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.

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 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.

GCC vs. Clang Compiler Benchmarking On Intel's Skylake CPU
Continuing in our compiler benchmarks this week are some GCC vs. Clang C/C++ compiler performance benchmarks on Intel's new Skylake processor while testing from Ubuntu Linux 64-bit.

Trying Out The Open-Source NVIDIA/Nouveau Driver Rework In Linux 4.3
With the forthcoming Linux 4.3 kernel is a big rework to the open-source NVIDIA (Nouveau) driver. Here are our first tests of NVIDIA GeForce hardware under Linux 4.2 stable and then the Linux 4.3 Git code with this reworked driver.

As always, if you appreciate Phoronix as the leading source of Linux gaming/enthusiast news, hardware, and benchmarks, take a moment to follow us on Facebook and Twitter. If you wish to support the work even further, there's Phoronix Premium that does a lot to complement the ad revenues as the primary source to ensure I can keep writing all these articles and running all of the Linux performance tests day-in and day-out.

There's a lot more interesting stuff happening later in September so stay tuned!
