Windows 10 Outperforming Linux On A ~$5000 Laptop, Ubuntu Beating Clear Linux
We are used to seeing tier-one Linux distributions outperforming Microsoft Windows on hardware ranging from $199 laptops to HEDT and server processors and everything in between. Thus it came as a large surprise to us when finding Windows 10 outperforming multiple Linux distributions on a new Intel laptop. Not only was Windows 10 leading, but the performance paradigm shifted that Ubuntu was even outperforming Clear Linux, which normally is the fastest of Linux distributions out-of-the-box.

Ubuntu 20.04 LTS A Nice Upgrade For AMD Ryzen Owners From 18.04 LTS
Particularly for those on Ubuntu 18.04 LTS or derivative distributions based on the current long-term support base, moving to Ubuntu 20.04 LTS due out next month will yield some nice improvements particularly for those on newer platforms like the AMD Ryzen 3000 series. Here are some benchmarks at how the Ryzen 9 3900X performance is looking between Ubuntu 18.04.4 LTS, Ubuntu 19.10, and the current Ubuntu 20.04 LTS development snapshot.

The Brutal Performance Impact From Mitigating The LVI Vulnerability
On Tuesday the Load Value Injection (LVI) attack was disclosed by Intel and security researchers as a new class of transient-execution attacks and could lead to injecting data into a victim program and in turn stealing data, including from within SGX enclaves. While Intel has publicly stated they don't believe the LVI attack to be practical, one of their open-source compiler wizards did go ahead and add mitigation options to the GNU Assembler as part of the GCC toolchain. Here are benchmarks showing the performance impact of enabling those new LVI mitigation options and the significant impact they can cause on run-time performance in real-world workloads.

20-Way GPU Gaming Comparison With March 2020 Linux Drivers
Given the continuously evolving state of the open-source Radeon Linux graphics drivers in particular, here are fresh AMD Radeon vs. NVIDIA GeForce Linux gaming benchmarks with the latest Linux graphics drivers as we begin March 2020. Besides the latest NVIDIA 440.64 Linux driver, on the Radeon side was Mesa 20.1-devel paired with the Linux 5.5.5 kernel and also having the RADV ACO back-end enabled.

Ubuntu 20.04 LTS vs. Clear Linux On The Intel Core i9 9900KS, AMD Ryzen 9 3900X
While we have been seeing Ubuntu 20.04 LTS offer better performance with newer hardware platforms, how does the performance compare to Intel's performance-optimized Clear Linux? Here are some benchmarks on both AMD Ryzen 9 3900X and Intel Core i9 9900KS systems.

Ubuntu 18.04 vs. 20.04 LTS Performance Preview With Intel Xeon Scalable
There is less than one month to go until the official release of Ubuntu 20.04 LTS "Focal Fossa" but we've already begun experimenting with it for weeks across a variety of platforms. For the most part we have found Ubuntu 20.04 slated to offer some nice performance improvements, especially if upgrading from the existing LTS series, Ubuntu 18.04. In this article are our initial benchmarks looking at the Intel Xeon Scalable from Ubuntu 18.04 LTS to the current 20.04 near-final state.

Ubuntu 18.04/19.10/20.04 vs. Debian 10/Testing Benchmarks On AMD Ryzen
While Ubuntu is based on Debian, for those wondering how the performance of Ubuntu 20.04 LTS is looking not only compared to the previous 19.10 and 18.04.4 LTS releases but also Debian 10.3 stable and Debian Testing, here are some benchmark results on an AMD Ryzen 9 3900X system.

Intel Core i9 10980XE: FreeBSD 12.1 vs. GhostBSD 12.02 vs. DragonFlyBSD vs. Ubuntu Linux Benchmarks
Given the release earlier this month of DragonFlyBSD 5.8 along with the recent debut of the FreeBSD-based desktop-focused GhostBSD 20.02, here are benchmarks looking at their performance up against FreeBSD 12.1-RELEASE as well as the current state of Ubuntu 20.04. Tests were done both with the LLVM Clang and GCC compilers.

Basemark GPU 1.2 Brings Linux Support - Wins For NVIDIA, Woes For Mesa
Last week Basemark launched their Basemark GPU 1.2 benchmark that now includes Linux support alongside all other major supported desktop and mobile operating systems. We've been testing out this Linux version with OpenGL and Vulkan support on both AMD Radeon and NVIDIA GeForce hardware.
