The Raspberry Pi foundation has spent the last year filling out the Pi 5 lineup—in August, we got a cheaper $50 version with 2GB of RAM, and in December, we got the Pi 500, a Pi-inside-a-keyboard intended specifically for general-purpose desktop use. Today, the Pi 5 board achieves what may be its final form: a version with 16GB of RAM, available for $120.

The 16GB version of the Pi 5 includes the revised "d0" stepping of the Pi 5's BCM2712 processor. For the Pi's purposes, this chip is functionally identical to the original version but uses slightly less power and runs slightly cooler because it cuts out silicon used for features that the Pi 5 didn't take advantage of.

Raspberry Pi CEO Eben Upton writes that the 16GB version of the Pi 5 is possible because of other tweaks made to the d0 stepping of the Pi 5's processor, plus an updated LPDDR4X chip from Micron that could fit eight 16 Gbit RAM dies inside a single package that could fit on the Pi 5's board.

One of the selling points of the Raspberry Pi 5 (released in October 2023) is that it was fast enough and had enough memory to be a credible general-purpose desktop PC, if not an especially fast one. For Pi-as-desktop enthusiasts, the company has a couple of new pre-holiday announcements. The biggest is the Raspberry Pi 500, which fits the components of an 8GB Pi 5 into a small keyboard-shaped case for $90.

It's a follow-up to the original Raspberry Pi 400, and like that system, it takes the components from the regular Pi 5 board and puts them on a different PCB with all of the ports positioned in a single row across the back of the device. It includes one USB 2.0 port, two USB 3.0 ports, a microSD slot, two micro HDMI ports, the 40-pin GPIO header, and a gigabit Ethernet port.

In addition to the standalone $90 system, the Pi 500 will also be sold as part of a Desktop Kit with a mouse, power supply, HDMI cable, and printed Beginner's Guide booklet for $120.
