With the Raspberry Pi 4, the Raspberry Pi Foundation brings a new version of the single-board computer, which enjoys great popularity, especially among hobbyists. The various innovations are likely to be very popular with many users, especially since a wide range of applications are possible. In the following, you will find out which adjustments have been made in detail and what else the new Raspi brings with it.

New technical basis

The heart of the Raspberry Pi 4 is the Broadcom BCM2711 processor, which has four ARM Cortex-A72 cores with a maximum clock speed of 1.5 GHz. In addition, there is 1, 2 or 4 GB LP DDR4 RAM depending on the selected model. Thus, the RAM size can now be selected based on one's own needs, which has long been desired by the user community. Furthermore, the single-board computer has a VideoCore VI GPU, which can decode H.264 and H.265.

Faster connections

There are two USB 2.0 ports on the Raspberry Pi 4, but fortunately there are now also two USB 3.0 interfaces. Equally advantageous is that real Gigabit LAN is now available. Those who want to use the small device primarily as a multimedia player will be happy about the two micro-HDMI ports. A microSD card for the operating system can still be inserted and a USB-C interface is now used for the power supply.

In terms of wireless technologies, the Raspberry Pi 4 has also made a leap and is now capable of 802.11ac WLAN, so that either the 2.4 or 5 GHz frequency band can be used. Bluetooth version 5.0 is now included. Additional onboard ports allow the use of a display or a camera. Of course, the GPIO header is still available. Via PoE header is additionally the power supply via network possible.

Compatibility with the predecessor

As usual, the Raspberry Pi 4 is software-technically largely compatible with the previous version. Accordingly, the associated operating system Raspbian of the manufacturer remains for the time being at 32-bit. However, a 64-bit version would be desirable in the future, because only then the new processor cores and the HDMI ports can be fully utilized. Thus, for example, the encryption could be accelerated.


In comparison with its predecessor, the Rapsberry Pi 4 convinces already at first glance with the updated interfaces. Equally, however, the more current Cortex A72 cores of the processor are noticeable, which provides for a noticeable performance boost. The possible applications can hardly be overlooked, so you can ideally use the Raspberry Pi 4 as a server for various services, for example. Beyond that, numerous other projects are conceivable, especially since the small system only needs about 3.5 watts in idle mode.
