Atomic Pi Brings Intel to Single-Board Computers
Digital Loggers introduced Atomic Pi, a single-board computer that combines
the small form factor of a Raspberry Pi with an Intel Atom processor.

Atomic Pi features a quad-core Intel Atom x5-Z8350 with a 2M cache,
a 480MHz GPU and 1.92GHz maximum clock speed.

2GB DDR3L-1600 memory,

Linux comes pre-loaded

subreddit : https://www.reddit.com/r/Atomic_Pi/

board costs $34

bundled the Atomic Pi as a Full Developers Kit featuring cameras, a power supply
and two Atomic Pi boards for $95

24 of the single-board computers for $696.

sold via the Digital Loggers store as well as Amazon  (out of stock , USA only)

-------------------------------------------------------------------------------------

based on my experiences of raspberry pi and asmfish on Intel-Atom tablets
I estimate 1800 kn/s in Ipman's list at $40 und ~8W

it should be possible, to insert a booting micro-SD, with a list of to-be-analized positions
or a cutechess-cli - tournament storing the result on the card without monitor, keyboard, mouse

you may run ~24 these on a good multi-power-supply at ~$1000 in total on SD-cards at 120-200 Watts
and 40000 kn/s in total for some weeks for analysis or tournaments.
For shorter runs it's quitw some work to prepare,insert,remove,and manage the results.
It may work for correspondence chess, one Pi per game, tou attach the TV to the corresponding when
you have to make a move, and keyboard or mouse, when  you enter the opponent's move.
Just one TV and mouse should be enough with suitable software.

if you are in USA.
Shipping to Europe is difficult and may cost another $1000 with the current trade-war

someone may be able to build clusters with these ...

I guess that most correspondence players will check their moves with at least 16 cores running at 24 hours on two or more machines (different engines).
An atom pi could not possibly keep up with that quality of move choices.
On the other hand, such a setup would be very nice for a tournament setup with many (e.g. in the configuration you describe) top engines playing tournaments to test out openings for holes at long time control.
I could see such a setup having real value for chess.

But I would be surprised to see such low powered entities driving correspondence analysis for unique move choices in games.

This also looks interesting Bitscope scalable Raspberry Pi Clusters.  http://cluster.bitscope.com/solutions  :cool:

for chess the "Atomic" version should be 5-10 times faster

There are diminishing returns however. On 24 hours analysis per move, the difference in analysis quality/elo between pi and the 16 core machine would probably very minimal at least on traditional engines. At high depths engines like stockfish tends to shuffle their moves and doesn't really add to the quality of analysis on the root position most of the time. A good corr player would most likely play out the moves then retro analyze it or better yet just cross analyze with lc0 on a good gpu, much better than wasting hours on one position.

yes, for important correspondence tournaments you would use powerful PCs.

But some players have several tournaments running in parallel, including lower level
qualification tournaments

you can also check several subvariants of a game in parallel - one variant per pi
I played 2 forum-games that way on 2-5 tablets, asmfish under droidfish , depending on the position
reaching depth ~50-55(4) in average , but, well, it would be tedious without touchscreen
for each
