HBM4 and HBM4E DRAM are NOT the DDR4/5 that consumer markets need. Capacity allocation is leaning more to data center grade HBMs so less to produce dedicated DDR4/5 DRAMs. Supply demand will further drive up the consumer DRAM price! Note, the article mentions NO of new fabs is being constructed (all semiconductor manufacturers know that constructing more fabs means the boom/burst cycle will eventually kill them, so no one create more fabs) Perhaps the federal government need to step in here - the market doesn't fit the issue.

Plus it takes 3x the wafer capacity for hbm than the same byte capacity in dram, so we’ll likely see the consumer market be decimated here

HBM can be used for GPU though. I wish it was more common.

Might lower the prices of Mac Minis, Studios etc though
