Cheapest laptop that can run Fusion ?
What sort of toolpaths are you using? Generating toolpaths can use more resources than design! If you generate a large 3d toolpath Fusion will use all your cores and all the GHz your CPU can provide. On the specs page for Fusion it does say you can use the integrated cards but they can dynamically allocate upto 50% of your memory. Again toolpath generation can need more memory than design so I'd say 16Gb minimum. So really you have it a bit backwards, CAM can need a more powerful computer than design.
To help with graphics if you go for integrated turn off all the effects, I turn these off anyway as I never add appearances and just find the effects distracting.

I've been helping someone with the same GPU here. Fusion was complaining about the GPU, “This computer graphics driver or hardware may be limiting performance”. Setting the minimum memory allocated to the card in the BIOS got rid of the error but not sure about performance. Might be worth asking in that thread.
I notice on the specs the base frequency is 2.3GHz with a boost to 4.2GHz. I seem to remember there being a limit on threads if at max boost for some CPUs, think there's a setting to work around that. You might want to research a bit on this as high clock speed is going to be important.
Just found this in AMD website.

Not sure how much of a problem the lower clock speed will be when all cores are in use. If you have task manager running when you generate a program you normally get one thread work for a few seconds then all cores but then it goes back to one core again. So if the high clock speed helps with the start and end of the calculation and all cores with the middle part it might actually work well. Think good ventilation will help so you might want a laptop cool pad as well.
Do you use the the In Process Stock option? I find it takes too long when working on 3d parts but it does look like it does use all cores as well.

so i've been playin around a bit on my 6core/12thread core i7-8700 with generating toolpaths to see how the cores are used. Have to do a comparison on windows but at least on mac the multi cores and multithreading are pretty well used for toolpath calculations but overall compared to rendering none of the cores/threads are working full steam. did a ridiculous adpative clearing operation on a large complex 3d object with stupid small stepdown and no rest machining (machining this would have been 13h machine time 😂) for analysis.
In the beginning before the toolpaths start drawing this is how it looks:
then towards the middle when the toolpaths start drawing:
and it fizzles out a bit after that when most of the toolpaths are displayed:
when rendering the same object however it's full steam ahead on all pipes:
i think the GPU activity monitor can't be trusted since it's a hackintosh and this particular graphics card is not really supported.
so i guess the graphics card question (iGPU or discrete graphics card) is only partly relevant and hopefully the newer gen cpus built in graphics will all be able to at least run Fusion (since i won't be modeling or rendering at all on the laptop but only pan around the model a bit).
I forgot to run some test of simulating which would be usefull on site as well, but i think i'll switch to Windows to do these tests again ehich will be more relevant.
A good test for core utilisation would be create a setup with roughing and finishing ops and regen all the ops in the setup. Don't use rest machining because Fusion will wait for previous ops to finish.
When you say test simulation do you mean in manufacturing? Sim seems to be mostly CPU, very low GPU.
Do you work with appearances and all the visuail bells and whistles enabled? I don't like working with any of that, just press Ctrl+N for colour cycling and everything turned off. Just testing on an old PC with a NVidia GTX 660 with a fairly big assembly (for me) and don't see more than 20% most of the time. If I zoom in so the model takes up the whole screen it gets upto 50% but you don't tend to work like that. Weird thing is while moving the model around the CPU jumps to max boost!

I've never understood this either, same with TVs! Looks good when they're switch off, useless when using them. Probably for people who buy speakers based on what they look like rather than how they sound.🙄
