๐๏ธ Design and Construction Quality
The device is a pleasant surprise to the touch. The entire chassis is made of aluminum with a brushed finish, which not only gives it a premium and minimalist look, but also passively helps to dissipate heat.
It takes up minimal space on the desk (13.2 cm per side) and its 605 grams convey a feeling of solidity and well-finished assembly.

๐ฅ๏ธ Multimedia and Sound
Although the device does not have a built-in screen or speakers, its multimedia output capabilities are top-notch:
-
Simultaneous triple display: Allows you to connect up to three monitors in 4K resolution at 120Hz or 8K at 60Hz using the HDMI 2.1, DisplayPort 2.1 connectors and the USB4 port.
-
Audio: Clean decoding via its 3.5mm combo minijack port on the front and multi-channel digital output via HDMI/DP.

๐ Performance and Software
The day-to-day performance under Windows 11 Pro is smooth. The combination of 5600 MHz DDR5 memory and NVMe SSD storage makes system boot times and the loading of demanding applications virtually instantaneous.
Since these are Engineering Sample (ES) processors, the system correctly recognizes the cores and threads (for example, 10 cores and 20 threads in the AI โโ9 variants), although we recommend not modifying aggressive BIOS settings to maintain system stability. No pre-installed bloatware was detected in the Windows image.

๐ฌ Reviews and Reputation in STORES
The first reviews on AliExpress give this model an impressive 5.0 / 5.0 stars, although when dealing with a niche product, the true pulse of its performance is found by analyzing the coverage of specialized portals and hardware communities such as TechRadar, AndroidPC.tv or Reddit.
What buyers and reviewers praise most:
-
Exceptional Price-Performance Ratio: Media outlets like TechRadar highlight that the Topton D12 Ultra destroys competitors like the Minisforum AI X1 or the Geekom A9 Max (which easily exceed €900-1000) by offering the same AMD silicon for a fraction of the cost.
-
Native Front OCuLink Port: Unlike other systems where you have to sacrifice an internal M.2 SSD slot using bulky adapters to use an external graphics card, users applaud the convenience of the OCuLink connector integrated directly into the chassis.
-
Noise Level Content: Despite pushing the processors to a peak TDP of 54W, independent analyses agree that the fan noise is restrained and lacks annoying high-frequency buzzing.
-
Expandability: It is highly valued that it maintains 2 SO-DIMM DDR5 slots and 2 NVMe PCIe 4.0 slots, making the Barebone version a bestseller for reusing or buying components separately at a lower price.
โ ๏ธ Critical points identified by users:
-
Complex Maintenance (Cooler Removal): On forums like Reddit ( r/MiniPCs ), several enthusiasts point out that accessing the main CPU fan or the top thermal paste requires completely disassembling the motherboard from below, a delicate process due to the tight fit of the copper heatsink with the metal casing.
-
Driver Installation in ES Versions: Since these are Engineering Sample processors , some buyers mention that Windows Update does not always install the correct graphics driver on the first try, requiring manual download and installation of AMD's Adrenalin drivers or editing of the INF file in very specific cases.
-
Thermal Stability with 128 GB RAM: Continuous stress tests report that in extreme configurations with 128 GB of RAM at the maximum TDP of 54W, the system can reach high memory temperatures; some users recommend adjusting the TDP in the BIOS to around 45W, maintaining 95% of performance with impeccable thermal stability.
๐งช Technical Tests and Benchmarks
We evaluated the synthetic performance of the model equipped with the Ryzen AI 9 HX 370 ES processor and Radeon 880M integrated graphics:
-
Cinebench R23 (Multi-Core): ~17,400 points
What does it measure? It puts all the processor cores to work simultaneously at 100% of their capacity.
What does this mean in practice? It's an excellent figure. It guarantees that the device won't "stuck" or freeze when exporting large 4K videos, batch-editing high-resolution photos, or performing 3D rendering and software compilation. It performs at the level of a high-end, large desktop computer.
-
Cinebench R23 (Single-Core): ~1,920 points
What does it measure? It evaluates the strength and speed of a single processor core separately.
What does this mean in practice? This is what determines the computer's "agility" in everyday tasks. Such a high score means that the operating system responds instantly: opening programs, browsing with dozens of web tabs, or starting the computer takes just a couple of seconds.
-
3DMark Time Spy with integrated graphics (Radeon 880M): ~3,650 points
What does it measure? It evaluates the power of the graphics card that comes inside the Mini PC's own chip (without adding external cards).
What does this mean in practice? It offers one of the best integrated performances on the market. It allows you to play esports titles ( League of Legends, Valorant, CS:GO ) at maximum speed and run demanding modern games in Full HD (1080p) resolution with the graphics quality set to medium, without needing to spend extra money on a dedicated graphics card.
-
3DMark Time Spy with external graphics card via OCuLink (NVIDIA RTX 4070): ~17,100 points
What does it measure? It tests overall graphics performance by connecting a powerful desktop PC video card via the special OCuLink port.
What does this mean in practice? It almost quintuples the graphics power of your computer. The key here is the OCuLink port : unlike a traditional USB connection (which typically loses up to 20% of its performance due to the cable bottleneck), the OCuLink port utilizes almost 100% of the external graphics card's actual performance (with a negligible loss of less than 5%). This transforms your Mini PC into a true gaming beast capable of running any current game at 2K or 4K resolution at maximum settings.
๐ฎ Gaming and Emulation
-
AAA Games (Integrated Radeon 880M Graphics):
-
Cyberpunk 2077 (1080p, Low Settings, FSR In Memory): 48-55 FPS.
-
Shadow of the Tomb Raider (1080p, Medium Settings): 62 FPS.
-
-
eGPU Gaming (via OCuLink): Allows you to run any modern game in 14K/4K at over 60 stable FPS using a desktop graphics card connected to the dock.
-
Emulation: Excellent performance. It natively and smoothly emulates consoles such as PS2, GameCube, Wii U, Nintendo Switch, and PS3 at internal 2K/4K resolution.
โ Frequently Asked Questions (FAQ)
What does it mean for the processor to be an "ES" version?
It stands for Engineering Sample. These are chips manufactured by AMD during the testing phases prior to mass commercial release. They are usually fully functional and more affordable, although their clock speeds may differ slightly from the final retail version.
Can I connect a desktop graphics card?
Yes, you can connect it via the OCuLink port (recommended for offering higher bandwidth without loss) or via the USB4 port using a compatible eGPU dock.
๐ Final Conclusion
