在 CentOS 系统中,可以通过几种方法查看 CPU 型号:
使用 lscpu 命令:
lscpu
输出中会包含 CPU 的型号信息。例如:
Architecture: x86_64
CPU op-mode(s): 32-bit, 64-bit
Byte Order: Little Endian
CPU(s): 4
On-line CPU(s) list: 0-3
Thread(s) per core: 1
Core(s) per socket: 4
Socket(s): 1
NUMA node(s): 1
Vendor ID: GenuineIntel
CPU family: 6
Model: 158
Model name: Intel(R) Core(TM) i7-7700HQ CPU @ 2.80GHz
Stepping: 9

L1d cache: 32K
L1i cache: 32K
L2 cache: 256K
L3 cache: 6144K
查看 /proc/cpuinfo 文件:
cat /proc/cpuinfo
这个文件包含了详细的 CPU 信息。你可以查找 flags 或 model name 来识别 CPU 型号。例如:
