About this tag
The x86 processors tag on WindowsForum.com covers discussions about the x86 architecture, including CPU features and kernel support. Recent content highlights Linux 7.2 making the Time Stamp Counter (TSC) mandatory for x86 kernels, ending support for older processors like i486. This change affects maintainers and retro or embedded deployments, while mainstream PCs and servers remain unaffected. The tag explores how operating systems, including Windows, rely on x86 performance counters for timing and compatibility. Topics include hardware requirements, kernel development, and the evolution of x86 processor support across platforms.

    Intel and AMD CEOs Discuss Possible Cooperation, but Scope Remains Undisclosed

    Intel and AMD are talking about working together, and nobody has said what on. Intel CEO Lip-Bu Tan has discussed possible cooperation with AMD CEO Lisa Su, according to TechRadar. Mezha.net's English and Ukrainian pages carried the same story. The details are thin enough that the "mystery"...

    AMD and Intel Unify PyTorch x86 CPU Optimizations in oneDNN: What It Means

    AMD and Intel say they will merge their x86 CPU optimization work for PyTorch into one library. The companies plan to combine their x86 processor optimizations for PyTorch in oneDNN. The aim is a single software path for CPU-based AI, in place of separate vendor tracks. For anyone running...

    RISC vs. CISC Explained: Why Modern x86 and Arm CPUs Are More Alike Than Ever

    For decades, one of the favorite parlor games in PC hardware circles has been pitting CISC (Complex Instruction Set Computer) against RISC (Reduced Instruction Set Computer) as if they were two rival sports franchises playing completely different games. In the popular shorthand, the x86 chip...

    GCC Patch Review Adds -mavx10v1aux for Future AMD and Intel ACE CPUs

    On September 23, 2026, AMD compiler engineer Dipesh Sharma sent a four-patch series to the GCC mailing list. It adds support for AVX10V1AUX, an auxiliary x86 instruction-set extension defined in the AI Compute Extensions (ACE) specification, and a new -mavx10v1aux compiler flag. The patches are...

    LLVM 24 Adds AMD AVX10_V2_AUX Support for FP8, FP6 and FP4

    AMD's support for AVX10_V2_AUX, a new x86 instruction-set extension that converts data between standard floating-point and small AI formats such as FP8, FP6 and FP4, was merged into the development branch of LLVM 24 on Monday, September 22, 2026. Clang developers can now target it with a new...

    Linux 7.2 Drops TSC-Less x86 and Ends i486 Kernel Support

    Linux 7.2 now treats the x86 Time Stamp Counter, or TSC, as a mandatory CPU feature when building the kernel, completing a cleanup that removes support for processors too old to provide it. The practical effect is narrow for mainstream PCs and servers: virtually every x86 machine still running a...
