Task manager only detects 2 cores on cpu when it should be 4

[AkoSiAdam]

my brother's pc has an a8-7650k he's about to give it away cause he's upgrading soon and i checked to see if his pc can perform well on apps used for school. i checked his specs and everything and i found something weird. task manager says his cpu has 2 cores instead of 4. i checked msconfig and it says it has 4 cores. pretty sketchy if you ask me

Thats expected. Its showing it as a 2c 4t cpu due to how its layed out with modules, and the cores not really being full cores.

 

Msconfig shows logical cores or threads, not hardware cores on the cpu.

From amds website it says 4c/4t, which means that there are 4 real cores, no?

2 cores share an FPU. 

So by definition it's hardware bound SMT, not done via software instruction sets or other.

And thus the reason AMD lost the law suit.

 

But technically, when X86 was first designed, it didn't have an FPU. But by definition was still an X86 core.
