On the subject of RAM, keep in mind that the (integrated) graphics performance is heavily tied to the total bandwidth of your RAM, so having 2 sticks is going to help even if it were the exact same capacity as a single stick.
And of course, faster speed RAM farther helps things (though XMP being uncommon on laptops makes things a bit tricky - the safest bet is that loose timings e.g. CL19 for DDR4-3200 likely means it doesn’t require XMP)
