The Raspberry Pi 5 changed the home server equation. With 2-3x the CPU performance of the Pi 4 and native NVMe support, it's a legitimate always-on agent host for workloads that pushed the Pi 4 to its limits. Here's what changes in the setup and what stays the same.
Pi 5 vs Pi 4 for OpenClaw
If you're already running OpenClaw on a Pi 4 and it's handling your workload fine, don't upgrade. The Pi 5 matters when you're hitting CPU limits — typically when running Playwright browser automation, multiple concurrent skills, or channels that trigger frequently.
- CPU: Cortex-A76 vs Cortex-A55 — roughly 2-3x performance for compute-heavy tasks
- Storage: Native PCIe NVMe via M.2 HAT+ vs USB 3.0 SSD on Pi 4 — 5-10x faster random I/O
- RAM bandwidth: LPDDR4X on Pi 5 — faster than Pi 4's LPDDR4, helps with multi-skill concurrent execution
- Power: 5-12W vs 3-7W — requires the official 27W USB-C power supply
Setup & Installation
The installation process is identical to Pi 4. Flash Raspberry Pi OS Lite 64-bit (Bookworm) using Raspberry Pi Imager. Enable SSH in advanced settings. Boot and connect via SSH.
# Same install steps as Pi 4:
sudo apt update && sudo apt full-upgrade -y
sudo apt install python3.11 python3.11-venv python3-pip -y
sudo useradd -m -s /bin/bash openclaw
sudo su - openclaw
python3.11 -m venv /home/openclaw/venv
source /home/openclaw/venv/bin/activate
pip install openclaw
openclaw init
The Pi 5 requires the updated eeprom for NVMe boot. Run sudo rpi-eeprom-update -a and reboot before attaching the M.2 HAT+.
NVMe SSD Configuration
# After attaching M.2 HAT+ and NVMe SSD:
# In raspi-config, enable PCIe:
sudo raspi-config
# Advanced Options > PCIe Speed > PCIe Gen 2
# Check SSD is detected
lsblk # should show nvme0n1
# For boot from NVMe, use Raspberry Pi Imager to flash OS directly to NVMe
# Or copy SD card to NVMe:
sudo dd if=/dev/mmcblk0 of=/dev/nvme0n1 bs=4M status=progress
# Update boot order in eeprom
sudo rpi-eeprom-config --edit
# Set BOOT_ORDER=0xf416 (NVMe first)
Workflow Optimization
With the Pi 5's additional headroom, you can enable workloads that were impractical on Pi 4:
# openclaw.yaml — Pi 5 optimized settings
runtime:
max_concurrent_skills: 4 # up from 2 on Pi 4
skill_timeout: 45
log_level: info # can afford more verbose logging with NVMe
model:
provider: anthropic
model: claude-sonnet-4-6 # can use faster models vs haiku-only on Pi 4
skills:
playwright:
enabled: true # usable on Pi 5; too slow on Pi 4
Common Mistakes
Using the Pi 4 power supply with Pi 5 is the most common setup mistake. The Pi 4 uses 5V/3A; the Pi 5 needs 5V/5A. Under OpenClaw load, the Pi 5 draws more than the Pi 4 supply can provide.
- Skipping the eeprom update — the Pi 5 ships with older eeprom that doesn't fully support NVMe boot. Always run rpi-eeprom-update before configuring NVMe boot.
- Not enabling PCIe Gen 2 — the M.2 HAT+ defaults to Gen 1 speed in older eeprom versions. Enable Gen 2 in raspi-config for full NVMe performance.
- Running too many concurrent local models — even on Pi 5, running two simultaneous Ollama instances causes memory pressure. Stick to one local model instance if you go the local inference route.
- Same config as Pi 4 — don't copy Pi 4 configs that limit concurrent skills to 2. The Pi 5 can handle 4 comfortably. Increase the limits to actually benefit from the hardware.
Frequently Asked Questions
Is the Pi 5 worth upgrading from Pi 4 for OpenClaw?
For most users, Pi 4 4GB is sufficient. Upgrade for 3+ simultaneous channels, Playwright automation, or faster cold starts.
Does the Pi 5 support NVMe storage?
Yes. Via the official M.2 HAT+ and PCIe 2.0 x1 interface — dramatically faster than USB SSD or SD card.
How much RAM for Pi 5?
4GB for standard use; 8GB for Playwright, local models, or multiple concurrent skill workloads.
Can I run Ollama local models on Pi 5?
Yes — expect 3-8 tokens/second with small models. Usable for simple tasks, still slower than hosted APIs.
What OS should I use?
Raspberry Pi OS Lite 64-bit (Bookworm/Debian 12). 64-bit is mandatory; Lite saves RAM by skipping the desktop.
Does the Pi 5 run cooler than Pi 4?
Similar temperatures under sustained load with appropriate cooling. The official active cooler is recommended for 24/7 OpenClaw workloads.
