libcpuid15 binary package in Ubuntu Jammy amd64

 libcpuid is a small C library for x86 CPU detection and feature
 extraction. Using it, you can:
 .
    - get the processor vendor, model, brand string, code name,
    - get information about CPU features such as: number of cores or logical
      CPUs, cache sizes, CPU clock,
    - check if the processor implements a specific instruction set such as
      the SSE2, 3DNow!,
    - execute the CPUID and RDTSC instructions (portably!)
 .
 This package ships the libcpuid shared library.
