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: Select all
--------------
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: Select all
--------------
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: Select all
--------------
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
First of all thanks for your all replays
Actually i respect your opinion,but however i dont agree with you
Yes...i am trying to understand this:
-I see that you are just a commentator-no more no less SORRY !
And its will be great if you publish some useful links(maybe yous),where other chess friends (including me) can benefit from your work
But next time no more comments please-instead of only bla,bla,bla,i prefer real facts !
But however,it seems you missed to visit/read some of my activities for Comptuter Chess
And here are some of them:

For more details about the differences between 32-bit,64-bit,SS42...versions,see also the useful sites e.g CCRL,CEGT,SWCR...
This time,i hope this helps...
A little note more (due to i am tired of comments):
-I have already announced a Challenge: Top GM to play with my machine (unfortunately no any contact so far,exception only comments...)
And no patience too see a such Challenge,remember also that in case of less than 500 Elo,i promised that i will donate the GMs with 5000 USD
But another issue is that,who will donate me,if i will be the Winner (i mean,if there will be more than 500 Elo)
That's All
Kind Regards,
Sedat
