Raspberry Pi 4: Dual-4K displays, Gigabit Ethernet, 2 USB 3.0 ports and More…

"This is a comprehensive upgrade, touching almost every element of the platform."

By CBR Staff Writer

Tech junkies, hackers and educators have a brand new toy to play with today as the Raspberry Pi Foundation drops its latest model, the Raspberry Pi 4, and to be honest it’s a bit of a beast, writes Computer Business Review’s Conor Reynolds. 

The new Raspberry Pi 4 Model B showcases a significant jump in performance in comparison to previous versions. The Pi 4 is built around a Broadcom BCM2711 system-on-chip and has a 1.5GHz quad-core 64-bit ARM Cortex-A72 CPU.

This new model now comes with a 4GB option that many will welcome following the 1GB limitation of the Pi 3B+ model, dual-4K displays, 4K60 H.265 video decode, gigabit Ethernet and two USB 3.0 ports. In terms of performance  – depending on what you ask it to do  – the Pi 4 should be two to three times faster than the last version.

The Pi 4 comes with a few connection changes that promise to simultaneously delight and annoy Pi fans across the board, as they have gotten rid of the type-A (full-size) HDMI connector. Instead it has been replace with a two type-D (micro) HDMI connectors. This is in order to accommodate a duel display output that the Pi team says is capable of running two 4K video outputs at 60 FPS.

Fans of the Raspberry Pi series will find themselves looking through the cable box as the Pi design team have swapped out the USB micro-B power connection for a standard USB-C connector.

The Raspberry Pi team notes in a blog that “All three connectors on the right-hand side of the board overhang the edge by an additional millimetre, with the aim of simplifying case design. In all other respects, the connector and mounting hole layout remains the same, ensuring compatibility with existing HATs and other accessories.”

“Our Gigabit Ethernet magjack has moved to the top right of the board, from the bottom right, greatly simplifying PCB routing. The 4-pin Power-over-Ethernet (PoE) connector remains in the same location, so Raspberry Pi 4 remains compatible with the PoE HAT.”

Today’s launch comes with three flavours of memory 1GB, 2GB or a chunky 4GB. The Pi have noted that for the initial release they have manufactured more of the 2GB version.

The one you select really depends on what you want to do: for instance if you want to run the new 4K dual screen option then the 4GB may be required. As well as a new 4GB option the Pi 4 has moved from the memory transfer speed standard LPDDR2 to LPDDR4.

To run the Raspberry Pi 4 the team have created what they call a ‘radically overhauled operating system’, which will be based on the Debian 10 Buster release.

The system will now have a modern looking user interface and will be able to access updated applications like Chromium 74 web browser.

The Pi 4 requires that you update drivers for Raspbian.

On sale today, the Pi 4 1GB is £28, 2GB for £35 and the 4GB will set you back £44, but the pocket-sized powerhouse is selling out widely.
