Ubuntu 13.04 Desktop Comparison: 6 Desktops, 5 Driver/GPUs

In this article are benchmarks of six different desktops (Unity, GNOME Shell, GNOME Classic, KDE Plasma, Xfce, and LXDE) on five different GPU/driver configurations (Radeon, Catalyst, Intel, NVIDIA, and Nouveau) running the very latest Ubuntu 13.04 "Raring Ringtail" development packages to look at the latest state of the Ubuntu Linux gaming OpenGL performance.

There's Another Linux Kernel Power Problem

After last year discovering a major Linux kernel power regression that was widely debated until the Phoronix test automation software bisected the problem to get to the bottom of the situation, there's more active power regressions today on the Linux desktop. As I've mentioned on Twitter and in other articles in weeks prior there's a few regressions, but one of them for at least some notebooks is causing a very significant increase in power consumption. This situation that remains unresolved as of the Linux 3.7 kernel can cause the system to be going through about 20% more power.

LLVM/Clang vs. GCC On The ARM Cortex-A15 Preview

The latest ARM Cortex-A15 benchmarks on Phoronix is an extension of the earlier compiler testing from this modern ARM CPU found on the Samsung Exynos 5 Dual within the Samsung Chromebook. In this round of performance testing, the LLVM/Clang compiler performance is compared to recent releases of the GNU Compiler Collection on this latest-generation ARM hardware.

EXT4 File-System Tuning Benchmarks

Following last month's Btrfs file-system tuning benchmarks, in this article are a similar set of tests when stressing the EXT4 file-system with its various performance-related mount options. Here are a number of EXT4 benchmarks from Ubuntu 12.10 with different mount option configurations.

Benchmarking LLVM/Clang 3.2, GCC 4.8, DragonEgg Compilers

Earlier this week I shared some updated benchmarks of the latest development code for LLVM/Clang 3.2 on an Intel Core i7 processor. Now from this same setup to complement the LLVM 3.1/3.2 benchmarks are results of the GCC 4.7.2 compiler, the latest GCC 4.8 development snapshot, and benchmarks of GCC when using LLVM's DragonEgg 3.1/3.2-SVN optimizer plug-in.

LLVM/Clang 3.2 SVN On Intel Core i7

With LLVM/Clang 3.2 being released next month and the code branching occurring this month, here's some new benchmarks from the latest SVN development snapshot as of this weekend. LLVM/Clang 3.2 SVN benchmarks were compared to the earlier LLVM 3.1 and 3.0 releases for reference.

GCC 4.8 Compiler On AMD's Eight-Core Piledriver

This month from CPUs based upon AMD's new Piledriver micro-architecture I have delivered results of compiler tuning on AMD's Open64 compiler as well as GCC bdver2 tuning. That initial testing from an AMD FX-8350 Eight-Core processor didn't show any big boost out of the "bdver2" target with the new BMI/TBM/F16C/FMA3 instruction set extensions. Testing in this article from the AMD FX-8350 are GCC compiler benchmarks of the 4.6.3, 4.7.2, and 4.8.0 development snapshots to look for performance improvements on this new high-end AMD processor when using the very latest GCC compiler code.
