Eventually, a steady state is reached with the GPU oscillating between 200 and 600 MHz, while the CPU cores stay put at the advertised 1.9 GHz. The GPU cranks up to 900 MHz while the CPU cores play second fiddle by dropping down to the base frequency (1.3 GHz). At the beginning of the test, we find that there is a bit of give-and-take between the CPU and the GPU for the TDP budget. The Core-Mе…ѓ20 advertises 1.9 GHz for the processor. For the Core i5-4250U, Intel advertises base clock speeds of 1.3 GHz for the cores and 200 MHz for the GPU. In the first graph, we see a plot of the various clock frequencies in the system and how they vary as the power virus test makes progress. Further light on this aspect is shed by the two graphs below. The above screenshot (taken just prior to stopping the power virus stress test) shows that the CPU isn't thermally throttled.

The i5-4250U has a Tjmax of 100C, and we found that the maximum temperature reached even after 4 hours of full loading of both CPU and GPU was around 95 C only (ambient at 70 F). The Habey BIS 6922 came out with flying colours. After that exercise, I was looking forward to evaluating other fanless PCs in order to gauge their thermal performance under heavy loading.

Aleutia had to get back to the drawing board after our findings were published.

The Relia ended up getting throttled when subject to heavy loading even at room temperature (72 F). The Aleutia Relia was one of the first fanless units that we evaluated for thermal throttling. For load power consumption, we ran Furmark 1.12.0 and Prime95 v27.9 together.

In the graphs below, we compare the idle and load power of the Core-Mе…ѓ20 with other low power desktop / industrial PCs. The power consumption at the wall was measured with the display being driven through the mini-HDMI port. Power Consumption and Thermal Performance
