DDR4 is slightly older technology compared to DDR5, hence the number... duh....

I would suggest to go for DDR5, since its a newer technology and faster in terms of speed. Furthermore, using DDR5 will somewhat ensure you are future proof in the event that DDR4 becomes obsolete, just like DDR3.


Hope this helps...

Yupe, that's the point... I believe going for DDR5 will future proof the laptop. But I suggest that you try with the existing RAM capacity first before upgrading, the system feels slow or laggy then only you decide whether to upgrade the RAM or not.

Sooner or later DDR4 will become obsolete.


Hope this helps...
