MINISFORUM AI X1-255
Published on
The MINISFORUM AI X1-255 is a compact desktop replacement built around AMD's 8-core, 16-thread Ryzen 7 255 with Radeon 780M graphics, wrapped in a silver aluminum chassis that measures roughly five inches square. It leans on current connectivity: WiFi 7, Bluetooth 5.4, two USB4 ports, and a rear OCuLink port that opens the door to an external GPU. That port array can drive up to four displays through HDMI 2.1, DisplayPort 2.0, and the two USB4 connectors, while both the DDR5 memory and the pair of M.2 slots stay user-serviceable. Built-in dual speakers and a microphone make it usable straight out of the box without extra peripherals. MINISFORUM also sells a similar-sounding X1 Lite-255 (WiFi 6E, no built-in speakers) and a higher-end Zen 5 AI X1 Pro, so it pays to confirm the exact model before buying.
Pros and Cons of the MINISFORUM AI X1-255
| Pros | Cons |
|---|---|
| 8-core Zen 4 Ryzen 7 255 with Radeon 780M handles multitasking and 1080p gaming | The "AI" name oversells it: the Ryzen 7 255 is a rebadged 2024 Hawk Point chip with a modest NPU |
| WiFi 7 and Bluetooth 5.4 bring current wireless standards | The rear OCuLink shares a PCIe lane with the second M.2 slot, so an eGPU costs a storage slot |
| Two USB4 (40Gbps) ports plus a rear OCuLink for external-GPU expansion | Single 2.5GbE LAN, where the AI X1 Pro offers dual ports |
| Drives up to four displays via HDMI 2.1, DP 2.0, and dual USB4 | Bluetooth range is weak, dropping past a few meters in one reviewer's test |
| Quiet, efficient cooling that stays stable under sustained load | DisplayPort output is native only and does not convert to HDMI, per one buyer |
| User-upgradeable: 2x DDR5 SO-DIMM (up to 64GB) and 2x M.2 PCIe 4.0 | Radeon 780M is capable but aging, and no substitute for a discrete GPU in demanding games |

Detailed Insights into the MINISFORUM AI X1-255
The AI X1-255 keeps a small footprint, measuring about 128 by 126 by 52 millimeters (roughly 5.04 by 4.96 by 2.05 inches) in a high-grade aluminum-alloy chassis with mesh venting along the sides. The front face is where you plug in day to day: two USB-A 3.2 Gen 2 ports at 10Gbps, one USB4 Type-C port, a 3.5mm combo audio jack, dual microphones, and a power button with an LED. The rear carries the DC barrel jack, a second USB4 port, a single 2.5 Gigabit Ethernet jack, HDMI 2.1, DisplayPort 2.0, a USB 2.0 Type-A port, and the OCuLink connector. It is an unusually complete rear panel for a machine this size, though the lone USB 2.0 port is a legacy inclusion better suited to a keyboard or mouse than fast storage.
The Ryzen 7 255 is an 8-core, 16-thread Zen 4 part (AMD's Hawk Point family, a rebadge of the Ryzen 7 8745HS) that boosts to 4.9GHz and configures up to a 65W TDP in this chassis. It lands around 28,700 on PassMark's CPU benchmark, which is strong for productivity, video calls, and code compiles, but it is a generation behind AMD's Zen 5 Ryzen AI silicon and carries only a small NPU, so the "AI" in the name is more marketing than muscle for on-device AI work. MINISFORUM's own materials put it near 15,600 in Cinebench R23 multi-core and 1,724 single-core; treat those as vendor figures rather than measured results. The integrated Radeon 780M (12 compute units) is the same class of graphics found across this generation of AMD mini PCs, capable at 1080p and low-to-medium settings but not a gaming GPU on its own.
Where the AI X1-255 earns its keep is expansion and connectivity. Two SO-DIMM slots take up to 64GB of DDR5-5600, and two M.2 2280 slots run PCIe 4.0 for up to 4TB each. The rear OCuLink port (PCIe 4.0 x4) is the standout: it lets you bolt on an external GPU with more bandwidth than USB4 or Thunderbolt can offer, which is the real path to serious gaming here. The catch is that enabling OCuLink borrows a PCIe lane from the second M.2 slot, so heavy storage and an eGPU compete for the same resource. Our guide to mini PC eGPU connectors breaks down how much performance each port type preserves. Wireless is handled by WiFi 7 and Bluetooth 5.4, with a single 2.5GbE port for wired networking.
Reviewer Insights on the MINISFORUM AI X1-255
NotebookCheck
NotebookCheck frames the machine around its processor, writing that "the focus is on the new AMD Ryzen 7 255, which makes the AI X1 an exciting candidate for work environments, multimedia, and light gaming." Their testing emphasized composure under pressure: "even under continuous load, the system remains surprisingly stable, both in terms of temperature and noise." For daily work they found that "in everyday use, the AI X1 proves to be a responsive system that starts programs quickly and hardly breaks a sweat when using several applications in parallel." Their overall read was positive, concluding that "with the AI X1, Minisforum delivers a versatile mini PC that packs modern technology into a small case and impresses above all with its efficiency, features, and practical performance." The main limitation they flagged was the ceiling of integrated graphics, which do not reach the level of a dedicated GPU without external hardware.
Family Pop TV
Family Pop TV reviewed a 64GB/1TB configuration hands-on, with a teardown, thermal-camera readings, and noise measurements. On processor and graphics performance the reviewer said, "this thing punches above its weight... rendering in 4K is where the Radeon 780M really shows up." The OCuLink path drew the most enthusiasm: "with the eGPU connected via Oculink, Forza Horizon 5 is now flying at high setting, 138 to around 170 FPS. No drama, smooth and sharp." Their measurements showed quiet, cool operation (exhaust temperatures peaking in the mid-40s Celsius, and noise around 32 decibels at idle rising to roughly 40 decibels under load) and identified name-brand internals like a Kingston NVMe SSD. Not everything impressed, though: the reviewer flagged the wireless range, noting that "Bluetooth range could use some gym time. Anything over 3m and your controller might start ghosting."
Across both sources the pattern is consistent. Reviewers praise the efficiency, quiet cooling, and the flexibility that USB4 and OCuLink bring, while the recurring caveat is that the integrated Radeon 780M needs an external GPU to reach beyond light gaming.
Conclusion
The MINISFORUM AI X1-255 is a strong pick for someone who wants a quiet, compact desktop replacement with genuine room to grow. The 8-core Ryzen 7 255 is more than enough for office work, browsing, video calls, and light content creation, and the combination of WiFi 7, dual USB4, four-display output, and a rear OCuLink port gives it flexibility that most mini PCs at this size lack. The user-upgradeable DDR5 and dual PCIe 4.0 slots mean you can start small and add memory or storage later, and the built-in speakers make it usable the moment you plug in a display.
Weigh the trade-offs first. The Ryzen 7 255 is a rebadged 2024 Zen 4 chip, so buyers chasing the newest silicon or a real on-device AI NPU should look at Zen 5 Ryzen AI systems instead. Using the OCuLink port for an external GPU costs one of the two M.2 storage slots, the machine has only a single 2.5GbE LAN port, and the Radeon 780M is capable but no longer cutting-edge. If you want the same eGPU flexibility with a flagship processor, MINISFORUM's AI X1 Pro steps up to the Zen 5 Ryzen AI 9 HX 370.

Frequently Asked Questions
What processor does the MINISFORUM AI X1-255 use?
The AI X1-255 uses the AMD Ryzen 7 255, an 8-core, 16-thread Zen 4 processor (a rebadge of the Ryzen 7 8745HS from AMD's Hawk Point family) with a base clock of 3.8GHz and boost up to 4.9GHz. It integrates Radeon 780M graphics and scores roughly 28,700 on PassMark's CPU benchmark, which is well suited to productivity, browsing, and light gaming.
Can I upgrade the RAM and storage in the AI X1-255?
Yes. The AI X1-255 has two DDR5 SO-DIMM slots that accept up to 64GB of DDR5-5600 memory, and two M.2 2280 slots running at PCIe 4.0 that support up to 4TB per slot. Both memory and storage are user-serviceable, though the barebone version ships with neither RAM nor an SSD so you can supply your own.
What is the OCuLink port for on the AI X1-255?
The rear OCuLink port runs at PCIe 4.0 x4 speeds, letting you connect an external GPU enclosure with more bandwidth than USB4 or Thunderbolt. This is the practical way to add desktop-class graphics performance. Note that using OCuLink borrows a PCIe lane from the second M.2 slot, so an external GPU and a second SSD share the same resource.
How many displays can the AI X1-255 drive?
The AI X1-255 can output to up to four displays at once, using its HDMI 2.1 port, DisplayPort 2.0 port, and two USB4 ports with DisplayPort Alt Mode. HDMI and DisplayPort both support up to 8K at 60Hz, making it capable for multi-monitor productivity setups.
Does the AI X1-255 have a real AI NPU?
Despite the "AI" branding, the Ryzen 7 255 is a rebadged 2024-era Zen 4 chip with only a modest NPU, far short of the 50 TOPS on newer Ryzen AI parts like the HX 370 in the AI X1 Pro. If on-device AI acceleration is your priority, a Zen 5 Ryzen AI system is a better fit; the AI X1-255 is better understood as a capable general-purpose mini PC.
How is the AI X1-255 different from the X1 Lite-255 and AI X1 Pro?
All three share the Ryzen 7 255 family branding, but they are different machines. The AI X1-255 has WiFi 7, Bluetooth 5.4, built-in speakers, and a native rear OCuLink port. The X1 Lite-255 uses WiFi 6E, Bluetooth 5.2, and an included M.2-to-OCuLink adapter instead. The AI X1 Pro is a larger, higher-end machine with the Zen 5 Ryzen AI 9 HX 370, dual 2.5GbE LAN, and three M.2 slots.
What comes in the box with the MINISFORUM AI X1-255?
The AI X1-255 ships with the mini PC, a 120W power adapter, an HDMI cable, a VESA mounting bracket with screws, and a quick start guide. Configured versions add the RAM and SSD listed for that model, while the barebone version leaves memory, storage, and the operating system for you to install.
