> The BCM2711 chip that we use on Raspberry Pi 4 can address up to 16GB of LPDDR4 SDRAM, so the real barrier to our offering a larger-memory variant was the lack of an 8GB LPDDR4 package. These didn’t exist (at least in a form that we could address) in 2019, but happily our partners at Micron stepped up earlier this year with a suitable part.
All other SBCs in this market segments have also been capped at 4GB - I'm hopeful about this leading to larger memory options from other vendors as well before long.

Great of RPi to keep pushing the envelope.
