Raspberry Pi 4 is announced

The Raspberry Pi foundation has announced the newest version of its low-cost, miniature computer.
The Raspberry Pi 4 looks very similar to its predecessor, but the speed and performance is a step up from earlier models, and a few tweaks have been made to the form factor to accommodate new features:
  • The power connector has changed from USB micro-B to USB-C, which, according to the Raspberry Pi Foundation, “supports an extra 500mA of current, ensuring we have a full 1.2A for downstream USB devices, even under heavy CPU load”.
  • The former type-A HDMI connector has now been replaced with a pair of type-D HDMI connectors to accommodate the dual display output feature, which supports resolutions up to 4K. PCB routing has also been simplified with the movement of the Gigabit Ethernet magjack from the bottom right of the board to the top right.
  • The Ethernet controller on the main SoC is connected to an external Broadcom PHY over a dedicated RGMII link, providing full throughput. USB is provided via an external VLI controller, connected over a single PCI Express Gen 2 lane, and providing a total of 4Gbps of bandwidth, shared between the four ports.
  • All three connectors on the right-hand side of the board overhang the edge by an additional millimetre, with the aim of simplifying case design. In all other respects, the connector and mounting hole layout remains the same, ensuring compatibility with existing HATs and other accessories.
The Raspberry Pi Foundation has listed the following highlights for the Raspberry Pi 4:
A 1.5GHz quad-core 64-bit ARM Cortex-A72 CPU (~3× performance)
1GB, 2GB, or 4GB of LPDDR4 SDRAM
Full-throughput Gigabit Ethernet
Dual-band 802.11ac wireless networking
Bluetooth 5.0
Two USB 3.0 and two USB 2.0 ports
Dual monitor support, at resolutions up to 4K
VideoCore VI graphics, supporting OpenGL ES 3.x
4Kp60 hardware decode of HEVC video
Complete compatibility with earlier Raspberry Pi products
