The Raspberry Pi Foundation has delivered its next single-board computer a year early. The Raspberry Pi 4 Model B comes with a quad-core CPU, up to 4 GB of LPDDR4 RAM, Gigabit Ethernet dual 4K HDMI and USB Type-C. It should deliver 3x the performance of its predecessor while remaining backwards-compatible with older boards. Better still, the Raspberry Pi 4 Model B costs just US$35 and is available to order worldwide now.
