Introduction
Here comes the 4th generation Raspberry Pi model B of popular Raspberry Pi family! Compared to the prior-generation Raspberry Pi 3 Model B+, 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).
Silent, energy-efficient
The fanless, energy-efficient Raspberry Pi runs silently and uses far less power than other computers.
Fast networking
Raspberry Pi 4 comes with Gigabit Ethernet, along with onboard wireless networking and Bluetooth.
USB 3
Your new Raspberry Pi 4 has upgraded USB capacity: along with two USB 2 ports you'll find two USB 3 ports, which can transfer data up to ten times faster.
Your choice of RAM
Your new Raspberry Pi 4 has upgraded USB capacity: along with two USB 2 ports you'll find two USB 3 ports, which can transfer data up to ten times faster. We're making different variants of the Raspberry Pi 4 available, depending on how much RAM you need - 1GB, 2GB or 4GB.
