The ARM SoC (system on chip) CPUs these boards use often cap out at supporting 4GB of RAM. It's also much more expensive and power hungry to stuff a bunch more DDR4 onto a tiny board, and often messes with the layout (i.e., of you need two RAM chips instead of one).
The rk3399 CPU on this board also dates from 2016[^1] so adjust your expectations accordingly. :)
[^1] It's also a well-documented chip that's cheap, provides a nice performance bump over an RPi, and requires fewer proprietary blobs.

[1] "4x Cortex-A76 and 4x Cortex-A55 cores" (should be much faster than the RPi4), some kind of NPU (don't know the specs). Not sure about I/O, but I'd guess it'd be at least as good as the rk3399 is.

- 3np 6y agoPine64 announced recently it will be their base SoC for new products, with the first one being an SBC.
- scottlamb 6y agoThanks for the pointer. Just looked. This announcement [1] says the rk3566a, which isn't quite as fancy. Still looks like a nice board. People on the message boards back in March [2] were guessing there won't be an rk3399-based Pine64 until early 2022. :-( [1] https://www.pine64.org/2020/11/15/november-update-kde-pinephone-ce-and-a-peek-into-the-future/ https://www.pine64.org/2020/11/15/november-update-kde-pineph...
