BOSGAME VTA-439 Mini PC running Linux – Power Consumption

Power Consumption With Light Usage

In this test, I used each machine over many days while performing a variety of general desktop tasks, including web browsing, email, compiling source code, watching video, listening to music, and running virtual machines.

The chart shows total system power consumption, not just CPU power draw.

Under light load, the VTA-439 remains very efficient, drawing 15.9W in Balanced mode. It’s not quite as frugal as the Panther Lake Core Ultra 7 356H system, which manages 13.5W, but it’s still an excellent result for a Ryzen AI 9 HX 470 mini PC. The VTA-439 sits close to the Ryzen 9 7940HS system, below the Ryzen AI 9 HX 370 machine, and well below the Core Ultra 7 255H and Core Ultra 9 285H systems. This reinforces the point that low-load power consumption depends on the whole platform, not just the processor’s headline TDP.

Notes about the chart:

• The tasks do not include GPU-intensive activities such as gaming, running locally hosted AI apps, video recording, or live streaming.
• While the tests use software that accesses the GPU, such as Wayland, GPU load is minimal, with the exception of the i5-12400F, as that machine’s dedicated graphics card draws significantly more at idle.
• Two screens are used on each machine.
• The i5-12400F machine hosts a dedicated graphics card, whereas the other machines all use onboard graphics. The 285HX machine has a network card that draws around 10W when idle.
• The Balanced power profile is used.
• The machines are running Ubuntu.
