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.
All other hardware is the same as before except the RAM variation in this new Launch.
What else has changed?
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.
Key Features and Specifications of Raspberry Pi 4 Moedl B with 8GB RAM:
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).
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. However; it should note 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!
