The Raspberry Pi 4 Model B has been launched, despite months of tricky misdirection implying that it wouldn't be on the market until 2020. The technical specifications include two micro HDMI ports, two USB3 ports, two USB2 ports, dual band Wi-fi, Bluetooth 5, Gigabit Ethernet, and either 1GB, 2GB, or 4GB of RAM. Power consumption is noticeably higher than similar earlier models and the power can be supplied over USBC.

From the spec sheet:

  • Broadcom BCM2711, Quad core Cortex-A72 (ARM v8) 64-bit SoC @ 1.5GHz
  • 1GB ($35), 2GB ($45), or 4GB LPDDR4-2400 SDRAM ($55)
  • 2.4 GHz and 5.0 GHz IEEE 802.11ac wireless, Bluetooth 5.0, BLE
  • Gigabit Ethernet
  • 2 USB 3.0 ports; 2 USB 2.0 ports.
  • Raspberry Pi standard 40 pin GPIO header (fully backwards compatible with previous boards)
  • 2 × micro-HDMI ports (up to 4kp60 supported)
  • 2-lane MIPI DSI display port
  • 2-lane MIPI CSI camera port
  • 4-pole stereo audio and composite video port
  • H.265 (4kp60 decode), H264 (1080p60 decode, 1080p30 encode)
  • OpenGL ES 3.0 graphics
  • Micro-SD card slot for loading operating system and data storage
  • 5V DC via USB-C connector (minimum 3A*)
  • 5V DC via GPIO header (minimum 3A*)
  • Power over Ethernet (PoE) enabled (requires separate PoE HAT)
  • Operating temperature: 0 – 50 degrees C ambient

takyon: Review at Tom's Hardware. Cons: "Key software doesn't work at launch, Poor high-res video playback". Cases for the previous Pi don't work due to the new micro-HDMI ports. Tom's measured nearly ten times better storage performance using one of the new USB 3.0 ports, and the gigabit Ethernet port can actually reach nearly 1 Gbps (943 Mbps vs. 237 Mbps for the previous model).

    They also mentioned that the USB and Ethernet have also moved 1mm outward. Not sure if it will make a difference to you.

    Of course, 1mm outward for the microbes it's a huge difference, like a petri dish football field, tehy are tiny!
