Per determinare il tipo di cpu e le informazioni relative alla stessa linux mette a disposizione alcuni comandi da terminale.
Per una rappresentazione più compatta
$ lscpu Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian CPU(s): 6 On-line CPU(s) list: 0-5 Thread(s) per core: 2 Core(s) per socket: 3 Socket(s): 1 NUMA node(s): 1 Vendor ID: AuthenticAMD CPU family: 21 Model: 2 Model name: AMD FX(tm)-6300 Six-Core Processor Stepping: 0 CPU MHz: 1400.000 CPU max MHz: 3500.0000 CPU min MHz: 1400.0000 BogoMIPS: 7046.72 Virtualization: AMD-V L1d cache: 16K L1i cache: 64K L2 cache: 2048K L3 cache: 8192K NUMA node0 CPU(s): 0-5
per avere tutti i dettagli relativi processore si può utilizzare
cat /proc/cpuinfo
Le ampie informazioni possono essere selezionate utilizzando grep. Pertanto per evidenziare i core presenti si può utilizzare:
$ grep "model name" /proc/cpuinfo model name : AMD FX(tm)-6300 Six-Core Processor model name : AMD FX(tm)-6300 Six-Core Processor model name : AMD FX(tm)-6300 Six-Core Processor model name : AMD FX(tm)-6300 Six-Core Processor model name : AMD FX(tm)-6300 Six-Core Processor model name : AMD FX(tm)-6300 Six-Core Processor
Per visualizzare le informazioni relative alla cpu e del hardware in generale si può utilizzare anche un programma ad interfaccia grafica come hardinfo. hardinfo una GUI GTK+ per visualizzare le informazioni hardware in linux
