🎨 Design and Construction Quality

Premium Quality Floating Metal Frame

The GMKtec M8 features a  sleek, industrial design with a floating metal frame  reminiscent of the more expensive EVO-X1 from the same brand. The build quality is solid and premium to the touch, with aluminum finishes that not only look professional but also aid in heat dissipation.

The ultra-compact chassis virtually disappears into any desktop setup, taking up less space than a paperback book. The materials inspire confidence:  there's no flexing, creaking, or feeling of fragility  that other budget mini PCs often have.

Intelligent Port Distribution

Front Panel:  OCuLink, USB4, 2x USB 3.2 Type-A, 3.5mm jack, CMOS reset button, and power button. This layout allows for quick access without needing to constantly rotate the device.

Rear Panel:  Dual 2.5GbE LAN ports, HDMI 2.1, USB-C with DisplayPort, additional USB ports, and power input. The design prioritizes professional connectivity without sacrificing accessibility.

Ventilation and Cooling

The cooling system includes  active fans that maintain controlled temperatures  under most workloads. Reviewers report stable temperatures during extended use, although the fan becomes audible during intensive tasks such as rendering or gaming. The stock thermal paste is functional, but advanced users can improve temperatures by replacing it with Arctic MX-6.

🖥️ Screen and Multimedia Capabilities

8K Triple Display Support

The GMKtec M8  promises support for three simultaneous displays with resolutions up to 8K . In real-world tests with 4K displays, performance was solid and without any display issues. The combination of HDMI 2.1, USB-C with DisplayPort, and the ability to use OCuLink for additional output via an external GPU offers exceptional flexibility.

Multimedia Performance

Video Playback:  YouTube 4K plays without stuttering or dropped frames. The Radeon 660M GPU handles modern codecs including AV1, HEVC, and VP9 with hardware acceleration.

Audio:  The combined 3.5mm jack delivers clear audio for headphones and external speakers. It does not have built-in speakers (common in mini PCs of this category).

Streaming:  Perfect for services like Netflix, Amazon Prime, and Disney+ in 4K HDR thanks to hardware-accelerated decoding.

⚡ Performance and Software

Power of the Ryzen 5 Pro 6650H

The AMD Ryzen 5 Pro 6650H processor with  6 Zen 3+ cores and 12 threads, reaching a boost clock of 4.5GHz,  delivers surprising performance for its size. In the real world, this translates to  instant responsiveness : applications open instantly with a click, multitasking feels smooth rather than choppy, and working with multiple browser tabs and demanding applications simultaneously is effortless.

Real Benchmarks

Geekbench 5:

• Single-Core: ~1,450 points

• Multi-Core: ~7,800-8,200 points

3DMark Fire Strike Ultra:  Approximately 878 points

3DMark Solar Bay Extreme:  ~878 points

NVMe SSD Speed:

• Sequential read: ~1,159 MB/s

• Average write speed: ~267 MB/s

• Minimum write speed: ~90 MB/s during gaming

Gaming Performance (Integrated GPU)

The  AMD Radeon 660M  is capable but has clear limitations:

✅ Games that run well (1080p, medium-high settings):

• Hammerwatch

• Dave the Diver

• Rocket League

• Counter-Strike 2 (medium settings)

• Fortnite (competitive settings)​

⚠️ Demanding games require low settings or eGPU:

• Cyberpunk 2077: Playable but requires minor adjustments

• Indiana Jones and the Great Circle: Stuttering noticeably, needs to lower settings.

• Hogwarts Legacy: Playable with reduced settings but experiences microstuttering.

Gaming Verdict:  Without an external GPU, this machine handles  casual gaming and esports without problems , but for modern AAA titles you'll need to connect an eGPU via OCuLink.

OCuLink: The Game-Changer

The  OCuLink port unlocks the true gaming potential  of the M8. Unlike USB4, which has limited bandwidth and overhead, OCuLink provides  a direct PCIe connection for external GPUs without significant bottlenecks . Users report playing AAA titles in 4K ultrawide without issues when connecting high-end GPUs.

Software and Windows 11 Pro

Windows 11 Pro comes pre-installed and activated . Reviewers note that the system is relatively clean, without excessive bloatware. Some users recommend running debloat scripts to further optimize performance.

System stability is excellent :  no blue screens, no unexpected restarts, and no reported compatibility issues. The BIOS receives regular updates that fix minor problems, such as an initial bug with the eGPU that GMKtec quickly resolved.

🔌 Connectivity and Extras

Professional-Level Connectivity

Dual 2.5 Gigabit Ethernet LAN:  A standout feature for home lab users  , virtualization, NAS servers, and firewalls . It allows for advanced network configurations, failover, link aggregation, or simply traffic separation.

WiFi 6E:  Next-generation wireless technology with support for the 6GHz band, delivering consistent speeds without drops. Tests show stable performance on both 2.4GHz and 5GHz.

USB4 (40Gbps):  Allows you to connect high-performance docks, ultra-fast storage, or even external GPUs (although OCuLink is superior for eGPUs).

Bluetooth 5.2:  Stable connection for wireless peripherals.

• Mini PCs with comparable specifications cost around $500+

Possible Alternatives

If integrated gaming is your priority:  Beelink SER8 (Ryzen 7 8845HS) with a more powerful GPU, but more expensive.

If you need more RAM:  Minisforum UM790 Pro (up to 64GB expandable), higher price

If you're looking for greater portability:  Intel NUC 13 Pro (more compact), but with less connectivity.

If absolute silence is your priority:  GEEKOM Mini IT13 (fanless design), lower performance

Final Verdict: ⭐⭐⭐⭐½ (4.5/5)
