I don't agree at all about the Apple hardware statement. I never really took notice of all the Apple hype, but my cousin happened to be the local agent for Apple in my country and I ended up getting one of the new Macbook Pro's 13 inch with the new M2 chip. OMG !!! I cannot explain how incredibly impressed I was with the video editing performance of my spearfishing GoPro footage. It was dramatically faster ... I mean by several orders of magnitude ... than my souped up 8 core PC with a 1500 watt power supply and a 2080Ti card. Even 4K videos would scream through it like it was nothing. Totally amazing ... and all that without the laptop even getting warm ... with battery life that lasted the full day. So I personally was absolutely impressed with the performance.

I will add however that I hardly ever use that laptop except for video editing. I just can't get around the learning curve required to learn the new OS as I have been using DOS then Windows since my first PC. It does get me frustrated when I want to do a simple task ... but I am sure that can be resolved once I put some time and effort into it. I also don't know how well the M2 chip performs for chess as I was not able to run the Ipman test on it ... but if video editing performance is comparable to chess engine performance ... that thing will fly!
You describe a specialized use case with tweaked hw+sw encoding/decoding that is heavily optimized substantially by specialty hw used by proprietary sw... These use cases could likley be much more optimized for other hw if sw vendors prioritized limited hw-configs over general compatibility.

If Apple-hw was "truly" amazing it would also be able to do 3D raytracing, games, GPU-bound chess, AI, etc., etc. better, not only just certain specialized use-cases like video/sound-editing. If Apples CPU was better at much more than posting some boosted tweaked geekbench results. It would perform much better on Stockfish, Ethereal, Dragon, Hiarcs, Berserk, Koivisto, etc., etc.

Running Linux like Asahi on it makes it easier to compare apples-to-apples... and M1/M2 is beaten quite badly by Intel+AMDs offerings. Not only in price/value but also in raw performance.

I tend to agree, with Apple it is really about Logic Pro + Final Cut Pro, HW+OS+App, limited/optimized use case, but I like the unified memory approach, CPU+GPU+NN-Engine, and the given memory bandwidth...if you prefer performance/watt, go for a Raspberry Pi ;)

Yeah, I believe you can get a Rasberry Pi these days for even less money than a Mac, with amazin perfomance per watt running silent :-D

This morning I'm allowed to start from pole position on PlayChess with Stockfish 15.0. Played with 7 Cores. After 140 games still no game lost. :lol:

After 179 games 5m+0s, on PlayChess this afternoon (test finished): :lol:

I made this version just for fun:

Stockfish 15 ext:
https://filehorst.de/d/euvtvDHx

Engine plays a little more aggressively, but is a little bit slower in search. With 110 solved positions, the engine ranks (unofficial) 3rd on my EN-Test 2022 list with 60s, along with Corchess dev. The success on PlayChess with only 7 cores (179 games a row) is no coincidence. I played with my Solista Attack opening book, which you can get on my homepage if you want to check the test as I did it. MinimumThinkingTime=100 (setting only online for PlayChess.com).

Interesting results at CCRL 40/15 rating list:

Stockfish 15.1 64-bit:3538 elo (666 games) +25 elo according to Stockfish 15 / +44 elo according to Stockfish 13
Stockfish 15.1 64-bit 4CPU:3525 elo (414 games) -6 elo according to Stockfish 15 4CPU / -1 elo according to Stockfish 13 4CPU
http://ccrl.chessdom.com/ccrl/4040/rating_list_all.html

The low number of games produces such interesting results.

The error margins are huge so I don't think you can read that much into it. Single CPU did OK on the blitz list as well.

The fact is that Stockfish is only optimized for Bullet. If you increase the level (or you take more cores, which is the case for me in practice) then the advantage to the previous version shrinks to zero.

This is true with any engine and balanced openings.
Fat Titz by Stockfish, the engine with the bodaciously big net. Remember: size matters. If you want to learn more about this engine just google for "Fat Titz".
