Today, Raspberry Pi introduces a new version of its popular single board computer series. The Raspberry Pi 4 Model B is the fastest Raspberry Pi ever. The company promises desktop performance comparable to x86 PC entry-level systems.
The new model, based on a Broadcom BCM2711 SoC with four 1.5 GHz Cortex A72 CPU cores, should be a major upgrade from the four cores Cortex A53 CPU in the Raspberry Pi 3. However, the RAM options are the even bigger upgrade with options for 1GB, 2GB and even 4GB DDR4. The Pi 3 was limited to 1 GB of RAM, which was unbearable for desktop use cases.
There have also been some upgrades and improvements to the Pi 4 I / O. Gigabit Ethernet is returning, as are the four USB ports, but two are upgraded to USB 3.0. Power is now supplied through a USB-C port instead of the obsolete Micro-USB port on the Pi 3. The headphone jack also returns, and continues to be a four-pin audio and composite video solution.
An interesting choice is the removal of the single full-size HDMI port of the Pi 3 in favor of two micro-HDMI ports. The Pi 4 now supports two 4K monitors, but you need to be aware of the less ubiquitous cable choices. Raspberry Pi offers many multimedia features: H.265 decoding for 4K60p, H.264 1080p60 decoding and 1080p30 encoding, and OpenGL ES 3.0 graphics.
The 40-pin GPIO header is fully backwards compatible with previous boards, so all your old hats should work. The same applies to the flexible two cable connections, which are still a two-lane MIPI DSI (Display Serial Interface) and a two-lane MIPI CSI (Camera Serial Interface). The device also has 2.4GHz and 5GHz 802.11b / g / n / ac Wi-Fi, while Bluetooth has been upgraded to 5.0. As always, the Pi has 0 GB of memory. You must insert a microSD card to load an operating system and run programs.
Just like the Raspberry Pi 3, the Pi 4 for the version with 1 GB RAM costs 35 USD. There are now higher levels with more RAM: 2 GB for 45 USD and 4 GB for 55 USD. According to Raspberry Pi, the Pi 4 will remain in production at least until January 2026.
