So, IMHO, if you can use the 9.6.x version, more cores, more power

Hi all,

One of my system admins has approached me about replacing our production data warehouse system. I believe I know the answer, but would just like more opinions. He's giving me two options so far:

1) CPU = Intel e5-2637 3.5GHz 4 core with hyperthreading

vs.

2) CPU = Intel e5-2650v4 2.2GHz 14 core with hyperthreading

The rest of the specs are identical with 512Gb RAM and more than 2 Tb SSD drives. Our data warehouse is just shy of 2Tb now. I suspect the the first option would be more optimal as I don't think PostgreSQL can make effective use of a lot of processor cores. So fewer cores would be better optimized with the O/S. Can anyone weigh in on whether my assumptions are correct?
