Dell and Lenovo may limit mid-range laptops to 8GB DDR5 RAM in response to rising memory prices

This is a most excellent place for technology news and articles.
I mean... I know that...
But my question still stands.
Ceteris paribus, keep as much else the same, same GPU, similar CPU by benchmark scores... swap the mobo and the sys ram...
What do you actually gain by going from DDR4 to DDR5, in total, end-state capabilities?
DDR5 is faster.
What kinda stuff actually needs that being faster, actually benefits from it?
IGPs are very dependant on memory speed. Many uses gains from faster memory speed (but I can't give you one out of memory), but most games gains more from memory latency than raw speed (with some exception, like Stellaris).
Usually, if your app is CPU heavy, you'll gain from RAM speed.
