Re: AMD BMI2 question

It works, but not well. Use 'modern' compiles.

Leela and GTX 1660 ti

Can anyone tell me, based on the reviews today, whether Leela will run well on the GTX 1660 ti? On the one hand they say that there are no tensor cores, but the editor of Anandtech says in a tweet that there are dedicated FP16 cores. Is that the same thing? I'm not up on graphics cards at all - neve...

Re: Syzygy 7 piece GUI support

I'm told Chessbase 15 should do so shortly.

Re: Wasp 3.50 by John Stanback available!

Which of these to use with a Ryzen chip? He cites the -modern version in the bench, but if it's for Haswell forward, doesn't that have bmi2 isntructions?

Re: Stockfish 10 and 2nd Gen Ryzen Question

The 2500U has four cores and eight threads. https://www.amd.com/en/products/apu/amd-ryzen-5-2500u I'd set the cpu to four threads, matching your number of physical cores. I don't think hyperthreading is worth it, especially on a laptop. You could set to three if you wanted to keep some processing po...

Re: Stockfish 10 and 2nd Gen Ryzen Question

Use popcnt or modern, depending on who did the compile. BMI2 is comparatively slow on Ryzen.

Re: My non-OC RTX 2070 is very fast with Lc0

Has anyone benchmarked the Tesla P100 with Lc0? You can rent time on Amazon AWS in a Windows environment - so you can setup the engine to run in the ChessBase Cloud - for like $1.20/hr with 1 P100.

Re: My non-OC RTX 2070 is very fast with Lc0

Well, NPS per $ but also in terms of 'value card.' $800 on a video card is not in my budget. I'm also looking for less power-hungry options, and wondering about how much 3gb vs 6gb ram (with teh 1060) would make a difference. I don't game so I've never bought a serious video card. Or maybe I should ...

Re: My non-OC RTX 2070 is very fast with Lc0

Perhaps off-topic, but what's the best value card one might get to run Lc0? GTX 1060?
