Re: Dual RTX 2060 for Leela

I made some test to investigate how depends the nps value on the GPU core frequency. GPU: Gigabyte RTX 2060 Windforce OC (single GPU) Nominal (OC) GPU core frequency: 1770 MHz NVIDIA driver version number: 425.31 System: Ryzen7 1800x 8x4000 MHz, Windows 10 64 bits (2019 Oct) GPU tweaker: ASUS GPU Tw...

Re: Dual RTX 2060 for Leela

Just a sidenote: the NNcache can lead to somewhat misleading nodes per second counts. If you benchmark with a large value, and it does not fill it before the end, you will get significant NPS results, but they will not represent your actual speed throughout the game. Once filled, the NPS will drop ...

Re: Dual RTX 2060 for Leela

Also, forgot to mention, those results in your list are for different engines, ... This is the only point in which you are right. But the position of GPUs in the list are independent of the Leela version. Only the concrete nps value may change. Every parameters can be found in the "My non-OC RTX 20...

Re: Dual RTX 2060 for Leela

I made some new tests with Net 11250, Net 32930, Net 42033 based on the parameters of Albert Silver.

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

OK, something seems off. Why are the 2080 depth 17 nodes so many more than the depth 19 with the 2070? Maybe I am missing something. Thanks. Probably different nets used. But the speed should be fairly uniform with the latter test30 nets, so nps are probably fair to compare. I used 11250, which I h...

Thaks for the answer.
Where is RTX 2070?
:D
i7 6700K machine with 32Mb RAm.

its my machine for online chess-gaming.
I am passionate engine player @playchess and infinitychess.

C.K.
And what a success you use Leela and Stockfish?
Maybe you utilize the other two machines for CC games?

Re: Dual RTX 2060 for Leela

Basing on the common test data before we can make a list of RTX 2000 line GPUs. The common parameters are: NET: 11250 Backend: cudnn-fp16 Minibatchsize: 512 NNcachesize: 2000000 Other parameters are default The list: RTX 2060 OC max nps = 28646 (corres) RTX 2070 non-OC max nps = 29357 (Laskos) RTX ...
