The Raspberry Pi 4 Model B with 4GB RAM is one of the most powerful additions to the popular Raspberry Pi family. It brings major improvements in processing power, multimedia capabilities, memory performance, and connectivity compared to the previous-generation Raspberry Pi 3 Model B+—all while maintaining similar power consumption and full backward compatibility. With its enhanced architecture, the Raspberry Pi 4 Model B delivers desktop-class performance comparable to entry-level x86 PCs.
Powered by the latest quad-core 64-bit Broadcom BCM2711 Cortex-A72 processor clocked at 1.5GHz, the Pi 4 Model B offers up to 20% lower power consumption and as much as 90% better performance than earlier versions. The upgrade includes multiple RAM options (1GB / 2GB / 4GB LPDDR4), improved wireless connectivity with dual-band 2.4GHz/5GHz 802.11 b/g/n/ac Wi-Fi, and support for Power over Ethernet (PoE) via an additional PoE HAT.
Enhanced Multimedia Performance
Enjoy true 4K entertainment thanks to the upgraded VideoCore VI graphics processor. The Raspberry Pi 4 supports dual 4K displays via two micro-HDMI ports and can handle H.265 (4Kp60), H.264, and MPEG-4 (1080p60) hardware decoding—offering smoother, sharper video playback than ever before.
Improved Connectivity
Bluetooth 5.0 delivers faster data transfer, extended range, and better stability for wireless peripherals such as keyboards, mice, and IoT accessories. Another major improvement is the switch to a USB Type-C power port, allowing the Pi to draw up to 3A of current. This ensures sufficient power for the board and any connected peripherals.
