That's around 30kNPS, without overclocking. With maximum overclocking, selectable in software, that would be around 43kNPS.
If you build and sell
Unfortunately, the EU Waste Electrical and Electronic Equipment Directive (WEEE) has effectively banned tiny scale production, something also felt in the model railway sector. However, that doesn't apply for things you'd build yourself, and there is a sister project for affordable hardware: https://github.com/d3rvita/ct800-pcb
Actual dedicated computers are very weak.
Millennium Chess (Germany) has an interesting lineup with the Chess Genius, Chess Genius Pro, Chess Genius Exclusive, and The King Performance - the latter one with de Koning's legendary engine. Staff includes Hegener and Weiner, well-known from the old Mephisto era.
My chess computer passion last since many years. 30 years ago I have even talked with Richard Lang when the Italian importer organized the World Computer Chess Championship 1987 WMCCC in Rome and I was writing chess computer articles for Torre & Cavallo chess magazine (the socials were far to be invented, so I have interviewed by email Crafty author Dr. Robert Hyatt asking him when a computer would be able to beat a GM. It was apparently only a dream, but today it's normal ) I have also met Ossi Weiner in his shop in Munchen. I have owned a Tasc Chess Machine with de Koning's The King and Gideon from Ed Schroeder, Novag Forte, Mephisto Exclusive with Rome 68020 module, Fidelity Elite Avantgarde AS and a lot of Saitek Kasparov computers up to Kasparov Reinassance

Wow Ras!
Since the ARM64 build is 100 times faster (3000 kNPS on average), I tried CT800 vs Ethereal 13 github (1 CPU or it crashes) estimated ELO 3200 and the result is surprising!!! 1000 Elo more on Win 11 under Mac mini M1

Indeed - I'm more than astonished because the CT800 is only a mid-range engine while Ethereal is top league. I wouldn't even expect the CT800 to hold a single draw. Looking into the PGNs, all CT800 wins were because Ethereal forfeited on time - and losing 50% of the games on time is unheard of for Ethereal. There must be something with the setup that causes trouble for Ethereal.
My friends and I would like to see on the M1 Apple Silicon:
-much faster Stockfish
-ARMfish
-Cfish
-ASMfish
-the 500 CCRL engines
-retro chess emulator engines!!
It’s taken me ages to get 326 Engines on my Raspberry Pi 4 & Picochess & keep them updated.
This includes 144 of the CCRL Engines, all 30 Lc0 versions, 15 Turing type Engines, 09 Remote engines running on another platform, 15 NNUE Engines, 110 MAME Engines, play back any saved game plus some of the classics with PGN Replay & the ability to play online via FICS or Lichess.

Wow, that would take some time ……

Good luck,

I'm interested on Raspberry Pi 4, too!! (I run Ubuntu 20.04 ARM64 that is compatible) could you give us the link of the ARM64 engines compiled by you? (and the thread to follow you, if possible)
I've managed to compile Fat Fritz 2.0 github for Mac M1 following a step by step linux tutorial by the very kind & skilled cpeters (that I think actually is busy) http://talkchess.com/forum3/memberlist. ... le&u=12967
simply changing:
make -j build ARCH=armv8 for Ubuntu ARM64 and Raspberry PI4
to
make -j build ARCH=apple-silicon for macOS Big Sur M1 NATIVE
...Maybe I could also learn how to do it for Mac M1 from you

I've just visited your wonderful list with all the chess computers you own. So, being off topic here, I have created a new post about vintage computers and softwares http://talkchess.com/forum3/viewtopic.p ... 47#p905047
