June 14, 2012 -- Last week I shared my plans to build a low-cost, 12-core, 30-watt ARMv7 cluster running Ubuntu Linux. The ARM cluster that is built around the PandaBoard ES development boards is now online and producing results... Quite surprising results actually for a low-power Cortex-A9 compute cluster. Results include performance-per-Watt comparisons to Intel Atom and Ivy Bridge processors along with AMD's Fusion APU.

May 22, 2012 -- The Linux OpenCL support for Intel CPUs is not in as good shape as the Intel Windows OpenCL support at this time, but here are some benchmarks that explore the Intel Ivy Bridge OpenCL performance under Linux.

April 23, 2012 -- Intel is finally announcing the first Ivy Bridge processors this morning. I have been extensively testing out the Intel Core i7 3770K, the current high-end Ivy Bridge processor, for the past few weeks under Ubuntu Linux. I have been extremely pleased with the Intel Core i7 Ivy Bridge processor under Linux with its phenomenal performance, power efficiency, and new features. This article is the first of many looking at the Linux performance of the new Intel Ivy Bridge processors.

March 28, 2012 -- With the upcoming availability of Ubuntu 12.04 "Precise Pangolin" being a Long-Term Support (LTS) release that will be quickly making its way into many enterprise environments, here's a look at the virtualization performance of this popular Linux distribution. In particular, being looked at is the Linux virtualization performance of KVM, Xen, and Oracle VirtualBox compared to bare metal when using Intel Sandy Bridge Extreme and AMD Bulldozer hardware.

December 26, 2011 -- Following the interest yesterday from the AMD A8-3870K graphics testing even though this new Llano APU has the same Radeon HD 6550D integrated graphics as the original A8-3850 APU, here's some more information and numbers from the week-old AMD A8-3870K when running the desktop AMD APU under Ubuntu Linux and attempting to overclock this week-old Llano APU.

December 19, 2011 -- Using the new Intel Core i7 3960X Extreme Edition Sandy Bridge processor, Scientific Linux 6.1, Debian GNU/Linux, Debian GNU/kFreeBSD, and Solaris 11 11/11 were benchmarked when having a different number of CPU cores enabled to see how well each operating system scales up to six cores plus Hyper Threading.

December 13, 2011 -- By now you have likely heard of the Core i7 3960X processor, which is one of the Sandy Bridge Extreme CPUs that was launched in November by Intel to much excitement and talked about quite a bit on Phoronix in the past few days. In this article is a comprehensive look at the Intel Core i7 3960X performance under Ubuntu Linux.

November 22, 2011 -- While in the weeks since the launch of the AMD FX "Bulldozer" processors we have looked at many areas of computing performance for the FX-8150 CPU, from the compiler tuning to multi-core scaling, one area that hasn't yet been covered under Linux is the AMD FX-8150 overclocking. But this article changes that.

November 16, 2011 -- For those wondering about the impact that AMD's Cool 'n' Quiet and Turbo Core technologies have under Linux for the latest-generation Bulldozer processors, here are some tests illustrating the changes in performance, power consumption, and operating temperature.

November 04, 2011 -- With the renewed interest in the Gallium3D LLVMpipe driver now that this software-based acceleration method is working with GNOME Shell, here are some benchmarks of this LLVM-based software driver when running some OpenGL tests on Intel Sandy Bridge and AMD Bulldozer hardware.
