Because I do not know English well use translation program.
I hope to be understood.

What do you think about this computer?
Select it for chess?

Intel Xeon E5-1620 (3.60GHz - Turbo Boost 3.80GHz, 4C/8T, 10MB Cache, 130W)

I am interested in specifically how to play chess.

"I am interested in specifically how to play chess. "

If so...most any computer is overkill...unless you are wanting the program to play chess FOR you. Save money, get a good midrange computer and use that money for something else...maybe lessons from very good players who specialize in teaching/training. Don't be seduced into thinking that 'more' is better in this case.

The processor has 8 cores.

>The processor has 8 cores.

No, it only has 4 + Hyperthreading. It's not a good choice for chess.

its good in POGO chess. :roll:

there should be a 6th choice for not good

Yes. Basically this CPU isn't awful, but there are much better choices: if you don't want to spend much money you should consider a Core i5-3570k. If you want to pay a little bit more a Core i7-3930K is a good choice. A Xeon E5-1620 is a good choice in case you want to build an affordable server which has very good memory performance.

AMD CPUs have low initial cost, but their power costs seem to compensate. Is it possible to compare working out a total cost?
Parent - - By mindbreaker (****) Date 2012-12-25 08:56
Yes, that is a factor.  When you overclock those six-core Intel chips they also start to use a lot of power.  Any time you have to raise the voltage that adds considerably to power consumption.  My AMD FX-8350 did not require any increase in voltage to get to 4.4GHz. The FX-8150 did, but this new one; nothing extra.  It probably uses a little bit more just being overclocked, but it should be small compared to a chip that requires a voltage increase.  I am using water cooling so other people's results may very.

Power costs are also different in different locations.

FX-8320 125W
Intel Core i7-3770K 77W (4-core) Very impressive but 4-cores. Still should be pretty decent at chess, nothing like a 6-core though.
6-core processors though are 130W
The extreme ones use even more:

Will a 16 core intel xeon outperform a 6 core I7?
Parent - By mindbreaker (****) Date 2013-01-04 09:53
There aren't any the highest is 8-core.  (not counting hyperthreading which are mostly useless for chess).  There are two socket systems but Intel charges extra for Xeons that you can use that way and substantially more for ones that will go in a 4 socket system. The 8-core Xeon will almost certainly out perform unless it is impossible to overclock.

The answer to your question, from my experience, is NO !:grin:
I regularly play Engine-Engine Online matches....yet to lose to ANY dual-Xeon player... all ties....very happy with my overclocked 3930 k.
I think this is because once you start getting over 20,000 kN/s speeds like I do, there is very little (if any) ELO difference between say, 20-22000 kN/s speeds that I get and 26-28,000 kN/s speeds that the dual-Xeon players get, other factors (like Book, RAM) being equal.

> once you start getting over 20,000 kN/s

How much kN/s do you get on the start_position (and what overclock/cooler do you use)?
Parent - - By shrapnel (***) Date 2013-01-05 15:31
   I use the Opening Book for the first 10-12 moves...start_position speed depends how early my opponent deviates from the Book, forcing the Engine to kick in... anything between 18500 to 19500 kN/s .
I've o/c to a stable 4.8 Ghz with the latest Asus X79 Sabretooth BIOS and I use  Corsair H80 Liquid cooling and 32 GB RAM .... all assembled I'm proud to say by my own two hands :cool: !
I did consider getting a dual -Xeon 16 core System, but decided against it after reading reviews on the 'net... not really worth the hassles, even though I could afford it.
I've decided on my modus operandi as far as upgrading is concerned... simply upgrade to the fastest, single Intel Processor every alternate generation, that too, only if it is significantly faster than my present setup.
For instance, I've decided to skip the entire present Ivy Bridge line-up and wait for Haswell, that too , not any run-of-the-mill Haswell, but their flagship fastest 6 or 8 Core Processor, if and when it is released.... read on Fudzilla somewhere that Intel has lost interest in producing really fast 6-8 Core Processors because of lack of competition from a lackluster AMD !... Intel has really no motivation ( understandable) to do so as their present Flagship Processors are already so much better and faster than AMD Processors !

Well, I mean how many kN/s do you get on infinite analysis of the start position, with Houdini 3(say, after 1 min, and the hash you choose: 1GB?, 2GB?, 4GB?)?
