Doubling the processor speed,that means we can get extra approx.65 Elo

According to majority voting results,i see that Houdini 2.0c x64 should be rated around 3100 Elo

1)In case of aprox.300 Elo diffrence:
Code:
--------------
Kns      Elo
--------------
14413    3100
7206     3035
3603     2970
1801     2905
900      2840
450      2775
225      2710
112      2645
56       2580



According to my estimations,Houdini 2.0c x64 should be rated at least 3300 Elo

2)In case of +500 Elo difference:
Code:
--------------
Kns      Elo
--------------
28827    3300
14413    3235
7206     3170
3603     3105
1801     3040
900      2975
450      2910
225      2845
112      2780
56       2715





Note also that Houdini,Rybka,Critter (on Intel Pentium MMX 233) will be played with:
-one core
-32 bit versions
-no sss4 versions
-no large pages
-less hashtables...

That means (in both cases),on Intel Pentium MMX 233:
-the above top engines are expecting to be performed approx. 2500-2600 Elo !!!

First you have to understand a bit of computer architecture before making any analysis.
Frankly speaking with multiple cores NPS doesn't mean shit, you have to first figure out that.
12 times higher NPS on 12 cores in reality means only 120Elo points compared to single core and all that only if SMP is done really good for the given engine.
Then all the things that you listed (32b, no sse4, no large pages) already participate in NPS that you measured (they just increase rough speed, not quality of play). The only thing that plays a role is hash table size. However, since NPS is very low for Intel Pentium MMX 233, having relatively small hash is not a drawback at all (it's more like advantage, large hash would slow it down).
Finally, every doubling is not 65 Elo, there is a law of diminishing returns (if you search CCC programming forum, you'll find couple of discussion on that topic), where initially doubling was giving 70Elo, but today is more like 50Elo.

Also your starting point of 3300 Elo is too high, most probably it's around 3200 Elo in human rating.

So the real table would be something like:
Code:
--------------
Kns      Elo
--------------
28827    3200 2x Intel Xeon X5667, 12 cores
2400     3080 (single core = -120Elo)
1200     3030
600      2975
300      2915
150      2855
75       2790
37.5     2725

61       2770 Intel Pentium MMX 233
