Thank you; that's the exact anecdotal and unscientific information I was after as a starting point. That confirms it's possible, and worth further investigation by those who want deeper or more refined analysis.Using one of the 5v USB sockets on our chart table that do power a 400 quite successfully, I got power warnings on the screen and vcgencmd get_throttled gave me 0x5000. vkcube still ran; not perceptibly slower and so did web browsing, also; not perceptibly slower; which suggest to me that even throttled the Pi5 is fast in practical terms. Most importantly...it still ran!!
That makes me confident I can swap my Pi 3B board out of the set-top box I have and drop a bare Pi 5B in without changing anything else and it will work. I should be able to take advantage of that upgrade even if I do have to do some post-upgrade tweaking. I would likely add an Active Cooler if I were to do that.2.02 Amps for the 400 and 2.08 Amps for the Pi5. (Voltage was 5.09V)
That came from details on cooling and running a Pi5 without any heatsink -I've read elsewhere that the Pi5 throttled is actually still faster than the Pi4; unthrottled...Maybe someone else can confirm if that's true or not?
For normal usage of your Raspberry Pi, adding cooling is entirely optional ... However, a heavy continuous load will mean that the board could potentially go into thermal throttling ... Although, even when fully throttled, a Raspberry Pi 5 is still going to run faster than a Raspberry Pi 4!
