Raspberry Pi 4 Model B with 4GB RAM is the latest product in the popular Raspberry Pi range of computers. It offers ground-breaking increases in processor speed, multimedia performance, memory, and connectivity compared to the prior-generation Raspberry Pi 3 Model B+ while retaining backward compatibility and similar power consumption. For the end-user, Raspberry Pi 4 Model B provides desktop performance comparable to entry-level x86 PC systems.
Pi 4 B is upgraded with the 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 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.
