Intel's Fantastic New Open-Source Demonstrator For AMX-BF16: Over 4x The Performance At 69% The Power

13 janvier 2026 à 17:22
When it comes to software leveraging Intel Advanced Matrix Extensions (AMX) functionality in modern Xeon processors, it's largely been limited to AI applications/libraries like oneDNN, OpenVINO, DeepRec, etc. But Intel now has another great open-source real-world AMX demonstrator with their Open Image Denoise library. This open-source library providing high quality denoising filters for images rendered using ray-tracing can end up benefiting big time from AMX-FP16 (AMX-COMPLEX) found with the newest Xeon 6 "Granite Rapids" processors. I ran some benchmarks of their new Open Image Denoise library with AMX-FP16 and was honestly blown away by the results.

FFmpeg Merges A Number Of Vulkan Improvements To Start 2026

13 janvier 2026 à 14:15
FFmpeg developer Lynne has landed a number of Vulkan-related imporvements to this widely-used open-source multimedia library. Over the past year FFmpeg saw Vulkan shader-based decoding for more video formats, AV1 and VP9 extension work, performance improvements, and other work around Vulkan Video. It will be very exciting to see how FFmpeg delivers in 2026 with Vulkan Video and how the software ecosystem as a whole begins taking up this cross-platform, open industry standard for video encode/decode...

The Surprising Spectre BHI Mitigation Performance Impact On Meteor Lake

12 janvier 2026 à 19:38
When recently carrying out performance benchmarks of Intel Meteor Lake performance on Linux since launch day two years ago, the geo mean came in at 93% the original performance. Finding the performance trending clearly lower with an up-to-date Linux software stack compared to in December 2023 was quite surprising considering the rather nice gains we have seen over time on other Intel/AMD hardware. As noted in that article though, one of the possible explanations there is the Spectre BHI "Branch History Injection" vulnerability and microcode plus Linux kernel mitigations having come out post-launch and affecting Meteor Lake CPUs. Sure enough, follow-up tests looking at the Spectre BHI impact have revealed a measurable cost in a number of workloads for the Core Ultra processor.

LLMinus Working On AI/LLM-Powered Merge Conflict Resolution For The Linux Kernel

12 janvier 2026 à 14:08
Building off an initial request for comments (RFC) patch series posted during the winter holidays, an updated RFC patch series was posted this weekend for LLMinus. LLMinus is an effort led by NVIDIA Linux kernel engineer Sasha Levin to provide a large language model (LLM) assisted merge conflict resolution tool focused on Linux kernel development...

Linux Lands Safeguard For RISC-V Against Another Microarchitectural Attack Vector

11 janvier 2026 à 12:34
Increasingly complex RISC-V cores aren't magically immune to the speculative execution / side-channel vulnerabilities that have rattled the x86_64 and ARM64 landscape for years. Following recent work on Spectre V1 handling for RISC-V in the Linux kernel, merged this weekend for Linux 6.19-rc5 is another RISC-V attack vector safeguard...
