The Best, Most Efficient Graphics Cards For 1080p Linux Gamers
Earlier this week I posted a graphics card comparison using the open-source drivers and looking at the best value and power efficiency. In today's article is a larger range of AMD Radeon and NVIDIA GeForce graphics cards being tested under a variety of modern Linux OpenGL games/demos while using the proprietary AMD/NVIDIA Linux graphics drivers to see how not only the raw performance compares but also the performance-per-Watt, overall power consumption, and performance-per-dollar metrics.

AMD Linux Graphics: The Latest Open-Source RadeonSI Driver Moves On To Smacking Catalyst
Following this weekend's Radeon R9 Fury open-source Linux driver tests with the DRM-Next code to be merged into Linux 4.3, the latest Mesa 11.1-devel Git code, and LLVM 3.8 SVN for the AMDGPU compiler back-end, I proceeded to run some bleeding-edge open-source Radeon Gallium3D graphics versus AMD Catalyst Linux benchmarks on Ubuntu.

GNOME 3.18 On Fedora 23: X.Org vs. Wayland Performance
With GNOME 3.18 having many Wayland improvements, I decided to test out the GNOME 3.18 stack on Fedora 23 Beta when running GNOME on a conventional X.Org Server and then using GNOME on Wayland while running various OpenGL games.

PHP 7.0 Is Showing Very Promising Performance Over PHP 5, Closing Gap With HHVM
With PHP 7.0 RC2 having just been released, I've been testing it out thoroughly across a range of Linux systems at Phoronix. To the say the least, the performance claims made by PHP developers about the upcoming PHP7 release are very accurate: it's pretty darn fast and about twice as fast as PHP 5.6. Here are some benchmarks I did on Ubuntu Linux x86_64 comparing the performance of PHP 7.0 RC2 to PHP 5.3/5.4/5.5/5.6, along with some HHVM results tossed in at the end.

The Linux 4.3 Kernel Is Bringing Many New Features & Improvements, But No KDBUS
Linus Torvalds released Linux 4.3-rc1 yesterday, a day earlier than planned, to ward off any subsystem/driver maintainers from sending in last-day pull requests. With the merge window now closed for Linux 4.3, here's a look at our highlights for the new and improved functionality of this next Linux kernel release.

The Performance Gains Made By AMD's RadeonSI Open-Source Driver In Two Years
Earlier this week we took a look at the AMD Radeon R600 Gallium3D performance over two years by benchmarking every Ubuntu Linux release since early 2013 with a Radeon HD 6000 series graphics card. Today up for your viewing pleasure are the results from a similar test but using a Radeon Rx 200 series graphics card with the newer RadeonSI Gallium3D driver for open-source AMD GCN GPUs.
