Review of the PELADN WO4 mini PC with Ryzen 5 7640HS

The PELADN WO4 with Ryzen 5 7640HS is one of the most complete mini PCs in its price range in 2026.

Zen 4 4nm architecture, 32GB of dual-channel DDR5, support for four simultaneous displays, and a magnetic cover that makes upgrades easier than any other.

If you're looking for a mini PC for advanced productivity, 4K video editing, emulation, and light gaming without spending more than €550, this is a serious contender.

✅ Pros

• Zen 4 (7640HS) processor with turbo up to 5.0 GHz — one of the most powerful APUs in a mini PC

📋 Complete Technical Specifications

🎨 Design and Construction Quality

PELADN WO4 Mini PC 

The PELADN WO4 retains the same compact 128×128×52 mm chassis as the 5600H version, but what visually sets it apart from the competition is its magnetic top cover. It can be removed with one hand in under two seconds, without screwdrivers or clips to break. For any user looking to upgrade RAM or add a second SSD, it's a real game-changer.

The build quality is solid, with a high-density plastic finish and a matte texture that doesn't show fingerprints. The side and rear ventilation grilles are generous, indicating that the thermal design was carefully considered for the 7640HS's 45W TDP. Despite its size, the unit doesn't vibrate or squeak when running. It fits comfortably in the palm of your hand and mounts securely behind any monitor thanks to the included VESA mount.

🖥️ Screen and Multimedia

One of the most striking features of this model is its support for four simultaneous screens, something uncommon even in more expensive mini PCs.

The available exits are:

• HDMI 2.0 — up to 4K@60Hz

• DisplayPort 1.4 — up to 4K@60Hz

• USB4 Type-C — up to 4K@60Hz with DP 1.4 and 40Gbps data transfer

• USB 3.2 Type-C — compatible with DP 1.2 output

For multimedia content, the Ryzen 5 7640HS supports hardware decoding of H.264, H.265, and AV1, meaning that 4K video playback, whether streaming or locally, is completely smooth without putting a strain on the CPU. The 3.5 mm audio jack works for both headphones and microphones. It does not include internal speakers, as is typical in this category.

🚀 Performance and Software

The Ryzen 5 7640HS, with its 4nm Zen 4 architecture, represents a generational leap compared to Zen 3 chips like the 5600H. In everyday use—browsing, office applications, document editing, video conferencing—the system responds instantly thanks to the combination of dual-channel DDR5 5600 MHz memory and a 5.0 GHz turbo boost.

Benchmarks (based on independent reviews):

💡 The score of 2,800 in Time Spy is practically double that of a Steam Deck, which gives an idea of ​​the real graphical performance.

Software and operating system: Windows 11 Pro comes pre-installed and ready to use. In review tests, boot time is around 8-10 seconds. The system arrives virtually free of bloatware, with only the PELADN and AMD drivers pre-installed. Windows updates arrive without issues, and the computer is fully compatible with Linux Ubuntu without any additional configuration.

🔋 Energy Consumption and Cables

The PELADN WO4 7640HS has a TDP set to 45W by default, although the actual power consumption at the wall during a full stress test can reach 75W in the first few minutes before stabilizing at around 62W.

The included power adapter is 90W, sufficient for all scenarios. The USB Type-C port also accepts PD charging, allowing you to power the device with a compatible external USB-C charger—very useful for compact setups or behind-the-monitor mounting.

🌡️ Temperature and Noise (Actual Thermal)

Under sustained load, the Ryzen 5 7640HS reached peak temperatures of 91°C during the first two minutes of the stress test, gradually dropping and stabilizing around 82°C. These temperatures are normal and expected for a 45W APU in a 128x128mm chassis and do not affect performance thanks to AMD's intelligent throttling system.

As for noise, the fan is virtually inaudible during office tasks and browsing. Under sustained load, a soft, constant hum is audible—nothing bothersome in a normal work environment. Reddit users who have tested the device describe it as "running cool" in daily use, praising the magnetic lid as an element that also improves internal airflow.

🔌 Connectivity and Extras

Connectivity is one of the strengths of this model compared to its direct competitors:

⚠️ Area for improvement: There are no USB 3.x ports on the back — both fast USB ports are on the front. This could be a minor inconvenience for VESA mounts behind the monitor.

🔧 Expansion and Upgrades

The magnetic lid makes opening the PELADN WO4 surprisingly easy. Once inside, you have direct access to all expandable components:

• RAM: 2 SO-DIMM DDR5 slots. Comes with 2 x 16 GB. Expandable up to 64 GB (2 x 32 GB). Important: DDR5 only, not compatible with DDR4.

• Primary SSD (PCIe 3.0 slot): Already occupied by the included 1 TB drive. You can replace it with a larger one (up to 4 TB).

• Second M.2 slot (free PCIe 4.0): Completely free for a second high-speed SSD — up to 4 TB. This is the slot where you should install a PCIe 4.0 SSD to take advantage of the bandwidth.

• 2.5" SATA Bay: Free to add a 2.5" HDD or SSD — up to 2 TB. SATA cable included in the box.

• GPU VRAM: Adjustable from BIOS up to 4 GB allocated to the Radeon 760M — highly recommended to enable for gaming and editing.

  💡 Upgrade tip: Install an NVMe PCIe 4.0 SSD in the second slot for high-performance storage, and leave the system's PCIe 3.0 slot for the operating system.

🆚 Comparison with Direct Competitors

The PELADN WO4 7640HS stands out as the only one in its range with support for four displays, a magnetic lid, and 32GB of DDR5 RAM as standard. The GMKtec M6 Ultra comes with a PCIe 4.0 SSD, offering a storage speed advantage at the same price.

🧪 Technical Tests

CPU performance

The 7640HS in 45W mode keeps its cores running smoothly without aggressive throttling — a key difference compared to laptop chips that drop to 15-25W under load.

GPU performance (Radeon 760M)

With 4GB of VRAM allocated from the BIOS, the Radeon 760M significantly improves performance in gaming and AI/editing tasks compared to the default 2GB configuration.

Storage

🎮 Gaming and Emulation

The Radeon 760M with RDNA 3 is the most capable integrated GPU in the range at this price point. With the VRAM set to 4GB in the BIOS, gaming performance is noticeably improved.

Gaming performance (1080p, medium-low quality):

Emulation:

🎮 For retro emulation up to PS2/GameCube, the PELADN WO4 7640HS is an excellent option. For Switch and PS3, the results are acceptable but not perfect.

❓ Frequently Asked Questions (FAQ)

Can I use this mini PC with Linux? Yes. It's fully compatible with Ubuntu and other Linux distributions without any special configuration. Several users have used it in a dual-boot configuration with Windows and Linux without any issues.

Is the included SSD PCIe 3.0 or 4.0? The pre-installed 1TB SSD is in the PCIe 3.0 slot. However, there is a second free M.2 PCIe 4.0 slot where you can install a faster SSD.

Can I upgrade the VRAM on the Radeon 760M? Yes. You can allocate up to 4GB of VRAM to the GPU from the BIOS, which improves performance in gaming, 4K editing, and AI tasks. It's highly recommended to do this after the initial setup.

How does the PELADN WO4 with Ryzen 5 5600H differ? The 7640HS uses Zen 4 (4nm) architecture, while the 5600H uses Zen 3 (7nm). The Radeon 760M GPU is 130% faster than the Vega 7, and DDR5 support increases memory bandwidth. Furthermore, this model supports four displays compared to the 5600H's three.

What's the difference between the 16GB and 32GB versions? The 32GB version comes with 2 x 16GB in dual channel, taking full advantage of the Radeon 760M's maximum bandwidth. The 16GB version may come in single-channel configuration, which reduces graphics performance by up to 30-40%.

Does it include Windows 11 Pro? Yes, the full version includes Windows 11 Pro pre-installed and activated.

🏁 Final Conclusion

The PELADN WO4 Ryzen 5 7640HS is a mini PC that delivers exactly what it promises: next-generation performance in an ultra-compact format and at a competitive price.

It is ideal for:
