Almost a year after the Pi 4 went on sale, the Raspberry Pi Foundation has doubled the maximum memory option to 8 GB, while also renaming the default operating system and releasing a 64-bit beta OS image.

The Foundation says that although the Broadcom chip at the heart of the Pi 4 can handle up to 16 GB of LPDDR4 RAM, up until recently 8 GB LPDDR4 modules that could be used on the mini computer didn't exist. Micron developed just such a module earlier this year, but COVID-19 stepped in to disrupt the supply chain for another vital component and the release was put back for three months.

Aside from having to move power supply components around fixing bugs and adding features, the mini computer is pretty much the same as before. A tour around the board will reveal a 64-bit BCM2711 quad-core Cortex-A72 system-on-chip, 802.11ac dual-band Wi-Fi and Bluetooth 5.0 wireless comms, Gigabit Ethernet, two USB 3.0 and two USB 2.0 ports, two micro-HDMI ports capable of supporting 4K monitors, a display port and a camera port, the standard 40-pin GPIO header, and a microSD card slot for data storage and loading the operating system.

Up until now, the default operating system has made use of a 32-bit kernel and 32-bit userland. Change is in the air now though, as the Foundation has recognized the needs of power users and released an early beta of a 64-bit operating system image. Both the 32-bit and 64-bit OS images also get a Desktop update, and will now go under the Raspberry Pi OS moniker instead of Raspbian.

All of this means that makers can now throw more demanding workloads at the Pi 4, and make use of more powerful applications. The 2 GB version of the Pi 4 is priced at US$35, the 4 GB comes in at $55, and the new 8 GB model costs $75 and is available now.

Awesome. RPi4 is truly catching up to the copycats - and keeping their price range sensible! I've liked RPi since RPi2 but have been limited in any real networked use by the corners cut to keep price down. USB2.0, 10/100 ethernet connection, no real onboard storage other than your SD card. You always had to add a hat - and the hat further limited your usage while it gave you a desired capacity. Glad to see this!
