Because the factories are already set up to make DDR4. Retooling to make DDR5 will cost a lot of money and take a lot of downtime for which the factory isn’t making anything. So the companies are extending the life cycle of the DDR4 production lines, without needing to upgrade things or retrain workers. As long as people are buying it, then there’s money to be made by staying open.
It’s like being the burger restaurant next to the steak restaurant when the line for the steak restaurant is 3 hours long. You’ll get a lot of spillover from people who don’t want to wait, and you can benefit from that without necessarily turning into a steak restaurant yourself.
Wrong, memory companies have moved on to DDR5, they need to retool back yo to reproduce DDR4. The only problem is the semi fabs sold out of the ddr5 chips to AI companies for their builds.
The foundries still have the process in place for making DDR4, so since there’s demand they will keep making the product. It costs money to replace the machines in the facility to switch it to ddr5 or hbm, so the math only makes sense for a little while longer.
That is not consistent with what the person above said. They contended that manufacturers don’t want to produce DDR5 “because AI companies will buy it all”. I’m saying that is an incentive to produce DDR5; manufacturers don’t particularly care who buys their products.
You say “it’s a bubble that will pop” and that’s a valid explanation for the behaviour, but it’s a different explanation than the OP’s: you’re not saying “yeah, they don’t wanna do it because they don’t wanna sell to AI companies” you’re saying, “they don’t wanna do it because the demand isn’t robust”.
AI is taking all the supply for the latest and greatest. All the production for DDR4 based stuff probably can’t do DDR5, so why not have it keep pumping out DDR4? It takes a LONG time to build out fabs for the latest and greatest so it’s not like they can switch to DDR5 stuff overnight.
Can someone that explain this to me? Why are companies choosing to make older parts available again instead of just making the new shit?
DDR4 slower therefore less demand from AI
Also run on older, cheaper process nodes that are not as volume constrained as high demand ddr5/hbm processes

Because if they just make more of the new stuff then the AI companies will just increase their order size and take it all. Their greed knows no bounds
That sounds like an incentive for the manufacturers to do it, so is not an explanation.
Not if they know it is a bubble that will pop and then they are holding the bag on all of that capex spent on ramping up the production

Why would they not want to produce for a market that has like >5x the profit margins of consumer grade stuff? They can’t make enough.
Exactly.

They were still making smaller amounts. They’re just turning up production.
