Raspberry Pi 5 vs Mini PC for a Home Server: Honest Comparison

A Raspberry Pi 5 with 8GB of RAM can genuinely run a home server — I've been doing it, and I have the numbers to prove it works and where it falls short. An Intel N100 mini PC will outperform it in nearly every compute and I/O metric, but the gap matters less than you think for most self-hosting workloads.

My Actual Build and What I Measured

I'm running a Raspberry Pi 5 8GB Model B Rev 1.1 with 15Gi of usable RAM (the 16GB variant, reported by the kernel as 15Gi). The OS is Debian GNU/Linux 13 (trixie) on kernel 6.18.34+rpt-rpi-2712. Storage is a Fanxiang S501Q 512GB NVMe drive connected via the Pi 5's PCIe slot, booting directly from /dev/nvme0n1p2 — no SD card in the loop at all.

The PCIe connection runs at Gen 2 by default. Here are my actual fio results on this drive:

• Sequential read: 453 MB/s
• Sequential write: 438 MB/s
• Random 4K read IOPS: 16,433

Thermals with the official active cooler were remarkably stable. Idle SoC temperature sat at 49.4°C. After a sustained load test, the SoC actually reported 48.8°C — the fan simply keeps up. No throttling observed.

These numbers are real. Everything below about the N100 is based on published specs and community benchmarks, not hardware I've personally tested.

Storage: The Pi 5's Biggest Bottleneck (and How to Live With It)

The Fanxiang S501Q is rated for roughly 3,000 MB/s sequential reads on a Gen 3 x4 connection. I'm getting 453 MB/s. That's the PCIe Gen 2 x1 lane doing exactly what it's supposed to do — capping throughput at around 500 MB/s theoretical max. You can force Gen 3 in the Pi's firmware config, which reportedly pushes sequential reads past 800 MB/s, but stability varies by drive and I haven't switched because Gen 2 has been rock solid for me.

An N100 mini PC typically exposes a full Gen 3 x4 NVMe slot. Published benchmarks with comparable drives show 2,500-3,200 MB/s sequential reads. That's a 5-7x advantage on paper.

Does it matter in practice? For Docker containers running Jellyfin, Home Assistant, Nextcloud, or Pi-hole, the answer is mostly no. These workloads are dominated by random small I/O, not sequential throughput. My 16,433 random 4K read IOPS is plenty for a handful of containers serving a household. You'd feel the sequential gap during large file copies or database-heavy operations like Immich photo indexing.

CPU: ARM vs x86 Trade-offs

The Pi 5's Cortex-A76 quad-core is a capable chip, but it's not competing with the N100's four E-cores on multi-threaded compute. Published Geekbench scores put the N100 at roughly 1.5-2x the Pi 5's multi-core performance, depending on the workload. Single-threaded performance is closer but the N100 still leads.

Where this actually shows up in self-hosting:

• Transcoding: The N100 has Intel Quick Sync. The Pi 5 doesn't have a practical hardware transcode path for Jellyfin/Plex. If you need real-time video transcoding, the N100 wins categorically. This isn't close.
• Compilation/builds: Anything that hammers all cores — building containers, compiling from source — will be meaningfully faster on the N100.
• Lightweight services: Running Nginx, AdGuard Home, Wireguard, Vaultwarden, Gitea — honestly, both CPUs are loafing. You won't notice a difference.

A Note on RAM

My Pi 5 has 16GB, which matches most entry-level N100 mini PCs. The difference is the N100 boxes usually accept SO-DIMM upgrades to 32GB or more. The Pi's RAM is soldered. 16GB is generous for a home server today, but there's no upgrade path.

Power and Cost

I haven't measured wall power on my Pi build with a kill-a-watt, so I won't claim a specific wattage. Published figures put a Pi 5 under load at 8-12W total system draw (with NVMe and active cooler). N100 mini PCs reportedly draw 15-30W depending on the chassis, number of drives, and load. The delta is real but small — maybe $15-30 per year on a US electricity bill.

On purchase price: a Raspberry Pi 5 8GB plus official cooler, case, power supply, and a 512GB NVMe with HAT runs roughly $120-150 total. A decent Intel N100 Mini PC with 16GB RAM and a 500GB NVMe comes in around $150-200. The gap has narrowed considerably. The Pi's cost advantage is thinner than it used to be.

Who Should NOT Buy a Pi 5 for This

• You need hardware video transcoding. No Quick Sync equivalent. Full stop.
• You want more than one NVMe drive for mirroring or capacity. The Pi has one lane.
• You plan to run VMs seriously. KVM works on ARM, but most VM images target x86. The ecosystem friction is real.
• You're already close to 16GB of RAM in your current setup and might need to grow.

Who Should NOT Buy a Mini PC for This

• You value minimal attack surface and simplicity. The Pi boots from a single drive, draws negligible power, and the ARM ecosystem for containers is mature on Docker Hub.
• You're running fewer than ~10 lightweight containers. The N100 will be bored and you'll have spent more for headroom you don't use.
• GPIO and physical projects matter. If your home server also talks to sensors, relays, or Zigbee hats, the Pi's GPIO is an actual advantage.

If You Outgrow Either Option

Both machines hit a ceiling eventually. When that happens, you might consider a used SFF desktop (Lenovo ThinkCentre, Dell OptiPlex) which gives you full PCIe slots and ECC RAM options for roughly the same power budget as an N100 box. Or skip the hardware entirely and rent a small VPS from Hetzner Cloud or DigitalOcean for the services that benefit from fat bandwidth and uptime guarantees, keeping only storage-heavy or LAN-dependent services at home.

For off-site backups of either setup — and you should have off-site backups — Backblaze B2 B2 at $6/TB/month is hard to beat for a homelab.

Verdict

The Pi 5 is a genuine home server, not a toy — 453 MB/s reads, 16K random IOPS, and rock-steady 49°C thermals prove it handles real workloads without drama. The N100 wins on raw capability, especially transcoding and storage bandwidth, for only $30-50 more. Pick the Pi if you want the simplest, lowest-power path to self-hosting a handful of services; pick the N100 if you need transcoding or room to grow.
