Re: New laptop to play Sims 4 on
@Andja03 At a 1920x1080 resolution, a GTX 1650 is faster than an RTX 2050, so the 1650 is the better choice for this class of laptop. The 1650 should be able to run all Sims 4 packs together on ultra settings, although you might need to drop some settings down to high if you like to use high poly custom content. It's fine to experiment with the settings too.
All of the processors you've listed are capable of driving a much faster GPU than the 1650, so they're all fine. I would suggest as tie-breakers (aside from price) that you consider the release date of the CPU, as that will determine, roughly speaking, how long the laptop will get driver support, as well as give you some idea of how old it is. It's not a perfect measurement, but it's worth considering.
The other important factor for the processor is the turbo speed, but this is not a one-to-one comparison either because CPUs get more efficient with every generation. Thus a CPU from four years ago running at 4.5 GHz is probably slower than a brand-new one with the same number of cores running at 4.2 GHz. You don't need to spend too much time thinking about this because anything paired with a 1650 or 2050 will at least be good enough, but if for example you can choose between a 9750H and a 12450H, the latter is clearly faster even though it's an i5 with a slightly lower turbo speed. But the 9750H is fine; this is about choosing among multiple good options.
Core count doesn't matter at all past 6 because Sims 4 can only use 4 cores. Even 4 is enough if you're not multitasking—Windows processes don't use much power at all when idle.
For the RAM, it is of course better to get 16 GB, but don't pass up an otherwise-perfect laptop because it only has 8. Memory is cheap, and in a gaming laptop, almost always simple to install, so you can add another 8 GB module down the road if you want. In the interim, 8 GB is enough for a laptop that has a dedicated card and therefore separate video memory. I'd suggest not running much alongside the game though, just to keep resource use relatively low; restarting the laptop before playing is going to be helpful here.
