Re: top engines vs 2400 engine knight odds matches

You can try this with Stoofvlees as well (you should have a copy). I expect it to do even better than lc0.

Re: Will be the new Shredder a Hybrid-Engine?

I am never going to spend hundreds of euros for a graphic card and cooling and electricity bills just to be able to run NN engines. It seems rather likely that increasing NN support in new CPU architectures and improvements in NN engines will make the issue moot. lc0-CPU-LD2 is a reasonably strong ...

So only Houdini, Komodo, Fire, Ethereal and Xiphos are without neural networks.
Pure A/B Engines seem to be out.
Fire has a NN version, it played in TCEC.

more about where the people spending the ICGA's money want to vacation this year!
It seems to be where the IJCAI (to which the ICGA linked itself?) is holding its conferences, more than anything the ICGA itself wants.

Re: CEGT - rating lists July 14th 2019

Note that Stoofvlees doesn't support pondering (yet), so I would expect it to be weak in pb=on rating lists.

Re: Ryzen 3000 series is out

Yes, otherwise I don't understand the scores. Do they say if they allowed the Boost? i9 9900k on 1-2 cores can go to 5.0GHz, while Ryzen 3900X 1 core to 4.6GHz. If they allowed the boost, many single-thread benchmarks will look bad for Ryzen in this comparison. Leela is a curiosity in this benchmar...

Re: Ryzen 3000 series is out

I'm already talking about the revised numbers. The original ones (now deleted) showed that the 3700X was the same speed as the 2700X, which obviously couldn't be true.

In the new data it clearly gains, but not enough to catch Intel.

Re: Ryzen 3000 series is out

AnandTech included SPECint2017 benchmarks, which include Deep Sjeng: https://images.anandtech.com/graphs/graph14605/111160.png The results were...surprisingly bad, i.e. clearly worse than Intel cores. I wonder why. This is one thread benchmark? It's actually a bit confusing: "Moving on to the 2017 ...

I wonder if the BMI2 slowdown is finally fixed.
PEXT/PDEP still take ~18 cycles. You don't want to use those.
