Buying a gaming laptop? Check the memory density!

A couple of interesting videos discussing memory density and laptop performance. Although this issue affects desktop memory too, the issue is much more prevelent in laptops.
In short, sticks with x8 memory chips will outperform, often signifigantly, sticks with x16 memory chips, even when the chips are otherwise the same spec (rank, speed, and timings).


This LTT video compares two sets of modules that have the same specs and shows a 20+% performance uplift in certain scenarios with the x8 chip modules.

BZD's video goes into a bit of detail about why the performance increase/decrease exists.
