another question ivan, and going on AMD, which produces powerful processors at low cost (even if heat and consume a lot), is there any solution for wrf multicore?

They are oriented on intel but if there is something that goes well amd I just might.

Powerful? :lol:

No really, there are several problems:
1) They are not powerful as Intel
2) They are not optimized for this type of computing
3) Intel compiler can't optimize code for them

So I never used them.

thanks ivan

In short, the 6800 and 6900 processors for WRF Are The Best?

From here mentioned, yes. Again, check this list:

Go from top down through the list. See first one that is in your budget. Purchase that.

Xeon 2630-v4 is cheap, has as many as 10 cores, it would be fine for wrf? yet I noticed that the 6800k surpasses having even less core .... maybe for the frequency.

I bet you prefer i7

Xeon 2630-v4 is cheap
Add motherboard prices to CPU always, then you can tell actual costs when you compare Xeon with Core series...

Ivan I like Asrock motherboard are oriented in many years has never given me problems and I was always satisfied.

I would take the Taichi, looks a bit

What I try to say is that you need to check if your chosen mobo supports that Xeon! It might be that cheaper mobos that will support Core 6900K won't support Xeon, but I'm not sure, check it out when comparing prices.

I understand, however, all depends on the budget. Thanks for the clarification, the opinions of others help a chose.

Ivan What do you think of 5820k? I found an interesting offer under € 400
