It seems more of a QoI issue. Most Intel chips maintain synchronized (same rate of change) TSCs. That knowledge is encoded in the Linux kernel:

   /*
    * Intel systems are normally all synchronized.
    * Exceptions must mark TSC as unstable:
    */
   if (boot_cpu_data.x86_vendor != X86_VENDOR_INTEL) {
    /* assume multi socket systems are not synchronized: */
    if (num_possible_cpus() > 1)
     return 1;
   }
