Key Takeaways
- The G3 Plus runs Home Assistant and a small 1B–8B local model for about $180–230
- Intel N150: 4 cores, Intel UHD graphics, DDR4 upgradeable to 32 GB (replaceable SO-DIMM), no NPU
- A 7–8B model fits but runs slowly — this is a budget hub, not an AI box
- Standout vs the Beelink EQ14: 32 GB RAM ceiling (but only one 2.5GbE port and no USB-C)
- For a responsive 7B assistant, step up to a Beelink SER8
- Made in China — factor 2026 US/EU import measures into landed cost (see trade note)
Verdict — Who Should Buy It
Buy the GMKtec G3 Plus if you want a cheap Home Assistant box and you value a replaceable RAM slot that reaches 32 GB. For about $180–230 it is a solid budget entry to a local-first smart home, with a little more memory headroom than 16 GB-capped rivals. Do not expect a fast local assistant — the Intel N150 with single-channel DDR4 handles small models only.
Its single strongest use case is a compact, upgradeable Home Assistant hub that can also host a small model. If you want two network ports, the Beelink EQ14 is the better hub; if you want real AI speed, move up to a Ryzen box.

Local AI & LLM Performance
A 1B–8B model at 4-bit fits on the G3 Plus; a 7–8B model is usable but slow, and the 32 GB RAM option allows a larger context or a ~13B model at low throughput — all figures estimated from the verified hardware, not a measured benchmark. As with any N150 box, single-channel DDR4 bandwidth and the lack of an NPU are the limits.
- Good for lightweight local assistants, summarization, and automations on small models.
- Upgrading to 32 GB helps context length more than raw speed — the memory bandwidth is unchanged.
- No NPU and limited iGPU acceleration, so inference is CPU-bound.
- For heavier local AI (vision, a fast 7B assistant), choose a Ryzen box instead.
- See how to install Ollama to try a small model, and the local LLM hardware guide for context.
Pros & Cons
The G3 Plus trades networking for memory headroom versus the EQ14. Balanced view below.
- Pros
- Very affordable — about $180–230 for a Home Assistant box
- Replaceable DDR4 SO-DIMM upgradeable to 32 GB — more headroom than 16 GB-capped rivals
- Two storage slots: NVMe plus a separate SATA M.2 for bulk storage
- Low power: roughly 6 W idle, cheap to run 24/7
- Very compact (114 × 106 mm) and light (~361 g)
- Cons
- Only a single 2.5GbE port (the EQ14 has two)
- No USB-C port at all
- Single-channel DDR4 and no NPU — slow beyond a small model
- USB-A port speed is inconsistent across listings; verify before buying
Buyer Context: Tariffs & Availability (2026)
The G3 Plus is manufactured in China, so its landed price reflects 2026 trade measures — a reason to treat any price as a moving target. The facts below are buyer context, not editorial opinion.
- US: Section 301 tariffs on Chinese electronics remain in force in 2026; the separate 2025 "IEEPA" tariffs were struck down by the Supreme Court in February 2026 and replaced by a temporary, capped Section 122 tariff. The sub-$800 duty-free "de minimis" exemption for direct imports has also ended.
- EU (affects DE/FR): there is no broad EU tariff on finished mini PCs, but from July 2026 the €150 duty-free threshold on low-value direct-from-China parcels was removed and a small per-parcel handling fee added.
- Assumption (macro trend, not a per-product fact): redirected Chinese export capacity has kept availability of these brands high in the EU and US, which broadly supports competitive pricing.
- Net effect: verify the current price at the retailer before buying — the ~$180–230 figure here is indicative and date-stamped July 2026.
Where to Buy & Current Price
Prices move week to week, so check the live price rather than trusting a fixed figure. As of July 2026 the 16 GB / 512 GB G3 Plus sits around $180–230; the manufacturer page may show a placeholder price that does not reflect street listings.
- Confirm the RAM and storage capacity of the exact SKU — and that you can upgrade the SO-DIMM to 32 GB if you want the headroom.
Alternatives to Consider
If the G3 Plus is not the right budget box, consider these.
- Beelink EQ14 — the other budget N150 box; dual 2.5GbE networking but capped at 16 GB RAM
- Beelink SER8 — the step up: Ryzen 7 8845HS runs a real 7B assistant for about $650
- Minisforum UM890 Pro — mid-range Ryzen 9 with dual 2.5GbE and an eGPU port
- GEEKOM A9 Max — premium headroom box with a 128 GB RAM ceiling

Frequently Asked Questions
Can the GMKtec G3 Plus run local LLMs?
It can run small ones. A 1B–8B model at 4-bit fits, and a 7–8B model is usable but slow because of single-channel DDR4 bandwidth and the four-core N150. This is estimated from its verified hardware, not a fixed benchmark.
How big a model fits in its RAM?
With the base 16 GB, a 7–8B 4-bit model fits with headroom. Upgrading the SO-DIMM to 32 GB allows a longer context or a roughly 13B model at low throughput, though speed stays limited by memory bandwidth.
Is the RAM soldered or upgradeable?
Upgradeable. Despite some assumptions to the contrary, the G3 Plus uses a single replaceable DDR4 SO-DIMM slot, not soldered memory, and supports up to 32 GB. That upgrade path is a real advantage over budget boxes with fixed RAM.
Is the G3 Plus good for Home Assistant and always-on use?
Yes. It runs Home Assistant and add-ons well and draws about 6 W at idle, so it is cheap to leave on. Note it has a single 2.5GbE port, so it is less of a networking box than the dual-LAN Beelink EQ14.
Does the G3 Plus have a USB-C port?
No. This model has four USB-A ports and two HDMI outputs but no USB-C port, so plan your peripherals accordingly.
How much power does the G3 Plus use?
About 6 W at idle and roughly 21 W under load, so continuous operation costs very little. This efficiency is a key reason to choose an N150 box as a hub.
G3 Plus or Beelink EQ14?
Both use the Intel N150. The G3 Plus supports up to 32 GB of RAM, which helps context and larger small-models; the EQ14 caps at 16 GB but adds a second 2.5GbE port. Choose by whether you value memory headroom or dual networking.
Where is the GMKtec G3 Plus made, and does that affect price?
It is manufactured in China. In 2026 US import measures (Section 301 tariffs, the end of the sub-$800 de minimis exemption) and the EU removal of the €150 low-value parcel exemption can affect landed cost, so check the current retailer price rather than relying on a fixed number.
