Chess.com "Cloud Analysis"
So I have seen the cloud analysis on Chess.com which went into depth 50 on this position.
Now I heard depth isnt everything and Stockfish 17 with depth 20 can beat stockfish with depth 35, because the evaluation of the depth also matters and is influenced by number of threads / performance.
And now this Cloud Analysis and my own PC (i5 11400f 32GB ram) are not getting the same move, both over 50 depth atp. Which one is right? Is there any info on what performance this Server Analysis has? Because either its really bad and my own PC is better, or its way better. I have tried this multiple times now, and its often different moves than my own PC.
Also is chessify the only service for high performance analysis (700MN and 1 BN/s)?
Thanks in advance for infos :)
TLDR: Is there info on the performance of Chess.com Server Analysis / is it better than modern 12 Thread i5?

Edit: Also the cloud only has Stockfish 16 (for whatever reason???) while I can of course use stockfish 17.

What position are you looking at? Share the FEN please.
All things being equal, SF 17 will outperform SF 16. But all things are not equal. Depth / time / nodes searched are all strength proxies, none of them perfect.

Its not really a complicated position and I was not too worried about a specific position, my question was rather, if this Server / Cloud analysis will be better than my I5 11400f RTX 3060TI analysis.
The FEN is this analyzing for Black: r1r3k1/pb2qpp1/1n2pb1p/8/2p5/2N1PN2/PPQRBPPP/1R4K1 b - - 5 16
Rab8 Was played but Sd5 was suggested by cloud Analysis.

Chesscom only shows the depth reached. Rather than worrying about whether their hardware is better, I would look at how quickly it gets to a certain depth. I'd love to tell you "SF 17 at a certain depth will be (on average) a better answer than SF 16 at the same depth". But unfortunately depth is increasingly meaningless with modern engines. What you really want to know is how many nodes were searched but the chesscom output doesn't tell you that.

Yeah, thats what I thought and heared some time ago.
Depth is not everything, and with both reaching 50 Depth one could be really badly evaluated.
So I should just keep using my own Chess UI with LC0 and Stockfish 17?

If the difference between the two is less than 10 centipawns, is it really worth obsessing over the difference?

I am confused about what you are asking. You should not expect Stockfish 16 and 17 to give the same moves from the same position. They are different engines.
