We are now half way 2022 so I have been stating this for a decade. ( Probably some old HN comments somewhere )

DRAM Cost / GB hasn't been getting any cheaper. ( Not adjusted for inflation ) Unlike NAND at cost per GB, or Consumer CPU cost per core ( not a fair comparison due to die size difference but relevant in this context ), hence it is an expensive component in terms of overall system. You get higher throughput, lower energy, but not lower cost. In fact your 8GB LPDDR5 in latest MB cost more than the 8GB in 2015 MBA even adjusted for inflation.

And there are no current roadmap to suggest we could break this trend. While we could and are continuing to shrink transistors, you can only do so much with capacitor inside the DRAM. Unless we have some fundamental breakthrough, this will remain the case for DRAM in the foreseeable future.

I still remember I was called out and attacked for suggesting this in ~2012. That machines in 2020s will remain at 8GB.

In October 2019 I bought two 32GB 2666MHz DDR4 SODIMMs for my laptop for $140 each.

You can now get a single 32GB DDR4 3200MHz SODIMM for under $120

Are you posting these links to suggest that the commenter is incorrect about prices remaining the same?

If so, I'm not sure comparing prices of DDR4 are the same thing, since the commenter was talking about LPDDR4.

* 64GB of 2666MHz DDR4 in 2019: $280

* 64GB of 3200Mhz DDR4 in 2022: $240

memory has been getting faster and cheaper, and it really wasn't that expensive to begin with.

I said cost not price.

You manage to pick the highest margin product with the biggest variation of pricing inside a commodity market to compare using two data point within a short period.

Compare this with CPU operations per second per dollar and it paints a totally different story
