"AMD's Upcoming Zen 5 CPUs and AM5+ Platform Unveiled in Latest BIOS Updates"

AMD is reportedly developing a new AM5+ socket for upcoming Ryzen CPUs, as indicated by the MC Extractor tool detecting AM5+ and AMD processors with the 00B40Fxx CPUID. Speculation suggests these CPUs could be part of AMD's Granite Ridge or Fire Range lineup. The AM5+ socket is expected to replace the original AM5 in 2026 and may feature new capabilities such as USB4 version 2 and DisplayPort with UHBR20. AMD aims to reuse AM5 mechanical features to lower costs for partners and ensure backward compatibility with AM5 processors, while publicly committing to support the AM5 socket through 2025 and beyond.

"GNU Boot Project Removes Proprietary Code from Motherboards & CPUs"

The GNU Boot project, a fork of Coreboot/Libreboot aiming to provide free boot firmware, has removed certain non-free elements from its codebase in preparation for its v0.1 release. This includes AMD CPU microcode updates and motherboard ports that contained proprietary code. The affected motherboard ports were for older AMD Opteron server motherboards, which are favored by open-source enthusiasts despite being outdated. The project's commitment to free software led to the exclusion of these components to ensure the purity of its open-source ethos.
