>I just wish AMD and Intel could work together and make a subset clean up of x86 ISA

AMD and Intel Celebrate First Anniversary of x86 Ecosystem Advisory Group Driving the Future of x86 Computing

Standardizing x86 features

Key technical milestones, include:

    FRED (Flexible Return and Event Delivery): Finalized as a standard feature, FRED introduces a modernized interrupt model designed to reduce latency and improve system software reliability.
    AVX10: Established as the next-generation vector and general-purpose instruction set extension, AVX10 boosts throughput while ensuring portability across client, workstation, and server CPUs.
    ChkTag: x86 Memory Tagging: To combat longstanding memory safety vulnerabilities such as buffer overflows and use-after-free errors, the EAG introduced ChkTag, a unified memory tagging specification. ChkTag adds hardware instructions to detect violations, helping secure applications1, operating systems, hypervisors, and firmware. With compiler and tooling support, developers gain fine-grained control without compromising performance. Notably, ChkTag-enabled software remains compatible with processors lacking hardware support, simplifying deployment and complementing existing security features like shadow stack and confidential computing. The full ChkTag specification is expected later this year – and for further feature details, please visit the ChkTag Blog.
    ACE (Advanced Matrix Extensions for Matrix Multiplication): Accepted and implemented across the stack, ACE standardizes matrix multiplication capabilities, enabling seamless developer experiences across devices ranging from laptops to data center servers.
