🛠️ Technical Specifications Table

🎨 Design and Construction Quality

The chassis maintains BMAX's usual compact aesthetic, with a black/green finish and a size of just 125×112×33mm, making it lightweight despite housing a more powerful processor than other models from the brand. It incorporates a cooling system with dual copper heat pipes to better manage the heat of a chip that is more demanding than a basic Celeron.

The included VESA mount allows it to be mounted behind a monitor, and the Clear CMOS button visible on the chassis is a handy feature for technicians or advanced users who need to reset the BIOS.

🖥️ Screen and Multimedia

The B6 Turbo supports dual 4K@60Hz monitors by combining HDMI 1.4 and DisplayPort 1.2, a configuration designed for dual-screen workstations or editing with a secondary reference monitor. The integrated Iris Plus 645 GPU offers a significant performance leap compared to the basic UHD Graphics in Celeron processors: it handles video encoding/decoding more efficiently and supports photo retouching or light editing tasks without noticeable bottlenecks.

It does not include its own speakers, so you will need a monitor with integrated audio or an external sound system connected to the 3.5mm jack.

🎮 Performance and Software: Windows and Linux

This is where the B6 Turbo clearly differentiates itself from the rest of the BMAX range. According to the manufacturer's own data, the i5-8257U achieves a score of 7427 in PassMark, 104% higher than the previous generation of Core i5, and 3136 points in PCMark 10 Express, surpassing even systems with the latest Core i5-1030NG7 (3120 points).

In actual use this translates to:

• Seamless multitasking with dozens of tabs open and multiple simultaneous office applications

• Good performance in suites like Adobe Photoshop or Lightroom for light editing

• Code compilation and lightweight virtual machines without frequent crashes

Windows 11 Pro comes pre-installed with TPM 2.0 support, meeting Microsoft's official requirements without the need for workarounds. The manufacturer confirms compatibility with Ubuntu 22.04 LTS, although it requires manual installation (it is not pre-installed).

Since the hardware is considerably more powerful than entry-level Celeron processors, the performance jump when switching to Linux is less dramatic than in those models, but it's still a viable option if you're looking to maximize the computer's energy efficiency or use it as a server.

🔌 Energy Consumption and Cables

The i5-8257U is officially rated at 15W according to the manufacturer's datasheet and several distributors, although one store mentions 28W, possibly confusing it with the chip's maximum configurable TDP in other scenarios.

The included adapter delivers 12V/3A (36W), with enough headroom for peak consumption under sustained load with both M.2 slots occupied and the USB ports in use.

🌡️ Temperature and Noise (Actual Thermal)

Thanks to the dual copper heat pipe system, the B6 Turbo manages temperatures better than mini PCs with more basic cooling, despite running a chip with a higher TDP than the Celeron processors in the BMAX range.

The smart fan adjusts its speed according to the load: in light tasks it is virtually inaudible, and under sustained load (compilations, intense multitasking) it becomes somewhat more noticeable, although within reasonable levels for a device of this size.
