Higher DRAM prices might mean that there is less demand from new system builders mean depressed prices so it might be more tempting to upgrade your existing AM5 CPU to Zen 6
> less demand from new system builders mean depressed prices
Only if they overestimate demand and overproduce CPUs. Otherwise it will lead to higher prices because there's less economy of scale.
I would figure the opposite. There are plenty of people like me staying on AM4 because of the RAM price increases. I will probably skip AM5 entirely.
