Raspberry Pi 4 Model B was launched in June 2019 with many significant upgrades that increase the performance of this mini computer up to 3x times.

Raspberry Pi 4 Model B specifications:

Broadcom BCM2711, Quad core Cortex-A72 (ARM v8) 64-bit SoC @ 1.5GHz There are 3 RAM options: 2GB, 4GB or 8GB LPDDR4-2400 SDRAM Wifi standard 2.4 GHz and 5.0 GHz IEEE 802.11ac. Bluetooth 5.0, BLE Gigabit Ethernet port 2 USB 3.0 ports and 2 USB 2.0 ports 40-pin GPIO standard, compatible with previous versions Support 2 Micro HDMI display output ports with resolution up to 4K MIPI DSI port MIPI CSI port 4-pin AV port H.265 (4kp60 decode), H264 (1080p60 decode, 1080p30 encode) OpenGL ES 3.0 graphics Micro-SD slot for operating system and storage DC 5V – 3A DC power supply USB-C standard 5V DC via GPIO header (minimum 3A*) Power over Ethernet (PoE) support (requires PoE HAT) Raspberry Pi 4 has the same small appearance as previous versions, but the board structure has completely changed. Therefore, you cannot use the case of previous versions for this version 4. Besides, the company also announced that you must use a 5V - 3A or higher power source for the Raspberry Pi 4 board.
