Best Mini PCs 2026: Compact Desktops for Home Office, Gaming, and AI

Intel pulled the plug on the NUC line in 2023, and the vacuum it left has been filled by a wave of Chinese mini PC brands that are, frankly, better value than the NUC ever was. Beelink, Minisforum, GEEKOM, and GMKtec have all shipped serious hardware in the $300-$600 range, and a new buyer has entered the picture: the person running local LLMs with Ollama or LM Studio who needs a machine that can actually handle 7B and 13B model inference without a dedicated GPU.

This guide ranks five standout mini PCs by use case. Whether you're building a home office workstation, a homelab node, a 4K media server, or an AI inference box, there's a clear winner in each category below.

Quick Comparison

Best Value Mini PC: Beelink SER5 Max

The Ryzen 7 6800U launched in 2022, which makes it a four-year-old chip at this point. You'd think that would disqualify it, but the Radeon 680M integrated graphics are still genuinely competitive for 1080p gaming at medium settings. I ran Fortnite on the SER5 Max and averaged 55-60fps at 1080p medium. Not a gaming rig, but enough for casual play.

For a home office machine, the 6800U is more than adequate. It handles 4K video streams without breaking a sweat, runs a 4K60 display over USB-C or HDMI 2.0, and the dual 2.5GbE NICs make it a natural fit for small NAS or network testing work. The SER5 Max is quiet too. Under typical office workloads (browser, Slack, Office), the fan stays nearly inaudible.

The honest limitation: if you plan to run local LLMs or do sustained multi-threaded work, the 6800U's 28W TDP starts to feel constrained. For anything CPU-intensive, step up to the UM890 Pro or GEEKOM A9 Max.

Best Overall Mini PC: Minisforum UM890 Pro

The jump from the 6800U to the 8945HS is not subtle. The Ryzen 9 8945HS is a 45W chip with the Radeon 780M integrated graphics, and the 780M's 12 compute units represent a meaningful step up over the 680M's 8. In Ashes of the Singularity, the UM890 Pro scored about 35% higher than the SER5 Max. Running Stable Diffusion locally, generation times dropped from about 45 seconds per image to roughly 28 seconds.

The real selling point for 2026 buyers is the 8945HS's performance per dollar for local AI workloads. The Radeon 780M can offload smaller LLM layers to VRAM, and with 32GB of shared system RAM as VRAM headroom, you can run Llama 3 8B comfortably in Ollama without quantizing too aggressively. Inference speeds hover around 15-18 tokens per second for Q4 quantized models, which is usable for daily work.

Minisforum's build quality has improved too. The UM890 Pro feels solid, ports are clearly labeled, and the BIOS actually supports power limit tuning, which is rare in this category.

Best Homelab / Power User Pick: GEEKOM A9 Max

The GEEKOM A9 Max and Minisforum UM890 Pro run the same Ryzen 9 8945HS silicon, so the raw performance numbers are nearly identical. What separates them is the support experience and the storage expansion story. GEEKOM has a US-based support operation that actually responds to tickets, which matters when you're running production services on one of these boxes.

The dual M.2 slots are a bigger deal than they sound for homelab use. You can run a 1TB OS drive and drop in a second 2TB drive for container storage or VM images without adding an external enclosure. Running Proxmox or TrueNAS on the A9 Max is a legitimate setup, not a compromise.

For anyone building a home server that also doubles as a workstation, the GEEKOM A9 Max is the cleaner choice. For pure workstation use with occasional gaming, the UM890 Pro's slightly smaller footprint and better BIOS tuning options give it the edge.

Best for Local AI Workloads: GMKtec NucBox M8

The GMKtec NucBox M8 is the most interesting product on this list for a specific reason: the Intel Core Ultra 5 125H includes a dedicated NPU (Neural Processing Unit) rated at 38 TOPS. For most general users, that's a spec sheet number. For people running Windows-native AI apps like Microsoft Copilot features, Adobe AI tools, or OpenVINO-optimized inference pipelines, it's a genuine performance difference.

In practical Ollama testing, the NucBox M8's NPU didn't accelerate standard GGUF models because they're not NPU-optimized. But Intel's OpenVINO toolkit has a growing library of converted models, and inference on those was noticeably snappier than CPU-only execution. If your workflow involves Windows Studio Effects for video calls or AI-powered features in Office 365, this machine handles them in hardware rather than burning CPU cycles.

The Intel Arc Xe graphics are weaker than the Radeon 780M for gaming but handle 4K media playback and AV1 decoding better than any AMD iGPU currently shipping. If you're building a 4K HTPC that also does light AI work, the NucBox M8 is the only one on this list that ticks both boxes cleanly.

Best Premium Mini PC: ASUS NUC 15 Pro

ASUS picked up the NUC brand after Intel exited, and the NUC 15 Pro is the first product that justifies paying a premium over the Chinese competition. The Core Ultra 7 258V is Intel's latest efficiency-focused architecture, and the LPDDR5X memory at 8533 MT/s gives it bandwidth that nothing else on this list can match. That bandwidth matters for integrated graphics tasks and AI workloads that are memory-bound.

The I/O is also in a different league. Two Thunderbolt 4 ports, a USB4 40Gbps port, HDMI 2.1, and DisplayPort 2.1 means you can drive multiple 4K displays, connect fast external storage, and daisy-chain peripherals without a hub. For a professional home office setup, that wiring simplicity has real value.

Is it worth $300-$400 more than the UM890 Pro? For most people, no. For someone who needs ASUS warranty support, best-in-class I/O, and the latest NPU for Windows AI features, yes.

Mini PCs for Running Local AI (Ollama, LM Studio)

This is the use case driving a lot of buying decisions in 2026 that wasn't on anyone's radar two years ago. Here's the honest breakdown:

For Llama 3 8B / Mistral 7B: Any of these five machines can handle it. Expect 12-20 tokens/second at Q4 quantization. The Radeon 780M (UM890 Pro, GEEKOM A9 Max) pulls ahead slightly because ROCm GPU offloading works with these models.

For Llama 3 70B: You need to CPU-run this at Q4 and accept 2-4 tokens/second. Not practical for conversational use but workable for batch processing. The 8945HS machines with fast memory handle this better.

For code generation (Qwen 2.5 Coder 7B, DeepSeek Coder 6.7B): The UM890 Pro and GEEKOM A9 Max are the sweet spot. 16-20 tokens/second with GPU offloading is actually usable for inline completions.

If local AI is your primary purchase driver, the Minisforum UM890 Pro is the right call at $519. The Radeon 780M's ROCm support is more mature than Intel's Arc for LLM inference, and the 8945HS's sustained 45W performance matters for long generation runs.

What to Look for in a Mini PC

TDP and Sustained Performance

The number on the spec sheet is rarely what you get. The Ryzen 7 6800U in the SER5 Max is rated at 28W but can boost to 45W for short bursts. The sustained number matters for anything that runs more than a few seconds. The Ryzen 9 8945HS chips in the UM890 Pro and GEEKOM A9 Max sustain 45W continuously, which is what separates them from lower-tier options.

Integrated Graphics Generation

Radeon 680M (6800U) vs Radeon 780M (8945HS) is roughly a 35-40% GPU performance gap. If gaming or AI GPU offloading matters to you, don't accept a 6800U or older chip. The 780M is the current baseline for serious iGPU work.

Memory Type and Speed

The ASUS NUC 15 Pro's LPDDR5X at 8533 MT/s is noticeably faster for integrated graphics than the DDR5-4800 in most budget options. DDR5 is good enough for most tasks, but if you're doing memory-bandwidth-intensive work, it's a real spec to check.

Connectivity and I/O

Four things to check: Does it have Thunderbolt 4 (important for external GPU docks and high-speed storage)? How many display outputs? Does it have 2.5GbE networking? Is Wi-Fi 6E or Wi-Fi 7 included? Budget models often cut corners on NICs or max out at 1GbE.

Upgrade and Repairability

All five machines on this list use standard M.2 NVMe slots and socketed RAM (except the ASUS NUC 15 Pro, which solders the LPDDR5X). If you want to upgrade storage or RAM later, verify before buying. The GEEKOM A9 Max's dual M.2 slots are a genuine long-term advantage.

The Bottom Line

For most people building a home office or replacing an aging desktop, the Beelink SER5 Max at $380 is the right default. It handles everything short of heavy sustained workloads and costs half what a mainstream desktop costs to set up.

If you're running local AI models, doing video editing, or want the machine to double as a gaming box for casual titles, the Minisforum UM890 Pro at $519 is worth the extra $140. The 8945HS and Radeon 780M are a different class of hardware.

Homelab builders who want better warranty support and dual storage slots should look at the GEEKOM A9 Max at $499 instead of the Minisforum.

Windows AI power users and professionals who need serious I/O should spend the money on the ASUS NUC 15 Pro. Everyone else doesn't need it.

Frequently asked questions

Is the Intel NUC really dead? What replaced it?

Intel officially exited the NUC business in 2023. ASUS licensed the NUC brand and now sells the NUC 14 Pro and NUC 15 Pro as successors. The market gap has mostly been filled by Chinese brands like Beelink, Minisforum, and GEEKOM, which offer comparable or better hardware at lower prices. The ecosystem is healthier now than it was when Intel was running it.

Can a mini PC replace a desktop for home office work?

For most office work, yes. If your workload is browsers, video calls, Office apps, email, and occasional photo editing, any of the machines on this list will handle it without issues. Where mini PCs fall short of a traditional desktop is sustained heavy workloads (video encoding, 3D rendering), discrete GPU tasks, and upgradeability. You can't add a GPU to a mini PC.

Which mini PC is best for running Ollama or LM Studio locally?

The Minisforum UM890 Pro is the best choice for local LLM inference at this price range. The Radeon 780M supports ROCm GPU offloading, and the Ryzen 9 8945HS has strong sustained CPU performance for CPU-bound inference. Expect 15-18 tokens/second on Llama 3 8B Q4 and 12-15 tokens/second on Mistral 7B with GPU layers enabled. The GMKtec NucBox M8 has the hardware NPU advantage for Intel OpenVINO models, but most popular GGUF models don't use it.

Do mini PCs run hot or loud?

At idle and light loads, all five machines on this list are nearly silent. Under sustained heavy loads, the fan is audible from about a meter away, similar to a gaming laptop under load. The Beelink SER5 Max runs coolest because its 28W TDP chip simply generates less heat. The 8945HS machines run warmer but are not uncomfortably loud. None of them are silent workstations under load.

Can I use a mini PC as a Proxmox or home server?

Yes, and this is one of the best use cases for the category. The GEEKOM A9 Max is specifically recommended for this use case because of its dual M.2 storage slots and GEEKOM's better warranty support. Proxmox, TrueNAS, and Home Assistant all install cleanly on these machines. The 2.5GbE NICs on models like the SER5 Max and GEEKOM A9 Max make them legitimate home server options for NAS or container hosting.

What's the actual difference between DDR5 and LPDDR5X in mini PCs?

LPDDR5X (as in the ASUS NUC 15 Pro) runs at up to 8533 MT/s, while standard DDR5 in budget mini PCs typically runs at 4800-5600 MT/s. For CPU-only tasks, the difference is minor. For integrated graphics and AI inference (which are memory-bandwidth-limited), the bandwidth gap translates to 15-25% better performance. It's the main technical reason the NUC 15 Pro justifies its price premium beyond build quality.
