Here is new test and here are the results:
Conditions:
Intel Core i7-980X 3.33GHz
Hyper-Threading OFF
Large Pages OFF
Arena 2.01 Chess GUI
512 MB hashtable size
132 Tactical positions
Houdini 4 Tactical x64 6 cores, 6 seconds/move performed: 83/132
Houdini 4 Default x64 1 core, 30 seconds/move performed: 52/132
Houdini 4 Default x64 6 cores, 6 seconds/move performed: 46/132
Stockfish 160715 x64 1 core, 30 seconds/move performed: 46/132
Stockfish 160715 x64 6 cores, 6 seconds/move performed: 44/132
More Details,
Used unsolved positions in 3 sec/move 1 core by the current chess engine versions
Note that (for better comparing) I decided to test Houdini 4 6 core 6 sec/move too
As I expected, SF 6 cores 6sec/move performed very close to 1 core 30 sec/move
Note also that,
I tested SF 6c 6sec/move with 128 MB hash too: 43/132
Also SF 6c 6sec/move tested with 1024 MB hash: 42/132
What I can say more,
We can not use any right 'formula' in case of comparing the hardware speeds !
It all depends on our used conditions...some engines perform better some worse...
But however (in case of measuring the hardware speeds)
Stockfish 290815's KN/s values seems to be not bad choice...
Of course, one of the best choices is that: running similar test suite positions
Or running engine matches in Auto232 mode or via LAN etc...
