Intel Firmware Engineers Make An Important Power Improvement For Sapphire Rapids

26. Červenec 2022 - 10:20
Earlier this year I wrote about the Intel Idle driver support being prepared for Xeon "Sapphire Rapids" CPUs but a limitation with these forthcoming Xeon Scalable processors was that C1 and C1E c-states handling are now mutually exclusive. Unlike earlier Xeon processors, C1 and C1E states couldn't be enabled at the same time. Fortunately, via new Intel firmware they have managed to overcome this limitation...

AMD Radeon 680M Graphics Are A Great Upgrade With RDNA2, Excellent On Linux

25. Červenec 2022 - 16:15
Last week when posting my initial Linux benchmarks of the AMD Ryzen 7 PRO 6850U performance (and also looking at the AMD Rembrandt Windows vs. Linux speed), there were two main areas to get excited about with these AMD Zen 3+ SoCs: nice power efficiency improvements across many real-world workloads and the graphics upgrade with the integrated Radeon 680M. In this article are more tests of the Radoen 680M graphics looking at the integrated graphics speed-up with RDNA2 finally replacing Vega as a big upgrade and also how this compares to the Intel Alder Lake P Xe Graphics performance for Linux laptops.

The Fedora Linux Rawhide Kernel Is Becoming Too Slow With Its Many Debug Options

24. Červenec 2022 - 11:57
Fedora is one of the Linux distributions that ships with a plethora of debug options during its "Rawhide" development phase to ease in diagnosing issues that turn up during testing rather than building everything in a release mode during the development cycle. While these debug options are good for debugging, the performance impact continues adding up and reaching a point that the Fedora Rawhide debug kernel is too slow for some tasks...
