Confused about my i7's core amount?

[scruffies]

I thought it had 4 cores and 8 threads, I thought I knew this kind of stuff! Turns out I didn't, because every reporting software I have shows that I have 8 CPUs, not 4 (or 12 including threads for that matter)

So why is it acting like this? Or why is it showing I have 4 cores and 4 threads, if that's even what it's doing. I'm confused!

You have 4 cores and 8 threads indeed. Some software reads it as 8 cores though.

[The Official Czex]

It's counting logical cores, not physical cores.

 

Logical core = thread

[Arty]

4 c 4l means

4 logical

4 hyper threaded 

[Flight1sim]

Software will read the Thread value as cores sometimes, which is why it says 8 cores

It's 4 cores 8 threads is not 12 cores. It's 4 real cores essentially split to act like 8 cores if that makes sense. Not 12

4 cores and 8 threads means that there are 4 physical cores in the CPU that are acting as 8. Adding them to make 12 is not correct.

[scruffies]

I was not assuming they are the same thing-I'm just wondering why it shows 8 instead of four. Is it only showing my threads, not my cores? I'm quite confused

 

Also, logical core = thread? Right

Yes it does only show your threads.

Your OS doesn't differentiate between a core and a thread.

[Wyzzy Moon]

You don't have 4 cores AND 4 threads, threads don't exist next to cores, cores have treads.
each core has 2 threads. So 4 cores, 8 threads.

The difference between a physical and logical can't be discerned. 

 

Yes, a logical core is a thread. 2 per physical core.
