In honor of
Recall that the Raspberry Pi 4 board is equipped with a BCM2711 SoC and includes four 64-bit ARMv8 Cortex-A72 cores running at 1.5GHz and a VideoCore VI graphics accelerator that supports OpenGL ES 3.0 and is capable of decoding H.265 video with quality 4Kp60 (or 4Kp30 on two monitors). The board is equipped with LPDDR4 memory, PCI Express controller, Gigabit Ethernet, two USB 3.0 ports (plus two USB 2.0 ports), two Micro HDMI (4K) ports, 40-pin GPIO, DSI (touch screen connection), CSI (camera connection) and 802.11ac wireless chip, 2.4GHz and 5GHz bands, and Bluetooth 5.0. Power can be supplied via a USB-C port (formerly USB micro-B), via GPIO, or via an optional PoE HAT (Power over Ethernet) module. In performance tests, Raspberry Pi 4 outperforms Raspberry Pi 3B+ by 2-4 times, and Raspberry Pi 1 by 40 times.
