As you can see there isn't a standart ratio for Lc0 vs Stockfish matches. It changes according to the Lc0 nets and time control.
lc0-0.25 + SV-20b-t40-1541 @ GTX 1650 vs 8 MNPS SF-latest (nps at starting position) at TC=10'+2"

Ratio is changed due to Lc0 nets and time controls. Lc0 is more weaker at short time controls
so how many NPS needed?

LC0 @ low power GPU

There is quite a lot information about running Leela at TDP>120+W GPU (RTX class)

I wonder what is good low-power (TDP<=65...75W) GPU for Leela

Is GTX-1650 best in this sub-75 class (as of 2020-Q2)?

What is SF-dev ratio for LC0@GTX-1650, how many NPS need SF-dev to be roughly equal?

Re: Ryzen 2 and BMI2?

By that, I mean publishing through API that their hardware supports (for instance) PEXT, the compilers will generate it. There are many software vendors (proprietary software with binaries) which just ignore existence of non-Intel CPU. They used to look for string "GenuineIntel", but after some cou...

Not sure if you can buy one in US.
Any phone, even $99 Redmi 8A (Qualcomm Snapdragon 439) will be faster in Droidfish than AMD E-series

Re: SSD SATA Recommendation

Even with these disadvantages many of the tests show Tests show expected behavior : IOPS of software RAID-0 degrade with number of array members. 4 SSD are 4x times slower than any individual SSD If you put 2 SSD into garbage bin, speed will increase twice not a rocket science, but take 5 stages: d...

Re: SSD SATA Recommendation

a 3 or 4 drive raid array with 10-15Gb/sec and ~3,000,000 IOPS sustained is likely needed so actually we are talking about software RAID-0 (under Windows it will be 99% built-in raid support, Aorus just GUI front-end) Here they tested Samsung 983 DCT (1TB, NVME PCIE x4 version) https://www.pugetsys...

Re: SSD SATA Recommendation

Did you even bother looking at the links to the cards I posted? Read the first one I did. Also I've downloaded PDF Manual from manufacturer. It states it's not a RAID at all. It's just piece of plastic to mechanically handle up to 4 M.2 cards. Each M.2 card is traced to x4 number of lanes. That is ...
