Switching off DDR3 manufacturing I can understand, but DDR4 machines are still quite relevant and usable… Ryzen 5000 series boxes for example don’t feel meaningfully weaker than they did when new. My 5950X tower certainly doesn’t, and it’d really be nice to be able to upgrade its RAM should I need to because it will continue to be useful for quite some time.
AMD just re-released their 5800X3D for AM4 board users who wish to upgrade which is further evidence that shutting off DDR4 production is premature.
They're running a business not a charity. Their job is to manufacture what the market as a whole demands. If they can make more money making HBM than DDR4 then they have to make HBM. Why would a business go out of its way to make less money?
1. The AI bubble is an insane distortion and the gravy train isn’t going to last forever. Betting the farm on everlasting datacenter demand is myopic.
2. In a healthy, competitive market there would be smaller manufacturers that’d be happy to take up the big guys’ discarded business.
1. But it might last for at least few more years, see Nvidia 1 trillion backlog.
2. Semiconductor manufacturing is the most complex industrial process in the world. You need billions of capex and decades of experience. Even existing semi players like intel cannot switch production to memory.
China CXMT is gaing traction in DDR market. New fabs from all players wil come online in the next two years.
People will remember these shenanigans and will buy Apple after getting ripped off by PC manufacturers.
