🔧 Technical Specifications

🎨 Design and Construction Quality

CHUWI UBox mini PC 

The CHUWI UBox has a square, understated design that fits equally well on an office desk or in a living room next to the TV. The casing combines plastic and metal, with a white/silver or black finish depending on the version. The side and rear ventilation grilles are generously sized—it's clear that CHUWI considered airflow from the design stage.

Weighing in at 650 grams, it's considerably heavier than entry-level mini PCs, but this translates to better heat dissipation and less fan vibration. The front panel features a subtle and elegant status LED. Its 128 × 130.5 × 57 mm dimensions make it perfectly portable—it fits easily into any backpack. The base includes sturdy, non-slip rubber feet, and the VESA mount comes pre-installed for rear-mounting on a monitor.

🖥️ Screen and Multimedia

The CHUWI UBox manages up to three simultaneous monitors thanks to its HDMI 2.0, DisplayPort 1.2 and USB4 outputs:

• 📺 HDMI 2.0: up to 4K@144Hz

• 🖥️ DisplayPort 1.2: hasta 4K@144Hz

• 🔌 USB4: Up to 4K@60Hz (with DP Alt Mode adapter)

4K video playback with hardware decoding is perfectly smooth thanks to the Radeon 660M and its support for AV1 and H.265. For a multi-monitor multimedia or productivity setup, the UBox is an excellent base. It doesn't include speakers, but the 3.5 mm jack is plug-and-play with any external audio system.

⚙️ Performance and Software

The Ryzen 5 6600H (6 cores, 12 threads, Zen 3+ architecture, 6nm process) is a gaming laptop chip that, in this mini PC format, has plenty of room to breathe. In daily use—browsing with 30+ tabs, office applications, 4K streaming, video conferencing—the system is completely fluid without a single lag.

Windows 11 Pro comes clean, with minimal bloatware —only the CHUWI apps for driver updates. Cleaner than the average Chinese mini PC in its price range. The BIOS allows you to configure the VRAM dedicated to the GPU (3 GB by default, expandable to 8 GB), which noticeably improves graphics performance in games [verified review AliExpress]. Users have also confirmed full Linux compatibility —Ubuntu and Mint boot without issues by disabling Secure Boot in the BIOS [verified review AliExpress].

⚠️ Key recommendation: For maximum performance, add a second 16GB DDR5 module to enable dual channel mode — the Radeon 660M benefits greatly from double the memory bandwidth.

📊 Technical Tests

🧠 CPU Performance — Surprisingly Above Its Price

🔍 CPU Conclusion: The Ryzen 5 6600H is a chip that in 2022 powered gaming laptops costing €900-€1,100 — and here it is for €370 in a mini PC form factor. Its ~10,500 points in Cinebench R23 multi-core clearly put it ahead of the Intel N100 (the favorite chip of budget mini PCs, with a mere ~4,000 points) and the previous generation Ryzen 5 5600H. In pure CPU tasks — code compilation, light video editing, intensive multitasking — the UBox performs like a mid-range desktop without any perceptible limitations. The 6nm manufacturing process guarantees real energy efficiency: the chip does a lot of work without significantly increasing power consumption or temperature.

🎮 GPU Performance (Radeon 660M RDNA2) — Capable but with Clear Limits

🔍 GPU Conclusion: The Radeon 660M with 6 RDNA2 Compute Units is a step behind the Radeon 780M in the Ryzen 9 7940HS, but not as far behind as the numbers might suggest. Its ~3,800 points in Fire Strike put it in the territory of a desktop GTX 1050—sufficient for 1080p gaming at low-to-medium settings and for advanced emulation. The critical point is the memory configuration: in single-channel mode (as it comes from the factory), the GPU performs 20-30% worse than in dual-channel. This means that adding a second 16GB DDR5 module is the cheapest and most effective upgrade you can make—for around €35-40 you get a noticeable jump in graphics performance without changing anything else.

🎯 Real Gaming at 1080p — Measured Results

🔍 Gaming Conclusion: The UBox confirms a clear pattern: excellent in esports titles (Valorant, CS2, LoL) where it comfortably exceeds 80-100 fps, and competent in open-world and AAA titles at low settings. The turning point comes with more demanding games like Cyberpunk 2077 or Alan Wake 2, where the Radeon 660M needs FSR to deliver an acceptable experience. The key is to adjust expectations: it's not a machine for playing modern AAA games at ultra settings at a constant 60 fps, but for casual gaming, esports titles, and playing games from 3-5 years ago, it performs surprisingly well.

🕹️ Emulation — The Real Strong Point of the UBox

🔍 Conclusion: For retro emulation, the CHUWI UBox is one of the best value-for-money platforms on the market today. The 6 cores of the Ryzen 5 6600H make a world of difference compared to the quad-core N100/N305 chips that are common in budget mini PCs—especially for emulators that rely on single-core performance (Dolphin, RPCS3). If your main goal is to build an all-in-one retro console with Switch, PS2, GameCube, and classic games, the UBox does it effortlessly and without requiring extensive configurations.

💾 Storage Speed

🔍 SSD Conclusion: The included PCIe 4.0 SSD offers read speeds six times faster than a conventional SATA drive. Windows boots in eight seconds, applications open instantly, and large file transfers are fast. SSD quality varies by manufacturing batch (some users report Micron branding, others generic), but all reviews agree on speeds within the expected PCIe 4.0 range.

⚡ Energy Efficiency

🔍 Efficiency Conclusion: With a maximum consumption of 65-70W under full load, the UBox is radically more efficient than any conventional desktop computer with equivalent performance (which would consume 200-300W). In everyday use, electricity consumption is minimal—in standby mode, it uses less power than an LED light bulb. The 95W power supply has ample headroom for all scenarios, including connected USB peripherals.

🏆 Overall performance rating:

The CHUWI UBox delivers exactly what it promises without any unpleasant surprises. The CPU performs better than expected at €370, the integrated GPU is functional for casual gaming and advanced emulation, and the PCIe 4.0 storage eliminates any bottlenecks in everyday use. The only recommended post-purchase upgrade is adding a second DDR5 module for dual-channel memory—an investment of around €35 ​​that unlocks the full potential of the Radeon 660M and transforms the UBox into a truly complete system.

🎮 Gaming and Emulation

The AMD Radeon 660M (6 CU RDNA2, 1,900 MHz) is a capable integrated GPU, although it doesn't reach the level of the Radeon 780M in the UM790 Pro:

🟢 Gaming 1080p medium/low settings:

• Valorant / CS2: 80-120 fps (very smooth)

• GTA V: 55-60 fps (medium settings)

• Fortnite: ~60 fps (medium quality)

• League of Legends: 100+ fps constantes

• Minecraft (Bedrock): 60+ fps estables

🟡 Gaming 1080p low settings:

• Cyberpunk 2077: ~25-30 fps (requires FSR)

• Elden Ring: ~30 fps (playable with minimum settings)

• FIFA/FC 25: ~45-55 fps

🕹️ Retro emulation — the UBox's strong point:

• PS1 / N64 / GBA: 100% Perfect

• GameCube / Wii (Dolphin): Excelente a 1080p

• PS2 (PCSX2): Almost all games run smoothly

• Nintendo Switch (Ryujinx): Most titles playable at 720-1080p

• PS3 (RPCS3): Works with many titles thanks to its 6 cores

One AliExpress buyer describes it as "a great machine for creating a retro gaming experience" —and the data backs that up. For emulation, the UBox offers exceptional value for money.
