Key Features:

Faster processing:

  • With one of latest Broadcom 2711, Quad-Core Cortex A72 (ARM V8-A)  64-bit SoC Clocked at  1.5GHz  processor improved power consumptions and thermals on the Pi 4+Bmeans that the CPU on the BCM2837 SoC can now run at 1.5GHz, a 20% increase on the previous Pi 3 model (which ran at 1.2GHz).
  • Hardware upgrade on Pi4 developed for more faster performance e with all new 1GB/2GB and 4GB LPDDR4 SDRAM variants.
  • Video performance on Pi 4 B is also upgraded with dual-display support at resolutions up to 4K via a pair of micro-HDMI ports, hardware video decode at up to 4Kp60 which supports H 265 Decode (4Kp60), H.264, and MPEG-4 decode (1080p60).

Faster wireless:

  • A significant change on the Pi 4 B compared to the previous Pi 3 models is the inclusion of a new faster, dual-band wireless chip with 802.11 b/g/n/ac wireless LAN.
  • The dual-band 2.4GHz and 5GHz wireless LAN enables faster networking with less interference and the new PCB antenna technology allow better reception.
  • Latest 5.0 Bluetooth allows you to use a wireless keyboard/trackpad with more range than before without extra dongles, keeping things nice and tidy.

Enhanced Ethernet Connectivity:

  • The Pi 4 B has significantly faster-wired networking with USB 3.0 technology, thanks to an upgraded USB/LAN chip, and you should see speeds that are 10x faster than on previous models of the Pi.
  • The GPIO header remains the same, with 40 pins, fully backward-compatible with previous boards as on the previous three models of Pi. However, it should be noted that the new PoE header pins may contact components on the underside of some HATs, like Rainbow HAT. Some standoffs will prevent any mischief from occurring though.
