Existem dois processadores para minha CPU, processador0 e processador1. processor0 contém dois núcleos cpu, procesor1 contém dois núcleos cpu também.
Isso significa que existem quatro núcleos de CPU na minha CPU?

    

Answer 1

Existem dois núcleos na sua cpu. Mas para o sistema operacional, ele pode aparecer como 4 núcleos devido ao hyperthreading (se o seu cpu suportar).

Answer 2

Seu processador contém 2 núcleos. A maioria das informações, incluindo a contagem de núcleos, de / proc / cpuinfo é sobre o processador inteiro, não cada núcleo.
