Is this a bug from lscpu? How to fix it?

~$ lscpu Architecture: x86_64 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 Model: 151 Model name: 12th Gen Intel(R) Core(TM) i7-12700 Stepping: 2 CPU MHz: 2096.531 CPU max MHz: 6300.0000 CPU min MHz: 800.0000

This is an Intel i7-12700, it lists the CPU max MHz is 6300.0000

However, I checked the Intel website, and it lists:

Max Turbo Frequency 4.90 GHz Intel® Turbo Boost Max Technology 3.0 Frequency ‡ 4.90 GHz Performance-core Max Turbo Frequency 4.80 GHz Efficient-core Max Turbo Frequency 3.60 GHz Performance-core Base Frequency 2.10 GHz Efficient-core Base Frequency 1.60 GHz
