Grab A Slice Of LPDDR4, BCM2837 And USB-C Charging
Those are the biggest changes to the new Raspberry Pi 4, all four models are powered by a 1.5GHZ quad-core Cortex-A72 Broadcom BCM2711 with the difference being the amount of memory available; $35 gets you 1GB, $45 2GB and $55 a full 4GB of LPDDR4. These changes allow the connectivity options to be upgraded as well, with a pair of USB 3.0 ports as well as two USB 2.0 on the box, ethernet, audio and two mini HDMI ports. With the new hardware, that means you can attach a pair of 4K monitors to the Pi and expect them to work perfectly!
The gang over at Mythic Beasts put together an 18 Pi cluster in a few hours and it is doing a lot of the work hosting www.raspberrypi.org at the moment. The amount of traffic is a bit much to expect from them, as is handling the WordPress database but fourteen of them can handle all the PHP code execution, two serve up static files, and two handle Memcached optimization. If you are interested in picking one up but aren’t quite sure what to do with it, there are more than a few suggestions to be found here.
The new Raspberry Pi 4 was released quietly on Monday, but not before we had a chance to poke around with what is undoubtedly the biggest leap forward for the series since it began - for the first time, it's not just a maker board. It's a full-blown computer.
