Melihat informasi CPU dengan Command Prompt di Windows

Mengetahui spesifikasi dan fitur dari CPU komputer bagi anda system administrator yang biasanya melakukan manajemen komputer berbasis Windows hanya dengan command prompt akan membatasi software yang bisa digunakan. Apalagi anda ingin mengetahui secara detail apa saja yang didukung CPU komputer tersebut seperti virtualisasi, mode 64-bit dan sebagainya.

Anda dapat memanfaatkan tool dari Microsoft bernama Coreinfo, fungsinya adalah menampilkan informasi mengenai prosesor komputer pada command prompt. Cara menggunakannya cukup mudah, download dan extract isinya, kemudian jalankan command prompt dan arahkan ke lokasi aplikasi Coreinfo dan selanjutnya dengan mengetikkan coreinfo maka informasi mengenai spesifikasi dan fitur CPU yang terdapat pada komputer anda akan muncul.

Berikut adalah hasil dari perintah Coreinfo pada netbook saya:

Tanda asterisk (*) menunjukkan fitur tersebut didukung oleh CPU yang terpasang di komputer dan tanda minus (-) menunjukkan fitur tersebut tidak ada.

Perintah Coreinfo juga menerima parameter berikut yang bisa digunakan:

• -c ?? – Menampilkan informasi mengenai core (inti) prosesor.
• -f?? ?- Memunculkan data untuk fitur yang ada pada core CPU.
• -g?? ?- Memperlihatkan informasi untuk grup.
• -l ?? – Menampilkan data mengenai cache prosesor.
• -n?? ?- Menampilkan informasi dari node NUMA.
• -s?? ?- Menampilkan informasi untuk socket CPU.
• -m?? ?- Menunjukkan cost akses NUMA.
• -v?? ?- Menampilkan hanya fitur virtualisasi. Bisa membutuhkan hak administrator untuk prosesor Intel

Secara default bila hanya mengetikkan coreinfo tanpa parameter maka semua parameter kecuali -v akan digunakan.

Informasi yang ditampilkan menurut saya cukup lengkap, tinggal kita memahami fitur – fitur yang tersedia saja masalahnya. Tapi secara keseluruhan tool CoreInfo mampu melakukan tugasnya dengan baik tanpa hambatan.
