Raspberry Pi 5 review: faster silicon, higher stakes, real-world limits

What changed from Pi 4: genuine performance, new I/O

The Raspberry Pi 5 replaces the 1.8GHz Cortex-A72 cores of the Pi 4 with 2.4GHz Cortex-A76 silicon, a three-generation architectural leap that delivers between two and three times the single-threaded performance in independent benchmarks. Multi-core workloads show similar gains, with Sysbench tests completing 75 to 80 percent faster. The VideoCore VII GPU running at 800MHz instead of 500MHz doubles graphics scores and enables smoother 4K60 HDR video decode, making desktop use noticeably more fluid.

The board introduces a PCIe 2.0 x1 slot via the custom RP1 southbridge chip, a first for mainline Raspberry Pi hardware. With an M.2 HAT adapter users can boot from NVMe SSDs that deliver read speeds up to ten times faster than microSD cards and eliminate the write-endurance problems that plagued SD-based server deployments. The USB 3.0 ports now reach their rated 5Gbps speeds thanks to the RP1, and the microSD slot supports SDR104 mode for doubled peak throughput. Two four-lane MIPI connectors replace the prior single-camera single-display setup, allowing any combination of two cameras or displays.

Real-time clock support with a CR2032 battery, an onboard power button for clean shutdown, and a fan header with PWM control round out the quality-of-life improvements. These changes address long-standing complaints about the Pi 4's I/O bottlenecks and usability gaps, but they come at the cost of higher power draw, mandatory cooling, and incompatibility with older cases and camera cables.

Pricing reality in 2026: memory inflation bites hard

When the Pi 5 launched in late 2023 the 4GB model sold for 60 dollars and the 8GB for 80 dollars. By December 2025 the Raspberry Pi Foundation announced the first round of LPDDR4X price increases driven by AI infrastructure demand, and in February 2026 a second hike pushed the 4GB to 75 dollars, the 8GB to 95 dollars, and the flagship 16GB variant to 205 dollars. The new 1GB entry model holds the line at 45 dollars but trades RAM for affordability in a way that limits real-world server use.

These are board-only prices. A realistic deployment requires the official 27W USB-C power supply at roughly 12 dollars, an active cooler for another 5 dollars, an M.2 HAT for NVMe at 12 dollars, a 512GB NVMe SSD at 40 to 50 dollars, and a case. The total bill of materials for a usable 8GB Pi 5 server lands between 230 and 260 dollars depending on storage and case choice. At that price refurbished Dell Optiplex or Lenovo ThinkCentre Tiny PCs with Intel Core i3 or i5 CPUs, 16GB of DDR4, and 256GB SSDs appear on eBay for 200 to 220 dollars, offering more CPU performance, double the RAM, and x86 software compatibility.

The Pi 5 retains advantages in power efficiency, drawing 5 to 8 watts idle versus 15 to 20 watts for a mini PC, and the GPIO ecosystem has no x86 equivalent. But the value equation has shifted. For hobbyists running Pi-hole or a single Docker stack the board still makes sense. For users planning heavier self-hosting workloads or buying multiple units the price gap to alternatives has narrowed uncomfortably.

Self-hosting workloads: where it shines, where it struggles

The Pi 5 excels at lightweight always-on services. Pi-hole, AdGuard Home, WireGuard, Vaultwarden, and Home Assistant run comfortably on the 4GB or 8GB models with minimal CPU load and modest memory footprints. Docker Engine and Podman both support ARM64 natively, and popular self-hosting images from LinuxServer.io, the official Home Assistant containers, and most major open-source projects publish multi-arch builds. Real-world reports describe stable multi-month uptimes running half a dozen containerized services simultaneously.

Heavier workloads expose the board's limits. Nextcloud with multiple concurrent users, Jellyfin or Plex media servers attempting real-time transcoding, and memory-intensive databases begin to saturate the four Cortex-A76 cores. The lack of SMT means four threads is the ceiling, and ARM64 performance per thread still lags behind modern x86 chips in many workloads. Some niche self-hosted applications publish only x86 Docker images, forcing users to seek alternatives or build custom ARM images. The 16GB model helps with memory-constrained tasks like running local AI models via Ollama, but thermal throttling without active cooling remains a persistent problem under sustained load.

Community guides document successful deployments of GitHub Actions runners, n8n workflow automation, Dockge container management, and even lightweight Kubernetes clusters on Pi 5 hardware. The ARM64 architecture and four-core limit mean these setups work but rarely match the headroom of an equivalently priced x86 mini PC. The Pi's sweet spot remains single-user or small-household infrastructure where low power draw and the GPIO ecosystem justify the trade-offs.

Active cooling is not optional

The Raspberry Pi 5 generates significantly more heat than the Pi 4 under load. Without active cooling the SoC throttles at 65 degrees Celsius, clocking down from 2.4GHz to maintain thermal limits. Independent thermal testing shows the board reaching 78 degrees Celsius under sustained CPU stress without a fan, dropping to 58 degrees with the official active cooler installed. Multi-core benchmarks run 15 to 20 percent slower without adequate airflow, and sustained Docker builds or database queries trigger repeated throttling events.

The official active cooler costs roughly 5 dollars and connects to the onboard fan header with PWM control, spinning up automatically under load and remaining near-silent at idle. Third-party options like the Argon ONE V3 case or tower-style coolers from 52Pi offer better thermal performance for users planning continuous heavy workloads or overclocking experiments. Passive cooling with heatsinks alone is insufficient for server use; reviewers consistently report throttling within minutes of stress testing.

This cooling requirement adds cost and complexity. The Pi 4 could run passively in many scenarios; the Pi 5 cannot. For always-on deployments in warm environments or enclosed spaces budget for active cooling from the start or plan for degraded performance.

Ecosystem and longevity

The Raspberry Pi platform benefits from over a decade of community investment. Raspberry Pi OS receives regular updates, the Foundation publishes detailed documentation and compliance certificates, and the standard 40-pin GPIO header ensures compatibility with hundreds of HAT accessories for everything from PoE power to AI accelerators. The RP1 southbridge is the first major in-house silicon from the Foundation, signaling tighter vertical integration and potentially better long-term support than reliance on third-party chips.

Software longevity appears strong. The Pi 5 runs the latest Raspberry Pi OS releases based on Debian 13, and the Foundation has committed to supporting the board through future OS updates. The ARM64 architecture is well-established in the container ecosystem, and major self-hosting projects show no signs of dropping ARM support. The board's popularity ensures that community guides, troubleshooting forums, and third-party accessories will remain plentiful for years.

The pricing volatility introduced by memory market dynamics is the primary longevity concern. If LPDDR4X costs remain elevated or climb further the Pi 5 risks becoming a niche choice rather than the default tinkering platform. The Foundation has stated that price increases are temporary and will be unwound when memory markets stabilize, but no timeline has been provided. For buyers in mid-2026 the board's future value depends heavily on factors outside the Foundation's control.
