<div dir="ltr">As Abdullah KAHRAMAN says its depend of what you need but in general aspects the number and speed of the cores is very important overall in resolution times, in this link: <a href="http://bit.ly/1dtl76F">http://bit.ly/1dtl76F</a> you found a simple benchmark made for me for a i5 core pc with 8GB of RAM and 500 GB in HDD, is in spanish but in Chile read spanish.<div>

Theoretically, a faster HDD would help with writing output. But if the<br>
history intervals you'll use are not extremely tight (i.e. in order of<br>
minutes or seconds), I don't think that effects the performance of WRF very<br>
much. However, not much for running the model, but during postprocessing, a<br>
faster reading can become quite important.<br>
<br>
RAM size would be crucial depending on your domain size (in terms of dx, dy<br>
and number of vertical levels). I guess a wiser choice would be increasing<br>
ram, if you are dealing with very large domains, rather than HDD. The RAM<br>
transfer rate (and that of mainboard) should be high as well, since maybe<br>
almost all performance depends on the CPU, RAM and the transfers between<br>
them.<br>
<br>
If there is no problem with the domain sizes or excessive postprocessing, I<br>
would improve the CPUs instead of any other hardware components. But maybe<br>
searching for benchmarks online would help better with your decision.<br>
