 7840hs

I think 7845 is intended to be used with dGPU only, hence the 610M only iGPU. It is definitively not intended to play on battery and targets high end laptops for big software or gaming with high end dGPU only. Most people would prefer 7840hs which is more balanced.

The PCIe 5.0 would be the reason to choose the 7745hx, I assume it will boost the SSD read and write when upgrading to a PCIE 5.0?

This average operating temperature will be much lower than 7840 hs. So 7745hx is hard to choose. Especially since it's a laptop.

I'm not quite sure about the purpose of the 7745HX. It seems to be redundant when compared to the 7840HS, except that the latter at least possesses a highly capable integrated GPU. For some reason, the 7745HX opts for the 610m, which doesn't seem to add much value.
