Raspberry Pi 5 Model B – BCM2712 Quad-Core Cortex-A76 @ 2.4GHz | Up to 16GB LPDDR4X | PCIe 2.0 | Dual 4K HDMI

The Raspberry Pi 5 Model B is the most powerful single-board computer Raspberry Pi has ever built — delivering 2–3× the performance of Raspberry Pi 4 in real-world workloads. Powered by the new Broadcom BCM2712 quad-core Cortex-A76 processor at 2.4GHz, featuring a dedicated RP1 southbridge I/O chip and up to 16GB LPDDR4X-4267 RAM, it introduces the first-ever PCIe 2.0 interface on a Raspberry Pi for NVMe SSD expansion, a built-in real-time clock (RTC), and significantly improved USB, camera, and display performance. Whether you're deploying edge AI, building robotics systems, running a home server, or learning embedded Linux — the Raspberry Pi 5 is the definitive platform for serious makers and engineers.

Why the Raspberry Pi 5 Is a Major Leap Forward

The Raspberry Pi 5 isn't just a spec bump — it's a ground-up redesign. The new RP1 southbridge chip offloads all I/O (USB, camera, GPIO, Ethernet) from the main SoC, giving each subsystem dedicated bandwidth and eliminating the bottlenecks that limited the Pi 4. The result is a board that can run two 4K displays, stream from cameras, serve USB 3.0 devices, and process GPIO — all simultaneously, without performance compromise.

Technical Specifications

What's in the Box

• 1× Raspberry Pi 5 Model B (as per selected RAM variant)

Note: MicroSD card, power supply, case, and cooling are not included. The official Raspberry Pi 27W USB-C PD Power Supply is strongly recommended — a standard phone charger will reduce USB port power budget and may limit peripheral performance. Pi 4 cases and DSI/CSI cables are not compatible due to repositioned connectors; use Pi 5-specific enclosures and adapters.

Recommended Accessories

• Power Supply: Official Raspberry Pi 27W USB-C PD Supply (5.1V / 5A) — required for full performance and full USB port power
• Storage: MicroSD card (Class 10, U3, V30, A2 rated) — 64GB or larger recommended; or NVMe SSD via M.2 HAT+

Frequently Asked Questions

Which power supply do I need for the Raspberry Pi 5?

The official Raspberry Pi 27W USB-C PD Power Supply (5V / 5A) is strongly recommended. If a USB-C charger without Power Delivery negotiation is used, the Pi 5 enters a compatibility mode that limits each USB port to 600mA (versus 1.6A per port with the official PSU). For basic desktop use a 5V / 3A (15W) supply will work, but you may see under-voltage warnings under heavy peripheral loads.

Does the Raspberry Pi 5 need active cooling?

Yes, for sustained workloads. Without cooling, the Pi 5 idles around 65°C and starts throttling at 80°C. With the official active cooler or a quality fan, temperatures stay around 50–55°C under full load indefinitely. Passive cooling alone is generally not sufficient for AI inference, video encoding, or other CPU-intensive tasks.

Is the Raspberry Pi 5 backward compatible with Pi 4 accessories?

Partially. The 40-pin GPIO header maintains the same pinout for HATs, though some software changes may be needed. However, Pi 4 cases do not physically fit due to repositioned connectors and the new power button. The CSI and DSI connectors are now 22-pin / 0.5mm pitch (smaller than Pi 4's 15-pin), so existing camera and display ribbons need an adapter cable.

Can I use an NVMe SSD with the Raspberry Pi 5?

Yes. The Pi 5's PCIe 2.0 x1 FPC connector supports NVMe SSDs via the official M.2 HAT+ or compatible third-party adapters. NVMe storage is significantly faster than MicroSD and is recommended for OS boot, databases, and high-throughput applications. PCIe Gen 3 speeds are not officially certified and may be unstable.

How much faster is the Pi 5 compared to the Pi 4?

In real-world benchmarks: 2–3× faster CPU performance, ~3× faster web browsing, ~2× faster file compression, ~3× faster GPU performance, and 5–6× higher memory bandwidth. The Pi 5 also brings a completely re-engineered I/O stack via the RP1 chip, which alone eliminates many bandwidth bottlenecks that existed in Pi 4.

What is the RP1 chip and why does it matter?

The RP1 is a custom southbridge I/O controller designed by Raspberry Pi Ltd. In previous models, all I/O shared bandwidth through the main SoC's USB 3.0 hub. The RP1 gives USB, Ethernet, camera pipelines, and GPIO their own dedicated pathways — meaning you can stream from two cameras, serve USB 3.0 devices, and run GPIO peripherals simultaneously without any one subsystem starving the others.

What is the built-in real-time clock (RTC) used for?

The Pi 5 includes an integrated RTC backed by a 32kHz crystal oscillator. With a small coin-cell battery connected to the RTC header, the Pi can maintain accurate time even while powered off — useful for offline data loggers, remote cameras, and industrial sensors. The RTC also enables timed power-on wake-up, allowing the Pi to boot at a scheduled time without external intervention.

What operating systems are supported?

Raspberry Pi OS (Bookworm, 64-bit) is the primary and best-supported OS. Other options include Ubuntu Desktop and Server 24.04 LTS / 25.04, Armbian, DietPi, Kali Linux, and various community distributions. A 64-bit OS is strongly recommended to take full advantage of the Cortex-A76 architecture and available RAM above 4GB.

Which RAM variant should I choose?

4GB is the best choice for most users — ample for desktop use, robotics projects, and light AI workloads. 8GB is recommended for running multiple applications simultaneously, heavier AI inference, or compiling large software. 16GB suits memory-intensive server workloads, large language model inference, or running several containers simultaneously. The 2GB variant is suitable for dedicated, single-task appliances (Pi-hole, VPN, sensors).

Does the Pi 5 support Wi-Fi 6 or Ethernet PoE?

The Pi 5 uses dual-band 802.11ac (Wi-Fi 5), not Wi-Fi 6. Wi-Fi throughput is approximately 3× faster than Pi 4 due to an improved SDIO interface. Power over Ethernet (PoE+) is supported via a compatible PoE+ HAT (sold separately); it is not built in.

Can the Raspberry Pi 5 run AI and machine learning workloads?

Yes. The Pi 5 runs TensorFlow Lite, ONNX Runtime, and PyTorch (ARM builds) natively. For significantly accelerated inference, the Raspberry Pi AI Kit adds a Hailo-8L NPU (13 TOPS) via the PCIe interface, enabling real-time object detection at 30+ FPS. Google Coral USB Accelerator is also compatible via USB 3.0.

Note: MicroSD card, power supply, case, cooling, and display cables are not included. The official 27W USB-C PD Power Supply is strongly recommended for full performance and maximum USB port power.
