AFAIK, the “cores” are 64-bit ALUs that can split into 32-bit
pairs to run 32-bit code.
So an i7 has four x 64-bit cores that also work as 8×32-bit CPUs.
Threads are an OS construct, unless you want to refer to them as
“real” vs. “virtual”, in which case you’d have up to four
64-bit threads or eight 32-bit threads.
I run VMWare, and I’ve never really bothered to figure out how it
does its CPU mapping. I think I’ve given it two cores and 2GB of RAM
and it does fine running Win 7.
(My base system is a Mac with a 2.8 GHz i7, 16 GB of RAM, and the
latest OS X.)
I read and understood everything you said until i read the above line
and I forgot everything except "My base system is a Mac with a 2.8 GHz
i7, 16 GB of RAM, and the latest OS X.".
That is a serious system. Is that the Mac Book Pro 15.4 with 512MB SSD?

Hi,
If an Intel CPU has 4 cores and 8 threads will it look like 8 cores
to VirtualBox when assigning resources to a guest?
If so is there a way to determine which is a tread and which is
actually a core?
