I wonder why RK3566 and even RK3228A TV boxes come with 8GB RAM, but the vastly superior RK3399 is only ever seen with 4GB.
Also, this may interest some people here (whoops if already posted).
It's a random(?) putting what appears to be a @balbes150's RK3566 build on X96 X6, a 8GB TV box, and claiming that even WiFi/Bluetooth works? Unclear.
