Raspberry Pi 5: What's new and why it matters

What's new in Raspberry Pi 5

The Raspberry Pi 5 represents the biggest generational leap in Raspberry Pi history. Here are the key upgrades:

• Faster processor: 2.4GHz quad-core Arm Cortex-A76 CPU (up from 1.8GHz Cortex-A72 in Pi 4)
• Improved graphics: VideoCore VII GPU with OpenGL ES 3.1 and Vulkan 1.3 support
• More RAM options: 2GB, 4GB, 8GB, or 16GB LPDDR4X-4267 memory
• Faster storage: High-speed microSD card interface with SDR104 mode support
• PCIe expansion: PCIe 2.0 x1 interface for adding NVMe SSDs or other peripherals (adapter required)
• Dual 4K displays: Two micro-HDMI ports supporting dual 4K@60fps monitors with HDR
• USB 3.0: Two USB 3.0 ports (5Gbps) and two USB 2.0 ports
• Gigabit Ethernet with PoE+ support: Wired networking with Power over Ethernet capability (PoE+ HAT required)
• Real-time clock: On-board battery-backed RTC for keeping time when powered off
• Power button: Physical power button for safe shutdown without pulling the plug
• Fan connector: Four-pin PWM fan header for temperature-controlled active cooling

Performance improvements

The Raspberry Pi 5 delivers roughly 2–3× the CPU performance of the Raspberry Pi 4. This translates to faster boot times, snappier desktop responsiveness, quicker code compilation, and better performance in demanding applications.

What this means in practice

• Desktop use: Smooth multitasking, faster web browsing, and responsive application switching
• Programming: Faster build times when compiling code, reduced wait times in development workflows
• Media: Better video playback, hardware-accelerated 4K HEVC decoding, improved retro gaming emulation
• Servers and automation: Handle more simultaneous connections, process data faster, run multiple services smoothly
• AI and edge computing: Run inference models more quickly, enabling practical on-device machine learning

The performance increase is most noticeable under sustained load. For lightweight tasks, both Pi 4 and Pi 5 feel fast; but for intensive work, Pi 5 pulls ahead significantly.

Connectivity and I/O

USB 3.0 and faster storage

With USB 3.0 ports and a faster microSD interface, the Pi 5 can read and write data much more quickly than previous models. This makes a noticeable difference when booting from USB or running databases and file servers.

PCIe expansion

The Pi 5 includes a PCIe 2.0 x1 interface, allowing you to connect NVMe SSDs or other PCIe peripherals via an adapter. An SSD dramatically improves boot times and application responsiveness compared to microSD cards.

Dual displays

Two micro-HDMI ports support dual 4K displays at 60fps, making the Pi 5 a viable multi-monitor workstation for productivity, development, or digital signage.

Real-time clock

The on-board RTC maintains the correct time even when the Pi is powered off (with a coin cell battery installed). This is useful for servers, data loggers, and projects that need accurate timestamps.

How much RAM do you need?

The Raspberry Pi 5 is available with four memory options. Here's how to choose:

2GB — Budget-friendly basics

Good for simple projects, basic programming, and educational setups where cost is a priority. May struggle with heavy multitasking or memory-intensive applications.

4GB — General use

Ideal for desktop computing, coding, media centers, and retro gaming. Handles most tasks comfortably without breaking the budget. A safe choice for general-purpose use.

8GB — Advanced applications

Best for Docker containers, robotics, AI/machine learning, and development environments. Recommended if you plan to run multiple services simultaneously or work with larger datasets.

16GB — High-performance workloads

Designed for machine vision, data processing, running multiple virtual machines, or professional development work. Overkill for casual use, but invaluable for demanding projects.

If you're unsure, start with 4GB or 8GB. These options cover the majority of use cases and provide room to grow into more complex projects.

When to choose Raspberry Pi 5

The Raspberry Pi 5 is the best choice if you:

• Want the fastest, most capable Raspberry Pi available
• Plan to use it as a desktop replacement or primary development machine
• Need performance for demanding applications like AI, emulation, or video encoding
• Want future-proofing—more headroom for projects that grow in complexity
• Need PCIe expansion for NVMe storage or other peripherals

When Pi 4 or Zero might be better

The Pi 4 remains a solid, proven option for everyday coding, home automation, and familiar DIY projects. It's cheaper and widely supported.

The Pi Zero 2 W is ideal for compact, low-power builds where size matters more than raw performance.

But for most new projects—especially if you want room to grow—the Pi 5 is worth the investment. Its performance improvements make it feel significantly faster in daily use.
