When it comes to kernel boot performance, Clear Linux remains very speedy in this regard while openSUSE Tumbleweed also boots much quicker than the default kernel of Ubuntu 19.04.

As we've routinely seen from other cross-distribution benchmarks, Clear Linux does perform the best for Intel's Scalable Video Technology (SVT) video encoder benchmarks, which in the case of the Coffeelake Xeon saw openSUSE Tumbleweed right behind.

In the case of x265 video encoding, openSUSE Tumbleweed had a one FPS advantage for the H.265 video encode performance on this passively cooled PC.

One of the few tests where Ubuntu 19.04 performed well against Clear Linux was for the Python PyBench test while openSUSE Tumbleweed was lagging behind.

For many of these tests, there isn't a measurable power difference between the three distributions and thus no significant thermal difference.
