The "Chinese EPYC" Hygon Dhyana CPU Support Still Getting Squared Away For Linux

Back in June is when the Linux kernel patches appeared for the Hygon Dhyana, the new x86 processors based on AMD Zen/EPYC technology licensed by Chengdu Haiguang IC Design Co for use in Chinese data-centers. While the patches have been out for months, they haven't reached the mainline kernel quite yet but that might change next cycle.

NVIDIA GeForce RTX 2080 Ti Shows Very Strong Compute Performance Potential

Besides the new GeForce RTX 2080 series being attractive for developers wanting to make use of new technologies like RTX/ray-tracing, mesh shaders, and DLSS (Deep Learning Super Sampling), CUDA and OpenCL benchmarking so far on the GeForce RTX 2080 Ti is yielding impressive performance -- even outside of the obvious AI / deep learning potential workloads with the Turing tensor cores. Here are some benchmarks looking at the OpenCL/CUDA performance on the high-end Maxwell, Pascal, and Turing cards as well as an AMD Radeon RX Vega 64 for reference. System power consumption, performance-per-Watt, and performance-per-dollar metrics also round out this latest Ubuntu Linux GPU compute comparison.

NVIDIA Sends Out DRM Display Patches For Tegra's Xavier SoC

Going back to the beginning of the year NVIDIA developers have been contributing "Tegra194" enablement to the upstream Linux kernel. They've now moved on to contributing T194 support to the Tegra Direct Rendering Manager (DRM) driver for display support on this SoC that's better known as Xavier.

NVIDIA GeForce GTX 680 To RTX 2080 Ti Graphics/Compute Performance

Yesterday were the initial NVIDIA GeForce RTX 2080 Ti Linux benchmarks based upon my early testing of this high-end Turing graphics card paired with their new 410 Linux graphics driver. For your viewing pleasure today is a look at how the RTX 2080 Ti compares to the top-end cards going back to Kepler... Or, simply put, it's the GeForce GTX 680 vs. GTX 780 Ti vs. 980 Ti vs. 1080 Ti vs. 2080 Ti comparison with OpenGL and Vulkan graphics tests as well as some initial OpenCL / CUDA tests but more Turing GPU compute tests are currently being conducted. For making this historical comparison more interesting are also power consumption and performance-per-Watt metrics.

Purism Announces The "Librem Key"

Remember back in May when Purism partnered up with Nitrokey as they wanted to work on a USB-based PGP SmartCard? They have now announced the Librem Key as a result of that work.

Nouveau Developers Begin Reverse-Engineering NVIDIA Turing Driver Support

The NVIDIA GeForce RTX 2080 graphics cards are only officially beginning to ship today, but at least one independent Nouveau developer already has his hands on the hardware and beginning to work on the clean-room, driver reverse-engineering process in order to eventually get open-source "Nouveau" driver support working.

Vulkan 1.1.85 Released With Raytracing, Mesh Shaders & Other New NVIDIA Extensions

Leading up to the Turing launch we weren't sure if NVIDIA was going to deliver same-day Vulkan support for RTX/ray-tracing with the GeForce RTX graphics cards or if it was going to be left up to Direct3D 12 on Windows for a while... Fortunately, as already reported, their new driver has Vulkan RTX support. Additionally, the NVX_raytracing extension and other NVIDIA updates made it into today's Vulkan 1.1.85 release.

Opus 1.3 Codec Library Nears, New Tools Release

Back in June was the first release candidate of Opus 1.3 (libopus v1.3) with this open-source audio codec allowing to use SILK down to bitrates of about 5kb/s, wideband encoding down to 9kb/s, improved security, improved Ambisonics support, and much more. Libopus 1.3 RC2 is now available along with some tooling updates.
