The Raspberry Pi Foundation has released a new version of its flagship model, the Raspberry Pi 4 Model B with 8 GB Ram. In addition to the models that come with 2GB and 4GB of RAM, there’s a new 8GB RAM model.

As always, you get a single-board computer that is the size of a deck of cards. It has an ARM-based CPU, many ports, Wi-Fi, Bluetooth and a big community of computer enthusiasts. You’ll be able to run applications that require more RAM, whether you use the Raspberry Pi to run a server or as a desktop computer. To supply the slightly higher peak currents required by the new memory package, they have shuffled the power supply components on the board, removing a switch-mode power supply from the right-hand side of the board next to the USB 2.0 sockets and adding a new switcher next to the USB-C power connector. While this was a necessary change for this upgrade.

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 consumption; and thermals on the Pi 4+B means that the CPU on the BCM2837 SoC can now run at 1.5 GHz; a 20% increase on the previous Pi 3 model (which ran at 1.2GHz).
  • Video performance on Pi 4 B is 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 backwards-compatible with previous boards as on the previous three models of Pi.
