[SOLVED] cores/threads on intel i7

[Steviebone]

I have a board lga1150 socket with an intel i7-4790K processor. Task manager shows 8 cores/threads. All the i7-4790k processors I see for sale say simply quad core. What gives? I can't find any lga1150's that indicate 8 core...

That's because there are none. If you want 8 cores then that's the wrong generation.

What you're seeing is correct, quad core with hyperthreading, 4
cores split 2 threads each core.

Make and model of your LGA1150 socketed motherboard? BIOS version for said motherboard at the time of writing? What OS are you working with? Yes the i7-4790 has 4 cores but 8 threads due to HyperThreading. It's possible that your motherboard might be compromised if it's showing 8 cores for a processor that has 4. Please try and inspect the CPU's socket for any bent or broken pins as a cautionary note.

No it doesn't...
It shows you 8 logical processors which is a very different thing.


Acthually it shows you 4 cores and 8 logical processors.

This is what task manager shows in W10 on my 4790K:

thank you for the replies. I believe it is showing 4 cores with 8 threads. Its running on an old win 2008 R2 server. In task manager I see eight process graphs. A standard quad core i7 4790K should replace the existing CPU.

Mine shows exactly the same.

You're either reading task manager wrong or task manager is simply wrong.

In Resource Monitor, a 4790k displays "8" CPUs...0 - 7
But that is not 8 cores.

Sorry, that was for OP. I know you know your stuff. 😀

OSes will indicate logical processors, or how many things they can stick a task onto. Since the i7 can handle two tasks at the same time, it shows up with 8 things Windows can schedule stuff on.

It's just easier to do things this way.
