Re: First chess benchmarks for the Intel core i9-10980XE emerge

Why would you use the BMI2 scores for Ryzen when it scores significantly better on popcnt? Aren't you just shooting yourself in the foot? Maybe your doing that on purpose! You can do really nice things with BMI2 especially PEXT/PDEP but if you are not a programmer it probably doesn't matter. Benchm...

https://lab501.ro/procesoare-chipseturi/review-intel-core-i9-10980xe-cascade-lake-x/10 That benchmark shows less performance than what is expected from a Ryzen 3950X AM4 at 105 W TDP! :D :D :D At 33% greater price why on earth would you buy that? Regards, Zenmastur Really? I haven't seen any real w...

Re: First chess benchmarks for the Intel core i9-10980XE emerge

Very impressive result. How much does it cost? Intel set the price at $979, basically it is just the i9-9980XE with some security mitigations and deep learning boost (8 bit multiply add accumulate 32 in 1 cycle), the clock frequencies are somewhat higher too. When it is available in the Netherlands...

Re: On-line engine blitz tourney October

I've put the server on a Hyper-V virtual machine on a machine with a core i5-9400 processor (a really fast processor, draws hardly any power when idle). Last time the performance was already good, next time it will be even better. There are still some bugs and omissions in the server software, maybe...

December 7/8, the 56th Programmer Tournament and 39th User Tournament will be held.
This coincides with the ACTA tournament from Charles Roberson, maybe not so handy!

Re: Ataxx

What does the protocol looks like? If somebody want's to play he needs more information than the connection details alone.

Re: Ataxx

It is a piece of cake to change my old Othello/Reversi program in such a way that it can play Ataxx. I don't know how difficult it is to let the Chess-server I just put up recognize something like Ataxx. HG is the only one with experience in adding variants to the server.

Re: kiwipete perft position

I have a strange scheme, I use the piece values as index into the bitboard arrays. I use the following constants: White = 0; Black = 1; Empty = 0; Pawn = 1; Knight = 2; Bishop = 3; Rook = 4; Queen = 5; King = 6; const white_pawn = White | Pawn << 1; const black_pawn = Black | Pawn << 1; etc. PieceTy...
