You won't have to find some totally legit sources in order to download more RAM for your Raspberry Pi 4 anytime soon, as a new version of the Pi 4 B has been announced. With the unit's first anniversary just around the corner, a premium model has been introduced, featuring a whopping 8GB of RAM. That's double the amount of the previous "high-end" $55 4GB model, all packed neatly into that familiar size for $75, available starting today. The extra RAM doesn't change much of the Pi 4's board, though this version does sport a new power switcher that's closer to the USB-C input, otherwise leaving the rest of the internals the same as before.
To supply the slightly higher peak currents required by the new memory package, James has shuffled the power supply components on the board, removing a switch-mode power supply from the right-hand side of the board next to the USB 2.0 sockets and adding a new switcher next to the USB-C power connnector. While this was a necessary change, it ended up costing us a three-month slip, as COVID-19 disrupted the supply of inductors from the Far East.
To coincide with this new release, the Raspbian OS, now simply renamed to the Raspberry Pi OS, offers a 64-bit version currently in beta and available to download through their official site.
