Raspberry Pi 4 Model B, the completely upgraded, re-engineered model of the Pi family. It has more powerful processor, faster networking, supports dual 4K output, and provides different choice of RAM.
Compared to the prior-generation Raspberry Pi 3 Model B+, Raspberry Pi 4B offers significantly increases in processor speed, multimedia performance, memory, and connectivity. For the end user, Raspberry Pi 4 Model B provides desktop performance comparable to entry-level x86 PC systems, which could let you enjoy smooth and high-quality experience! Raspberry Pi 4B includes a high-performance 64-bit quad-core processor, and features dual-display support at resolutions up to 4K via a pair of micro-HDMI ports, hardware video decode at up to 4Kp60, up to 4GB of RAM, dual-band 2.4/5.0 GHz wireless LAN, Bluetooth 5.0, Gigabit Ethernet, USB 3.0, and PoE capability (via a separate PoE HAT add-on).
