Two USB 3.0 ports, centre, offer high-speed connectivity for external devices including storage and accelerator hardware. The Ethernet port, relocated to the top-right of the board, now offers full-speed network connectivity with no bottlenecks. The two micro-HDMI connectors enable Raspberry Pi 4 to drive two 4K displays at up to 4Kp30, or a single display at up to 4Kp60 The new BCM2711B0 system-on-chip offers an impressive performance boost over its predecessors. Ports: 2 × micro-HDMI 2.0, 3.5 mm analogue audio-video jack, 2 × USB 2.0, 2 × USB 3.0, Gigabit Ethernet, Camera Serial Interface (CSI), Display Serial Interface (DSI).Bluetooth: Bluetooth 5.0, Bluetooth Low Energy (BLE).Networking: 2.4 GHz and 5 GHz 802.11b/g/n/ac wireless LAN.Gone is the single-lane USB bottleneck which hampered performance on older models, and Raspberry Pi 4 shines in benchmarks as a result. The brand-new BCM2711B0 system-on-chip has more powerful processing cores, the first upgrade to the graphics processor in the history of the project, and vastly improved bandwidth for both memory and external hardware. It's not hard to see where this benchmark boost comes from. Our Raspberry Pi 4 benchmark tests show a huge increase in performance over previous models. Raspberry Pi 4 improves on its predecessor, with improved specifications across the board.
