Linux 4.1 Power Consumption Appears To Improve For Intel Users

A Red Hat developer mentioned to us at Phoronix that they're seeing "drastically improved battery life" in some cases with the Linux 4.1 kernel to the extent that it's up to 2~4 hours of extra battery life with the kernel upgrade to Git. I've since started some fresh Linux laptop battery tests.

The Lenovo T450s Is Working Beautifully With Linux

A couple weeks ago I bought the Lenovo T450s, this is my first laptop-upgrade in about three years and I have to say... I am so glad that I did upgrade. Over the last two weeks I've been using the T450s as my daily-driver and its been working almost perfectly under Fedora Linux.

Lenovo ThinkPad T450s Broadwell Preview

This is a "first impression" review. I've had the system in my hands for all of about twenty-four hours and am still exploring and forming more solid opinions. Also any problems I had likely do have solutions, but as I said: less than forty-eight hours of ownership so I haven't had a chance to. Linux-centric system review will follow this weekend / next week.

Turning A Basement Into A Big Linux Server Room

This week I posted about my new server room, where there's Linux benchmarks constantly happening on the Linux kernel and other open-source code via the Phoronix Test Suite and Phoromatic. With many Phoronix readers having been interested in the basement makeover I did to turn a ugly, boring basement into a clean server room, here's more details and pictures on the month-long renovation along with various tips and product recommendations from the experience. This server room is now almost up to 50 systems and is complete with a drink bar and projector. There's plenty of pictures and details for those hoping to build their own personal basement server room, including a few tips for increasing the wife acceptance factor of the big project.

Lenovo ThinkPad X1 Carbon Works Great As A Linux Ultrabook

Nearly one month ago I bought the third-generation Lenovo ThinkPad X1 Carbon as one of the first laptops/ultrabooks shipping with a high-end Broadwell processor. I've been running Linux on the system since receiving it, including the past ~3 weeks as my main production system, and I remain very happy with this purchase.

9-Way Linux Laptop Performance Comparison From Intel Nehalem To Broadwell

As the latest Linux benchmark numbers to deliver for Intel Broadwell and the new ThinkPad X1 Carbon ultrabook, here's a nine-way Linux laptop/ultrabook comparison. All nine devices in this article were tested against the latest snapshot of Ubuntu 15.04 while running a big set of benchmarks and also monitoring the CPU temperatures and battery power consumption while testing for a nice look at Clarksfield/Nehalem, Sandy Bridge, Ivy Bridge, Haswell, and Broadwell mobile hardware on Linux.

A First Look At The Intel Broadwell NUC Kit

With wrapping up my Core i7 5600U Broadwell Linux tests using the new ThinkPad X1 Carbon in the next few days, fortunately the Intel BOXNUC5I3RYH just arrived as the first available NUC Kit shipping with a Broadwell processor. The NUC5i3RYH features a Broadwell Core i3 processor, HD Graphics 5500, and support for a M.2 SSD card and 2.5-inch HDD/SSD.

A Walkthrough Of The New 32 System Open-Source Linux Benchmarking Test Farm

This week with the release of Phoronix Test Suite 5.4 we also announced LinuxBenchmarking.com, a collection of 32 systems running various upstream benchmarks on a daily basis in a fully automated manner. The daily upstream benchmarking ranges from the Linux kernel Git to Mesa to Arch/Antergos Linux to LLVM/Clang. Here's a walkthrough of the new lab housing this test farm where hundreds of benchmarks are run daily in looking for performance regressions and other changes with the upstream open-source code.

CompuLab Intense-PC2: An Excellent, Fanless, Mini PC Powered By Intel's i7 Haswell

Last month in a preview article I mentioned I was testing CompuLab's Intense-PC2 and that it was a great Haswell-based mini Linux PC. After using it now for another month and putting it through its paces with many strenuous benchmarking workloads and trying out other Linux distributions, I remain enthusiastic about the Intense-PC2 and it being a great offering for Linux (and even Windows/BSD) users.

From The Atom 330 To Haswell ULT: Intel Linux Performance Benchmarks

For the past month I've been testing out the CompuLab Intense-PC2 and it's been a terrific, small, Linux PC. The Intense-PC2 is packed with a low-power "Haswell ULT" Core i7 4600U processor and for some fresh Linux benchmarks I compared it to the former Sandy Bridge Core i7 3517UE and Intel Bay Trail Celeron N2820 NUC. For making things real interesting, I also ran some new benchmarks on an aging Intel Atom 330 system to show how the Intel low-power performance has been improving in recent years.
