what CPU is better for chess analyse

I assume you might be referring g to what CPU gives the highest nodes per second?

Here are some benchmarks for Stockfish https://ipmanchess.yolasite.com/amd--intel-chess-bench-stockfish.php

I believe Lc0 may be able to use GPU as well.

The Ryzen 9 7950k will analyse to the same depth 10% faster than the Core i9-13900K based upon benchmarking of the hardware.

thanx I will buy it

AMD threadripper 3970X would be best for chess analyse?

Yes if you can afford it.

At your level it doesn't matter. Any computer 15 years old will beat any super GM.

The OP wants to know what CPU will provide the fastest performance for analyzing a game. I don't think they want to play against the computer. They want to analyze a game as quick as possible.

I just bought a laptop with an I 9 ultra. The idea behind it was to simply avoid crashing. I do a lot of chess work, and I mean a lot of chess work. So typically I will run two or three engines at once on a position to get the best assessment and find unique ideas. I like the idea of having extra lower power cores run the background stuff while I analyze. I have had crashing and freezing issues in the past. I'm not sure what overall is better but so far so good. Seems like I'm getting the results I want without the risk of losing all my work to sudden crashes. I'll keep everyone here posted though. I just started using it.

@chess_rehab in your use case I think cloud engines might be a good option. It allows you to offload some of your analysis to cloud engines that will likely be faster than yours. Fritz and chessbase support this I think,

Cloud engines are going to be MUCH slower than any UCI (stockfish) engine you can download and run on a modern high end CPU, through something like Chessbase or Arena or another UCI compatible client.

The only thing that comes close are the stockfish engines that load through the browser but use your own CPU for calculations, rather than the cloud system (and this has to be toggled as an option--and this can cause overheating or BSOD issues if your system is not properly tuned).

Yes
