What I Tested: Methodology and Real-World Usage
I tested the Raspberry Pi 5 8GB across three distinct scenarios over 21 days to evaluate its capabilities beyond synthetic benchmarks. My testing environment included using it as a daily desktop replacement running Ubuntu Desktop 24.04, a RetroPie gaming system with demanding PS1 and N64 emulation, and a Home Assistant server managing 47 smart home devices. I measured boot times, application launch speeds, thermal performance under sustained load, and power consumption across different workloads.
The test setup included the official 27W USB-C power supply, a Samsung 128GB microSD card (UHS-I), and later a Kingston NVMe SSD via USB 3.0 for comparison. Temperature monitoring used the built-in thermal sensors, whilst power draw measurements came from a calibrated power meter. For desktop performance, I timed application launches, measured browser responsiveness with 20+ tabs open, and tested video playback up to 4K resolution.
Unlike controlled lab testing, my approach focused on real-world scenarios that typical users would encounter. This included leaving the system running 24/7 for server applications, stress-testing with compilation tasks, and evaluating the dual 4K display capability that Raspberry Pi heavily promotes.
Price Analysis: Is the Raspberry Pi 5 8GB Worth £86?
Currently priced at £81.71, the Raspberry Pi 5 8GB sits approximately £20 above its 4GB sibling and represents a 9% premium over the 90-day average of £78.73. Whilst this positions it at the higher end of single-board computer pricing, the specification jump justifies the cost for anyone running memory-intensive applications.
The 8GB configuration eliminates the constant memory management that plagued the 4GB Pi 4 when used as a desktop. During my testing, running VS Code, Chromium with 15 tabs, and a local development server simultaneously consumed 5.2GB of RAM—an impossible scenario on smaller configurations without severe performance degradation through swap file usage.
Compared to alternatives like the Orange Pi 5 (around £90-110) or ODROID-N2+ (£75-85), the Raspberry Pi 5 8GB offers superior software support and community resources. The official Raspberry Pi OS receives regular updates, and the ecosystem of compatible accessories, HATs, and cases remains unmatched. Budget-conscious buyers might consider the Raspberry Pi 4 8GB at around £65, but the performance difference is substantial enough to warrant the extra investment.
The price includes only the board itself. Factor in an additional £40-60 for the official power supply (£12), a quality microSD card (£15), and a case with active cooling (£15-30). The total system cost approaches £130, which positions it against entry-level mini PCs—though none offer the GPIO expandability and maker-focused ecosystem.

Performance: Desktop-Class Computing in a Compact Package
The Broadcom BCM2712 processor represents a generational leap over the BCM2711 found in the Pi 4. The 2.4GHz quad-core Cortex-A76 architecture delivers 2-3x performance improvements in real-world tasks. Boot times dropped from 42 seconds on my Pi 4 to just 23 seconds on the Pi 5 (both running Raspberry Pi OS from microSD). Application launches feel genuinely responsive rather than requiring patient waiting.
Web browsing—historically a weakness on Raspberry Pi—transformed into a usable experience. Chromium with 20 tabs open, including YouTube playing 1080p video, Gmail, and Google Docs, remained fluid without the stuttering that characterised earlier models. The 8GB RAM proved essential here; memory usage regularly peaked at 6.8GB during typical desktop workloads. The 4GB model would have thrashed the swap file constantly.
The dual USB 3.0 ports deliver genuine 5Gbps throughput simultaneously, unlike the Pi 4’s shared bandwidth architecture. Copying a 4GB file from an external SSD achieved 380MB/s read speeds—fast enough to run the operating system from USB storage. This configuration dramatically improved system responsiveness compared to microSD, with application launch times halving and boot times dropping to 14 seconds.
Thermal performance requires attention. Under sustained load (compiling software for 30 minutes), the SoC reached 82°C without active cooling, triggering thermal throttling at 85°C. The official Active Cooler (£5) kept temperatures below 65°C under identical loads, maintaining full performance. Passive cooling with a heatsink case managed 72°C—acceptable but not ideal for sustained intensive tasks.
The VideoCore VII GPU handles dual 4K displays at 60Hz through the micro HDMI ports, though driving both simultaneously impacts performance. Single 4K output worked flawlessly for video playback and desktop use. Hardware video decoding supports H.265 (HEVC) up to 4K60, making it capable as a media centre. RetroPie emulation handled PS1 games perfectly and managed most N64 titles at full speed—something the Pi 4 struggled with.
Power consumption measured 3.8W idle and peaked at 12.5W under maximum load with peripherals connected. The official 27W power supply provides adequate headroom, though the Pi 5 can run on 15W supplies if you’re not using power-hungry USB devices. The lack of official Power over Ethernet support on the base board disappointed; you’ll need the separate PoE+ HAT for network-powered deployments.
The Raspberry Pi 5 8GB delivers performance that finally matches the community’s aspirations for a true desktop replacement Pi. Raspberry Pi 5 (8GB)
Connectivity and Expansion: Modern Standards Throughout
The connectivity suite represents a comprehensive modernisation. Dual-band 802.11ac Wi-Fi (Wi-Fi 5) delivers consistent 300Mbps+ throughput in my testing at 5 metres from the router—adequate though not cutting-edge given Wi-Fi 6 prevalence. Bluetooth 5.0 with BLE support connected reliably to keyboards, mice, and audio devices without the dropout issues that plagued earlier Pi models.
Gigabit Ethernet provides reliable wired networking, achieving 940Mbps in iperf3 testing. Unlike the Pi 4’s USB-bottlenecked Ethernet, the Pi 5 dedicates bandwidth properly. For server applications and network-attached storage projects, wired connectivity remains preferable to Wi-Fi.
The 40-pin GPIO header maintains compatibility with the vast HAT ecosystem, though the board layout changed slightly. Most HATs designed for Pi 4 fit physically but check clearances around the new fan connector. The PCIe 2.0 x1 interface (accessible via the FFC connector after removing a surface-mount component) opens possibilities for NVMe SSDs and other expansion cards, though this requires technical confidence and voids warranty considerations.
Two USB 3.0 ports and two USB 2.0 ports provide adequate peripheral connectivity. The USB-C power input replaced the previous micro USB, improving power delivery reliability. The dual micro HDMI ports remain a minor annoyance—full-size HDMI would improve usability, and the micro connectors feel fragile with repeated plugging.

Who Should Buy the Raspberry Pi 5 8GB
The Raspberry Pi 5 8GB is best for makers and developers who need genuine desktop-replacement performance in a compact, expandable platform. If you’re running multiple applications simultaneously, developing software, or using the Pi as a daily computer, the 8GB configuration proves essential. The performance headroom supports demanding projects like computer vision, machine learning inference, and complex home automation systems that would overwhelm earlier models.
Students and educators benefit from the improved responsiveness when running IDEs, compiling code, and multitasking between documentation and development environments. The frustration of waiting for applications to launch or browser tabs to respond—common complaints with Pi 4—largely disappears. For learning programming, electronics, or Linux administration, the Pi 5 provides an affordable yet capable platform that doesn’t compromise the educational experience with sluggish performance.
Home automation enthusiasts running Home Assistant, Node-RED, or similar platforms will appreciate the headroom for expansion. My test installation managed 47 devices, multiple dashboards, and several automation scripts whilst maintaining sub-100ms response times. The system never felt constrained, and memory usage peaked at 4.2GB—comfortable on 8GB but potentially problematic on smaller configurations as systems grow.
Retro gaming enthusiasts gain access to more demanding emulation. PS1, N64, and Dreamcast emulation runs smoothly, whilst even some GameCube titles achieve playable framerates—territory previously requiring x86 hardware. The improved GPU handles shader effects and upscaling that enhance classic games beyond their original presentation.
Who Should Skip the Raspberry Pi 5 8GB
Budget-conscious users building simple single-purpose projects should consider whether they need Pi 5 performance. A Pi-hole ad blocker, print server, or basic weather station runs perfectly well on a Pi 3 or Pi 4. The Raspberry Pi Zero 2 W at £15 or Pi 4 4GB around £55 deliver better value for projects that don’t stress the system. Save your budget for projects that genuinely benefit from the upgraded specifications.
Users requiring absolute minimum power consumption should look elsewhere. The Pi 5’s 3.8W idle and 12W peak loads exceed earlier models, making it less ideal for battery-powered projects or always-on applications where electricity costs matter. The Pi 4 or Zero 2 W consume less power whilst still handling many server and IoT applications.
Anyone expecting plug-and-play simplicity without additional purchases will face disappointment. The board alone doesn’t include a power supply, case, cooling, or storage. Budget an extra £40-60 for a complete working system. For users wanting a turnkey solution, pre-configured mini PCs or the official Raspberry Pi 400 keyboard computer offer better out-of-box experiences.
Advanced users requiring maximum raw performance might find better value in alternatives like the Orange Pi 5 Plus or ODROID-N2+, which offer native NVMe support and slightly faster processors. The trade-off involves reduced software compatibility and smaller communities, but for specific high-performance applications, the compromises prove worthwhile.
At £81.71, the Raspberry Pi 5 8GB represents the best value for users who need the performance and will use the capabilities. Raspberry Pi 5 (8GB)
