lscpu는 다양한 최대 CPU 주파수를 나열합니다.

이것은 lscpu 버그입니까? 어떻게 고치나요?

~$ lscpu

CPU op-mode(s):                  32-bit, 64-bit
Byte Order:                      Little Endian
Address sizes:                   46 bits physical, 48 bits virtual
CPU(s):                          20
On-line CPU(s) list:             0-19
Thread(s) per core:              1
Core(s) per socket:              12
Socket(s):                       1
NUMA node(s):                    1
Vendor ID:                       GenuineIntel
CPU family:                      6

CPU min MHz:                     800.0000

이것은 Intel i7-12700이며 CPU 최대 MHz를 다음과 같이 나열합니다.6300.0000

그러나 Intel 웹사이트를 확인해보니 다음과 같은 내용이 나와 있습니다.
