AMD EPYC 7H12 Announced As New 280 Watt Processor For High Performance Computing
From Rome, Italy this afternoon AMD not only announced more than 100 world records have been broken with their new EPYC "Rome" processors, but there is also a new SKU! Meet the EPYC 7H12.
The EPYC 7H12 doesn't quite follow the naming convention of the rest of the EPYC Rome line-up announced back in August as it's a special part. The EPYC 7H12 is more akin to Intel's Cascadelake-AP line-up but with more broad availability and just a higher clocked / higher power part as opposed to tacking on extra dies. But it carries the same focus on delivering maximum HPC performance.

NVIDIA Bringing Up Open-Source Volta GPU Support For Their Xavier SoC
While NVIDIA doesn't contribute much open-source Linux driver code as it concerns their desktop GPUs (though they have been ramping up documentation), when it comes to Tegra/embedded is where they have contributed improvements and new hardware support to Nouveau and associated driver code in the past several years. NVIDIA's open-source Tegra/embedded contributions come as a result of customer demand/requirements. Their latest work is preparing to finally bring-up the "GV11B" Volta graphics found within last year's Tegra Xavier SoC.

Valve's ACO Shader Compiler Under Review For The Mesa Radeon Vulkan Driver
The RADV "ACO" shader compiler announced by Valve back in July for the fastest compilation speeds and best possible code generation may soon be hitting mainline Mesa for the open-source AMD Linux graphics stack.
The ACO shader compiler as an alternative to the existing AMDGPU LLVM shader compiler back-end has shown quite promising results for Linux games. ACO has become more featureful over time and is now largely at feature parity to the existing shader compilation support while generally offering some performance advantages, thanks to the effort and funding by Valve.

Samsung, Red Hat to Work on Linux Drivers for Future Tech
The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world.
Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility.
