Yes my i7 CPU has 6 cores and 12 threads.

One other thought, only slightly relevant.

If, toward the end of rendering a frame, you find that you are waiting 
for one or two blocks to finish. Setting Render_Block_Size to a smallish 
value allows all of your cores to work on the blocks instead of being 
idle. I generally use +BS8
