Hyperthreading on Nuc not fully working

Hello,

I have a NUC7i7BNB, board version J31145-302, BIOS NBKBL357.86A.0063.2018.0413.1542 running Win10 x64 pro.

(I have just now updated all the software as it would never update in the past using the Intel tool. I finally went and updated the BIOS manual to the latest as of today. Then I updated all other drivers via the tool and am 100% updated).

Problem I have is the I only see 4 threads. I should see 4 Cores and 8 threads, should I not? My Mac that is bootcamped sees 8 cpus. Yes, I have Hyperthreading Enabled in the BIOS (Performance, Processor, and Intel Hyperthreading is Checked). I also confirmed that in msconfig | advanced the processor checkbox unclicked.

The only way I found out about this is the new chess program I purchased only sees 4 processors while on my Mac it sees 8.

Any help is appreciated!

Thanks,

-Tom

The NUC7i7BN NUC has a Core i7-7567U processor, which has 2 Cores and 4 HyperThreads. Bottom line, you are seeing exactly what you are supposed to be seeing.

Thank you Scott. I just thought that all i7-xxx processors were 4-core / 8 thread capable. Lesson learned each day,

(I confirmed on Intel site). Even my wife's old laptop that's an i7-2670 something has 4 cores, 8 threads. Guess I should have done more homework on the Nuc's.

Thanks again Scott.

You have to look carefully. Embedded processors (which have 'U' at end of processor number) can have different core and thread counts.
