NVIDIA's Tegra X1 Delivers Stunning Performance On Ubuntu Linux

NVIDIA's Tegra X1 64-bit ARM SoC running (non-Android) Linux is a beast! I was given access to a SHIELD Android TV that was configured to run Ubuntu Linux, which has led for some exciting benchmarks. In some workloads, the Tegra X1 comes up just shy of an Intel Core i3 "Broadwell" system. The Tegra X1 has me very excited about the future of ARMv8 hardware on Linux and NVIDIA's continued Tegra advancements.

Are Open-Source GPU Drivers Sufficient For 4K Linux Gaming?

Last week I published the results of a 15-way AMD/NVIDIA GPU comparison for 4K Linux gaming that was centered around the proprietary AMD/NVIDIA graphics drivers. However, if you stick to using open-source Mesa/Gallium3D drivers and are a Linux gamer, here are some benchmark results comparing the open to closed-source driver performance at 3840 x 2160.

Silicon Power S60: A $50 SSD To Try Under Linux

Earlier this month I posted a few benchmarks of one of the cheapest, sub-$40 SSDs under Ubuntu Linux. In needing another solid-state drive for one of the systems in the test lab that's focused on tracking other areas of the Linux kernel's performance on a daily basis, I went searching for another low-cost solution. This latest SSD purchase was the Silicon Power 120GB S60, which retails for about $50 USD.

QEMU Vulnerability Exposes The Host Through Emulated CD-ROM Drive

Back in May was the big "VENOM" security vulnerability affect QEMU whereby VM security could be escaped through QEMU's virtual floppy disk drive. In June was a PCNET controller buffer overflow allowing a guest to escape to have host access. Today there's a similar security vulnerability going public about its virtual CD-ROM drive.

See How Your Linux System Stacks Up To 15 GPUs For 1080p Gaming

This week I posted the results of a 15-way graphics card comparison on Ubuntu Linux with AMD Radeon and NVIDIA GeForce graphics cards while running the very latest proprietary drivers. Those tests were focused on 4K resolution testing in order to stress the latest-generation AMD/NVIDIA GPUs. However, if you want to see 1080p numbers, here are some benchmark-friendly results.

Purism Librem Laptops Remain Blobbed Up, Less Than Interesting

While it's been several months since the Purism Librem crowd-funding campaing got underway for producing "the first high-end laptop in the world that ships without mystery software in the kernel, operating system, or any software applications," the Librem 15 still relies upon a proprietary BIOS and there's still no easy fix.

The New AMD GPU Open-Source Driver On Linux 4.2 Works, But Still A Lot Of Work Ahead

With the Linux 4.2 kernel settling down nicely and AMD developers having already sent in a few round of fixes for their new AMDGPU kernel DRM driver, I've started testing out this new kernel driver -- plus the new xf86-video-amdgpu DDX and the associated new Mesa/LibDRM code -- that is providing the open-source accelerated graphics support for Tonga and all new/future GPUs like Carrizo and Fiji.

A New MIPS Creator CI20 Is Running Much Better

Last month I wrote about trying to benchmark the MIPS Creator CI20, a low-cost MIPS development board from Imagination Technologies, but sadly those plans were thwarted by stability issues. Fortunately, it was just a faulty board and the replacement board has been running without any faults.

Where AMD's Catalyst Driver Does The Best On Linux

Earlier this week I finished up a 15-way AMD/NVIDIA graphics card comparison on Linux with the very latest proprietary Linux drivers. That earlier article focused on the OpenGL performance and simply put the Catalyst performance on the tested Radeon hardware was abysmal compared to NVIDIA's Linux driver performance. However, there is one area where the Catalyst Linux driver really excels at performance and routinely beats out the green competition.
