DRAM Chip locations

Main question: What is the difference with RAM chip layouts?

I was looking at some Crucial DDR4 and comparing it to a Kingston DDR4 and I think I noticed that the Kingston had 8 large chips, while the Crucial had 4 larger chips (I can't be sure because the sticker covers them).

I can't seem to find an answer on google. I want to know if this is just an aesthetic thing, or whether it could actually make a difference.

All I know is that Kingston is manufactured in Taiwan and Crucial is Micron.

p.s I think Crucial is faster than the Kingston module, but I have no clue (I bought the Crucial, where the Kingston was the compatible one)

p.p.s There's more to this. I bought what may turn out to be the incorrect part for my laptop. So on a side note; are these two chips essentially the same/would they both work in the same laptop?
