What really advantage will Deep Rybka 4 have over the single core Rybka 4?
Parent - - By Gaмßito (****) [cr] Date 2010-05-15 14:04
The only advantage is that Deep Rybka 4 version can use all the cores you want (I think the maximum will be 2048), while the single core Rybka 4 version only can use 1 core.

Thanks for you answer.  How does having more core make Rybka stronger?

It runs much faster.

She can do different things at really the same time (and it is not trivial to do this in a real efficient way)
and so given Tasks are solved earlier, ways to win are found earlier, dangers are found earlier...

something like - "you would play better if have more heads" :)

i like, "It'd be easier if you were smarter."

I was not thinking like that, but more like simple explanation processor = head

For dualcore CPUs for example, using a single core will show only 50% CPU utilization while Rybka is thinking - remaining 50% of the CPU remains unutilized. Deeb Rybka can tap into the power of all the cores so that she can evaluate more moves in a given time.

For single core CPU however, if I am to guess I would say with 95% certainty it will not matter which version you are using - Rybka and Deep Rybka will be of equal strength.

AMD V-series processors and Sempron 140 can run the SSE4.2 version, which has no non-deep counterpart. That's only good for a 5% speedup, though.

Should be about 50 elo if you have a Dual, 100 on a Quad, and so on (number guessing since this hasn't actually been tested, CCRL results test without the workaround so SP Rybka looks much better than it should).

If I buy Rybka 4 by itself-and put it into a 2010 Rybka 3 Aquarium-Will I use any ability?    I use Rybka basically to analyse positions.

You can use all Rybka 4 features in Aquarium 3 (although you might want to check out the price difference for updating to Rybka 4 Aquarium).

Do you have Aquarium 2010 or Aquarium 3?
If you have Aquarium 2010 then you'd only need to buy Rybka 4 UCI, you'll get free GUI update to Aquarium 4 later today (if the patch is not delayed of course).

Do you absolutely have to use the Large Page function in Rybka 4?
Parent - By Dadi Jonsson (Silver) [is] Date 2010-05-27 08:08
No.
