Two of the four USB ports have been upgraded to USB 3.0, and the power supply now uses USB-C which allows for an increase in current to 3A over the old 2.5A microUSB port. The Pi 4 also sports a 500 MHz VideoCore VI GPU and anywhere from 1 to 4GB of RAM, depending on the board you purchase.ĭanielle Abraham + 1 moreI/O sees a noticeable improvement as well, with Gigabit Ethernet replacing the old 330 Megabit port on the 3 B+. But the Cortex-A72 architecture is actually much faster than the Cortex-A53, even at the same clock speed, so the Raspberry Pi Foundation says the Pi 4’s CPU should be about three times as fast as the previous model. The Pi 3 B+ ran a 1.4GHz Cortex-A53, which may seem like a negligible difference if you’re only looking at clock speed. Raspberry Pi 4 – Design and FeaturesThe Model B brings a noticeable spec bump from its predecessor, starting with its 1.5GHz quad-core 64-bit ARM Cortex-A72 CPU.
The latest Raspberry Pi 4 kicks the specs up yet another notch, and offering multiple versions with up to 4GB of RAM,but is it enough to work as a cheap little desktop PC? The Raspberry Pi Foundation lent us a board to find out. For $35, you get a tiny computer about the size of a deck of cards that you can use to make your own electronics projects, play video games, or teach yourself to code. The Raspberry Pi has been a fascinating device ever since the first version launched back in 2012.
