What we don't know is whether 4GB or 8GB Pis will get the tweaked chip design.

    The Pi 5 doesn’t require 5v 5amp. You just get limited power on downstream USB devices (like max 1 or 0.5 amp, not really that bad). It will run just fine on 3 amp PSU.

      It will not. It needs 5a under load. Else there would not be a 5a PSU required.

        https://www.raspberrypi.com/documentation/computers/getting-started.html

        Raspberry Pi 5 5V/5A, 5V/3A limits peripherals to 600mA

        5 amp is not a requirement, just a suggestion.

          5amp is a requirement. It will crash under load without it.

          I know because I have personally experienced this.

            Something is wrong with either your power supply, the cable, or the pi itself. Are you running any hats or any extra hardware? Mine runs just fine on a 3 amp power supply under full load.

              Nothing but the bare pi and heatsink. Some full loads are fuller than others. In my case I tried running some tflite stuff.
