Testing F2FS With Its Multi-Drive Capabilities

Late last year F2FS picked up multiple device support for this Flash-Friendly File-System. This F2FS multi-drive capability isn't native RAID support like Btrfs but just allows a single F2FS file-system to span multiple devices. But it's more than that in that block allocation and the garbage collection policy is modified to boost I/O performance by taking advantage of the multiple SSD/flash devices.

NVIDIA 381 Linux Beta vs. Linux 4.11 / Mesa 17.1 Radeon Comparison

For those wondering how the bleeding-edge open-source Radeon driver stack is comparing to the latest NVIDIA closed-source binary blob, here are some fresh benchmarks on many different cards. Tested is the new NVIDIA 381.09 binary driver with different Maxwell/Pascal GPUs alongside various AMD GCN card tests using the Linux 4.11 Git kernel and Mesa 17.1-dev Git.

Benchmarks Of Many ARM Boards From The Raspberry Pi To NVIDIA Jetson TX2

For some weekend benchmarking fun, I compared the Jetson TX2 that NVIDIA released this weekend with their ARM 64-bit "Denver 2" CPU cores paired with four Cortex-A57 cores to various other ARM single board computers I have access to. This is looking at the CPU performance in different benchmarks ranging from cheap ~$10 ARM SBCs to the Raspberry Pi to the Jetson TX1 and Jetson TX2.

26-Way Intel/AMD CPU System Comparison With Ubuntu 16.10 + Linux 4.10 Kernel

In preparation for Intel Kaby Lake socketed CPU benchmark results soon on Phoronix, the past number of days I have been re-tested many of the systems in our benchmark server room for comparing to the performance of the new Kaby Lake hardware. For those wanting to see how existing Intel and AMD systems compare when using Ubuntu 16.10 x86_64 and the latest Linux 4.10 Git kernel, here are those benchmarks ahead of our Kaby Lake Linux CPU reviews.

The New Features & Exciting Changes Of The Linux 4.10 Kernel

Linus Torvalds is expected to release the Linux 4.10-rc1 kernel this weekend ahead of Christmas and thereby marking the formal end of the 4.10 merge window, but with all of the major pull requests already submitted and Linus tending not to honor last-minute pull requests of big changes, here is our usual look at the exciting changes and new features you will be able to find with the Linux 4.10 kernel.

Apple's 2016 MacBook Pro & Linux Don't Mix

Last month I shared that Linux tests of the 2016 MacBook Pro would be coming and now I've finally managed to complete a few, but I highly encourage you not to get the new MacBook Pro if you plan on using anything other than macOS as the experience is a wreck. This is one laptop I don't mind seeing returned!

Intel Kaby Lake Linux Testing With MSI's Cubi 2 Mini PC

Kaby Lake mobile processors began shipping last month and while we've seen a number of laptop designs using these processors that succeed Skylake, so far the Intel NUCs haven't surfaced nor many other SFF PCs making use of the next-generation hardware. That changed last week with MSI's Cubi 2 powered by Kaby Lake CPUs beginning to ship. I've been testing an MSI Cubi 2 with Core i5 Kaby Lake processor under Ubuntu Linux and so far the experience has been pleasant. In this article are our first Kaby Lake Linux benchmarks.

PocketCHIP Shipping In Mass Next Month - Makes Fun $69 Debian Linux Handheld

It's been a few months since Next Thing Co's C.H.I.P. computer was successfully funded on Kickstarter as "the world's first $9 computer" along with the PocketCHIP, a C.H.I.P. powered, battery-backed handheld with physical keyboard. Next Thing Co shipped to their backers over the summer whole in November they expects to begin shipping mass production orders on the CHIP and PocketCHIP. Over the past few weeks I've been playing with these low-cost ARM devices.

A Wild 40-Way Linux System Benchmark Comparison

With recently having upgraded some of the systems in our benchmark lab, commissioned a few new systems, and made some other changes, for your weekend enjoyment are some fresh benchmarks of 40 distinctly different Linux systems various performance tests.

A One Year Redux On The Basement Computer Room For Benchmarking 50+ Systems Daily

It was just over one year ago that I wrote about turning a basement into a big Linux server room (and then the six month redux). With having just finished tiling the floor and making some other modifications, here is a one-year look at the project where there are more than fifty systems running Linux/open-source benchmarks daily as part of Phoronix, OpenBenchmarking.org, and LinuxBenchmarking.com, among other Phoronix Media efforts for enriching the Linux hardware experience.

ODROID-C2 ARM SBC Offers Great Performance For $40

Hardkernel's ODROID-C2 64-bit ARM single board computer retails for $40 USD and is powered by an Amlogic S905 SoC. While just a fraction more than a Raspberry Pi 3 or the Pine 64+ when factoring in shipping costs, there's very competitive performance out of this board with its four cores running up to 2.0GHz.

Benchmarking The Low-Cost PINE 64+ ARM Single Board Computer

As an alternative to the Raspberry Pi 3 for a low-cost 64-bit ARM (AArch64) development board is the PINE 64, which was successfully Kickstarted as a "$15 64-bit single board super computer" that generated more than 1.7 million dollars. The PINE 64 is still shipping out in limited quantities for now, but the folks behind this project were kind enough to send over a sample of their PINE 64 1GB SBC for some benchmarking.

The CompuLab Airtop Continues Hitting Expectations As A High-Performance, Fanless PC

At the end of February I posted my initial hands-on with the passively-cooled Airtop PC that's been exciting many readers over its unique design and being Linux-friendly. As I hadn't written anymore about it in the past few weeks, some Phoronix readers had emailed me and tweeted, curious what the deal was and if it wasn't living up to expectations. That's not the case at all and the Airtop PC continues to exhibit great potential and is yet another solid offering from CompuLab.

Raspberry Pi 3 Benchmarks vs. Eight Other ARM Linux Boards

On Friday my Raspberry Pi 3 arrived for benchmarking. For our first benchmarks of this Cortex-A53 64-bit ARM $35 development board is a comparison against eight other ARMv7 and ARMv8 development boards running their official Linux distributions while carrying out a range of benchmarks. Here are those raw performance results along with a performance-per-dollar comparison for additional insight into this low-cost ARM development board.

Initial Hands-On With The Passively-Cooled Airtop PC Boasting A Core i7 & GTX 950

Since the Airtop PC was announced back in January there has been a lot of interest in this passively-cooled, high-performance line of PCs by the folks at CompuLab. The Airtop isn't some low-end, passively cooled PC but rather can be equipped with a Core i7 or Xeon CPU and a discrete graphics card to deliver very capable performance while having a completely silent PC. Some have been skeptical about the cooling and performance claims of the Airtop PC, but our review sample arrived this morning and have begun testing out this very interesting PC.

For $3100 USD You Can Have A Fast, Fully-Free-Software Workstation

Last week I brought up the Talos Secure Workstation as a $3100 USD system that's fully free and open down to the firmware and with an open-source friendly processor design while being high performance. Since then, I've had access to test out the hardware making up this POWER8-powered system to see how fast a fully-open system can be. Here is more information on the proposed Talos Workstation along with a few early Linux benchmarks.

With Skylake Out, It's Becoming Easier To Build A Cheap Haswell Xeon Linux System

Now that Skylake Xeon processors are appearing at major Internet retailers in sufficient quantities (such as the recently reviewed Intel Xeon E3 1245 v5), prices on older-generation Xeon CPUs are falling further. With prices on DDR3, SSDs, and Haswell-compatible motherboards also continuing to fall, it's possible to build a sufficiently powerful yet cheap Haswell Xeon system.

How Intel Laptop Performance & Efficiency Evolved From Nehalem To Broadwell

Last week I published a 7-way Linux laptop comparison with processors ranging from Sandy Bridge to Broadwell. Out of interest from readers in an even larger comparison, I've re-tested a Nehlaem-based "Clarksfield" laptop as well as a "Westmere" laptop to show how the raw performance and performance-per-Watt compare to the Sandy Bridge, Ivy Bridge, Haswell, and Broadwell devices.
