The chessbomb website, which I use religiously, is now using what I believe is the latest Stockfish build, 140127.

http://abrok.eu/stockfish/93f95cc936690 ... _sse42.exe

How much stronger is this than DD? And where and how can I find out for myself?

Thanks

From Stefan's RL, I calculate the approx. ratings difference
as around 30 points.

So you're saying Stockfish has gained around 30(!) rating points between the time DD came out and now, which is only a couple of weeks?

WOW!

Right.
Only as a reference, the average Elo improvement per week for Stockfish in the last 10 months is roughly 3 points. Smile

Tom.
I would not be surprised for 4-5 points gain per week in latest 6-8 weeks.
But watch out for so-called regressions for few intermediate compiles.

Stockfish DD was released on Nov 29, 2013. That's about 8 weeks ago :D

In my testing SF DD is about 30 elo weaker than previous SF.

Hi Gerold,

Are you sure that the new Stockfish is using all cores of your computer? 30 points is a lot, but could be expained when it is using only one core and the older Stockfish more. Number of threads now has to be set to the number of cores you want it to use, and the settings have to be stored in some way. How depends on the GUI you are using.

He's talking about "SF DD" being weaker than "previous SF". Depending on what he means by "previous SF" this might well confirm the results of the other tests.

Using SF 4-32bit. on dual core computer. This version is 30 elo stronger, after 500 games (1min.10 secords TC) then SF DD. Same books and same conditions as other engines in this match. Maybe to few games.
