Inventor 2015 CPU requirements for large assemblies

[pcingo]

Hi all,

I'm looking for a high performance hardware configuration (large assemblies) for Inventor 2015.

I had a look to Hardware and system recommendations reported here.

But it is not clear to me what "dual six core processors" means. This because about CPU requirements is also stated: "12 cores total, hyperthreading not recommended because Inventor does not take advantage".

What I understand is that I need a 12 core processor because hyper threading is not totally supported. If this is true, why to say "dual six core processor"? I'm a little bit confused...

I must buy an expensive 12 core processor or I can achieve top performaces also with a 6 core/12 thread processor?

Thank you in advance
