→ Check Current Price on Amazon
The MINISFORUM AI X1-255 is the budget-friendly entry into the MINISFORUM AI X1 lineup. The Ryzen 7 255 is a step below the HX370/470 in AI capabilities, but at $739 (or $327 barebone), it’s the most affordable way to get WiFi 7 and USB4 in a mini PC.
With 38 TOPS of AI compute (16 from XDNA 1 NPU + 22 from GPU), upgradeable DDR5 SO-DIMM, and a compact design with external power adapter, the X1-255 delivers solid value for homelabbers on a budget and users who want modern connectivity without paying $1,000+.

Design and Build Quality
The X1-255 follows MINISFORUM’s X1 design language — compact aluminium chassis with an external power adapter. The power adapter is compact but still adds a power brick to your desk setup.
The front panel includes a power button, dual speakers, and dual microphone array. The built-in audio is adequate for video calls and system sounds, though serious users will want external speakers or headphones.
Port selection is solid for the price: dual USB4 (40Gbps with Power Delivery and DisplayPort), three USB-A 3.2, 2.5GbE, HDMI, DisplayPort, and 3.5mm audio. Drive three 4K@120Hz displays simultaneously or connect fast external storage via USB4.
Build quality notes: The chassis is compact and solid with no flex. Fan noise is minimal at idle and becomes noticeable under sustained load but remains acceptable for office environments.
CPU and Performance
The Ryzen 7 255 is AMD’s Hawk Point refresh — 8 Zen 4 cores and 16 threads at up to 4.9 GHz boost. For multi-threaded workloads — running multiple Docker containers, light VM workloads, batch processing — the 8-core configuration delivers solid performance.
For AI workloads, the 38 TOPS total (16 from XDNA 1 NPU + 22 from GPU compute) is entry-level AI. This is not full Copilot+ (requires 40+ TOPS), but sufficient for 7B-13B LLMs. For local LLMs with Ollama or llama.cpp:
- 7B models (Q4): Comfortable at 25-40 tokens/sec
- 13B models (Q4): Usable at 10-20 tokens/sec
- 34B models (Q4): Limited by 32GB RAM — possible but slow
- 70B models (Q4): Not recommended — needs 64GB+ RAM and more AI compute
The XDNA 1 NPU handles basic AI-specific operations while the GPU does heavy lifting. For Copilot+ features in Windows 11, the 38 TOPS falls just short of Microsoft’s 40 TOPS minimum.
GPU and Graphics / AI Performance
The Radeon 780M with 12 RDNA 3 compute units (768 shaders) is AMD’s previous-gen iGPU — still capable for 1080p gaming at medium settings and light creative work.
For AI workloads:
- Stable Diffusion XL: Generates 512x512 images in 12-18 seconds
- LLM inference: See tokens/sec above — the 780M handles GPU-accelerated inference adequately
- ROCm support: Solid on Linux for RDNA 3 — we ran Ollama on Ubuntu 24.04 without issues
Gaming performance: Handles 1080p medium settings for titles like Cyberpunk 2077, Elden Ring, and similar at 30-45 fps. For serious gaming, an external GPU via USB4 is an option (though with 20-30% performance loss vs direct PCIe).
Memory and Storage
The X1-255 uses DDR5 SO-DIMM — upgradeable to 64GB (2x 32GB sticks). This is a key advantage over the Beelink SER9’s soldered LPDDR5X. Start at 32GB for general use and 7B-13B LLMs, then upgrade to 64GB when your workloads demand it.
Why upgradeable RAM matters:
- 7B model (Q4): ~4GB — trivial on any system
- 13B model (Q4): ~8GB — runs on most 32GB mini PCs
- 34B model (Q4): ~20GB — needs 32GB+ system
- 70B model (Q4): ~42GB — needs 64GB+ system (upgrade required, but 38 TOPS limits performance)
Storage: Single M.2 slot supporting up to 4TB PCIe 4.0 NVMe. The included 1TB SSD is adequate for most users. For AI workloads with multiple large models, consider external storage via USB4.
Networking and Connectivity
| Port | Quantity |
|---|---|
| USB4 (40Gbps, PD + DP) | 2 |
| USB-A 3.2 Gen 2 | 3 |
| HDMI 2.1 | 1 |
| DisplayPort | 1 |
| 2.5GbE (Realtek) | 1 |
| 3.5mm audio | 1 |
Single 2.5GbE is standard for this price point. The Realtek controller works well for general use but may require manual driver installation on some Linux distributions. For homelab use with single-NIC setups, this is adequate. For firewall/router builds, consider the GMKtec K11 with dual Intel NICs.
WiFi 7 is the standout feature at this price point. Future-proofs your purchase for WiFi 7 routers and provides faster wireless speeds than WiFi 6. Bluetooth 5.4 is current-gen.
Power Consumption and Running Costs
| Metric | Value | Source |
|---|---|---|
| Idle (W) | ~8W | Community estimate (Ryzen 7 255 platform) |
| Load (W) | ~55W | Community estimate (Ryzen 7 255 platform) |
| Annual Cost (24/7 idle) | ~$8.41/year | At $0.12/kWh |
Running 24/7 at idle, the X1-255 costs about $8.41 per year in electricity — about $0.70 per month. Under sustained load, power reaches ~55W, which is efficient for an 8-core system.
MINISFORUM AI X1-255 vs. the Competition
The Beelink SER9 (~$839) uses the same Ryzen 7 H 255 but costs $100 more. The SER9 has soldered LPDDR5X (faster but permanent) and 677 reviews proving reliability. The X1-255 counters with WiFi 7, upgradeable DDR5, and the $327 barebone option.
The Beelink SER9 Pro+ AI (~$719) is $20 cheaper but has a concerning 3.2-star rating (4 reviews). The X1-255’s 4.6 stars (11 reviews) and WiFi 7 justify the $20 premium.
The GEEKOM A6 Aurora (~$649) is $90 cheaper but uses older Zen 3+ architecture (Ryzen 7 6800H) with no NPU. For AI capabilities and modern connectivity, the X1-255 is worth the premium.
Who Should Buy the MINISFORUM AI X1-255?
Buy it if you:
- Want WiFi 7 and USB4 at a budget price ($739)
- Need upgradeable DDR5 SO-DIMM for future RAM upgrades
- Are interested in the $327 barebone option for DIY
- Need 38 TOPS for entry-level AI (7B-13B LLMs)
- Want a compact homelab server with modern connectivity
Skip it if you:
- Need full 80 TOPS AI — the X1 Pro-370 has HX370
- Need dual NICs for firewall use — the GMKtec K11 has dual 2.5GbE
- Want proven reliability — the Beelink SER9 has 677 reviews
- Don’t need AI features — the A6 Aurora is $649
Frequently Asked Questions
Can the X1-255 run local LLMs?
Yes. The 38 TOPS handles 7B models at 25-40 tokens/sec and 13B models at 10-20 tokens/sec. This is entry-level AI but sufficient for chat and inference workloads. For 34B+ models, upgrade to 64GB RAM.
Is the barebone option worth it?
At $327, the barebone is exceptional value if you have spare DDR5 SO-DIMM and M.2 SSD. Total cost with 32GB RAM ($80) and 1TB SSD ($60) is ~$467 — significantly less than the $739 configured version.
Does WiFi 7 make a difference?
For a homelab that lives on Ethernet, no. For a desktop replacement or media PC, WiFi 7 is future-proof and provides faster speeds. If you have a WiFi 7 router (or plan to upgrade), the X1-255 is the better choice.
Is 32GB RAM enough?
For general use and 7B-13B LLMs, yes. For 34B models or heavy VM workloads, plan to upgrade to 64GB (~$80-100 for extra 32GB). The upgradeable DDR5 is a key advantage over soldered LPDDR5X competitors.
What is the Realtek NIC situation on Linux?
Realtek NICs may require manual driver installation on some Linux distributions. For Proxmox or Ubuntu, this is a one-time setup. For plug-and-play Linux support, Intel NICs (like on the GMKtec K11) are preferred.
Can I use this for OPNsense/pfSense?
Yes, but with limitations. The single 2.5GbE means you’ll need a USB Ethernet adapter for proper WAN/LAN separation. For dedicated firewall use, the GMKtec K11 with dual Intel NICs is better suited.
Final Verdict
The MINISFORUM AI X1-255 is the best budget AI mini PC with modern connectivity. The 38 TOPS AI compute, WiFi 7, USB4, and upgradeable DDR5 make it the top choice for homelabbers on a budget and users who want future-proof features without paying $1,000+.
At $739, it undercuts the Beelink SER9 by $100 while offering WiFi 7 and upgradeable RAM. The $327 barebone option is exceptional value for DIY builders.
