Raspberry Pi 5 8GB Review: The Pocket-Sized Powerhouse Redefined

I remember a few years ago, wrestling with a home automation project. My goal was simple: create a central hub to manage lights, sensors, and a media server. I started with an older single-board computer, and while it was a marvel of miniaturisation, it quickly became a bottleneck. The web interface for my smart home software was sluggish, Plex would buffer endlessly if anyone else used the network, and compiling even a small piece of code felt like it took an eternity. It was a classic case of a brilliant idea being held back by a lack of raw processing power. This frustration is a common story in the maker community—we dream big, but the hardware can’t always keep up. The search for a device that is small, power-efficient, and yet powerful enough to run modern applications without compromise has been the holy grail for hobbyists and developers alike.

What to Consider Before Buying a Single-Board Computer

A single-board computer (SBC) is more than just an item; it’s a key solution for a universe of creative projects. Unlike a traditional motherboard which is just one component of a larger system, an SBC like the Raspberry Pi 5 8GB is a complete, self-contained computer on a single circuit board. Its main benefits are its incredibly small footprint, low power consumption, and affordability, making it the perfect brain for everything from robotics and home automation hubs to mini web servers and retro gaming consoles. It empowers you to build custom solutions that would be impractical or prohibitively expensive with conventional computer hardware. The true value lies in its versatility and the massive community supporting it, providing endless tutorials and open-source software.

The ideal customer for this type of product is someone with a spark of curiosity and a project in mind—a tinkerer, a student learning to code, a developer prototyping an IoT device, or a home automation enthusiast looking to build a powerful and efficient server. It’s for people who are comfortable with a command line and enjoy the process of building and configuring their own systems. However, it might not be suitable for those who need a high-performance gaming PC or a simple, out-of-the-box desktop computer that requires zero setup. For those users, a pre-built Mini PC or a standard desktop computer would be a more appropriate, albeit larger and more power-hungry, alternative.

Before investing, consider these crucial points in detail:

• Dimensions & Space: The credit-card-sized form factor is a defining feature of the Raspberry Pi series. Before buying, consider the enclosure you plan to use and the physical space your project allows. While the board itself is tiny (8.5 x 5.6 cm), accessories like cooling fans, HATs (Hardware Attached on Top), and cabling will add to the final dimensions.
• Capacity/Performance: The jump to a 2.4GHz quad-core 64-bit Arm Cortex-A76 CPU in the Raspberry Pi 5 8GB is a monumental leap. This, combined with 8GB of RAM, determines how smoothly it can run a desktop OS, handle multiple applications simultaneously, or manage demanding server tasks. For heavy multitasking or applications like containerisation with Docker, the 8GB model is the clear choice over its smaller-RAM siblings.
• I/O & Connectivity: Evaluate your project’s need for ports. The Raspberry Pi 5 8GB offers two USB 3.0 ports for fast data transfer, two USB 2.0 ports for peripherals, Gigabit Ethernet for stable networking, and now, a PCIe 2.0 interface. This PCIe slot is a game-changer, allowing for the connection of high-speed devices like NVMe SSDs, which dramatically outperform traditional microSD cards.
• Power & Thermal Management: With great power comes greater power consumption. Unlike its predecessors, the Raspberry Pi 5 8GB requires a more robust power supply, specifically a 5V/5A (27W) USB-C adapter, to perform reliably under load. Furthermore, due to the more powerful CPU, active cooling is no longer optional but a near necessity to prevent thermal throttling and ensure sustained performance.

Keeping these factors in mind, the Raspberry Pi 5 8GB stands out in several areas, particularly in its raw performance and the addition of PCIe. You can explore its detailed specifications and features here.

While the Raspberry Pi 5 8GB is an excellent choice, it’s always wise to see how it stacks up against the competition. For a broader look at all the top models, we highly recommend checking out our complete, in-depth guide:

Unboxing the Raspberry Pi 5 8GB: A Familiar Form with a Fiery Heart

Upon receiving the Raspberry Pi 5 8GB, the first thing we noticed was the packaging. It arrives in the iconic, minimalist cardboard box, which is part of the brand’s low-cost ethos. However, we must concur with the feedback from several users who expressed concern about the lack of protective padding. Our unit arrived intact, but the flimsy nature of the box means its survival is largely dependent on the care taken during shipping. Inside, the board is presented without an anti-static bag, another cost-saving measure that feels like a slight oversight for such a sophisticated piece of electronics.

Picking up the board itself, the build quality is excellent, as we’ve come to expect from the Raspberry Pi Foundation. The layout is familiar yet distinctly new. The Ethernet and USB ports have been swapped, a practical change that many will appreciate. The most welcome new physical features are the dedicated power button—a long-requested addition that eliminates the old “pull the plug” method of shutting down—and the small fan connector, a clear acknowledgement of the board’s new thermal needs. The credit-card-sized footprint remains, ensuring backward compatibility with a vast ecosystem of cases and accessories, though new port cutouts will be required. It immediately feels like a more mature, refined product ready for serious work.

Putting the Raspberry Pi 5 8GB Through Its Paces: A Performance Deep Dive

For years, the Raspberry Pi has been the undisputed king of single-board computers, but it always came with a caveat: it was great *for its size and price*. With the Raspberry Pi 5 8GB, that caveat is starting to fade. This isn’t just an incremental update; it’s a foundational leap that redefines what we can expect from a computer that fits in a mint tin. We spent weeks pushing this board to its limits, using it as a desktop, a server, and a development platform, to see if the hype was real. The answer is a resounding yes.

The New Heart of the Pi: Cortex-A76 CPU and 8GB RAM

The single biggest upgrade is the Broadcom BCM2712 SoC, featuring a quad-core 2.4GHz Arm Cortex-A76 CPU. In our testing, the difference was not subtle; it was transformative. We set up Raspberry Pi OS (Bookworm) and used it as a daily desktop machine. On the Pi 4, opening more than a few browser tabs while a YouTube video played in the background would result in noticeable stuttering. On the Raspberry Pi 5 8GB, this task was handled with ease. We could have a dozen tabs open in Chromium, run a code editor like VS Code, and stream 1080p video without the system breaking a sweat. This is the first time a Raspberry Pi has felt like a genuinely viable, albeit basic, desktop computer for everyday tasks. This experience is echoed by users, with one describing the performance as a “Quantensprung” (quantum leap) and another noting that Home Assistant runs “butterweich” (buttery smooth). The 8GB of LPDDR4X RAM is the perfect complement to this new CPU. It provides the headroom needed for demanding applications and heavy multitasking, making it the ideal choice for running multiple services in Docker containers—a popular use case for home server enthusiasts running applications like Home Assistant, Pi-hole, and a NAS simultaneously.

A Game-Changer for Storage and Peripherals: The PCIe Connection

Perhaps the most exciting new feature for power users is the single-lane PCIe 2.0 interface. For years, the Achilles’ heel of the Raspberry Pi has been storage speed, limited by the performance of the microSD card slot. While the slot on the Pi 5 is twice as fast, it’s the PCIe connection that unlocks true server-grade performance. We paired our Raspberry Pi 5 8GB with an NVMe HAT and a 256GB NVMe SSD. The results were astounding. Boot times were slashed from nearly a minute to just a few seconds. Applications launched instantly, and file transfer operations were an order of magnitude faster. This completely changes the calculus for what’s possible. Running a database, hosting a website with dynamic content, or even operating a 24/7 game server—as one user successfully did with a modded Minecraft server—is now entirely feasible. The PCIe bus removes the I/O bottleneck that previously relegated the Pi to lighter-duty tasks. For anyone looking to build a reliable and fast mini-server, leveraging this feature is a must, and it firmly places the Raspberry Pi 5 8GB in a class of its own within the SBC market.

Connectivity and I/O: More Than Just a Speed Bump

The Raspberry Pi Foundation didn’t just focus on the CPU; they overhauled the entire I/O subsystem. The two USB 3.0 ports can now sustain their full 5Gbps transfer speeds simultaneously, a limitation on the previous model. In our tests, we could read from a high-speed SSD on one port while writing to another external drive on the second port with no degradation in performance. This is a significant improvement for anyone planning to use the Pi as a Network Attached Storage (NAS) device. The Gigabit Ethernet port is also faster and more reliable. On top of that, the dual-band 802.11ac Wi-Fi and Bluetooth 5.0 provide robust wireless connectivity. Another major upgrade is the graphics capability. The VideoCore VII GPU can now drive two 4K displays at 60Hz simultaneously, complete with HDR support. While it won’t be running AAA games, this makes the Raspberry Pi 5 8GB an incredibly capable device for digital signage, multi-monitor productivity setups, or a sophisticated home theatre PC.

Power, Thermals, and the Real-World Cost of Performance

This massive performance boost doesn’t come for free. The Raspberry Pi 5 8GB is a thirstier board, demanding a 5V/5A (27W) power supply to operate at its peak. During our stress tests, we found that using an older 3A supply led to low-voltage warnings and instability. The official 27W USB-C Power Supply is strongly recommended. The other critical consideration is heat. The Cortex-A76 cores run significantly hotter than their predecessors. We ran a CPU stress test without any cooling, and the processor began to thermal throttle within a minute. Attaching the official Active Cooler, a small fan/heatsink combo, completely solved the problem, allowing the CPU to maintain its full 2.4GHz clock speed indefinitely. Our conclusion, shared by many experienced users, is that an active cooling solution is not an optional accessory; it is a mandatory component to unlock the full performance of the Raspberry Pi 5 8GB. The convenience of the new on-board power button cannot be overstated—it’s a small addition that makes using the Pi as a desktop or server so much more civilized.

What Other Users Are Saying

Our positive experience is largely mirrored by the wider community. There is a palpable sense of excitement around the performance jump. One user, who uses the Raspberry Pi 5 8GB for a Homebridge server, called it a “latest power house,” praising its build and easy setup. Another reported successfully running a heavily modded Curseforge Minecraft server for friends, something that would have been unthinkable on older models. The versatility is a constant theme, with users deploying it for everything from smart home control with Home Assistant to network-wide ad-blocking with Pi-hole and acting as a VPN server.

However, the feedback isn’t universally glowing, and the criticisms align with our own findings. A recurring complaint, as mentioned, is the minimal shipping packaging, which one user described as a “flimsy cardboard box” inside a paper envelope, leading to concerns about the device’s durability during transit. The other major point of friction is the increased power and thermal requirements. One German user noted that while the performance is a huge improvement, “Mit der Leistungssteigerung kommt leider auch ein signifikanter Anstieg der Abwärme” (With the performance increase, unfortunately, also comes a significant increase in waste heat), making active cooling a necessity and adding to the total cost of ownership.
