Radeon Software 18.50 vs. Linux 4.20 + Mesa 19 Benchmarks On The AMD RX 590

While Windows users last week were greeted by the Radeon Software Adrenalin 2019 driver on the Linux side was the Radeon Software for Linux 18.50 release. The only listed public change for this 18.50 Linux hybrid driver build was RHEL 7.6 support, but I've since been able to test and confirm that the Radeon RX 590 is working with this new Linux driver package. As a result, here is a look at the Radeon RX 590 performance from this "AMDGPU-PRO" driver build compared to the latest open-source driver stack in the form of Linux 4.20 with Mesa 19.0-devel.

Linux 4.14 vs. 4.20 Performance Benchmarks - The Kernel Speed Difference For 2018

As some additional end-of-year kernel benchmarking, here is a look at the Linux 4.14 versus 4.20 kernel benchmarks on the same system for seeing how the kernel performance changed over the course of 2018. Additionally, Linux 4.20 was also tested a second time when disabling the Spectre/Meltdown mitigations that added some performance overhead to the kernel this year.

Ubuntu 18.04 LTS Now Available On Select Dell Precision Laptops

While it's great that Dell offers the ability to have Ubuntu Linux pre-loaded on select systems, one of their shortcomings is that they are often quite slow in supporting new Ubuntu LTS releases. At least now for select Dell Precision mobile workstation laptops, they have finally switched over to Ubuntu 18.04 LTS.

Five-Way Linux OS Comparison On Amazon's ARM Graviton CPU

Last month Amazon rolled out their "Graviton" ARM processors in the Elastic Compute Cloud. Those first-generation Graviton ARMv8 processors are based on the ARM Cortex-A72 cores and designed to offer better pricing than traditional x86_64 EC2 instances. However, our initial testing of the Amazon Graviton EC2 "A1" instances didn't reveal significant performance-per-dollar benefits for these new instances. In this second round of Graviton CPU benchmarking we are seeing what is the fastest of five of the leading ARM Linux distributions.

Enabling Intel Fastboot Support By Default Brought Up, Again

The Intel DRM "Fastboot" option is what allows skipping a mode-set upon the device initalization during the Linux boot process to allow for a slick and smooth Linux desktop boot experience free of any excess flickers. While Intel Fastboot has been an option for years, it isn't yet the default behavior for this graphics driver.
