Today Raspberry Pi introduces a new version of its popular line with a board computer. The Raspberry Pi 4 B is the fastest Raspberry Pi, with the company promising "desktop productivity comparable to the initial x86 PC systems."
The new model is based on the Broadcom BCM2711 SoC, which with four 1.5GHz Cortex A72 processor cores must be a big upgrade over the Cortex A53 quad-core processor in Raspberry Pi 3. The RAM options are an even bigger upgrade 1GB, 2GB and even 4GB DDR4 options. Pi 3 was limited to 1GB of RAM, which really lived up to desktop use
There were some upgrades and tweaks to Pi 4 I / O. Gigabit Ethernet returns as well as four USB ports but two of them get upgraded to USB 3.0. The power supply is now supplied via a USB-C port instead of the aging Micro USB of Pi 3. The headphone jack also returns what is still a four-pole solution providing audio and composite video.
An interesting choice is to remove the only HDMI port on Pi 3 in favor of two HDMI ports. Now Pi 4 will support two 4K monitors, but you will have to deal with the less widespread choice of cables. To push these displays, Raspberry Pi promises a lot of multimedia support: H.265 decoding for 4K60p, H.264 1080p60 decoding and 1080p30 encoding, and OpenGL ES 3.0 graphics.
The 40-pin GPIO head is fully compatible with the previous boards, so all your old hats have to work. Also for two cable connectors, which are still two-way MIPI DSI (Display Serial Interface) and two-way MIPI CSI (Camera Serial Interface). The device still has 2.4GHz and 5GHz 802.11b / g / n / ac Wi-Fi while Bluetooth is upgraded to 5.0. As always, Pi has 0GB of storage. You will need to put a MicroSD card to load the operating system and run programs.
Just like Raspberry Pi 3, Pi 4 starts at $ 35 for the 1GB RAM version. Now there are higher levels with more RAM: 2GB for $ 45 and 4GB for $ 55. Raspberry Pi says Pi 4 will remain in production at least until January 2026
