Red Hat's David Airlie has been refocusing efforts recently on improving the state of the LLVMpipe driver that implements OpenGL / OpenGL ES on top of CPUs using LLVM. In the past few weeks he's been wiring up more GL4 / GLES 3.1 extensions and this morning the latest achievement is supporting OpenGL compute shaders!..

The Schedutil CPU frequency scaling governor has been around for a few years and has gotten better over time but in our own tests we still find it frequently not being as competitive to the "performance" governor and others. However, in the future Schedutil might become the default and perhaps only governor...

While we are often testing Intel's Clear Linux on high-end desktop and server hardware, it turns out even on the opposite end of the spectrum that their performance-optimized distribution can offer meaningful performance advantages on low-end SoCs for IoT-type devices. When testing Clear Linux with an Apollolake platform, it came out to being about 20% faster than the likes of Fedora and Ubuntu Linux.

Frequently brought up following our various Ryzen 3000 "Zen 2" benchmarks like the Ryzen 9 3900X vs. Core i9 9900K gaming benchmarks is how the Ryzen 9 3900X is pulling considerably more power than the similarly equipped Intel Core i9 system and those numbers are higher than what is often cited by Windows reviewers as the difference. I've begun investigating that power difference and indeed quite quickly could see Linux power usage being higher than Windows 10...
