time-to-depth : no need more threads and better frequencies ? Q62XTq6
engine = stockfish 14.1, modern release, default settings, hash 1GB, no sygyzy
position = startpos
command = go depth 26
I ran 10x each command to take an average time-to-depth.
All configurations seem to tell : at a moment, the time-to-depth doesn't reduce even with more threads or higher frequencies !?

very interesting, but how does it compare at higher depths, such as 35 or 40?

to run 10 times "go depth 40" from startpos with 1 thread, 2 threads, etc will take lot of time...

exactly, this is why you need more threads 
 your conclusion: All configurations seem to tell : at a moment, the time-to-depth doesn't reduce even with more threads or higher frequencies 
is wrong

not sure so first i will redo it with 10x "go depth 32"

Except the "12 threads" configuration, all configurations seem to tell again : at a moment, the time-to-depth doesn't reduce even with more threads or higher frequencies.

D32 log files

Almost same test here .
Conclusion : no need more threads and better frequencies in order to get a better time-to-depth (lazySMP)

More threads and better frequencies seem help with an old stockfish version using YBW (so before SF7)
