The Raspberry Pi 4 Model B is the newest Raspberry Pi computer made, and the Pi Foundation knows you can always make a good thing better! And what could make the Pi 4 better than the 3 How about a faster processor, USB 3.0 ports, and updated Gigabit Ethernet chip with PoE capability Good guess - that's exactly what they did!

The Raspberry Pi 4 is the latest product in the Raspberry Pi range, boasting an updated 64-bit quad core processor running at 1.4GHz with built-in metal heatsink, USB 3 ports, dual-band 2.4GHz and 5GHz wireless LAN, faster (300 mbps) Ethernet, and PoE capability via a separate PoE HAT.

This version comes with 2GB of RAM, Pi 4 B is upgraded with Latest High-Performance Quad-Core 64-bit Broadcom 2711, Cortex A72  processor clocked at 1.5GHz speed. Which is designed to use 20% less power or offer 90% greater performance than its old version. Hardware upgrade on Pi4 developed for more faster performance not only the loading time with all new 1GB/2GB and 4GB LPDDR4 SDRAM variants but also in connectivity with Dual-band 2.4GHz and 5GHz, 802.11 b/g/n/ac wireless LAN and PoE capability via a separate PoE HAT. Addition to it USB 3.0, improve the transfer speed by 10x than USB 2.0 to provide you significantly faster true Gigabit internet experience.
