Still didn't buy the CPU so I throw in another question: i5 8400 or ryzen 5 1600?


The issue with the i5 is the expensive motherboard. You can use a B350 with the Ryzen - I recommend the Asus Prime Plus, which you can overclock in the OS with the Zenstates utility.

Choosing the right chipset has nothing to do with these things you mention here. I could do these things just as well on a 10 year old Intel Celeron laptop.

Of the things you mention, only the part about having "the best player" could be affected by the chipset. And the importance of that, if you are primarily an OTB player, is certainly up for debate.

My present desktop computer is at least 5 years old, and optimized for silence rather than speed, and I do not feel the least bit at a disadvantage because of that that.

If the opposite became true, I would propably also quit chess. Smiley


Let's just admit that for some of us (like me) it's simply fun to know you have a strong engine--just as it would be fun to have a car that went faster than you could ever drive it. Irrational, but true.

When owning the proper chipset is an important tool in playing chess is when I know the game has passed me by and its time for other things a life..

So long and thanks for all the fish.


Funny - for me, it makes the game more exciting. (And expensive, but who's counting?) I always have the best player in the world at my beck and call to answer questions. I always have a training partner, in lobotomized form given my playing strength, to play out positions against. Each day I can download new games from elite events to peruse. And there's always a new video on Youtube to watch while I'm on the treadmill.

Thank god it isn't.

Back in 1998 I build a computer far stronger than anyone else I knew had. Optimized for chess calculations, it would calculate away on various positions when I wasn't at home. Either at critical positions or playing engine tournaments in my favorite dubious opening lines.

What good did it do for my chess? None at all.

As far as I know, the Ryzen is cheaper but not as reliable (including for gaming, though it was't the initial question). I heard that Intel recently reduced their prices as a result, though, so I'd say that the difference in performance would be worth the investment, but as always you should do your own research.


For chess engines, Ryzen blows Intel out of the water. Having more cores per $ spent is important, but just as important is the fact that Ryzen's version of SMT (Infinity Fabric) is more efficient than Intel's hyperthreading, making full use of all threads a net plus with most engines.

The chessbase link for 3/2017 supports what you're saying and if I'd know this I might have bought a computer with the Ryzen CPU instead of one with i7-7700k (which is still much better than the last computer I had).

It will be hard to use Houdini on Amazon EC2 as there is copy protection involved in the install.

I've used Komodo and Stockfish on EC2 under Windows installs. Very easy. Just drag your Chessbase 12/13/14 install file over, don't register it, and set up your engine in the Engine Cloud on the EC2 instance. Very efficient way to get huge iron if / when you need it.

That said, I haven't done this since I got the Ryzen7 1700.

Thank you for bringing that up. It is an option, of course, and in Houdini, that I bought, you can make use of these cloud engines free or paid but I still prefer to have my own hardware. It is not a big deal since I am not a pro but just wondering where to put my money, that's all. If ryzen7 1700 is a better buy than ryzen5 1600, chess wise, that's my only question.
An interesting topic is also the hyperthreading thing; I searched a bit about that and it seems, from my findings at least, that it still doesn't help much.

It is possible to run a chess engine on Amazon EC2 instances in the cloud. Naturally, you would have to pay for this. But it does make the choice of buying computers much simpler, and paying per hour is much cheaper overall than paying for a beefy computer!

If there's enough interest I can elaborate on how it's done. It's not too complicated.

Brief overview:

1) On Mac and Linux (not sure about Windows) UCI engines talk to GUIs via standard streams. This means that to spoof a remote engine to look like a local one, all you need to do is write a script that connects and launches the remote engine. Hand this script to your chess GUI, and it will be none the wiser that the engine is actually running elsewhere.

2) Cloud based CPUs don't necessarily all live on the same hardware. This extra latency can hurt chess programs (although I haven't investigated to what degree). You can provision all your cores to be on the same hardware on AWS, but not in most other cloud providers. This costs a bit extra.

This is news ... I thought that for chess engines it is not recommended hyper threading. So it has changed ...
Nice to know. In any case I am still waiting for some serious prove to go with R7.
