KAMRUI E3B Mini PC REVIEW Compact Performance for Everyday Productivity ...Middle East

A Ryzen-powered mini PC that delivers stable performance, quiet operation, and reliable multitasking in a space-saving design built for work and light creative use.

I’ve been a “work from home” person since 2020. Even though remote work is now built into a lot of industries, working from the comfort of my own home still feels like a luxury. One of the biggest challenges with working from home is figuring out the right equipment. Fortunately, the Mini PC market is more advanced that it has ever been. With a Mini PC, you have a lot of power in a much smaller footprint. These tiny computers have transitioned from a niche category into something that is genuinely practical for everyday use.

Before reviewing them for MacSources, my experience with these little wonders was limited to Mac minis, but as modern processors have become more and more efficient, smaller systems are more capable of handling real workloads. The Mini PC I have most recently become acquainted with is the KAMRUI E3B Mini PC. It’s built around the AMD Ryzen V2748 chip and features 8 cores, 16 threads, and boost speeds up to 4.3GHz, paired with integrated Radeon Vega graphics for handling everyday tasks and light creative workloads.

Unboxing & Setup

The KAMRUI E3B Mini PC came in a simple white cube box with the words “Pinova Series” and “Mini PC” stamped on it. It’s a nondescript box and doesn’t have any imagery on it. The back has some very basic details included and indicates exactly which model is in the box. There are checkboxes for the different components that are included with that specific model (color, RAM, ROM, etc). It’s obvious that the same box is used for multiple versions of the PC. It comes with a VESA compatible mount, an HDMI cable, and the power adapter.

Out of the box it was very easy to setup. I plugged in the power cable, HDMI cable, a USB-C cable (Keyboard), and a USB-A cable (Mouse). Then I powered it on. It immediately took me through the standard Windows setup. The keyboard and mouse worked without any need for special drivers and I was able to use them throughout the setup. During the setup process, the Mini PC went through a series of standard Windows updates that took approximately 30 minutes. During the updates, the fan of the PC kicked on.

Once the updates were done, I logged in with my Microsoft account and set a pin number for the Mini PC. Then, I set it up as a new PC. I always do this when I’m testing PCs so that it is the cleanest possible version of itself when I run benchmark tests.

Testing

Because I wanted to give the E3B a well-rounded evaluation, I ran it through a series of tests we use to measure the performance of a PC. These tests included:

When you pair these tests with the User Impressions section (below), users are given a clear picture of what the system is really like and how well it will work for given tasks. The results of each of the tests are listed below.

Geekbench CPU Scores

Interpretation: The single-core score is right in line with what you’d expect from this processor, showing strong responsiveness for everyday tasks like browsing and office work. The multi-core score falls within the expected range, indicating the CPU is performing properly under load without any signs of throttling. The GPU/Open CL is a typical result for integrated Radeon Vega graphics, confirming it can handle light graphics workloads but isn’t built for heavy GPU tasks. The fans kicking on here is normal under GPU load.

Geekbench AI

Interpretation: These scores are in line with expectations for a CPU-based AI workload, showing the system can handle basic AI tasks but isn’t optimized for heavy machine learning compared to systems with dedicated AI hardware.

Cinebench

Interpretation: This lands right in the expected range for this class of processor for this class of processor, confirming stable multi-core performance during sustained workloads without aggressive throttling.

FurMark

During stress testing with FurMark at 3440 × 1440, the system remained impressively controlled. Temperatures peaked at around 66°C, with the fan only ramping up once the system reached the mid-60s. Even under sustained load, the system felt stable and responsive, with no obvious signs of thermal strain.

Interpretation: Temperatures peaking around 66°C at a high resolution like 3440 × 1440 is better than expected for a mini PC, indicating efficient cooling and no thermal issues under GPU stress.

Handbrake (4K → 1080P encode)

To evaluate real-world performance, I used HandBrake to transcode a 4K video file down to 1080p using the Fast 1080p30 preset. This test puts sustained load on the CPU and is a good indicator of both raw performance and thermal efficiency. The system completed the encode in 8 minutes and 46 seconds, maintaining consistent performance throughout the process.

Interpretation: This is a strong result for this processor, showing it can handle sustained CPU-heavy tasks efficiently with consistent performance and no noticeable slowdowns.

Network Speed Test (Ookla)

For comparison sake, I tested my MacBook Pro (M4, 14-inch) at the same time and got the following results.

Interpretation: These speeds are solid and consistent with what you’d expect over a stable connection, showing the system’s networking is performing reliably. Compared to the MacBook Pro (M4, 14-inch), speeds are lower but still well within a usable range for everyday tasks.

User Impressions

In addition to the benchmark tests, I had some additional thoughts about this tiny computing machine.

DESIGN: In general, I love the design of Mini PCs. They are compact and make great options for compact workspaces. Some of the cases I’ve seen have awkwardly placed ports, which makes it hard for cable management. The E3B’s ports are planned out nicely. The front has the audio port, 2 x USB-A ports, and the Type-C port. This makes it easy to connect different devices (like flash drives or charging cables) without straining to wrap cables around the back. The only downside to this configuration is that the Type-C port is the third display i/o port. So if you plug a third display in permanently, the cable will be sticking out of the front. Aside from that, I love the amount of i/o ports and the fact that a mount option is included.

GENERAL PERFORMANCE: Everyday tasks like email, web browsing, document editing, and spreadsheet work ran without any issues. It works well as a daily system for general productivity, but it isn’t built for demanding gaming. Lighter or casual titles should perform fine, while more graphics-heavy games will quickly push it beyond its limits.

Conclusion

The KAMRUI E3B Mini PC delivers exactly what it sets out to do: provide a compact, efficient desktop experience for everyday productivity without unnecessary complexity. Across benchmarks and real-world testing, it showed consistent CPU performance, stable thermals, and reliable day-to-day responsiveness. Overall, this is a well-balanced mini PC that makes the most of its form factor. It’s not trying to replace a high-end desktop, but it succeeds at being a dependable, space-saving workstation.
