@ColorMe2U Pets is clearly the most demanding pack; Seasons is second, also by a significant margin. IP and ITF are sort of on the same level, although IP is more graphically demanding, and ITF more CPU-intensive. Since your processor is reasonably strong, running ITF probably isn't as big an issue.
There are also steps you can take to mitigate the effects of those packs, other than ITF. For Pets, long-haired animals and horses have a larger effect than short-haired cats and dogs. Wild animals also take extra resources. So you could only play with short-haired pets, disable wild animals in the game options, and perhaps use a mod to prevent inactive families from adopting animals on their own.
For Seasons, rain, snow, and sleet are more demanding than other kinds of weather, so you could disable those in options, or else temporarily lower the graphics settings if you really want your sims to experience inclement weather.
For Island Paradise, there's less you can do, although the fog in IP definitely has an impact. But the world of IP is so broken anyway that it's not a good idea to play there unless you edit it or download a fixed version. The features of IP work fine in other worlds, as long as the water is deep enough, and the pack's content will still have a significant impact no matter what your settings are.
There are also many other steps you can take to improve performance overall independent of the packs you're running. This is a useful list:

And again, if your CPU and GPU temps get too high, all of this is moot, because the system will throttle performance to protect itself. So please make sure the laptop is properly cooling itself while you play. You can elevate it by putting books or something under the corners, use a laptop tray, or get a cooling pad.
At any rate, no matter which packs you install, keep an eye on temperatures and in-game framerates, and make an adjustment any time you notice an issue. If one of the demanding packs is too much for your laptop, just uninstall it. It's better to play smoothly with fewer packs than deal with crashing, lag, or other performance issues all the time.
