The fourth generation of the Raspberry Pi has been announced. Each generation of the Raspberry Pi is primarily identified by its specifications. (Not including the Raspberry Pi Compute module because it generally is not used by hobbyist). With the Raspberry Pi 4, this isn’t the case. There are three variations available. The new Raspberry Pi 4 comes with a 1.5 GHz ARM Cortex-A72 quad-core processor. With that processor the Raspberry Pi 4 can decode 4K video at 60 FPS or two 4K videos at 30 FPS. The amount of RAM available to the unit depends on the version. The smallest amount of RAM, 1 gig, is available for $35 USD. The next size, 2 gigs, can be purchased for $45 USD. The largest unit, 4 gigs, is $55 USD.
At first glance, the unit will be recognized as a Raspberry PI but a closer look at the ports will show some immediate differences. The Pi has converted from a micro-USB port to USB-C. The full sized HDMI port is gone and has been replaced with two micro-HDMI ports. The unit can drive two displays at once. A couple of the 4 USB ports have been upgraded to USB 3 while the other two are still USB 2. The wireless capabilities are upgraded to use USB 5.0 and dual-band 802.11ac Wi-Fi.
The unit is available for purchase from Raspberry Pi’s site now. A new case for the Pi 4 and a USB-C power supply of appropriate wattage are both available through the site as well.
