38 There may be better set-top boxes for the total cost of RPi + peripherals you
39 would need to run it, but I have not looked into ARM embedded options for some
40 time now. For routers and high throughput miniservers I prefer amd64
41 embedded, which cope much better esp. with AES-NI hardware encryption
42 processing.
43
44 Anyway, according to the man behind RPi 16G is upper limit of what this BCM
45 SoC can run theoretically, but:
46
47 "There really, really isn't a 16GB package that we could use, or a way to use
48 a pair of packages ..."

51
52 I would think even if fatter RAM modules could fit on the board, power supply
53 and cooling issues would introduce other design constraints and also push the
54 price point above the market segment RPi are targetting.
