在Linux系统中，有多种方法可以查看CPU型号。以下是一些常用的命令：
lscpu 命令lscpu 是一个显示CPU架构信息的工具。
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
CPU MHz: 2800.000
BogoMIPS: 5600.00
Virtualization: VT-x
L1d cache: 32K
L1i cache: 32K
L2 cache: 256K
L3 cache: 6144K
NUMA node0 CPU(s): 0-3
cpufreq-info 命令cpufreq-info 是一个显示CPU频率信息的工具，也可以用来查看CPU型号。
cpufreq-info
输出中会包含CPU的型号信息，例如：
analyzing CPU information...
driver: acpi-cpufreq
CPU information:
driver: acpi-cpufreq
flags: hwmon
min: 800 MHz
max: 3.60 GHz
cur: 2800 MHz
cpuinfo_max_freq: 3600000 kHz
cpuinfo_min_freq: 800000 kHz
cpuinfo_transition_latencies: 19.50 ms
scaling drivers: acpi-cpufreq
available cpufreq governors: conservative, ondemand, userspace, powersave, performance
current policy: frequency should be within 800 MHz and 3.60 GHz.
The governor "ondemand" may decide which speed to use
within this range.
/proc/cpuinfo 文件/proc/cpuinfo 文件包含了详细的CPU信息。
cat /proc/cpuinfo
输出中会包含CPU的型号信息，例如：

power management:
dmidecode 命令dmidecode 是一个显示硬件系统部件信息的工具，需要root权限。
sudo dmidecode -t processor
输出中会包含CPU的型号信息，例如：
Handle 0x001C, DMI type 4, 42 bytes
