For most users this isn’t a serious restriction, particularly since every tab in Chromium gets its own process. This allows multiple processes to share all 8GB of memory, subject to the restriction that no single process can use more than 3GB. Our default operating system image uses a 32-bit LPAE kernel and a 32-bit userland. Other than that, this is the same Raspberry Pi 4 you’ve come to know and love. New switcher, new inductors, new schedule 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 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. If you’re a power user, intending to compile and link large pieces of software or run heavy server workloads, or you simply want to be able to have even more browser tabs open at once, this is definitely the Raspberry Pi for you. To put it in retro-perspective (retrospective?), this is a BBC Micro‘s worth of memory for every bit in the memory of the BBC Micro it’s a little over 13,000 times the 640KB that Bill Gates supposedly thought should be enough for anyone (sadly, it looks as though this quote is apocryphal). It’s worth reflecting for a moment on what a vast quantity of memory 8GB really is.
