I... ok.
Am I an idiot, or... at least when it comes to system RAM...
Do you really need DDR5 RAM, instead of DDR4?
Like, say I have 32 GB or DDR4 vs 32GB of DDR5.
Beyond I guess crushing some benchmark software harder... what are the actual practical benefits of this?
For an average person?
What can I do with 32 gigs of DDR5 that I can't do with 32 gigs of DDR4? Or 16? Or 24?
Typically the CPU and motherboard are both tied to a specific generation of RAM, which is keyed and traced differently on the motherboard for DDR 4 vs 5.
For example the current AMD socket AM5 requires DDR 5. You’d have to go back to AM4 Ryzen 5000 series for DDR 4 support.
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.
