The developers of public firmwares... live from that... they earn up to 3% of the hashrate worked... it seems that this time bitmain once again beat them to it!! better efficiency in their new chips.. with their firmware in their own way.. Voltage and frequency!!
I wouldn't say they beat the aftermarket firmware, the report I saw shows the best efficiency at 25w/th with about 20% loss in the total hashrate, Artemis3 mentioned 20w/th, I am sure Vnish folks would probably report similar numbers, of course, you still need to consider the dev fees you pay for those two versions, but auto-tunning will always beat static figures in term of efficiency.
IMO, S19 pro is pretty much effienct by default, the efficiency gains will affect the total earnings for most people with low power rates, a 20% loss in hashrate or even 10% is no joke, it will be good for those who pay higher rates, some serious maths need to do before choosing whether to go for the upgrade or not, the same math that needs to be done when choosing to go custom or not, different things work differently for different people.
Saw the Twitter last night. Just signed into Bitmain and only firmware I'm seeing is from 12/15 for the Hydro.
There is no need to sign in, just go to
https://shop.bitmain.com/support/download select S19 pro or S19j pro, the latest firmware has (Support S19 Pro low power mode) in it with publish date 19-12-2022.
