In some ways yes. Older designs on older nodes use older equipment- less precise, easier to build. There’s actually a lot of PC builders who are building machines on DDR4 mainboards because the memory is more affordable. A couple of DDR4 mainboards have been ‘un-discontinued’ as a result.
For a desktop or laptop PC, the difference of DDR4 to DDR5 often doesn’t make a huge difference. So you get a last-gen chipset and RAM and you get a decent machine without paying $thousands extra.
Would DDR4 or DDR3 be easier to produce?
