N100 Mini PC vs Raspberry Pi 5: Cost, Watts and Speed

The Pi 5 runs Broadcom's BCM2712 with four Arm Cortex-A76 cores at up to 2.4GHz. The N100 runs four Intel Gracemont cores at up to 3.4GHz with three times the last-level cache. Per core and per clock the two designs are in the same league; the N100's higher clocks and bigger cache put it ahead in most CPU work.

The bigger gaps are around the cores.

• Instruction set: the N100 is x86-64, so Proxmox, Windows 11, TrueNAS and any Docker image run unmodified. The Pi 5 needs Arm builds, which most popular containers now offer but not all.
• Memory: the Pi 5 tops out at 16GB soldered. N100 boxes take a SO-DIMM or LPDDR5; Intel lists 16GB, and single 32GB sticks are widely reported to work.
• Storage: the Pi boots from microSD unless you add an M.2 board on its single PCIe 2.0 lane. N100 boxes ship with an M.2 SSD, often with a second slot.
• Video: the Pi 5 decodes HEVC in hardware and little else. The N100's Quick Sync engine decodes AV1, HEVC, VP9 and H.264 and encodes too.

The Pi's strengths sit elsewhere: a 40-pin GPIO header, a huge accessory ecosystem, official support for years, and the lowest idle draw of anything here.

A dependable 24/7 Pi 5 setup needs more than the board.

1. Power supply: the official 27W USB-C unit. Weaker supplies limit USB current and trigger warnings.
2. Cooling: the Active Cooler or a case with a fan, since the Pi 5 throttles under sustained load without one.
3. Case: for dust and handling.
4. Storage: a high-endurance microSD at minimum; an M.2 add-on board and an NVMe SSD for anything that writes a lot, such as a Home Assistant database.

With those parts, an 8GB Pi 5 lands in the same price band as an entry N100 box, and a 16GB Pi 5 goes past it. The N100 box arrives with a case, a cooler, a supply, an SSD and often a Windows licence already in the price.

Current price bands for N100 mini PCs by memory and storage make that comparison concrete. Memory prices have pushed both sides up since 2025, so check both on the same day.

A whole N100 mini PC typically idles somewhere between 6W and 10W, depending on the board, the SSD, the network chip and how deep the BIOS lets the chip sleep. Under full load it can reach 20W to 30W for short bursts, set by the maker's power limits.

Over a year of 24/7 running, each extra watt costs about 8.8kWh. A 5W idle gap therefore works out to roughly 44kWh a year: noticeable on a spreadsheet, small on a household bill.

• Mostly idle jobs: Home Assistant with a few integrations, Pi-hole, a VPN endpoint. The Pi's lower floor saves a little every hour.
• Bursty jobs: Plex transcodes, backups, camera detection. The N100 finishes sooner and drops back to idle, so the gap narrows.
• Many jobs at once: one N100 box replacing two or three Pis usually draws less than all of them together.

The N100 idle and load wattage figures go model by model. For the lowest N100 idle, look for a box with one NVMe drive, no spinning disk, and ASPM enabled in the BIOS.

The difference appears as the install grows. Home Assistant keeps its history in a database that writes constantly, which punishes microSD cards; an N100 box's NVMe SSD shrugs it off. A Pi 5 fixed with an NVMe board narrows that gap.

Heavier add-ons shift the balance further.

• Frigate NVR: on the N100, object detection can run on the integrated GPU through OpenVINO and video decoding on Quick Sync. The Pi 5 generally needs a separate accelerator such as a Coral for more than a camera or two.
• Local voice: speech-to-text with Whisper and text-to-speech with Piper run noticeably faster on four x86 cores at 3.4GHz, which is the difference between a snappy and a sluggish voice assistant.
• Virtualisation: on an N100, Proxmox can host Home Assistant OS in a VM next to other services. Proxmox is x86-only.

Both take the usual Zigbee, Z-Wave and Thread USB sticks; plug them in through a short extension cable to keep them clear of USB 3 interference. For a full homelab stack on one box, see Home Assistant, Proxmox, Plex and NAS on an N100.

A few N100 firewall and industrial boxes expose GPIO pins or RS232 serial ports, but nothing close to the Pi's documented header and library support. If the project reads sensors, drives relays or talks SPI and I2C, keep the Pi.

• Choose the Pi 5 for robotics, sensor hubs, camera projects, retro builds inside a case, or a board you will mount inside something else.
• Choose the Pi 5 when idle draw matters most, such as a solar or battery-powered node.
• Choose an N100 box for Home Assistant with cameras or voice, media serving, Proxmox, a NAS, a firewall or a desktop you will sit in front of.
• Choose an N100 box when you want 16GB or more, a real SSD and a case in one purchase.

Many homelabs end up with both: the N100 box as the always-on server, the Pi as a sensor node or a Zigbee bridge in a far corner. That split plays to each machine's strengths.

For N100 boxes built for a network role instead, the four-port firewall appliances are the next step up from a Pi running as a router.
