The Raspberry Pi Foundation just announced the Raspberry Pi 4 and it’s amazing!
Physically, the Raspberry Pi 4 Model B is pretty similar in appearance to the Raspberry Pi 3 Model B+. It’s a single-board computer that is about the size of a deck of cards that has places to plug things in. There are some substantial differences though when it comes to what is actually on that board starting with the processor which now uses the Cortex-A72 architecture (quad-core 64-bit ARMv8 at 1.5GHz).
Gone is the single full-size HDMI port. In its place are two micro-HDMI ports capable of running two 4K displays at 60 frames per second. Being able to run a dual-monitor setup is great. Being able to run a 4K dual-monitor setup is simply awesome.
But that’s not the only change. For years the Raspberry Pi has been stuck at either 512MB or 1GB of RAM. This is no longer the case. Options now include 1GB, 2GB, and 4GB. Additionally, memory transfer speeds should be faster as the Raspberry Pi 4 will utilize LPDDR4 instead of LPDDR2.
Networking will also be faster with Gigabit Ethernet instead of Ethernet over USB 2.0. And speaking of USB, instead of four USB 2 ports, there are now two USB 3 and two USB 2 ports. Power is also handled via a USB-C port instead of the micro-USB port we’ve seen in the past.
The rest of the specs are pretty similar to previous iterations of the Raspberry Pi. There’s a microSD card slot so that you can put the operating system and user data on a memory card as well as a 40-pin GPIO header that should be compatible with existing add-on boards. And, as always, the Raspberry Pi Foundation has kept all of its software backward-compatible meaning any projects created on a Raspberry Pi 4 will work on any older models too.
The Rasberry Pi 4 launches today. The base model still costs $35, but the 2GB RAM model costs $45 and the 4GB RAM model costs $55. Will you be picking any of these up? What projects will you be using them for? Let us know in the comments below!
