 Featuring a 64-bit quad-core Arm Cortex-A76 processor running at 2.4GHz, Raspberry Pi 5 delivers a ×2 to ×3 increase in CPU performance relative to Raspberry Pi 4. Alongside a substantial uplift in graphics performance from an 800MHz VideoCore VII GPU; dual 4Kp60 display output over HDMI; and state-of-the-art camera support from a rearchitected Raspberry Pi Image Signal Processor, it provides a smooth desktop experience for consumers, and opens the door to new applications for industrial customers.

 If you are running the Raspberry Pi Desktop you can initiate a clean shutdown by briefly pressing the power button located on the left-hand side of the board, and then releasing it. This will cause a Desktop menu to appear asking whether you want to Shutdown, Reboot, or Logout. You can select whether you want to shutdown or reboot, or alternatively pressing the power button briefly for a second time will initiate a clean shutdown.

 The CSI and DSI ports found on previous models of Rasbpberry Pi have been combined into two dual-purpose CSI/DSI (MIPI) ports. To fit onto the board these now use a denser connector pinout, previously only found on Raspberry Pi Zero and the CM4IO board. You can connect two displays, two cameras, or one camera and one display to these ports.

 The Ethernet jack on Raspberry Pi 5 is PoE+ capable, supporting the IEEE 802.3at-2009 PoE standard. The Raspberry Pi 5 has a 4-pin Power-over-Ethernet (PoE) header block, located between the Ethernet jack and the two MIPI connectors.

 The Raspberry Pi PoE+ HAT for Raspberry Pi 5 is an add-on board for Raspberry Pi 5 computers which connects to the PoE header. It is used to power your Raspberry Pi via an Ethernet cable, provided that power-sourcing equipment is installed on the Ethernet network.

 While USB-PD capable phone chargers advertise greater than 15W of power, virtually all of them achieve this by increasing the voltage instead of providing more current at +5V. If you are using a power supply that cannot provide 5A at +5V on first boot you will be warned by the operating system that the current draw to peripherals will be restricted to 600mA.

 For users who wish to drive high-power peripherals like hard drives and SSDs, while retaining margin for peak workloads, a USB-PD enabled power supply capable of supplying a 5A at +5V (25W) should be used. If the Raspberry Pi 5 firmware detects such a supply, it increases the USB current limit for peripherals to 1.6A, providing 5W of extra power for downstream USB devices, and 5W of extra onboard power budget.

 The Raspberry Pi 5 has a dedicated debug UART connector. It has a maximum baud rate of 921,600bps, which can be configured with an EEPROM parameter. It is always active and enabled, and provides direct access to early boot and firmware information; as well as a Linux console after boot.
