The microSD card slot is also twice as fast, offering a theoretical maximum of 50 MBps versus 25 MBps on the 3B+.īecause the new SoC needs more power, the Raspberry Pi 4 B charges over USB Type-C instead of micro USB. The higher bus speed that enables USB 3 support also allows the on-board Ethernet port to support true Gigabit connections (125 MBps) where the last-gen models had a theoretical maximum of just 41 MBps. The most important new features are the faster processor, a 1.5-GHz Broadcom CPU and GPU, more and faster RAM, the addition of USB 3 ports, dual micro HDMI ports (instead of a single HDMI connection) and support for 4K output. If all you’re doing with your Pi is running a security camera or playing old arcade games, you might be able to stick with what you have, but you’ll definitely want a Pi 4 for future projects. The newer platform has a number of distinctive advantages, including speeds that are two to four times faster, support for USB 3 and true Gigabit Ethernet and dual video output with resolutions up to 4K. However, if you’re looking for an all-around, general purpose Raspberry Pi, there’s no doubt that it’s the Raspberry Pi 4, which goes by the official model name of Raspberry Pi 4 B (there’s no 4 A, so the B is superfluous).īut let’s say you already own a Raspberry Pi 3 or an earlier model and are wondering if you should also get a Raspberry Pi 4. But choosing which Raspberry Pi to buy is an open question because there are reasons you might want to get a different model, such as the $5 Raspberry Pi Zero.
