A Look At The Windows 10 vs. Linux Power Consumption On A Dell XPS 13 Laptop

With the current-generation Dell XPS 13 XPS9370-7002SLV currently being tested at Phoronix, one of the areas I was most anxious to benchmark was the power consumption... For years it has been a problem of Linux on laptops generally leading to less battery life than on Windows, but in the past ~2+ years there has been some nice improvements within the Linux kernel and a renewed effort by developers at Red Hat and elsewhere on improving the Linux laptop battery life. Here are some initial power consumption numbers for this Dell XPS 13 under Windows 10 and then various Linux distributions.

The Dell XPS 13.3-inch laptop for testing features the Intel Core i7 8550U (quad-core + HT) CPU with UHD Graphics 620, 2 x 4GB RAM, 256GB PM961 NVMe Samsung SSD, and its panel is a 1920 x 1080 resolution. For some initial basic tests I ran Windows 10 out-of-the-box and compared that to fresh installs of Ubuntu 18.04 LTS, Fedora Workstation 28, openSUSE Tumbleweed, and Clear Linux.

Plus, just like Android users, Linux users can be pretty creative and only time will tell if they’ll be able to use Linux on DeX to make almost any Linux distro work. Read more

A Look At The GCC 9 Performance On Intel Skylake Against GCC 8, LLVM Clang 7/8

With GCC 9 embarking upon its third stage of development where the focus ships to working on bug/regression fixes in preparation for releasing the GCC 9.1 stable compiler likely around the end of Q1'2019, here is a fresh look at the GCC 9 performance with its latest development code as of this week compared to GCC 8.2.0 stable while using an Intel Core i9 7980XE test system running Ubuntu Linux. For good measure are also fresh results from LLVM Clang 7.0 stable as well as LLVM Clang 8.0 SVN for the latest development state of that competing C/C++ open-source compiler. Read more
