DDR4 is not being manufactured at scale any more so it’s becoming very expensive too.

> if they had gone with DDR5 it would have doubled

They charge a premium for their hardware due to the software. They have plenty of room for RAM price fluctuations. It would nowhere near double the price.

I know you’re joking, but anything DDR3 based is really slow and power inefficient relative to current gen hardware.
