Design & Build – Compact, Sturdy, and Thoughtfully Engineered
The E3B sports a minimalist matte-black finish and a premium metal-plastic blend chassis that feels reassuringly solid. It’s roughly the size of a stack of coasters — compact enough to fit behind your monitor or mount to the back of a display using its VESA bracket. The front ports are easily accessible, the power button is tactile, and the LED indicator gives it a subtle glow when in operation.
Despite its miniature footprint, this machine feels engineered with care. The internal cooling design features a low-noise fan and precision air vents that keep temperatures in check even under sustained workloads. Whether you’re running multiple applications or playing lighter esports titles, the E3B remains whisper-quiet — a major plus if you work in quiet spaces or shared offices.
Performance – Ryzen 7 Efficiency Meets Everyday Power
At the heart of the E3B lies the AMD Ryzen 7 7730U processor — an 8-core, 16-thread chip capable of boosting up to 4.5GHz. It comfortably outperforms the older Ryzen 7 5825U, offering improved single-thread responsiveness and better power efficiency.
For general computing, it’s lightning fast: boot times are near-instant, apps open quickly, and multitasking feels fluid. You can easily juggle dozens of browser tabs, spreadsheets, streaming sessions, and editing tasks without slowdown.
In creative workloads like photo editing or video trimming, the Ryzen 7 and integrated Radeon Vega graphics deliver enough muscle for smooth playback and quick render times. While it’s not designed for high-end AAA gaming, titles like Valorant, CS:GO, League of Legends, and Minecraft run comfortably at 1080p with moderate settings.
For office tasks, productivity, and light content creation, the E3B feels far more capable than its size suggests.
Cooling & Noise – Silent and Efficient
Mini PCs often struggle with heat, but KAMRUI nailed the balance here. The E3B’s internal layout allows efficient airflow, with the cooling fan intelligently adjusting speed based on thermal load. During typical workloads, the fan operates quietly enough to be nearly inaudible; even during heavier tasks, it remains a soft hum rather than a distraction.
This excellent thermal performance ensures the CPU maintains high boost speeds without throttling, extending both performance and longevity.
Memory & Storage – Speed with Flexibility
The included 16GB DDR4 RAM provides plenty of bandwidth for multitasking and smooth application switching. The 512GB NVMe SSD offers fast read/write speeds, making boot times and program launches instantaneous. For those who need more space, the E3B supports easy expansion via an additional M.2 slot or 2.5″ SATA drive, allowing storage upgrades up to several terabytes.
This upgradability is one of its hidden strengths — something that many compact PCs lack.
Connectivity & Ports – Built for Versatility
The KAMRUI E3B is impressively equipped when it comes to connectivity. It supports Wi-Fi 6 and Bluetooth 5.2, ensuring high-speed wireless connections and stable performance for peripherals and streaming.
Port selection is generous:
- 2 × HDMI (up to 4K@60Hz)
- 1 × DisplayPort
- 4 × USB-A (3.2 Gen 1/2)
- 1 × USB-C (data and display support on select versions)
- Gigabit Ethernet port
- 3.5mm audio jack
This setup supports triple-monitor output, making it perfect for professionals who multitask or gamers who prefer immersive setups. Whether you’re connecting an ultrawide monitor or three 4K panels, the integrated Radeon graphics handle multiple displays smoothly.
Everyday Experience – Quiet Power That Adapts
The KAMRUI E3B excels in adaptability. In a home office, it feels fast and responsive for everything from document creation to conference calls. As a living-room media center, it’s powerful enough to stream 4K HDR content with no lag or buffering. For students, developers, and professionals, its compact design and capable hardware make it ideal for dorm desks, studio setups, or tight workspaces.
You can also repurpose it as a home server, NAS controller, or HTPC, thanks to its low power draw and stable performance.
Gaming & Graphics – Light Gaming, Smooth Entertainment
While not a full gaming powerhouse, the integrated Radeon Vega 8 graphics allow enjoyable gameplay for popular titles at 1080p medium settings. Games like Fortnite, DOTA 2, Genshin Impact, and Rocket League run smoothly, especially if paired with dual-channel RAM for improved bandwidth.
It’s also excellent for retro gaming and emulation — PlayStation 2, Wii, and even some PS3 emulators perform respectably when configured properly.
For casual gaming, streaming, or cloud-based services like Xbox Cloud Gaming or GeForce NOW, the E3B delivers a balanced experience with minimal input lag.
Productivity & Multitasking – Small Size, Big Impact
The E3B is a multitasking champ. With 8 cores and 16 threads, you can comfortably run complex workloads such as running virtual machines, using OBS for streaming, or editing large spreadsheets. It also handles light video production without breaking a sweat.
Office users will appreciate its ability to stay responsive while running multiple productivity apps — Microsoft Office, Slack, Chrome, and Zoom all perform flawlessly together.
