It'd be amazing if Raspberry Pi Foundation managed to make a model with 64-bit memory bus width instead of current 32-bit wide LPDDR4. RPi4 is heavily memory bandwidth limited.
Yeah, I know, cost. One can still wish. Perhaps it'll be feasible for RPi4+ or whatever the next upgrade is called.

- bitwize 7y agoNah fam. It's cool to write your text chat app or graphing calculator in Electron. Moore's Law will totally catch up and people won't miss the hundreds of MiB of RAM it takes up.
