Dimension Scores
The AMD Ryzen 7 8845HS processor with 8 cores, 16 threads, and a boost clock up to 5.1GHz, plus a dedicated NPU, delivers top-tier performance for a mini PC.
With 32GB DDR5 RAM expandable to 96GB/128GB, a 1TB PCIe 4.0 M.2 SSD with dual slots for up to 8TB, and an Oculink port for external GPU upgrades, this mini PC offers extensive expansion options.
Users report CPU/GPU temperatures reaching over 90°C under load and persistent fan noise, even in sleep mode, indicating thermal management and acoustics are below average for a premium device.
While featuring a machined aluminum chassis, the transparent twist-off top is noted as looking cheap, and some units exhibit issues like random BSODs or faulty Bluetooth, suggesting inconsistent quality control.
Best For
- Gamers who want to play less demanding titles at 1080p or are planning to use an external GPU via Oculink.
- Content creators needing a compact machine for video editing and multitasking, leveraging the 8-core/16-thread processor.
- Users requiring extensive connectivity with dual 2.5Gbps LAN, multiple 4K/8K display outputs, and USB4 ports.
- Anyone looking for a small form factor PC that can handle local AI tasks with its dedicated NPU.
Not Recommended For
- Users who need a completely silent PC, as fan noise, even in sleep mode, has been reported.
- Those who expect to play demanding AAA games at high settings without an external GPU, as the integrated Radeon 780M has limitations.
- Buyers prioritizing top-tier customer service, given reports of slow or absent support responses.
Watch Out For
- The Bluetooth adapter can fail to start with a 'Code 10' error after shutdown, requiring a manual disable/enable in Device Manager.
- Fan noise can be a mechanical grinding or high-pitched sound, not just airflow, and persists even in sleep mode for some units.
- CPU and GPU temperatures can hit over 90°C during stress tests, potentially due to factory thermal paste application.
- Some units experience random Blue Screens of Death (BSODs) and restarts shortly after initial setup, even after reseating RAM and SSD.
- Wi-Fi connectivity can be inconsistent, with some users reporting issues or weak performance from the Wi-Fi card.

What Buyers Say
The most surprising finding is the recurring Bluetooth connectivity issues, where the device fails to start after shutdown, forcing users to manually re-enable it. Many users also struggle with fan noise, describing it as a mechanical grinding or high-pitched sound that can be present even when the PC is idle or in sleep mode. While the AMD Ryzen 7 8845HS processor and Radeon 780M integrated graphics deliver strong performance for its size, thermal management under heavy loads can be a concern, with temperatures frequently hitting above 90°C. Customer support from GMKtec is frequently criticized for being unresponsive, leaving users to troubleshoot issues like random BSODs or Wi-Fi problems on their own.
“I bought this thing for the Oculink and the 8845HS, and yeah, it flies for what I need, but seriously, the Bluetooth is a headache every single time I boot up, and the fan noise is just… there. It's like a tiny jet engine sometimes. I wish support would actually answer!”
Common Praise
- The AMD Ryzen 7 8845HS processor delivers serious power for multitasking and video editing.
- The integrated Radeon 780M GPU handles 1080p gaming in less demanding titles without a hitch.
- The Oculink port is a game-changer for future external GPU upgrades and faster storage.
- Connectivity is stacked with dual 2.5Gbps LAN, WiFi 6, Bluetooth 5.2, and multiple 4K/8K display outputs.
- Its compact size and VESA mount compatibility make it easy to integrate into any setup.
- The NPU for AI workloads is a forward-looking feature for local AI tasks.
Common Complaints
- Bluetooth constantly disappears after shutdown, showing a 'Code 10' error in Device Manager.
- The fan makes an annoying grinding or high-pitched noise, even when the PC is supposed to be quiet.
- CPU and GPU temperatures spike above 90°C during gaming or stress tests, suggesting inadequate thermal paste or cooling.
- Customer support is basically non-existent, with users waiting weeks for replies or getting no response at all.
- Some units experience random Blue Screens of Death and unexpected restarts, even with fresh Windows installs.
- The fan sometimes runs continuously even when the PC is in sleep mode, preventing true low-power states.
Ownership Tips
- The Bluetooth issue often requires manually disabling and re-enabling the device in Windows Device Manager after every shutdown.
- Replacing the factory thermal paste with a higher-quality compound can significantly reduce CPU/GPU temperatures under load.
- Some users have attempted physical modifications, like adding spacers to the RAM, to mitigate fan grinding noises.
- The fan running in sleep mode means it's not truly silent when 'off,' which can be disruptive in quiet environments.
- Despite the powerful specs, consistent Wi-Fi issues have been reported, potentially requiring driver updates or a replacement card.

Buying Guide
When you're looking at a mini PC like this, you need to think about what you're actually going to do with it. Don't just get caught up in the raw specs. For gaming, an integrated GPU has limits, so if you're a hardcore gamer, you'll need to factor in the Oculink port for an external GPU. Also, consider where it's going to sit; if it's right next to you, fan noise and heat are going to be a bigger deal than if it's tucked away behind a monitor.
AMD Ryzen 7 8845HS Processor
This is the brain of the PC. The 'HS' means it's a high-performance chip designed for laptops and mini PCs, balancing power with efficiency. The 8 cores and 16 threads mean it can handle many tasks at once, like editing video while browsing, without slowing down. Think of it like a multi-lane highway for your data.
AMD Radeon 780M Integrated GPU
This is your graphics card, but it's built right into the processor. It's not a dedicated, separate card, so it won't run the newest, most graphically intense games at max settings. However, for older games, esports titles, or creative work that benefits from GPU acceleration, it's surprisingly capable for an integrated solution. It's like having a really good built-in graphics chip, not a monster gaming card.
Oculink Interface
This is a special port that lets you connect external devices, particularly external graphics cards (eGPUs), at very high speeds. If you buy this mini PC now and want to upgrade your gaming performance significantly later, this port is your ticket to adding a powerful desktop graphics card without needing a whole new system. It's like having a secret turbocharger port for future upgrades.
Dual 2.5Gbps Ethernet
Most computers have one standard (1Gbps) Ethernet port. This mini PC has two, and they're 2.5 times faster. This is overkill for most home internet, but if you have a super-fast network, a network-attached storage (NAS) device, or want to run a home server, these ports give you serious bandwidth. It's like having two express lanes on your network instead of one regular lane.
Alternatives
If you need a completely silent operation, look for mini PCs with passive cooling or larger chassis designs that can accommodate bigger, slower fans. For guaranteed top-tier gaming performance, search for mini PCs that include a dedicated mobile GPU or have Thunderbolt 4 ports for wider eGPU compatibility.
